SQ type auto mechanical filter
Brief Introduction:
SQ filter belongs to no electricity control, no valves, no special operator, with no auto backwash system and water tower model. When increasing the suspend material of upper filter media, the filtering water flow speed reduce gradually and the tank body water level increased accordingly till fixed rated height (negative pressure), it becomes siphon (absorption), a few minutes later, the water stream will soon change flow direction together with water from high level water tank from bottom into upper, when the water in high level water tank reduces max. Lower position to break the air incoming of the hopper then stop siphon, the water flow soon back to original flow direction.
The device has no default with high water-saving, electricity-saving, human-saving function; it can be applied in matching automation project.   
Applied Range:
SQ model filter main applied in removing solid grain suspend impurities
In water, as well as those filtration which can form absorption and
Settlement below:
1. Tap water purification filters for downtown, village, waterworks, industrial and mining enterprises field.
2. As a bypass filter of circulated water production for petroleum, chemical, metallurgy, electric power, textile, medicine, light industry, machinery fields.
3. As water purifying device of water scenery and swimming pool of advanced hotel, Villas, restaurants, commercial buildings.
4. as a softened water for boiler feed water unit and the electric power industry.
5. as a water treatment device for food, industrial and beverage industry.
6. as a recycled water purifier for water output from w wastewater treatment process.
 
Technique Function
It in non e-control filters by running upon water gravity pressure and mechanical principle. It can be divided into gravity style and pressure style. Below is main for gravity style, if want to pressure style, we will special design and provide solution for you
1．Save raw material to produce water utilization ratio over 97%.
2．No backwash device with lower running water nozzle (0.06MPa) save electricity over 20％.
3．Simple structure, small footprint, save pipeline, civil engineering, and auxiliary facilitate, and mounting charge.
4．Body use CS , main parts use S.S. and cooper.
5．Output water quality between 0．5 and 10NTU (adjustable )
6. Technical function

Mounting and Maintenance:
1. It can be running by connect inlet, outlet and discharge pot pipe.
2. Installation Requirements vertical deviation ≤ ± 1.0mm.
3. Must install a pressure gauge on the water pipe (0-0.6MPa).
4. This water filter need add filter media every 6 months, first stop water coming  and drain it clean , then open man hole to add filter media into design height , each year do a haul: follow first step to drain  out water , open the man hole to take used filter media out , then the operator can enter into the filter to check and maintain it  by checking balance tank flexible working or not , if needing replace  rusted parts  and filter cover , let jammed filter cover go through  and add filter media into design height.
