Waste Water Treatment
Surface treatment equipment inevitably discharges industrial waste water into rivers or sewers during operation, so that the emission requirements are increasingly stringent. For this reason, the company Steuler, Germany has developed a "zero waste water" process, which is achieved by recycling water
and chemicals and reusing it.
With regard to Zero Liquid Discharge (ZLD), the core concept of Steuler is to combine effective energy
use with the economic recovery of water and raw materials to reduce environmental pollution.
The waste acid, waste solution and rinsing water generated during the operation of equipment are gradually concentrated by evaporation or condensation, and finally only the condensate, water, con-
centrated acid and metal salt solution remain.The condensate is recycled as new water to the surface treatment of the material. It is obvious that separating acid and metal from the hydrochloric acid solu-
tion is an economically viable method.The separated acid and metal can be reused,and other residues
are made into dry mud cake and buried.
With our partner, Steuler Germany, we will communicate with our customers closely to design and de-
velop economical, resource-saving and environmentally friendly processes for the treatment of spent
acids, waste solutions and waste water, and to provide relevant equipment to meet customer needs
as well as the requirements for the future. When formulating a plan, it is important to consider the
costs of chemicals and water supply, waste water and residue treatment and recycling, and energy
