Water Desalination

Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance,[1] as in soil desalination, which is an issue for agriculture.Due to its energy consumption, desalinating sea water is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation.UNIMAS Water Desalination Laboratory is led by Prof. Dr. M. Shahidul Islam as the Principal Researcher of UNIMAS Water Desalination projects. Prof. Dr. M. Shahidul Islam is an academic staff with the Faculty of Engineering, UNIMAS and has been active in the field of water desalination since 1995.The main objectives of the water desalination research are firstly, to produce fresh water from saline water sources (river and sea) by using green technology and secondly, to produce fresh water from the industrial wastewater stream using zero waste discharge technology.

Water Ultra-filtration

Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. The pore size of the ultrafiltration membrane is usually 103 - 106 Daltons. Ultrafiltration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density.
