The Modular Wetland System Linear™ (MWS Linear) represents a pioneering breakthrough in stormwater technology as the only biofiltration system to utilize patented horizontal flow, allowing for a smaller footprint and higher treatment capacity. While most biofilters use little or no pre-treatment, the MWS Linear incorporates an advanced pre-treatment chamber that includes separation and pre-filter cartridges. In this chamber sediment and hydrocarbons are removed from runoff before it enters the biofiltration chamber, in turn reducing maintenance costs and improving The MWS Linear has been successfully used on numerous new construction and retrofit projects. The system’s superior versatility makes it beneficial for a wide range of stormwater applications treating rooftops, streetscapes, parking lots, and industrial sites. The MWS Linear can be used for the following applications: industrial, residential, streets, parking lots, commercial, mixed use, agricultural, reuse, low impact development and waste water. Performance The MWS Linear continues to outperform other treatment methods with superior pollutant removal for TSS, heavy metals, nutrients, hydrocarbons and bacteria. Since 2007 the MWS Linear has been field tested on numerous sites across the country. With its advanced pre-treatment chamber and innovative horizontal flow biofilter, the system is able to effectively remove pollutants through a combination of physical, chemical, and biological filtration processes. With the same biological processes found in natural wetlands, the MWS Linear harnesses nature’s ability to process, transform and remove even the most harmful pollutants. performance. Applications

Orientations Side-By-Side The Side-By-Side orientation places the pre- treatment and discharge chamber adjacent to one another with the biofiltration chamber running parallel on either side. This minimizes the system length, providing a highly compact footprint. It has been proven useful in situations such as streets with directly adjacent sidewalks, as half of the system can be placed under that sidewalk. Internal Bypass Weir (Side-by-Side Only) The Side-By-Side orientation places the pre- treatment and discharge chambers adjacent to one another allowing for integration of internal bypass. The wall between these chambers can act as a bypass weir when flows exceed the system’s treatment capacity, thus allowing bypass from the pre-treatment chamber directly to the discharge chamber. External Diversion Weir Structure This traditional offline diversion method can be used with the MWS Linear in scenarios where runoff is being piped to the system. These simple and effective structures are generally configured with two outflow pipes. The first is a smaller pipe on the upstream side of the diversion weir to divert low flows over to the MWS Linear for treatment. The second is the main pipe that receives water once the system has exceeded treatment capacity and water flows over the weir.

Flow By Design This method is one in which the system is placed just upstream of a standard curb or grate inlet to intercept the first flush. Higher flows simply pass by the MWS Linear and into the standard inlet downstream. End-To-End The End-To-End orientation places the pre-treatment and discharge chambers on opposite ends of the biofiltration chamber, therefore minimizing the width of the system to 5 ft (outside dimension). This orientation is perfect for linear projects and street retrofits where existing utilities and sidewalks limit the amount of space available for installation. DVERT Low Flow Diversion This simple yet innovative diversion trough can be installed in existing or new curb and grate inlets to divert the first flush to the MWS Linear via pipe. It works similar to a rain gutter and is installed just below the opening into the inlet. It captures the low flows and channels them over to a connecting pipe exiting out the wall of the inlet and leading to the MWS Linear. The DVERT is perfect for retrofit and green street applications.

Configurations Curb Type

The Curb Type configuration accepts sheet flow through a curb opening and is commonly used along road ways and parking lots. It can be used in sump or flow by conditions. Length of curb opening varies based on model and size. Grate Type The Grate Type configuration offers the same features and benefits as the Curb Type but with a grated/drop inlet above the system's pre-treatment chamber. It has the added benefit of allowing for pedestrian access over the inlet. ADA compliant grates are available to assure easy and safe access. The Grate Type can also be used in scenarios where runoff needs to be intercepted on both sides of landscape islands. Vault Type The system’s patented horizontal flow biofilter is able to accept inflow pipes directly into the pre-treatment chamber, meaning the MWS Linear can be used in end-of-the-line installations. This greatly improves feasibility over typical decentralized designs that are required with other biofiltration/bioretention systems. Another benefit of the “pipe in” design is the ability to install the system downstream of underground detention systems to meet water quality volume requirements. Downspout Type The Downspout Type is a variation of the Vault Type and is designed to accept a vertical downspout pipe from roof top and podium areas. Some models have the option of utilizing an internal bypass, simplifying the overall design. The system can be installed as a raised planter, and the exterior can be stuccoed or covered with other finishes to match the look of adjacent buildings.

