Leather wastewater
The production of leather goods, leather goods, leather
sheets, and wool produces a wide range of products, composite waste, high
amounts of wastewater containing in contrast to most impurities and emissions.
The uncontrolled issue of wastewater runoff from natural cans increases the
health risks of citizens and pollution. Materials used from new skin care
products, which produce wet greens, skin coverings, or finished skin contain
trivalent chromium mixtures and sulphides in many cases. Biological and other
materials are responsible for higher BOD and COD values and represent a greater burden of pollution,
resulting in technological problems, sophisticated equipment, and higher costs
associated with pollution treatment.
Provides a summary of water supply for each of the
distribution activities during the dry season. Calculating the type of
technology used (standard or advanced) water use varies greatly. The deliberate
technology will be expanded in comparison with conventional methods including
procedures commonly referred to as small waste disposal technology or cleaning
technology. Especially in arid regions, where the water system is limited, this
factor plays a very important role. Disassembly, Blowing 7-11 2.0 Heating 3-5

Wastewater treatment The lubricant industry is one of the oldest industries in
the world and therefore the problem with the treatment and disposal of such
waste is probably old because of the industry itself.
. There are cases where the genital skin uses all the
contaminated water treatment measures described below on site. In some cases
genital skin can only be used (on-site) for pre-surgical treatment or
pre-initiation treatment in the neighborhood or there is no minimal treatment,
which sends the contamination to the central contamination treatment facility.
However, treatment is important due to the wide selection of toxic substances
in the environment caused by untreated skin debris.
The following treatment steps are necessary and can be
described in detail afterwards:
• Mechanical treatment
• Dirty treatment
• Post-cleaning, water column and sewage management
