High speed Bypass carbon steel water sand filter
By-pass filter for chilled water as a by-pass filtering equipment of closed industrial circulating water is used
to filter the circulating chilled water
and its control modes consist of manual backwash and automatic backwash. The system is generally
backwashed once every three to seven days in the circulating process, effectively improving the quality of
chilled water and ensuring excellent and stable water quality after intervention to long-term running. The
device has small water consumption and is widely used in the cleaning of all types of
industrial and commercial chilled water circulation system as well as refrigerant water and heat medium
water systems of central air conditioning, improving the stability of equipment operation. Users may weld
and conned in parallel the by-pass filters in main return pipes depending on the conditions of circulation
system and the pipe diameter
should be determined based on the retaining water yield of parallel circulating water. The sewage water is
then discharged into the sewerage network.

How it works( Shallow medium filter):
Flushing filter state:
When the system is filtered state, the unfiltered water through self-developed unique water distributor uniform water distribution, water through the filter to laminar flow conditions within the filler layer (refined grains are quartz sand / garnet). When water flows over the packing layer, impurities are trapped in the filler layer. Bottom of the filter with multiple evenly distributed catchment, the filtered water and leads to uniformly collect, advection filter, the filter can filter at high flow rates, can achieve better filtering results
Backwashing state:
With the impurities accumulate in the filler layer continuously, the internal pressure head losses will continue to grow. When the inlet, the pressure head loss reaches the set value, the system will automatically activate the constant pressure device to switch to backwash the state, when the end of this table backwash, water valve to change direction in order to achieve one by one water backwash, cleaning easier accumulate up impurities.
When the system is in state anti-washing, filtering continues, which should be the standard unit backwash sand filter tank is not, the system of other standard sand tank still in the filter unit. Filtered clean water part of the standard unit used to backwash the sand tank, the rest are still sent to the user Department. Backwash water through the backwash outlet water valve has been discharged. Sand-cylinder high-speed automatic and efficient filtration system, the special design enables the catchment between the filler filler scrub each other to maximize the efficiency of backwashing, the backwash water to reduce the required (clean water), and when the backwash phenomenon is not expected to run. A standard unit of sand backwash tank is 2 minutes, the end of the backwash, the standard unit of sand-cylinder internal pressure head loss is reduced to a reasonable range, given the constant pressure device recovery signal, filtered water valve back to the state, under a standard sand-cylinder unit backwashing is ready to enter the state.
Shallow medium filter Equipment installation instructions:
1. The connection for equipment inlet/outlet water pipe and drainage pipe with system is standard flange connection.
2. Pre-installed pressure gauge on inlet and outlet pipe;Drainage pipes increased regulation valves and observation tube.
3. Pre-installed manual valve on inlet and outlet pipe, to ensure that the sewage smooth;
4. Equipment installation at 200mm high cement platform without the basis of embedded, need 220V50Hz power outlet (power controller) nearby.
