Sludge Dewatering & How It Helps

-

 


Accumulation of residue in the sewage treatment plant is called sludge. A sewage sludge can be substantial, semi-solid, or slurry sludge material that is produced as a by-product of the wastewater treatment process. The formation of sludge also occurs due to various factor, and one of the most common factors are Tannery wastewater.

Tannery wastewater is considered one of the most polluted sources. It can lead to environmental issues related to its high organic matter, suspended solids, and chromium. A sludge is mainly classified into two categories which are Primary sludge and secondary sludge. The mud which occurs due to the chemical precipitation, sedimentation, and the primary process is called primary sludge. In contrast, secondary Sludge occurs due to the activated waste biomass resulting from the biological wastewater treatment.

  #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

  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
