Xylem launches DAF Solutions in South Africa
Xylem, a global water technology company focused on solving complex water challenges, recently launched its new Dissolved Air Flotation (DAF) products and services for the South African market.
I n an event hosted at Xylem Africa’s headquarters in Kempton Park, Johannesburg, the company unveiled its DAF equipment and services, delivering reliable wastewater treatment to key sectors such as mining, municipalities, agriculture, aquaculture, food & beverage, paper & pulp, chemical manufacturers, and pharmaceutical companies. DAF is a critical pre-treatment and solids-separation system within broader wastewater treatment system. It can operate as a standalone solids-separation step or complement downstream biological, filtration, or reuse systems to help achieve site-specific compliance and reuse objectives. The compact and modular design enables deployment in constricted and crowded sites. Xylem also provides excellent DAF rental options that support smaller and seasonal projects. “We are very excited to bring cutting-edge DAF solutions to our local customers. Xylem has introduced our DAF solutions to several other markets, where they have become a big hit among companies of various sizes. They appreciate the logistical benefits of DAF’s compact designs and convenient deployment, supported by our expert technicians. South African organisations in the private and public sectors can now also leverage DAF to expand their choices for water treatment and recycling,” says
Chetan Mistry, Strategy and Marketing Manager at Xylem WSS (AMETI). What is DAF? Xylem’s DAF systems use Hellbender™ pumps to release microscopic air bubbles that, following appropriate coagulation and flocculation, attach to suspended and destabilised colloidal particles, enabling their separation from the water phase which can be skimmed away. The DAF technique efficiently removes Total Suspended Solids (TSS), Fats, Oils, and Greases (FOG), and particulate- associated biochemical oxygen demand (BOD) from wastewater streams. These systems offer an effective solution for a wide range of applications, including: • Thickening of biosolids • Product recovery from wastewater • Treatment of industrial wastewater to meet site discharge limits • Polishing of biological treatment effluent (algae and phosphorus removal) • Pretreatment to reduce loading on downstream biological treatment systems • Clarification of biosolids downstream of aerobic and anaerobic
