Shallow Medium Sand Filter for Living Water Filtration
Instruction of Shallow Medium Filter
Shallow Medium Filter (also with name of FQGsystem) is a kind of highefficiency filterequipment in cutting down water turbidity, and purifying water.
It uses silica sand asits filter medium. Under a certain pressure,
the muddy water come through the granular or nongranular silica sand,
which can efficiently hold back suspended solids, organisms, colloidal solids, micro-lives,
chlorine, odour and heavy metal ions, etc.
It consists of several standard filter tank unit, with unique water distributor and water collector inside.
Theboth way automatic backwash valve can control all system's backwash process.
Shallow Medium Filter is mainly used in pretreatment in water turbidity removal, water softening, electrodialysis,electrodialysis reversal.
However, it makes function on surface water, under ground water as well. Shallow Medium Filter can also be widelyused in fields of electronic power,
petrochemical,metallurgy,electroplating, papermaking, textile, pharmacy,
soft drinks, living water, industrial water, swimming pool, etc.
Shallow media filter can widely used at different application, such as water filtering, cooling water by-pass filtering, waster water treating, etc.
1. Shallow media filter has flexible modules, which can combined under actual flow rate, on-site area.
It is operated backwash automatically, with time control, differential pressure control. Each filter element
start backwash one by one, while no need stop operation in backwash.
2. With smooth water allocation. High efficiency in backwash, water saving, only 30% water consumption of
traditional one. Filter uses ASM filter media, which is easy wash.
3. With unique 48" ball filtering unit, and light weight for the whole system. The normal concrete base can used
to place. Easy install, no need any boom equipment.
4. With good anti-corrosion feature.
5. With lost cost, but long lifetime.
6. Water quality: inlet water turbidity <80mg/L, outlet quality reach <20mg/L
inlet water turbidity <20mg/L, outlet quality reach <5mg/L
7. Flow rate: it can treat 30-500m³/h
Filter structure: main part includes filter tank, water distributor, water collector, hand hole and support
Filter tank: it gives enough space for water distributor and collector. Each water collector has 55 water
caps, which reforms a internal recycle flow when backwash, no sand leak.
Water distributor: it makes sure water flow smoothly on the padding sand media.
water collector: with 55 unique mushroom shape water caps makes sure water pressure in a balance.
It can reforms a internal recycle flow when back wash, no sand leak.
Hand hole: There have a up and down hand holes, which is easy for installing and replacing water
distributor and collector. Meanwhile, the upper hand hole, which is easy for inspecting and adding silica.
And down hand hole, which is easy for clear and repair.
Support base: it is assemble, it can adjust in according to on-site situation.
The head loss increases as the impurities accumulates at packing layer continuously. When it comes into
a limitor reached to time limit, system will switched into backwashing to clean packing layer's impurities.
To clean these accumulated impurities is a must thing.
In the process of backwash, the on-off switch of three-way valve will be changed by PLC, with inlet closed,
and drain let open. Impurities will out through three-way vale's drain outlet.
On FQG system, a circulation exists at packing layer under the function of the specialized collector. Silica
sand rub each other, which high efficiently improves the backwash. When backwash is finished, valve returns
to filteringstate, which another filtering comes into backwash.Normally a filter system is made of multi-filter tank,
they work in turn, which ensure there's no stop in backwash
