Every leather industry produces a huge quantity of leather wastewater which is called tannery wastewater that has an enormous number of pollutants that damage the environment if it is discharged without the right treatment. The tanning processes of the leather wastewater are responsible for the discharge of uncontrolled chlorides, sulfates, and other heavy metals that pollutes water. A large quantity of water is used in the tanning process of which 90% of the water is discharged as effluent. There are 4 stages to treat leather wastewater:

• -Preliminary Stage (Screening, Grit removal, Oil & Grease Removal0)
• Primary Stage (Equalization, Neutralization & Sedimentation)
• Secondary Stage (Aerobic Process & Anaerobic Process)
• Tertiary Stage (Sand Filters, Carbon Filters, Micro Filters, Ultra Filtration, Retention Ponds, Nano Filtration & Reverse Osmosis).
If the leather wastewater is left into the water bodies untreated, the following would be the consequences:
• Cause blue-tinted water poisoned with chromium, lead, and arsenic.
• Decades of contamination in the air, water, and soil
• People suffering from asthma, eyesight problems, and skin diseases, liver & kidney problems.

  #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
