The TMF Series: (Anti-Pollution Membrane, suitable for complex water quality such as surface water and wastewater) TMF20-400, as a professional anti-pollution membrane, has a wide range of application scenarios, covering all fields that need to deal with complex water quality, and its core value of "anti-fouling and stable operation" can better meet the needs of different users.

First, surface water treatment. For water supply projects that take surface water (such as rivers, lakes, reservoirs) as the water source, the water quality is often affected by seasons, rainfall and human activities, with high turbidity, high content of suspended solids and organic matter, and easy membrane fouling. TMF20-400 can effectively intercept impurities, resist fouling, ensure stable water production and qualified water quality, and provide safe and reliable water sources for urban water supply, rural water improvement and other projects.

Second, industrial wastewater treatment. Industrial wastewater (such as printing and dyeing wastewater, chemical wastewater, food processing wastewater) has complex components, high concentration of organic matter, heavy metals and other harmful substances, which is a great test for membrane products. TMF20-400 has strong anti-pollution and corrosion resistance, can stably operate in harsh wastewater environments, realize the recycling of wastewater, reduce environmental pollution, and meet the environmental protection emission standards.

Third, municipal sewage advanced treatment. Municipal sewage contains a large number of microorganisms, suspended solids and refractory organic matter. After conventional treatment, it is difficult to meet the reuse standards. TMF20-400 can further purify the secondary effluent of municipal sewage, remove residual impurities and pollutants, realize the reuse of reclaimed water, and alleviate the shortage of water resources.

It can be directly matched with the existing water treatment system, without major modification of the system, and is suitable for various complex water quality scenarios such as surface water, industrial wastewater and municipal sewage. At the same time, it can adapt to a wide range of temperature and pH value, with strong environmental adaptability.

Sixth, energy saving and environmental protection. The recommended operating pressure is low, which can reduce the energy consumption of the water pump, save energy and reduce consumption. At the same time, the membrane material is non-toxic and harmless, and the waste membrane can be recycled, which is in line with the global low-carbon environmental protection development trend.

First, pre-installation preparation. Before installation, check the integrity of the TMF20-400 membrane module, confirm that there is no damage to the membrane filaments and seals; clean the water treatment system pipeline, remove impurities such as rust and sediment in the pipeline, avoid damaging the membrane module; prepare installation tools, seals, pressure gauges and other materials.

Second, membrane module installation. Install the TMF20-400 membrane module into the membrane tank according to the installation instructions, ensure that the connection is tight, and there is no water leakage; connect the water inlet, water outlet and cleaning pipeline, and install pressure gauges and flow meters to monitor the operating parameters in real time.

Third, system commissioning. After installation, turn on the water source and power supply, adjust the operating pressure to 0.1-0.2MPa, and the flow rate to the recommended value; run the system for 30-60 minutes, check whether the water production is normal, whether there is water leakage in each connection, and adjust the parameters in time if there is any abnormality.

Fourth, normal operation. During normal operation, regularly monitor the operating parameters (pressure, flow rate, water quality), and record the data; if the operating pressure increases by more than 0.1MPa or the water production decreases by more than 20%, it indicates that the membrane is fouled and needs to be cleaned in time.

Fifth, membrane cleaning. Prepare the cleaning solution (weak acid or weak alkali cleaning agent, diluted according to the ratio of 1:15-1:25), pour it into the cleaning tank, connect the cleaning pipeline, and circulate the cleaning solution at 25-35℃ for 30-60 minutes; after cleaning, use clean water to rinse the membrane module for 10-15 minutes until the effluent is neutral, and then restart the system.

Sixth, daily maintenance. After the system is shut down, flush the membrane module with clean water for 5-10 minutes to remove the residual impurities on the membrane surface; regularly check the seals and membrane filaments, and replace the damaged parts in time to ensure the stable operation of the system.

7. Working Principle

The working principle of TMF Series: (Anti-Pollution Membrane, suitable for complex water quality such as surface water and wastewater) TMF20-400 is based on the physical sieving effect and the anti-pollution mechanism of the membrane material, realizing efficient filtration and purification of complex water quality while resisting fouling.

First, physical sieving principle. The TMF20-400 membrane has a uniform pore size of 0.1-0.2 μm. When the complex water passes through the membrane under a certain pressure, the suspended solids, colloids, microorganisms and other impurities larger than the pore size are intercepted on the surface of the membrane, while water molecules and small molecular substances pass through the membrane, achieving the purpose of water purification.

Second, anti-pollution mechanism. The modified PVDF membrane material has strong hydrophilicity, which can reduce the adhesion force between the membrane surface and organic matter, microorganisms and other impurities, making it difficult for impurities to adhere to the membrane surface; at the same time, the unique surface structure of the membrane increases the surface roughness, reduces the contact area between impurities and the membrane, and further enhances the anti-fouling performance. In addition, the membrane filaments are arranged in an orderly manner, which can reduce the accumulation of impurities between the membrane filaments and ensure the smooth flow of water.

Third, flux stability principle. During the operation process, the reasonable operating pressure and flow rate are controlled to make the water flow through the membrane surface at a certain speed, which can generate a gentle scouring force, wash away the impurities attached to the membrane surface in time, avoid the blockage of the membrane pores, and maintain the stable water production flux of the membrane.
