Technical characteristics of slow-release disinfectant for drinking water in Lanzhou, Gansu Province

1、 Equipment features:

1、Combining traditional water purification processes such as coagulation, sedimentation, and filtration into one device, it takes up less space and is easy to install.

2、Automated and intelligent operation. It can be fully computer-controlled according to user needs, achieving comprehensive human-machine dialogue. In addition to managing the water pump and dosing system, the equipment automatically processes water intake, coagulation, sedimentation, filtration, effluent, backwashing, and sewage discharge without the need for manual operation.

3、Strong adaptability, stable and reliable effluent quality, sufficient water quantity. When the turbidity of the source water reaches 3000 mg/L, the effluent turbidity can be stabilized below 3 mg/L, meeting the standard for tap water turbidity

2、 Process flow:

Source water → booster pump → sand filter → carbon filter → precision filter → slow-release sterilizer → water tank

3、 Technical specifications:

Including raw water pump, quartz sand filter, activated carbon filter, and precision filter. Its main function is to remove particles, colloids, organic matter, chromaticity, residual chlorine, and bacteria from raw water.

1) Mechanical filter

Working principle: A mechanical filter is a pressure filter that uses refined quartz sand filter material filled in the filter. When the incoming water flows through the filter layer from top to bottom, suspended solids and adhesive paper particles in the water are removed, thereby reducing the turbidity of the water,

When the device runs for a certain period of time, it stops running for backwashing. Adopting water backwashing with a backwashing time of 15-20 minutes. Regular manual control.

The turbidity of the water produced by mechanical filters is generally below 2 degrees, and the SDI (Pollution Index) can generally be below 4 degrees.

2) Activated carbon filter

Working principle: The adsorption capacity of activated carbon is mainly based on physical adsorption, and it can also perform some selective adsorption, namely chemical adsorption. Activated carbon is a widely used adsorbent in water treatment. During the activation process, various shapes and sizes of voids are generated between the crystal lattice, resulting in a huge surface area. Therefore, the carbon water contact surface is large and the adsorption capacity is strong. Effectively ensuring the service life of subsequent equipment and improving the quality of effluent water. In the process of pure water production, the role of activated carbon is mainly manifested in four aspects: reducing the oxidation degree of water; Remove residual chlorine from water; Remove trihalides (THM) from water.

3) Precision filter

The precision filter is equipped with multiple polypropylene melt blown filter cartridges, which should be replaced when the pressure difference reaches 1kg/cm2. Under normal working conditions, the filter element can maintain a service life of 3 to 6 months or more, and the structure of the filter meets the requirements for quick replacement of the filter element.

4) Slow-release sterilizer

The slow-release sterilizer adopts a chemical reaction, automatic slow-release delayed pressure chlorination process, using strong chlorine solid agents with a content of over 90% as the main raw material. The disinfectant produced by reasonable mixing of water and agents is added to water tanks, wells, pipelines, and sewage tanks for sterilization.

4、 Quality assurance and after-sales service

To ensure the smooth progress of project design, equipment manufacturing, and system debugging, and provide excellent after-sales service, our company has taken the following measures:

1. Ensure quality, control the entire process of products and services, and actively provide pre-sales, in sales, and after-sales services.

2. Ensure the normal operation of the system, free maintenance during the one-year warranty period, and free repair or replacement of important components in case of quality problems during the warranty period;

3. Ensure long-term maintenance services and provide authentic spare parts;

4. Responsible for free training of operators and providing technical support.

Note: Firstly, a water quality report, hourly processing flow rate, site, etc. are required so that our company can know the specifications and installation status of the equipment!
