SMF – Submerged Membrane Filtration

Submerged membrane filtration (SMF) technology is a type of membrane filtration process in which ultra-low-pressure hollow-fiber membrane technology and continuous membrane filtration technology are combined together.

It uses open-ended hollow fiber membrane elements, which put the membrane directly into the membrane tank that is full of water, then go through the vacuum suction pump, use  atmospheric pressure, so that the surface water can  go through the membrane, get out from the inside, and the purpose of purification is achieved.
The  daily treatment capacity of the single membrane tank can reach more than 10,000 tons.

The combination of more than one membrane and backwash operation can be adapted to different water conditions and scale, so that the control system of water treatment can be greatly simplified, and  the reliability is greatly improved. It is especially suited for large-scale water treatment work.
The technology can help hollow fiber membrane achieve on-line cleaning and online chemical enhancement cleaning, the elimination of membrane fouling and an effective restoration of membrane flux.

The technology can achieve integral online test for the membrane. No matter when you have any problem with membrane, it can be judged quickly and accurately, and can be easily isolated  and replace the membrane.
Submerged membrane filtration (SMF) technology is a research result from MOTIMO after many years’s research of ultra-low-pressure membrane filter technology, development and the accumulated experience of practical application. It is an international advanced technology after the birth of CMF, MBR, TWF. MOTIMO has the integral intellectual property rights on technique.
