Product features:

● BOWNT BOM is designed with removable end covers on the top and bottom of the filter. The bottom one is used for installing and adjusting the water collectors and emptying and maintaining filter materials. The top one is used for adding filter material and checking the internal filtering situation. Leakage-proof design of end covers is based on the principle of water sealing, which is more safe and reliable.
● Special design of umbrella-shaped pressure compensation water collectors ensures a pressure balance for all parts during filtration, high flow velocity and efficiency; inner loop during the backwashing cycle attributes to a good backwash effect and lower water consumption.
● Feed water can be uniformly distributed to the cavity through the filter diffuser even under high flow velocity, greatly improved of filtration effect.
● Filter housing is made of sturdy steel, precision welding with internal&external anti-corrosive painting(rubber liner or plastic coating), pressure up to 145psi(1Mpa).

Working principle

BOWNT BOM filter consists of several filter units; feed flow enters the filter units for filtration through the three-way valves ( connect the feed line to the filter units and close the drain line ), produced water after filtration converges into the discharge line. Water fills into the internal filter media smoothly through the diffuser, then impurities intercepted. Several of umbrella-shaped water collectors at the bottom of the filter uniformly collect and discharge the filtered water.BOWNT BOM filter adopts advection filtration, which realizes a better filtration effect at high flow velocity.
While filter head loss is increasing due to the accumulation of impurities in the filler media surface,filter automatically switches into backwashing cycle to clean up the impurities. The control unit sends a signal to the solenoid valve of the first filter unit, and the solenoid valve is activated under the water pressure to cut off the feed line and connect the filter unit to the drain line. At this point,filtered water back flushes the filter media in a high speed under the back pressure, then the waste water is discharged from the drain line. Special designed water collectors form a inner loop in the filter media during backwashing, filter media rubs against each other to maximumly increase the backwashing frequency and reduces water consumption, without sand leakage during backwashing.Once finished the backwashing cycle, valve returns to the filtering status, and next filter unit goes on with backwashing cycle.
