DAF unit with a capability of 20 m3/h, seen also: flocculant planning station and pipe flocculator

Thanks to the Innovative FADAR® technologies, our equipment generates a stream of micro-air bubbles that adhere into the flocs, elevating them towards the floor where by a scraper method eliminates the sludge mattress generated for the hopper that collects the sludge, achieving a reduction in complete suspended solids by approximately ninety%, cutting down COD, and acquiring a sludge dryness of all over six%.

Precisely what is a dissolved air flotation program? How does it operate and what's the difference between sedimentation and dissolved air flotation?

Building the ideal DAF technique in your application needs site visits, tests and pilot experiments to find out the true wants from the plant. A typical DAF process incorporates coarse filtration, physicochemical treatment method, and dewatering in the sludge prior to discharge or reuse.

Our impressive DAF procedure has the option to include an Increased floctube assembly to enhance contact time and boost substantially system performance. Now available configurations are listed underneath.

Helps ingesting drinking water obtain clarity and contributes to stopping issues related to style, odor, as well as doable formation of disinfection byproducts in the course of the water procedure.

DIFLOAT�?method contains various enhanced parts and procedure advancements that make it possible for for more productive hydraulics throughout the DAF flotation zone at excellent floor loading charges.

This floating sludge layer is then mechanically and constantly eradicated by a scraper system. The DAF process will produce a taken care of effluent pretty much freed from TSS, FOG and remove a significant portion of the BOD.

e. better recycle needs lower outflow and vice versa). Normally the pump control method is answerable for the recycle movement, meaning the effluent outflow must be controlled individually or associated with the pump program Command.

Countercurrent scraping �?for one of the most efficient separation of sludge through the effluent drinking water. This also allows for a lot more free of charge drinking water to decant prior to sludge removal.

Pump operation needs an appropriate air movement, pressure, and recycle move for optimum air saturation in the recycled water flow.

As a result of the continuous here advancements inside our patented aeration method, the Nijhuis i-AERATION technique plus the sludge thickening/scraper system Geared up on our DAF units will result in DAF flotation sludge using a significant dry solids material, therefore lowering sludge hauling costs.

Another option would be to exclude the plate pack technologies and choose Nijhuis Open up Flotation Device Technological know-how to make sure the unit can take care of better reliable loadings though continue to generating a high quality effluent.

An extremely similar course of action called induced gas flotation is usually utilized for wastewater treatment. Froth flotation is often Employed in the processing of mineral ores.
