High-speed dissolved air flotation equipment and technical solutions

In strategic cooperation with Niihuis of the Netherlands, we have introduced advanced high-speed dissolved air flotation (DAF) equipment and technology to provide efficient solutions for oil and phosphorus removal, biological sludge recirculation and separation, seawater desalination suspended solids pretreatment, and river water intake pretreatment. DAF equipment is classified according to its processing capacity and function into IPF (<135 m³/h), NPF (<500 m³/h), and GDF (activated sludge separation and recirculation, oil recovery).

Technical features

Strong processing capability

0-500m³/h (single unit), 1000-2000m³/h (large flow air flotation for concrete modules).

Wide range of applications

It is suitable for the treatment of various industrial wastewater, municipal sewage, seawater desalination, and river water intake.

High processing load

The maximum hydraulic load design can reach 45 m3/m2/h.

Small footprint

It adopts a unique built-in inclined plate separation design, which reduces the floor space by 1/3 compared to traditional air flotation.

Low operating costs

It features a high degree of automation, precise chemical dosing, a precision dosing system, and the ability to reduce the amount of chemicals by 30%.
