AI Technical Summary
Existing ultrafiltration membranes are susceptible to fouling during operation, resulting in high equipment investment costs, difficult maintenance, and high energy consumption. Furthermore, they are difficult to maintain in remote rural areas where there is no power supply.
The system employs a non-powered water purification system, including an ejector, membrane module, and product water tank. It utilizes a pulse aeration device and a gas outlet pipe to achieve backwashing of the membrane filtration device. The membrane surface is flushed by gas aeration. The system has a simple structure and requires no electric drive.
It achieves low-cost and easy-to-maintain water purification, reduces the probability of equipment damage, and can effectively flush the membrane surface even without electricity, thus improving its anti-fouling ability.
