Shallow Filter is an innovative, sand thickness of only 40 mm, the spherical shell and unique interior design to ensure smooth flow filter, filter effects form the inner turbulence; Backwash backwash efficiency is high, time is short, backwash consumptionthe amount of water is about 30% of the traditional sand filters. Changed the traditional sand filters, valveless backwash waste water, backwash incomplete, bulky, rookie of the media filter industry.
Product Features:
Shallow filter filtration system uses a modular design, based on traffic, covering, etc., can be flexibly combined. The system can be used, pressure a variety of ways to start automatically backwash, fully automatic operation. Each filter unit in the system sequentially backwashing is not interrupted when the backwash effluent.
Automatic control of the filtration system is modular in design, according to the size of the flow, a plurality of filter units.
Can be used, pressure, etc. A variety of ways to start automatically backwash the filter unit in the system are backwashed, the other unit is still in the filter.
The high recoil efficiency, recoil a short time, the backwash water conservation (backwash water consumption rate is less than 1%).
Small footprint, and the flexibility to design the arrangement of the filter unit according to the actual land.
The system is lightweight and does not require special base concrete floor can.
All-plastic system, good corrosion resistance.
ASM filter, has a better resistance to bacterial contamination, the backwash better.
Shallow filters system is lightweight and does not require an ad hoc basis, a general concrete floor system covers an area of small, flexible arrangement according to the actual situation, easy to install.
The shallow filter filtration system can be applied to a variety of water treatment industry, such as water supply and filtration treatment, cooling circulating water filter and next to the filter, wastewater treatment and reuse, and so on, is an alternative to traditional sand filters, valveless preferred.
