Water desalination ppt

Water used for this process is sea water , by using this process sea water is processed in to drinking water. The Minjur desalination plant consists of 6sea water RO membranes, 2pressure vessels, pressure exchangers, five high-pressure pumps , pressure filter vessels, electrical, automation and control systems, and a 200m of HDPE pipeline of 600mm diameter. Desalinization A Desalinization Plant Can Produce Roughly Million Gallons Of Water PPT Presentation Summary : A desalinization plant can produce roughly million gallons of water a year. To increase the thermal efficiency of this plant , the maximum number of stages is set to (MSF) Research in the field is resulting in more plants coming up in Florida and California Questions?

A desalination process essentially separates saline water into two parts - one that has a low concentration of salt (treated water or product water ), and the other with a much higher concentration than the original feed water , usually referred to as brine concentrate or simply as ‘concentrate’. The benefits of desalination are straightforward: more water.

The drawback, unfortunately, is the cost and Environmental impact. The process of desalting seawater is essential to have water storage for municipal use. Childress Department of Civil and Environmental Engineering University of Nevada, Reno 1st Arab-American Frontiers Symposium Kuwait Institute for Scientific Research and U. The thermal desalination approach involves heating saltwater until it evaporates and then forcing the evaporated water to condense. The condensed water is clean water.

This type of process is used to produce more than of the desalinated water in the world. Seawater Reverse Osmosis (SWRO) is a very robust and widely practiced desalination technique. Through many years of experience it has been learned that the key to any successful reverse osmosis (RO) process is the pre-treatment.

In ancient times, many civilizations used this process on their ships to convert sea water into drinking water.

Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the worl and to treat water in other areas that is fouled by natural and unnatural contaminants. TDS ƒFresh water for human consumption should not exceed 5ppm TDS. Saline water is classified as either brackish water or seawater depending on the salinity and water source. To do this economically in a desalination plant, the applied pressure of the water being. The paper provides a critical overview of water desalination using geothermal resources.

Specific case studies are presente as well as an assessment of environmental risks and market potential and barriers to growth. UK for the supply of drinking water. In addition, its water recovery rate is relatively higher, as one tonne of desalinated water can be produced with an input of 2. In the Persian Gulf, where seawater normally contains a lip-puckering grams of salt per liter, thermal desalination is king. This method vaporizes water to purify it.

Pretty much everywhere else, desalination is done by reverse osmosis, which purifies water by forcing it through membranes. Desalination produces two streams - freshwater and a more concentrated stream (brine). The most common desalination processes are distillation and reverse osmosis. RO by first filtering the raw seawater with Norit X-Flow Seaguard UF membrane modules.

With its specialized membrane geometry and characteristics, Seaguard offers the highest quality SWRO feed water. This guarantees years of trouble-free desalination at the lowest cost possible. Concentrate disposal methods in Texas, Texas Desal Conference, Austin, TX.

Membrane Distillation (MD) is a water desalination membrane process currently in limited commercial use.

MD is a hybrid process of RO and distillation in which a hydrophobic synthetic membrane is used to permit the flow of water vapor through the membrane pores, but not the solution itself. Water treatment and desalination from Veolia provides municipalities and industry with potable and process water from brackish water and seawater. Municipalities: Veolia has the capacity and resources to construct large-scale, permanent desalination plants. The desalination facility uses seawater reverse osmosis (SWRO) process providing water to Israel’s national water carrier. Improvements to thermal desalination technologies and low-cost, integrated designs for solar-thermal collection and storage.

From the earth surface water , 97. With the advances of desalination technologies, sea water has become an interesting water source to cope with fresh water shortage. This process can be applied wherever a reliable source of water is needed.
