Product Description

CONTINOUS RAPID SAND FILTER

It integrates flocculation, clarification, filtration and biological treatment functions, simplifying the traditional process flow;



The requirements for influent water quality are loose, and can withstand influent water with SS concentration ≤ 150mg/l;


Continuous filtration, high efficiency, no need for shutdown and backwash, no problem of primary filtrate;



Double sand washing, double cleaning effect;



The conical design at the top of the water distributor allows quicksand to have no dead angle.

PRODUCT BRIEFING

EVU'S continuous quicksand filtration system is a continuous operation treatment equipment integrating flocculation, clarification, filtration and biological treatment functions. It is widely used in the fields of drinking water, industrial water, advanced sewage treatment and reclaimed water reuse. The continuous flow sand filtration system (also known as activated sand filter) adopts the up-flow flowing bed filtration principle and a single homogeneous filter material. The filtration and sand washing are carried out at the same time. It can operate continuously and automatically for 24 hours without shutdown and backwashing. The ingenious sand lifting and sand washing structure replaces the traditional high-power backwashing system, which has low energy consumption, no maintenance, simple management and can be unattended.

APPLICATION

Advanced treatment of municipal sewage



Industrial wastewater treatment



Water Reuse

FUNCTION

WORKING PRINCIPLE

1. The water to be treated flows into the inlet distribution pipe at the bottom of the equipment, flows upward through the filter bed and is filtered, and then flows out from the filtrate outlet at the top.

2. The filter sand containing the treatment impurities is lifted from the conical bottom of the equipment to the sand cleaner at the top.

3. The cleaning of sand has started in the pump, and impurities are separated from the sand particles under the action of turbulent mixing. Dirty sand overflows from the outlet of the pump and enters the meander path of the cleaner, where the sand is washed by small flow of clean water in the reverse flow, and impurities are discharged through the outlet of the sand washing water, while the cleaned sand particles (heavier) return to the sand bed .

4. The result is that the sand bed continues to sink slowly in the equipment. Compressed air for the pump is supplied through the control panel.

Water purification and sand cleaning are carried out at the same time, so the filter can be carried out continuously without interference.

PRODUCT FEATURES

The influent water quality shall be loose and can withstand influent water with SS concentration ≤ 150mg/l;

It covers a small area and integrates flocculation, sedimentation and filtration, simplifying the traditional process;

The one-time investment is low, and there is no need to set up separate coagulation tank, clarification tank and other facilities, and there is no need for backwash pump, blower, electric, pneumatic valve and other equipment;

High efficiency, continuous filtration, no need to shut down and backwash, no problem of primary filtrate;

Deep filtration, the filter bed depth is 2000 mm, the filtration effect is good, and the effluent quality is stable;

The total head loss of the system is 1.2m, which greatly reduces the energy consumption for lifting;

It is easy to rebuild and expand, and the modular structure can flexibly increase or decrease the number of filters according to the change of water volume;

Excellent nitrogen and phosphorus removal effect can be achieved by using special biological filter material and adding carbon source and chemical agent
