Introduction of Laboratory and Industrial Filter Membranes
The filtration of filter membranes is solid-liquid separation technology, no chemical change, simple processing. There is no need for flocculation chemical treatment or evaporative separation when using the filter membranes device. It only needs the pressure to separate solid and liquid in water, which is a major feature of filter membrane treatment.
The material of the lab filter membranes
1. Glass fiber;
6. Cellulose acetate
Water treatment membrane filtration method
1. The liquid passes through the membrane hole vertically to retain impurities in the liquid;
2. The flow direction of the liquid is equal to the membrane surface, forming a cross-flow filtration mode in which the liquid and the membrane surface pass through the membrane holes at right angles and impurities in the liquid are trapped.
In addition to being used for water treatment, filtration membranes can also be used for ultra-pure water manufacturing and seawater desalination, generally using reverse osmosis membrane. In addition, it is used for the treatment of feces and urine, urban waterways, and various wastewater, etc., generally using ultrafiltration membrane and microfiltration membrane.
