Reverse Osmosis
Reverse osmosis (RO) is one of the most popular water purification process that uses a semi-permeable membrane with pose size of 0.0001μm to separate ions, unwanted molecules and larger particles from drinking water. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water.
Ultrafiltration
Ultrafiltration (UF) is a low pressure driven purification process with membrane pore size of 0.01μm, to remove suspended solids, colloidal matter, macromolecules, bacteria and viruses , keep trace elements and minerals in the water. It is widely used in both potable water production and wastewater treatment, such as chemical and pharmaceutical manufacturing, food and beverage processing, and waste water treatment.
