dissolved air dlotation

-


Wastewater is driven into a Dissolved air flotation  system and mixed with a stream of “white-water”, which is recirculated Any solids that don’t float will sink to the bottom of the Dissolved air flotation tank.

Water from the DAF (DAF DISSOLVED AIR FLOTATION) that's super saturated with dissolved air. As these two watercourse mixes together, microscopic bubbles attach to solid particles, giving them enough buoyancy to travel to the surface of the Dissolved air flotation tank.

The simplified water flows out via either side of the Dissolved air flotation unit. A number of this water is employed within the recirculation loop while the remainder flows out of the vessel for discharge or further treatment.

Typically, with the utilization of chemical coagulation prior to the Dissolved air flotation, up to 95% reduction of TSS, BOD, FOG is often achieved or up to 75% reductions without chemicals. Dissolved air flotation is are often used as a primary step before biological wastewater treatment because it is going to remove an honest portion of the nutrient load and thus reduce the dimensions of the biological treatment system, alongside providing a good quality of effluent.

  #SludgeDewatering   #ComboUnit   #Thickener +BeltFilterPress Krofta Engineering Ltd, India  Introduces newer version, enhanced capacity “Triple Wire Belt Filter Press” which is a COMBO UNIT (Thickener + Dewatering) Triple-Wire Belt Filter Press. This combo unit can work even at 0.8% sludge consistency without using separate thickener for dewatering Primary & biological secondary sludge generated at Industries & municipal plants. > In built flocculator comes as a standard supply with this new design > Low power consumption compared to other systems. The purpose of sludge dewatering is for waste minimization & to achieve overall cost efficiency for disposal. This machines has several combined processes added into one unit and it involves different applications such as chemical conditioning, gravity drainage and mechanical shearing and compression effect to remove water and dry up the sludge. Today, belt filter presses are widely used and it has become a standard for g

Tannery Wastewater Treatment

-
Image
  Tannery wastewaters  are highly complex and its treatment is administered by physical or chemical or biological or a combination of those methods. From the review, it is often concluded that physical/chemical processes combined with the organic process is the better option for the treatment of tannery wastewater. The tanning industry is one of the oldest industries on the planet and therefore the problem of treatment and disposal of those wastes is perhaps as old because of the industry itself.  Tanneries wastewater  effluent is treated in many various ways. There are situations during which a private tannery applies all the below-described  wastewater treatment  steps on site. In other situations a private tannery may apply (on-site) only pre-treatment or a neighborhood pre-treatment or no treatment in the least, sending the effluent to a centralized effluent treatment plant. Nevertheless, treatment is important thanks to the wide selection of toxic effects on the environment caused
