Bypass filter for circulating water

Product introduction

The circulating water bypass filter does not install the circulating water bypass filter on the main circulation pipeline to filter all the circulating water, but leads out a part of the circulating water to filter on the main circulating pipeline. The circulating water bypass filter is The impurities in the system are filtered through repeated cycles of interception, and the impurities are filtered out of the water circulation system through backwashing.

Working principle

Filter status:

The shallow filter is composed of several filter units in parallel. When the system is in the filtering state, the unfiltered water is evenly distributed through the self-developed water distributor, and the water passes through the packing layer (refined uniform-grained quartz sand) in the filter in a laminar flow state. When water flows through the packing layer, impurities are trapped in the packing layer. There are a plurality of evenly distributed water collectors at the bottom of the filter, the filtered water is evenly collected and drawn out, and the advective filtration can make the filter filter at a high flow rate, and still achieve a better filtration effect.

Backwash status:

As impurities accumulate in the packing layer, the internal head loss will continue to increase. When the head loss of the inlet and outlet water reaches the set value, the system will switch to the backwashing state. When the backwashing of this station is completed, the hydraulic valve changes the direction of the water supply to realize the backwashing one by one, which is convenient for cleaning the accumulated impurities.

Product advantages

1. High filtration speed and low pressure loss, to solve the problem of slow filtration speed and small flow of ordinary mechanical media filters.

2. Modular setting, small footprint, less piping, and low investment.

3. Manual, semi-automatic and fully automatic backwashing is optional.

4. The backwash water source can be selected from the system, water tower or external water source, and can be automatically switched.

5. It can be combined with multiple units, and the processing flow can be adjusted as needed.

6. The shell and pipes are made of carbon steel Q235B or stainless steel.

7. The filter unit adopts a single-chamber design, with good backwashing effect and low sand running rate.

8. The water collector can be made of stainless steel/ABS material with long service life.

9. The water outlet pipe is set at the bottom of the unit, the water resistance is smaller, and the maintenance is more convenient.
