features include: • Superior, clog-free performance: The system delivers superior performance without plate packs, which can foul, col- lapse or clog, thereby increasing opera- tional uptime. • The robust, space-saving design features a rugged, heavy-gauge stainless-steel tank (available in 304 or 316 SST) that will not flex, while the tank’s rectangular profile ensures maximum space utilisation. • Ease of installation: The complete, skid- mounted design means no field assembly is required, simplifying installation. • Efficient whitewater system: The system uses an industry-leading and HELLBENDER ® whitewater system to cre- ate very small air bubbles, making the sys- tem both efficient and simple to operate. • Integrated and automated: A large inter- nal float hopper eliminates the need for an external float tank. The system also features an automated float hopper and settled solids auger. • •Optimised chemical mixing: An integral flocculation tube is equipped with three chemical injection ports, designed for op- timal mixing of coagulants and flocculants. • Reliability: Built with quality drive and pump components for long-term reliability. “From running pilots and proofs of concept for wastewater management plans to enhancing the efficiency of established treatment sys- tems and upgrading to cutting-edge treatment methodologies, Xylem Africa and DAF help
South African industries and municipalities solve water for all. “Xylem Africa and its partners can deliver permanent and rental DAF solutions, calibrated to a customer's specific requirements and op - erations,” says Mistry. Xylem's expert staff and experienced partners customise each solution as required. “We deliver and manage components such as mixer tanks, weir tanks, pumps and convey- ors, as well as catwalks and accessories. Our skilled technicians can support on-site staff or run the process on behalf of our customers," Mistry notes.
Water is humanity's most essential re- source. As water stress and costs increase, organisations are intensifying their strate- gies to ensure supply and compliance. For many, though, this prospect was out of reach due to the cost and cumbersome ownership requirements of industrialised water treat- ment options. Backed by Xylem’s engineering expertise and service capabilities, dissolved air flota- tion offers flexible, resilient options for wastewater pretreatment and reuse within integrated water management strategies. https://www.xylem.com/en-za/
