Most employing pressure type mechanical filter in the pretreatment system being water source with well water or running water; Mechanical filter is divided into small-sized, large-scale two classes;
Small-sized machine filter: generally have bi-material to make, one is steel vessel, operating pressure 6 kg/cm; Another kind is hard plastics, and operating pressure is 2 kg/cm, forms series by diameter 300-1000 millimeter;
Big machinery filter: be divided into single current and double-current method two kinds; Series is formed by diameter 1000-3000 millimeter;
More medium filter is a kind of pressure type rapid filter, can remove very little colloidal solid and suspension, uses water erosion degree and reaches about 1 degree;
Active carbon filter
The macroporous adsorbent, adsorbent charcoal etc. of active carbon filter many employings granular active carbon or Prof. Du Yucang; Be characterized in applied range, treatment effect is good, and floor space is little, reliable operation, convenient management, adsorbent can regenerate; Gravity or pressure type adsorption column can be made separately; Active carbon filter can remove Organic substance in water, colloidal particle, microorganism, Yu chlorine, stink etc.
7. the applicable Die & Mold Manufacturing Companies production material returned of new-type cloud computing system is reclaimed and is analyzed pretreatment system deferrization and demanganization device, and ferrum-manganese removing device series utilizes water and oxygen fully to contact and through the catalysis of manganese sand, by the iron in water, manganese is oxidized, formation colloidal precipitation
Laminated filter (also known as disc filter)
Accurate filtration: can require according to water the filtration lamination selecting different accuracy, have the plurality of specifications such as 20 μ, 55 μ, 100 μ, 130 μ, 200 μ, 400 μ;
Efficient backwash: at a high speed and backwash thoroughly, can complete about only needing 7-15 second, backwash water consumption is lower than filtering 0.5% of the water yield;
Fully automatic operation, continuous effluent: in filter set cover, backwash process one after the other is carried out, and automatically switch between work, backwash state, can guarantee continuous effluent, voltage loss is little;
Standard modular: standard modular system, user can configure as required, simple and flexible, and interchangeability is strong;
Save and take up an area: can space, flexible utilization corner, suit measures to local conditions to install, take up little room; As the process water yield of 300 cubes ms/h, general water quality, the equipment being filtered into grade 100 μ takes up an area only 3 square metres;
Reliable maintenance is simple: need regular maintenance hardly, installs easy to operate, and parts 100% detect and test running through factory, and do not need specific purpose tool, required standby redundancy is little
High-tech plastic filter core is firm, without wearing and tearing, corrosion-free, through industrial practical validation for many years, to filter and backwash effect can not be deteriorated with service time.
