Continuous-flow aeroflotation water treatment plant - DAF system

NISKAE, with a design standard of its own, has developed a concept of modular aeroflotation plants for industrial water treatment. NISKAE offers a complete range of dissolved air separators and flotation units - DAF system - for the precipitation and physical separation of pollutants from water. Designed for industrial effluents of all types and flow rates from 1 to 50 m3/h, air flotation combined with coagulation and flocculation is an effective technique for removing pollutants and suspended solids from wastewater.

What is dissolved air flotation?

Dissolved air flotation (DAF) is used to remove suspended particles from treated water. DAF works by using pressurized air which, once in the water, transforms into millions of micro air bubbles that trap suspended particles, causing them to rise to the surface of the water to be scraped off.

Building on the success of the SW microstation range, NISKAE engineers set themselves the goal of developing a range of aeroflot water treatment plants - SDFLOT - applying the characteristics of the “NISKAE” design standard, i.e. an all-boiler unit made of polypropylene plastic, compact, above-ground and plug and play.

Our SDFLOT plants provide continuous wastewater treatment, combining coagulant and flocculant reagents with aeroflotation and surface skimming. The treatment unit comprises a pH control tank, a coagulation tank, a flocculation tank and an aeroflotation skimmer.
The unit is designed as a single unit for easy handling, and is combined with a reagent preparation and dosing station.

Depending on the quantity of sludge generated, sludge conditioning and dewatering is carried out either by a module of big-bag filter boxes or by a filter press.

SDFLOT units can be equipped for reuse and recycling of treated water by adding a clear water storage tank and the necessary filtration capacities.

Our SDFLOT range comprises 4 treatment units that stand out for their small size and high efficiency.

  • SDFLOT10 treatment station for flows up to 12 m3/h
  • SDFLOT20 treatment station for flows up to 20 m3/h
  • SDFLOT40 treatment plant for flows up to 40 m3/h
  • SDFLOT80 treatment station for flow rates up to 80 m3/h

As with our range of industrial water treatment equipment, the operation of our SDFLOT aeroflotation plants is fully automated and benefits from all the technological advances made by NISKAE engineers in terms of PLC control and communication via our own VPN solution.
