Technology Name

Gravity ultrafiltration membrane technology

Technical principle

Gravity ultrafiltration membrane as the core, optimize and improve the existing water purification system in the membrane system operation: First, remove the water production pump, relying on the gravity ultrafiltration membrane itself excellent hydrophilicity, to achieve the design value of water production; Second, the process flow has been greatly simplified, to achieve the ultra-short process of direct membrane filtration after coagulation, while reducing the accessories supporting items, maintenance is more simple. Third, the air washing system completely replaces water backwashing and chemical cleaning, off-line cleaning system, which reduces the complexity of membrane system maintenance and avoids secondary pollution accompanying the maintenance process; fourth, the water production method is improved, and no aeration is required during water production, which reduces electricity consumption.

Scope of application

It can be used in the field of industrial enterprise water supply: With the serious groundwater over-exploitation and the national policy to implement management, the source of enterprise water supply is gradually shifting to surface water source, and the "gravity ultrafiltration membrane ultra-short process water purification process" is especially good at the application of surface water deep purification, and the construction cost and operation cost can be significantly reduced under the same water production conditions.

Process flow and description

Promotion prospects

The improvement of ultra-short flow water purification process with gravity ultrafiltration membrane as the core greatly reduces the floor space, power consumption of water purification treatment, chemical input and maintenance cost, and has high promotion value.

1．In gravity ultrafiltration water purification system, the membrane system is greatly simplified to achieve ultra-short process depth treatment, which greatly reduces the floor space and significantly reduces the cost of water purification plant renovation and new civil construction investment costs.

2．operation mode, reduce power consumption, gravity membrane filtration water production, completely replace the pumping water production method, water production process does not require aeration, further reducing power consumption, energy saving excellent.

3．Simple process flow, thus more stable operation, not easy to damage, significantly reducing maintenance costs.

4．The membrane has excellent tolerance and strong anti-pollution ability, and the unique gas cleaning system completely replaces chemical agents and water backwashing system, simplifying the process, reducing the cost of chemical consumption and greatly extending the service life.
