What Is Sludge Dewatering & How It Helps In Sludge Handling

-

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


Tannery waste water is considered as one of the most pollution sources. It can leads to the 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, the secondary Sludge occurs due to the activated waste biomass resulting from the biological wastewater treatment.



Treatment and disposal of the sewage sludge is the major problem the significant issues. Krofta engineering manufacturer various kinds of the sewage treatment plant to removes the mud from the wastewater treatment plant. The choice of sludge treatment mainly depends upon several factors such as volume, size, and disposal option.

Sludge Dewatering and Its Importance In Sludge Handling?

In sludge dewatering, the separation of liquid and solids phase takes place. The best use of sludge dewatering can be seen in the municipal or industrial wastewater treatment plant. Various techniques are used in the de watering of sludge, including plate & frame and belt filter process, geo membranes, and centrifuging.

It is essential to mention that de watering is not directly involved in sludge treatment because it only separates the liquid and solids components. But it plays a vital role in sludge handling and treatment because once the separation takes place, the contamination present in solid and liquid are treated separately.



Sludge dewatering is mainly used to reduce the weight and volume of the sludge, so the disposal and sludge handling can be done quickly and at the lowest cost. Removal of water is the primary factor in volume reduction. With the increasing water pollution, sludge treatment becomes one of the crucial factors for getting clean water.

  #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

  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...
