Shallow Sand Filter

The Shallow Sand Filter is composed of one or more standard high-speed filter units. The water flows through the internal water distributor and water collector, using different media, which can effectively remove particles and reduce turbidity. If it is equipped with specific fast materials, it can also adsorb and remove the organic matter, ions, etc. of the corresponding sand speed layer.

FEATURE

When the system is in the filtering state, pressurized water flows into the water distribution system from the inlet of the filter unit and reaches the filter material layer evenly. When water flows through the filter material layer, the suspended matter is intercepted by the filter material. There is a water collector with a precision gap at the bottom of the filter, and the clean water after filtration is evenly collected and flows out of the filter. As impurities accumulate in the filter layer, the pressure loss continues to increase. When the pressure difference increases to a certain set value or reaches the set cleaning time, the system will automatically switch to the backwash state. The pressurized water enters the filter material layer through the water collecting device, and flushes it, so that the trapped pollutants fall off and drain out of the filter system. After backwashing lasts for at least 2 minutes, the valve automatically switches the system to the filtering state.

APPLICATION AND FEATURES

A nozzle for industrial process water filtration, water protection filtration for heat exchange stations
Industrial circulating water filtration-industries such as iron and steel, metallurgy, papermaking, heat exchangers, electric power, petrochemicals, food, air-conditioning systems, etc
Raw water treatment system-surface water, river water, river water, lake water, sea water, etc
Irrigation filtration—Water filtration for farmland, parks, municipalities and golf courses
Water filtration in aquaculture, swimming pools and water parks and other industries

High filtration speed, low pressure loss, completely solve the problem of slow filtration speed and small flow of ordinary mechanical media filters
Modular setting, small floor space, less piping, and low investment. The floor space is reduced by more than 40%, and the amount of piping works is reduced by more than 50%
Manual, semi-automatic and fully automatic backwashing are optional to fully meet your needs
The backwash water source can be selected from the system, water tower or external water source, and can be automatically switched (on special requirements)
16"- -96" units of various models can be selected, multiple units can be combined, and the processing flow can be arbitrarily expanded

Product advantages:
1. The core components are imported from original packaging.
2. The over-speed element adopts a single gun design, which has better backwashing effect and lower sand running rate. 3. The water collector can be made of stainless steel/ABS, which has a longer life.