Bio Clean 7

This modular system provides the same treatment train concept as the industry leading Modular Wetland System Linear™ (MWS Linear) - screening, separation, & biofiltration combined with the capacity to reduce and control water volume in a more efficient way when compared to traditional downward flow bioretention systems.

B i of i l ter Product s

Configurations One of the biggest challenges of the implementation of LID and bioretention/biofiltration systems is the associated space requirements. The large space requirements of traditional bioretention systems can cause design and feasibility issues, increasing the overall cost to comply with local and state stormwater regulations. The WetlandMod marks the first technological breakthrough to address how we comply with these regulations. The goal of the system is to minimize footprint and land costs associated with traditional bioretention/biofiltration systems. This is achieved by utilizing horizontal flow technology and combining it with traditional downward flow, therefore maximizing the surface area for a given footprint. The WetlandMod system is constructed from modular precast concrete structures. The system comes standard with a curb-type pre-treatment structure, including internal bypass. The biofiltration chambers can be made in any length and shape (shown below) to allow for easy integration with parking lot island designs. The system comes in two standard widths, 4 feet (18” minimum media requirement - San Diego County) and 5 feet (24” minimum media requirement - Los Angeles County). Footprint Reduction Up To 61% Over Traditional Bioretention Systems (Example: Planter Boxes, Rain Gardens, Biofiltration). Designed To Minimize Required BMP Footprint and Maximize Buildable Space

The WetlandMod™ system is built upon the concept of horizontal flow biofiltration, which was first introduced by the MWS Linear. Horizontal flow works with gravity, not against it, to prevent clogging, standing water and other problems associated with traditional downward flow bioretention systems. Bioretention systems have an inherent flaw, the force of gravity. As stormwater runoff carries pollutants into the system, including sediments and hydrocarbons, they are deposited on top of the bioretention media where it accumulates and quickly clogs the filter media. It has been documented that sediment accumulation from just a few storm events can completely clog a bioretention system. This leads to drastically reduced infiltration rates, expensive maintenance burdens, and safety issues associated with standing water, depressed landscaping and vector control.

Sediments accumulate on top of the media leading to clogging

Water Flow Unimpeded

Water Flow Impeded

The WetlandMod overcomes these challenges by utilizing pre-treatment, a horizontal flow bio-filtration bed, and orifice flow control. The initial surface of the media bed in the WetlandMod is oriented on a vertical plane, as opposed to horizontally, therefore running parallel with the force of gravity as opposed to perpendicular. This simple concept increases surface area, reduces BMP footprint, prevents clogging and leads to an enhanced overall system with lower maintenance costs. The WetlandMod can utilize various media blends to meet local stormwater bioretention media specifications. The system is also available with an organic-free WetlandMedia™ to prevent nutrient leaching and maximize pollutant removal.

Treatment Stages Pre-Treatment

The Kraken Filter's membrane filter cartridge provides high flow rates and over 170 sq. ft. of surface area. This much surface area allows it to operate at a loading rate of only 0.05 gpm per sq. ft. to ensure maximum performance and minimum maintenance. The Kraken Filter’s low loading rate successfully overcomes high maintenance requirements and frequent clogging issues often found in other filter systems advertising high loading rates. Each membrane filter cartridge is lightweight, washable, reusable and more sustainable than typical granular filled media cartridges. By eliminating the need to purchase new granular media and dispose of spent media, the Kraken Filter provides lower life- cycle and maintenance costs. Each filter cartridge is equipped with easy-to-grab handles and is pressure fitted, allowing it to be quickly removed, washed clean and re-attached without the use of tools. • Loading rate of 0.05 gpm/ sq.ft. for minimal maintenance • Membrane filter cartridges can be easily removed & cleaned by hand • Built-in pre-treatment chamber captures trash, sediments, debris and hydrocarbons • Filter cartridge dries out between storm events to prevent bio-film growth which can cause clogging and other performance issues • NJDEP On-line Installation approved • 89% TSS removal (NJCAT PSD) • >50% phosphorous removal (expected; varies with particle size) • >50% total metal removal (expected; varies with particle size) • 90% TPH (expected) • 99% trash removal Advantages and Performance • No granular media replacement • High flow rates & maximum surface area

