Media Filtration System

Quartz Sand Carbon Filter Sand Filter Auto Multimedia Filtration System Sand Filter Tank

Equipment Introduction

Medium filter is a kind of filter medium to remove the suspended matter in the water, Quartz sand filtration is one of the more effective means to remove suspended solids in water, is an important unit in the depth of sewage treatment, sewage reuse and water supply treatment, its role is to further remove the water has flocculated pollutants, it through the filter media interception, sedimentation and adsorption, to achieve the purpose of water purification. When the water contains suspended matter and mechanical impurities, adhesive glue particles that can not be removed by precipitation and other methods, the water can be passed through the filter layer installed in the pressure filter to make the water clear and transparent.

Working principle

The integrated water purification unit has the same purification process as the urban water supply plant. It has: coagulation tank, sedimentation tank, filter tank, water quality stabilization device, backwashing device, water pump and electrical control cabinet. The following are respectively introduced:

1. Coagulation pool: the raw water added with coagulant enters the coagulation pool from the inlet pipe and is stirred by a special mixer to make the suspended matter in the water fully contact and react with coagulant to form alum. General water purification devices use eddy current reaction to mix water and coagulant, but the effect is subject to changes in the amount of water and unstable. The water purification device is mixed with a mixer, and the effect is not affected by the change of water quantity.

2. Precipitation chamber: alum is formed after water is coagulated with coagulant, which flows to the sedimentation tank of the equipment for precipitation. Inclined pipe sedimentation method is adopted in the sedimentation tank, and solid and liquid separation is completed through trapezoidal inclined plate sedimentation chamber, and the settled sludge is discharged into the mud bucket.

3. filter tank: after the precipitation of the water flow to the filter tank filtration, filter structure: the bottom of the water pipe, the middle of the quartz sand, the upper part of the anthracite. The filtration rate is 10m/h, and finally the water is washed into the clean water tank for disinfection and drinking. The filter tank recoil cycle is about 12 hours, and the recoil time is 5-10 minutes.
