Water scarcity and wastewater management have long been pressing concerns across South Africa, and Xylem, a globally recognised water technology company, has just made things a great deal more manageable.
The company officially launched its Dissolved Air Flotation (DAF) equipment and services at its Africa headquarters in Kempton Park, Johannesburg, marking a significant step forward in accessible, practical wastewater treatment for the region.
The launch drew attention from a wide range of industries that deal with the daily challenge of treating and recycling water responsibly. Mining operations, municipalities, agricultural businesses, aquaculture farms, food and beverage producers, paper and pulp mills, chemical manufacturers, and pharmaceutical companies are all in the frame as potential beneficiaries of this technology. It is a broad reach, and deliberately so.
At its core, DAF is a pre-treatment and solids-separation system designed to slot into existing wastewater management frameworks. It works as a standalone unit or as part of a larger treatment process, sitting alongside biological treatment, filtration, and water reuse systems to help facilities meet compliance targets and achieve their recycling goals. What makes it particularly attractive is its compact, modular build, which means it can be installed even in tight or congested spaces where traditional systems simply would not fit. Rental options are also on the table, making it viable for smaller operations or those with seasonal demands.
The science behind DAF is clever but straightforward. Xylem's systems use Hellbender pumps to generate microscopic air bubbles that, after the water undergoes coagulation and flocculation, latch onto suspended particles and drag them to the surface where they can be skimmed off. The result is water that is significantly cleaner, with total suspended solids, fats, oils, greases, and biochemical oxygen demand all reduced efficiently.
Three models are available, the RT-50, RT-100, and RT-240, catering for flow rates ranging from 100 to 1,000 GPM. Each unit is built from durable stainless steel, comes with an integrated flocculation tube, and includes a pre-wired control panel that makes setup relatively straightforward.
Chetan Mistry, Strategy and Marketing Manager at Xylem WSS (AMETI), was candid about what this launch means for local customers. "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."
The support offering goes well beyond simply supplying equipment. "Xylem's expert staff and our experienced partners customise each solution as required. We deliver and manage components such as mixer tanks, weir tanks, pumps, and conveyors, as well as catwalks and accessories. Our skilled technicians can support on-site staff or run the process on behalf of our customers," added Mistry.
For too long, fully industrialised water treatment felt out of reach for many South African organisations, put off by the cost and operational complexity involved. Xylem's DAF range changes that conversation considerably, offering a flexible, scalable entry point into serious water management without demanding enormous upfront commitment. Whether a business is running a pilot programme or upgrading an established treatment system, there is a configuration to suit the need.
The launch plants Xylem firmly on the map as a hands-on, solutions-driven partner for industries and municipalities that are serious about using water wisely.
