DAF in Slaughterhouses

-



The use of physical/chemical methods and also the application of contact-assisted activated sludge process are investigated. These tests were dole out in a very 310-m3/d plant. The analysis of plant performance was supported the standard of treated water created and also the value of the plant relative to every configuration.
 The results show that a 2 stage dissolved air flotation units combined with contact-assisted activated sludge method would alter the plant to satisfy the discharge standards projected by the Kuwait Environmental Protection Authority.

 Fat/oil/grease is reduced by concerning 84 %; suspended solids area unit reduced by concerning seventy two across the first stage DAF. The contact-assisted activated sludge reduces the ultimate effluent COD to but 250 mg/L. Finally, substantial amounts of total suspended solids area unit removed throughout the ordinal stage DAF method. 

The world analysis for a well-designed and properly operated contact-assisted activated sludge method is bestowed during this paper.

The composition typically depend upon the quantity of animals killed. In India, there square measure concerning 3500 abattoirs (CPCB, 1992). Most of them discharge their effluent directly into sewers. In few cases, the waste is with chemicals coagulated and occulated before discharge into the sewers. The treatment of effluent from shambles, meat process and packing industries has been reviewed

  #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 beco...

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 effe...
