Textile & Tannery
Wastewater treatment textile and tannery industry
Wastewater tannery industry
The manufacture of leather requires a lot of water not only for the production process, but also for the cleaning, de-hairing and soaking of the hides. Due to different additives that are added during production, the wastewater contains a high alkali content, chemical substances (chromium and sulfite) and organic substances. Therefore, it is not possible to dispose the wastewater directly to domestic sewage treatment plants.
Untreated wastewater which originates from tanneries contains extremely high levels of TSS, TDS, BOD, COD, sulfate, sodium and calcium. These values exceed the prescribed limitations and can create a potential threat to humans and the environment. It is critical that the wastewater from the production of skins be intensively treated before it can be discharged.
Wastewater textile industry
The textile industry is one of the most water intensive production industries in the world. Water is used throughout the manufacturing process and is critical for various flushing procedures. As result, high volumes of wastewater are generated that contain high organic pollutants, high sulphate concentrations, chemicals, toxins and color.
