With the technological advances of small plant performance and reliability, decentralized wastewater treatment plants have now become eminently feasible.

EWT UNR TM MBR system incorporates flat-plate, micro filtration membranes. Since 1990, many wastewater treatment plants have been built based on this technology around the world.

Sand filters treat most of our drinking water supplies, and they are the most common filtration technologies used for waste water, sewage effluent, and grey water recycling and water treatment in general.

The introduction of the axial piston pumps and the development of energy recovery units especially for seawater reverse osmosis has changed the system design dramatically and reduced the energy consumption by up to 80% in these installations. Oct-Dec 2007

Membranes are key components in the majority of plants treating waste water for recycle. These days there are not only relatively small scale plants recycling waste water in factories but also large scale plants treating waste water from cities for recycle. Oct-Dec 2007
