With the large-scale production of antibiotics, people began to study the treatment of antibiotic wastewater. Water treatment experts have developed successful self-cleaning filters to effectively treat antibiotic wastewater. Secondly, at present, the more mature method for treating antibiotic wastewater at home and abroad is the activated sludge method.
Due to the enhanced pretreatment, the aeration method was improved, and the operation of the device was stabilized. By the 1970s, it has become a method commonly used by pharmaceutical factories in some industrialized countries. However, the disadvantage of the common activated sludge method is that the wastewater needs a large amount of dilution, and there are many foams in operation, sludge bulking is likely to occur, the amount of excess sludge is large, and the removal rate is not high, and it is often necessary to adopt secondary or multi-stage treatment.
The self-cleaning filter overcomes many shortcomings such as small dirt absorption, clogging of dirt, detachment and cleaning of the filter part, and failure to monitor the filter state, and has the functions of filtering the raw water and automatically cleaning and filtering the filter element automatically. Moreover, the system provides uninterrupted water supply when cleaning the sewage, and the working state of the filter can be monitored, and the degree of automation is high.
Self-cleaning filters cover a wide range of filtration accuracy requirements from 10um to 3000um, providing customers with a variety of water filtration equipment. Self-cleaning filter has small footprint, low investment, low operating cost, high efficiency, average removal rate of COD can reach more than 70%; strong resistance to water and organic load; no sludge expansion problem; good thermal insulation effect.www.inocofiltration.com
