purification of water using solar stillMohamed Ahmed
Distillation is one of many processes that can be used for water purification. This requires an energy input as heat, electricity and solar radiation can be the source of energy. When Solar energy is used for this purpose, it is known as Solar water Distillation. Solar Distillation is an attractive process to produce portable water using free of cost solar energy. This energy is used directly for evaporating water inside a device usually termed a “Solar Still”. Solar stills are used in cases where rain, piped, or well water is impractical, such as in remote homes or during power outages. Different versions of a still are used to desalinate seawater, in desert survival kits and for home water Purification. For people concerned about the quality of their municipally-supplied drinking water and unhappy with other methods of additional purification available to them, solar distillation of tap water or brackish groundwater can be a pleasant, energy efficient option. Solar Distillation is an attractive alternative because of its simple technology, non-requirement of highly skilled labour for maintenance work and low energy consumption.
The use of solar thermal energy in seawater desalination applications has so far been restricted to small-scale systems in rural areas. The reason for this has mainly been explained by the relatively low productivity rate compared to the high capital cost. However, the coming shortage in fossil fuel supply and the growing need for fresh water in order to support increasing water and irrigation needs, have motivated further development of water desalination and purification by renewable energies.

'Namami Gange Programme', is an Integrated Conservation Mission, approved as 'Flagship Programme' by the Union Government in June 2014 with budget outlay of Rs.20,000 Crore to accomplish the twin objectives of effective abatement of pollution, conservation and rejuvenation of National River Ganga.
The river Ganga is the most important and religious river of India. Ganga is a Himalayan River and is passes through five states such as Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal in a length of 2500 Km. In Bihar, it enters at Chausa (Buxar District) and travels a distance 445 km upto Manihari (Katihar District). At the entry point of Bihar the discharge of the river Ganga is approximately 400 cumecs and it becomes approximately 1600 cumecs when the rives leaves Bihar. The Ongoing/ Proposed actions in the stretch of river Ganga are as follow:-
A. Liquid Waste Management:-

2. Ground water is perhaps the most accepted
source particularly in areas where safe and
dependable surface water sources are not
available within easy reach or not available at
all.
Ground water is generally considered as a
safe source but in recent times research and
investigations have shown that quality of
ground water has deteriorated at many
locations thus making it unfit for use for
human consumption. In Bihar excessive
levels of arsenic and fluoride in ground water
have been noticed in many areas.
Public Health Engineering Department, being
conscious of this serious problem has decided
to install small water purification plants for
treating ground water drawn through tube
wells and supplying the treated safe water
local through stand posts to the consumers.

uPVC Pipes and Fittings have been used as:
uPVC pipes being lead free so are non-toxic and
hence favoured for use in applications such as
potable water pipes. Selected and used
Do not corrode and are totally unaffected by Acids,
Alkalies and electrolytic corrosion from any source
Have extremely smooth bore due to which frictional
losses are at minimum and flow rates are at the
highest possible from any other pipe materials
Low friction loss & UV Resistant
Due to smoothness of inner surface of the pipe, it
prevents Algai, Bacteria and Fungi Formation inside
the pipe
Solvent joint plumbing system makes its pressure
bearing capacity twice than that of the threaded
pipe
