Microfiltration (0.1 to 10 µm) and ultrafiltration (103 - 106Da) are two types of physical filtration process where wastewater is passed through a special pore-sized membrane to separate particles of pollutants from process effluent.

Reverse osmosis is a water purification technology that employs semi-permeable membranes to remove ions, molecules and particles, and to produce potable water. It is widely used in drinking water treatment and desalination.  

Tianjin Motimo Membrane technology Ltd., one of the top world-class membrane suppliers, is our current major supplier of microfiltration, ultrafiltration and reverse osmosis membranes, its Hollow Fibre Membranes Series combine both the advantages in cost-effective and quality of the products.
