Ultrafiltration is becoming a preferred alternative as pretreatment to sea water reverse osmosis plants delivering superior water quality to reverse osmosis.Alternatives for seawater pretreatment
Seawater pretreatment is an integral part of every Seawater Reverse Osmosis (SWRO) desalination plant. The key purpose of the pretreatment system is to remove particulates, debris, micro organisms, suspended solids and silt from the source seawater prior to reverse osmosis sepration.Chinese power plant overcomes challenges of seawater for use as process water
Water is a notoriously scarce resource in northern China, a situation that has forced many industries in the region to turn to desalination for process water. Located in HeBei province close to the Bohai Sea, the WangTan Power Plant has a 2x600MW capacity. The Bohai Sea has high turbidity that …Purifying water at point of use
Deepak Saksena, Country Director, AED (Academy for Educational Development) India, in conversation with Rakesh K. Singh onDecentralised wastewater management using constructed wetlands in Nepal
Environment management is a significant challenge in developing countries mainly due to lack of strong legislation to control wastewater and institutional capacity for integrated planning and management. This paper describes the importance of small scale decentralized wastewater treatment using reed bed treatment systems in Nepal. It shows how public/community participation …Decentralised wastewater treatment making strides
Over 80 per cent of water consumed in flats and buildings comes out as wastewater. In un-sewered areas, the conventional practice has been to use a septic tank as the recipient of wastewater flows and the liquid effluents then emerging being led into soak pits or leaching trenches. This form …Conserving water in membrane treatment systems for drinking water & softening applications
Point of use (PSU) reverse osmosis (RO) drinking water systems and point of entry (POE) ion exchange water softeners are two of the most universal water treatment technologies used today for residential and commercial locations. However, these systems have operational characteristics that limit their use if installed in water short …Testing water: Treatment products for bacteria removal
Bacteria, viruses and cysts represent the three types of microbiological contaminants that may be found in water. Following this occurrence pattern, the NSF task group on microbiological standards has proposed a requirement that bacteria reduction claims are accompanied by tested claims of virus reduction and cyst reduction.Water dispensers: Indian scenario