To reduce loading on the membrane cartridge, runoff is initially passed through the pre-treatment chamber to capture trash, hydrocarbons and sediments. Once runoff is pre- treated it is directed to the filter chambers for primary treatment. Membrane Filtration-Fill Up During the fill up process a riser tube prevents flow through the membrane cartridge until the water level nears the top of the cartridge. This ensures loading is evenly distributed over the vertical height of the cartridge. Membrane Filtration- Peak Capacity As the water level reaches the top of the membrane cartridges, flow through will begin. The riser tube creates an upward flow path within each cartridge to increase performance. Treated water then passes down the riser tube and collects in the underdrain manifold and flows to the discharge chamber.

Bypass An optional internal bypass is available with most system

configurations. When flows exceed the treatment capacity of the system the water level rises and goes into bypass. High flows are conveyed from

the pre-treatment chamber directly to the discharge chamber to prevent scouring of fine sediments captured within the filtration chamber.

The Bio Clean Water Polisher is an advanced stormwater treatment system utilizing an up flow media filter with built-in pre-treatment.

Med i a Fi l ter Product s

This patented design provides double chambered separation to remove large to fine sediments from stormwater runoff. This configuration prevents clogging challenges found in downward flow media filters. The Water Polisher includes an oil skimmer containing hydrocarbon booms to capture and permanently retain oils and grease. The design of the skimmer allows the booms to float up and down with the changing water level for enhanced performance. The up flow filter utilizes an advanced drain down system that allows for passive backwash of the media following each storm event. Backwashing the media removes accumulated particulates from the surface, preventing clogging. Backed by an 8 year unlimited warranty, the up flow filter assembly is constructed with 100% high grade stainless steel for superior durability and longevity. The Bio Clean Water Polisher is a favored solution nationwide among civil engineers, municipalities and developers for its simple media replacement procedures and internal bypass option. Water Polisher AN UP FLOW MEDIA FILTER

Treatment As water enters, head pressure builds behind the internal weir to generate the force needed to operate the up flow filter. The water passes over the first separation chamber, settling out sediment. As it passes to the second separation chamber, it encounters an oil skimmer which removes hydrocarbons before water is forced under the skimmer and into the up flow filter chamber. As water rises up it is forced through the media filtration bed for primary treatment before exiting the system.

Advantages and Performance

Dual-stage treatment (separation & media filtration)

Passive Self-Cleaning Once flow into the system subsides, the water level in the system will start to fall. When it reaches the upper effluent side of the up flow filter it can no longer discharge. The remaining water within the filtration media is forced downward as the drain down filters continue to treat and discharge stormwater. This passive back wash action releases pollutants that would otherwise contribute to long-term clogging and performance issues.

The Watergate ARS is a revolutionary automatic retractable screen that blocks trash and debris from entering storm drains during dry weather flows and light to moderate rain.

Trash Screen Product s

Watergate ARS The Watergate ARS is a revolutionary automatic retractable screen that blocks trash and debris from entering storm drains during dry weather events and light to moderate rain flows. During these periods the screen remains closed and locked to allow removal of trash and debris by routine street sweeping operations. During periods of increased flow and heavy rain, the screen will unlock and open to allow runoff into the storm drain to prevent flooding. When the water flow subsides, the screen will return to the closed and locked position. The Watergate ARS features a patented front-pivot design to bias the screen toward the closed position and provide for more effective closing and locking. The positive closing force vastly reduces the possibility of debris becoming trapped under the screen and preventing it from fully closing and locking. Patented front-pivot design provides a natural positive closing force - Superior to springs, magnets and counter weights found in traditional units Receptors in the control arms allow the Watergate ARS to manually lock open from the street. A simple push upward on the screen returns the unit to normal operation Simplicity of design makes for a more cost- effective solution - Only 5 individual fabricated parts, 8 total Routine street sweeping is the only maintenance required • • • Advantages and Performance •

• Water flows of approximately 2 inches or more will unlock and open the Watergate ARS • Positive force returns the Watergate ARS to the closed and locked position, to reduce the possibility of debris becoming trapped under the screen.

