Water efficient filter size according to the content, according to different uses can choose A3 steel or stainless steel or glass steel, according to the water quality and water quality requirements, can choose single filter, double-layer or multi-layer filter material.
The water filter is to use one or several filter media, under a certain pressure, so liquid removal of impurities through the media, so as to achieve the purpose of filtering. The packing is generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc., the user can choose according to the actual situation.
1 the equipment cost is low, the operation cost is low, the management is simple.
2 filter after backwashing filter can be used repeatedly, long service life
3 filtering effect is good, the area is small
Application range:
High efficiency filter is widely used in water treatment process, mainly used for water treatment in addition to turbidity, reverse osmosis, as well as ion exchange to soften the pre-treatment of salt system, can also be used for surface water, groundwater in addition to sediment. Water turbidity requirements less than 20 degrees, the effluent turbidity of up to 3 degrees.
High efficiency filter
Superfine glass fiber as the filter material, with high filtration effect, low resistance, large dust capacity. Filters are widely used in optical electronics, bio pharmaceuticals, precision instruments. Mainly used in the clean room at both ends, can achieve a high purification effect 99.99%, with antibacterial effect, prevent bacteria into clean workshop, affordable, to meet the different requirements of the purification space.
Principle of type selection:
1, import and export Path: in principle, the import and export of the filter should not be less than the pump inlet diameter, generally consistent with the import pipeline diameter.
2, nominal pressure: according to the maximum pressure of the filter pipeline may appear to determine the pressure rating of the filter.
3, the choice of mesh hole: the need to intercept the main impurities in size, depending on the media process requirements. Screen size of various sizes of screen to check the size of the table "filter"".
4, filter material: the material of the filter is generally chosen to be the same as the process pipe material, for different service conditions can be considered to select cast iron, carbon steel, low alloy steel or stainless steel filter material.
5, the filter resistance loss calculation: water filter, in the general calculation of the flow rate, the pressure loss of 0.52 ~ 1.2kpa
Matters needing attention during operation:
(1), the system for a long time after shutdown, restart, the filter material for about 5 minutes of being washed, rinse to the clear water.
(2) system, the initial operation or long-term outage after operation, with equipment exhaust: open the exhaust valve, inlet valve, inlet and exhaust valve, until V8 discharge did not air until the (part of the small filter does not separate exhaust valve and exhaust outlet are available).
(3) for large filters, air can be used to scrub, to enhance the anti flushing effect, generally through the compressed air (strength 18 - 10 l/s.m2), and then the gas water back flushing.
(4) equipment, backwashing should control the backwashing intensity, should avoid activated carbon flushing leaking system.
(5) according to the situation of the water quality, the activated carbon filter material should be replaced regularly, and the general 6 - 3 months should be replaced once.
