Product introduction
The top mount sand filter? is a kind of pressure filters, widely used in water treatment industry. Winding cylinder body generally for glass fiber reinforced material, stainless steel sand filter cylinder, otherwise the plastic tank glass sand cylinder, the glass fiber resin types are common. Glass fiber and resin sand cylinder was called sand filter cylinder, sand filter tank, etc. Its high intensity, long service life，Resistance to acid and alkaline liquid, uv resistance, ageing resistance. Suitable for outdoor project. Unique design of the water distribution device can uniformly stable flow of water, drainage culvert with high efficiency. Easy to install, repair, maintenance is convenient. Small flow sand filter cylinder is generally equipped with multi-purpose valve, can be convenient to wash backwash operations.
Top mount sand filter multifunctional valve:
1. FILTER: normal FILTER and clean water.
2. BACKWASH : discharge filter of inner product contamination.
3. RINSE : out of the contamination of sewage pipe.
4. RECIPCULATE : without filter water circulation.
5. WASTE : without filter, sewage directly.
6. CLOSED : will shut inside the filter function.
Working principle of FRP sand filter:
After filtering the sand filter, water quality changes:
Description:
1. When first run, should filter operation water head to rinse position.
2. When use, general connection in front a pressurized water pump.
Filter material selection
If it is to remove the solid in suspension in the water impurities, can choose quartz sand as filter medium. If it is to the water absorption of some chemicals, can choose activated carbon, become activated carbon filter sand cylinder cylinder at this time. Additional ejection type sand filter cylinder can also be used as a biological filter.
The product application
Because of its high strength, convenient transportation, simple installation and low price, the filter sand cylinder has been widely used in seawater factory culture, swimming pool engineering and drinking water treatment.
In the background equipment room of water treatment engineering:
Commonly used filter sand filter for water filtration in swimming pool:
Water treatment in Marine aquarium:
In aquaculture water treatment, it is generally used to filter raw water instead of traditional sand filter ponds:
The koi pond also USES a top out filter cylinder to filter impurities in the water to ensure the water is clear:
