I. Overview
With the rapid development of industrial and agricultural production, the water supply in many areas is increasingly insufficient, while the water bodies are polluted, and the water quality of some water sources is deteriorating. Water is a precious resource in nature and an indispensable material for industrial and agricultural production and people's life. Water-saving work is becoming more and more important, and the renovation project for wastewater reuse is gradually increasing. However, in some factories and mines or wastewater treatment stations, the anti-washing of filtration equipment is not complete, the floor space is too large, and the high water consumption limits the progress of water treatment work.
In view of the wide application of filtration equipment and the current actual engineering conditions, there is an urgent need for a filtration equipment with high precision, high filtration speed, thorough backwashing and low water consumption.
PCF pore-regulating fiber filter has the characteristics of high precision, high filtration speed, thorough backwashing and low water consumption.
Second, the principle of PCF filter
During the filtration process, the filaments are pressed by the rotary machine so that the pores in the longitudinal direction of the filaments become smaller, the suspended solids in the water are blocked and left outside the filaments, and the cleaned treated water is obtained after filtration. When the suspended dirt (impurities) trapped in the filter increases, the amount of treated water drops, and when the pressure reaches the set value, it automatically enters the backwashing process.
During the backwashing, the filter press is relaxed, so that the pores of the filter fiber are in a relaxed state, backwashed with compressed air and treated water, the dirt is removed through the discharge pipe, and then automatically enters the filtration process to achieve decontamination. The principle of clearing.
