New Technology Using Vacuum Collector Tube for Saving Water - Research Paper Example

The advantage of Water Purification can be used to produce large quantities of recycled water, so this process is applied to treat sewage water in dense regions of people, on the other hand, Putrefaction stations cause many problems such as odors and noise. Water distillation technology is the second method used to treat wastewater based on differences in their volatilities (Hician, 2005). sewage water is heated to boiling point by the heat exchanger, then the steam is condensate into the specific storage-tank, high purity water is produced by this method, relatively high energy is consumed to run these heaters, and pumps which are included within distillation system.

Solar energy can be used as energy sources because the earth receives 174 PW per day of incoming solar radiation at the upper atmosphere, 30 % is reflected back to space while the other is absorbed by clouds, oceans, and landmasses. This type of energy is an alternating one, so there is a limitation to use this source of energy for its utilization in the project to do meaningful work as is associated with the use of the energy. 1.2 SCOPE Vacuum collector tube technology is a new application for solar energy that can be used to get hot domestic water; each evacuated tube consists of two glass tubes (Trinkl, 2005) as shown in Fig.

1, the outer tube is allowing light rays to pass through with minimal reflection where the inner tube is coated by selective coating to increase the radiation absorption, the vacuum is performed by special gasses such as Co2, in additional a barium getter can be used in the manufacturing process of the evacuated tube, this getter is exposed to high temperatures which cause the bottom of the evacuated tube to be covered with a thin layer of barium. This layer absorbs any CO, CO2, N2, O2, H2O, and H2 out-gassed from the vacuum tube collector during storage and operation, to eliminate heat loss through convection and conduction modes.
