Introduction
Shallow sand filters are most efficient for the filtration of water heavily contaminated with algae,
organic matter and other impurities, such as in open reservoirs and recycled water systems.
Shallow sand filters consist of one or more filtration units. Water enters the filter via the inlet
located on top of tank and spreads evenly on the media. Dirt particles and organic materials are
trapped on the media surface. The clean water percolates through the media and flows out via the
outlet located on bottom of tank. The cleaning backwash process is done by shutting the inlet of the
filter and allowing water to enter from the bottom, lifting the media and releasing the dirt particles
through the top drain pipe. This process can be controlled automatically.
Features
1. High filtration speed and low pressure loss.
2. Modular setting, small footprint, less piping, and low investment.
3. Manual, semi-automatic and fully-automatic backwash options are available to fully meet your
needs.
4. The backwash water source can be selected from the internal system, water tower or external water
source.
5. Multiple units can be combined, and the processing flow can be expanded arbitrarily.
6. The shell and pipes are made of carbon steel or stainless steel.
7. The core components are imported original (BERMAD, BACCARA, SIEMEN, MITSUBISHI).
8. The filter unit adopts a single-chamber design, which has better backwashing effect and lower sand
runoff rate.
9. The water collector can be made of stainless steel/ABS and has a longer life.
10. The water outlet pipe is set at the bottom of the unit, with smaller water resistance and easier
maintenance.