Operation Closed & Locked Position

Maintenance Routine street sweeping is the only maintenance necessary. The Watergate ARS will remain closed and locked during routine street sweeping and is not affected by the sweeping brushes. For added peace of mind, the Watergate ARS can be manually locked open before large storm events. This lock is easily engaged and disengaged by hand, via receptors in the control arms. Durable enough to handle routine street sweeping.

During dry weather flows and light to moderate rain, the Watergate prevents trash and debris from entering the catch basin. This allows routine street sweeping maintenance to address trash before it enters the storm drain system.

Open & Unlocked During Increased Flow During heavy rain events, increased water flows will unlock the Watergate’s screen, allowing it to open only as far as necessary to allow runoff to enter the catch basin and prevent flooding while still blocking larger trash and debris. This patented design intelligently prevents clogging and flooding issues often found with fixed screen systems. After any storm event, the screen will return to the closed and locked position automatically.

Bio Clean's BioSorb Booms are the industry’s leading solution for controlling oil contamination in storm- water runoff. These booms are used to control and absorb oil and hydrocarbons on any surface, including water. It can control oil spills and slicks in harbor dock areas as well as residential and industrial areas. Available in 2” and 3” diameters, booms of any length and custom sizes and configurations are available upon request. BioSorb’s oil absorbing polymers will not absorb water, which lends the material a unique usefulness for separating and collecting hydrocarbons from water mixtures. The polymer can commonly absorb from 20% to 200% or more of its own weight in chemical or petroleum derived liquids. BioSorb becomes dry to the touch shortly after absorption. Replacement Media

How Are BioSorb Oil Absorbing Polymers Unique? BioSorb oil absorbing polymers function by first attracting hydrocarbons to the surface of the polymer to absorb the liquid, followed immediately by internally absorbing the media into its structure. BioSorb oil absorbing polymers will not absorb water, which lends the material a unique usefulness for separating and collecting hydrocarbons from water mixtures. Most notably, the polymer can commonly absorb from 20% to 200% or more of its own weight of chemical or petroleum derived liquids. Furthermore, because of the unique absorption characteristic of the material, BioSorb becomes dry to the touch shortly after absorption. Applications • Stormwater filters

• Concentrate carrier material for liquid additives

• Removing oil or chemicals from contaminated water streams


• Controls and absorbs oil and hydrocarbons on any surface, including water • Controls oil spills and slicks in harbor and dock areas • Controls oil contamination in stormwater runoff

The Modular Wetland System utilizes a proprietary blend of bioretention media that

BioMediaGREEN™ is an amazing material changing the way we think of filtration media. Most systems utilize a granular media that needs to be contained, is heavy in weight and difficult to replace.

outperforms standard sand filters, bioretention systems and standard subsurface flow wetlands. WetlandMEDIA™ provides greater plant growth, moisture retention,

In contrast, BioMediaGREEN comes in lightweight blocks making it inexpensive to ship and simple to replace. This particular media is present in a few capacities within the MWS Linear stormwater system. First, it is utilized in the pre- treatment stage within the pre-filter cartridges. There is over 25 sq.ft. of surface area per cartridge, and the media itself removes over 80% of TSS and 90% of hydrocarbons. Another ultimate advantage of the pre-filter cartridges are that they prevent pollutants that cause clogging from migrating to the main stage, the biofiltration chamber. Second, the plant propagation layer of media bed on the surface of the MWS Linear creates a hearty layer that supports and sustains vegetation. Advantages • Made of various oxides to promote ion exchange of dissolved pollutants • 80% void space allows for double the contact time compared to granular media

evapo-transpiration, and pollutant removal while traditional bioretention media, consisting of compost/organics and sand, has been known to have negative effects – leaching nutrients. Advantages • No organics

• Removes phosphorus

• 48% void space

• Greater surface area

• Maximum evapo-transpiration

• High ion exchange capacity

• Light weight

• Excellent physical filtration and hydraulic capacity

• Perlite can also be used
