Biofilter system in leather industry
Leather industries have high water consumption so they release enormous wastewater in environment, and usually have high amount of BOD, COD, TDS, sulfide, ammonium, nitrate and heavy metals such as chrome, industrial salts, organic compounds and skin waste. In case that this waste enters into the environment without treatment, it causes severe damage to the environment. PGA biofiltration, using a combination system physical, chemical and biological methods based on biofilter is capable of purifying of sewage of leather industry up to the standards of the Environmental Protection Organization and can be used again.
