Wastewater Treatment

The wastewater has many different types, the composition of each wastewater varies greatly, and the wastewater discharge situation of each enterprise is different. Therefore, in general, customized wastewater treatment solutions are required according to the actual situation to ensure the efficient and stable operation of wastewater treatment. Here, taking chemical wastewater as an example, the typical wastewater treatment technology is introduced.

The main methods of chemical wastewater treatment in Alfa Chemistry include pretreatment technology, anaerobic biological treatment technology, aerobic biological treatment and advanced treatment reuse technology.

• The pretreatment technology uses physical or chemical methods to remove the water-insoluble colloid, oil and suspended solids and other pollutants in the wastewater. At the same time, chemical REDOX technology is used to reduce the concentration of COD and the pollutants containing biological toxicity.
• Anaerobic biological treatment technology is the use of high efficiency anaerobic complex reaction to remove most of the COD organic pollutants in wastewater. Usually, wastewater can be directly discharged after anaerobic process.
• Aerobic biological treatment uses efficient and stable biofilm treatment technology, MBR membrane biological treatment technology, fluidized bed, traditional activated sludge method and other technology for further treatment of wastewater, making the improved quality of effluent.
• For chemical enterprises with strict requirements, the advanced treatment technology of chemical wastewater from Alfa Chemistry can be adopted. The technology will deeply treat the wastewater and then the wastewater can be used in production or landscaping, so as to achieve zero discharge of chemical wastewater.
