Does the water treatment filter equipment need backwashing? Generally, fine filtration such as 0.22 1 5 microns will be destroyed by positive backwashing. however, if you want to rinse, rinse with pure water below 0.4MP, and rinse with pure water below 0.2MP. the filter element in the precision filter is often used with polypropylene hot spray fiber membrane and nylon, precision filter pieces made of filter media such as PTFE micro-pore filter membrane. The filtration accuracy can reach 0.1um, and the filtration pores are irregular, especially the polypropylene hot spray fiber membrane, which is formed by the dissolution of the PP material, the normal filter direction is to penetrate the filter from the outer surface of the filter element to the inner surface. The backwashing process is to wash the water from the inner surface of the filter element to the outer surface. the backwashing process cannot rinse the fine particles and activated carbon powder attached to it, it is necessary to reverse wash the pump

The reason why the turbidity of carbon filter water is larger than that of sand filter water The landlord needs to backflush the sand filter immediately,And use compressed air,Carry out air-water washing,Artificial sand is required if necessary.First,The dirt in the pipe will be rushed out twoSince the flocculation treatment is carried out under alkaline conditions,Quartz sand will be corroded under alkaline conditions,After a long time, naturally,Therefore, the sand layer needs to be re-dispersed.
