Municipal river civil structured water treatment plant

A municipal river civil structured water treatment plant is a facility designed to treat water from a nearby river for municipal use. This type of plant typically includes various treatment processes such as screening, sedimentation, filtration, and disinfection to remove impurities and contaminants from the water. The treated water is then distributed to the local community for drinking, industrial, and other uses. These plants are essential for ensuring the supply of clean and safe water for the public and are typically operated and maintained by the local government or water utility.

1. Coagulant dosage:

According to the turbidity of the raw water, use a dosing device to evenly mix the coagulant into the pipeline mixer.

2. Coagulation and sedimentation:

Suspended solids and colloidal particles in water generate coarse alum flowers for automatic precipitation, achieving solid-liquid separation, reducing the burden of filtration, and saving backwash water consumption.

3. Filtering:

The residual small alum flowers are intercepted by the filter layer, resulting in a turbidity of 0.4~1 NTU in the effluent;

The filter layer is composed of 4-7 different media filter media, which can trap solid particles in the filter layer and achieve a cleaning rate of over 98%.

4. Disinfection:

After being disinfected by an electrolytic sodium hypochlorite generator, it flows into a clean water tank.

5. Automatic backwashing:

The increase in the interception capacity of the filter layer causes the water level to rise. When the design requirements are met, a bottom-up backwash is carried out, and the filtration is automatically restored after the flushing is completed.The backwash water is provided by the filter water tank, with a backwash strength of 8-66l/s · m ²， The recoil takes 3-6 minutes.
