carbon steel dosing system backwash water treatment plant

Integrated fully automatic water purification equipment can produce water purification equipment of different materials such as stainless steel and carbon steel according to user needs.

The integrated fully automatic water purification equipment adopts physical filtration methods, integrating coagulation sedimentation, aeration, dissolved oxygen, multi-layer filtration, automatic backwashing, automatic sewage discharge, automatic control and other process technologies, effectively removing suspended solids, sediment, algae, organic matter, carbon dioxide, iron and manganese ions, etc. in water. The equipment's water purification process does not require manual intervention, and the operation and maintenance are simple and convenient. Suitable for various types of water plants, surface water treatment, rural domestic water, river water drinking purification, etc

Integrated fully automatic water purification equipment purification process

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.
