Abstract Water purification is a process of removing undesirable chemicals,

biological contaminated, suspended solids and gases from contaminated water.propose water purification system for remote area focus on providing a pure drinking water at low cost with high reliability to the rural families.It involves the research, design and manufacture of water purification system using renewable energy.It consist a combination of natural substances ( moringo seed, papaya seed, tulsi leaves, neem leaves, sugarcane bagase, rice husk).It is an effective method to deactive bacteria, viruses and protozoan in contaminated water. This method can be made portable, cost effective, user compliant and energy efficient enough to meet the drinking water needs.Experimentation is carried out for testing six different water samples.Water samples selected are tap water, well water,river water, lake water, muddy water and colour water.All water are analyzed and tested in a laboratory for different range. This paper will be helpful for those who are working in the area of water purification system and their use in remote area.

KEYWORD: Moringo seed, tulsi leaves , neem leaves.

PROBLEM STATEMENT

TO DEVELOPE WATER PURIFICATION SYSTEM FOR RURAL/REMOTE AREA USING NATURAL METHOD

INTRODUCTIONWater is the most common liquid on the earth pure

drinking water is necessary for human survival.The water supply for drinking water is either ground or surface water. The water from each source contains sediments and other solids.Many different process are used to obtain the finised product of clean water.In remote villages in india, there is lack of of developed infrastructure due to poor economic situation. These remote area do not have pure drinking water,electrical power etc. It is necessary to provide pure drinking water at low cost with high reliability. To accomplish this objective impurities such as sediments must be remove and bacteria must be killied along other microorganism.

REQUIRED RAW MATERIAL :

Neem leavesMoringo seedsTulsi leavesSugarcane baggagePapaya seedsRice huskCharchoalSand

Fig : moringo seeds

The objective of this work are:

To provide the water purification system working on natural based system.

To provide pure water drinking system at low cost to the rural area.

To make the system energy efficient.

To make the system portable and user friendly.

DESCRICPTION:PRIMARY TREATMENT: First the water is collected in tank for sometime

in large tank for sedimentation process.Function of primary treatment to remove the

large as well as medium size of sediments. It will also remove the ordour and the colour and

the some bacteria in some amount. The charcoal is used to remove the presence of

arsenic in some amount.

SECONDARY TREATMENT:The main aim of this treatment to remove the

bacteria,virus as well as antimony from waste water.

The leafs of neem will act as a germicide for the virus and bacteria presents in water. It will also provide the bitterness and colour in small amount.

The neem leafs also remove the ferrous in some amount, when the chuna is used with neem leafs then the % of ferrous removal is increased.

The rice husk is used to remove the ferrous and copper.

It would found by experiments that the papaya seeds are able to seperate antimony from water.

After that water will passed from the moringo seeds powder which is most effective part because it removes the aluminium,bacteria,copper, ferrous,cromium zinc and lead.

When the crushed seeds are added to raw water the proteins produced a positive charge which acts like a magnets attracting particals clay, silt and toxics particles.

The proteins binds the particals by forming flocs which can be easily removed using filters.

It is also used as detoxification and antibiotic.The tulsi leaves is used for removing flourine and as well

as germ killer.Then the water again goes in moringo seeds powder for

removal of colour and ordour.For providing some test the water goes from the

sugercane baggage.

Raw water after passing through moringo seeds powder.

Practically it is found that moringo seeds are able to purified the 90% to 95% turbidity of water.

ADVANTAGES OF THIS METHOD:The process is very economical.The raw material is easily available in India at

low cost.The process is based on natural things.The moringo trees and sugarcane also provide

methane which is used as bio-gas.The method also promotes the plantation of trees

which have great profits for us.The waste product is reusable and at last we can

use it as manure.The water we get at last is herbal and good for

health.

Based on experiment we found that more than 4,400 cubic meter methane could be produced from moringo trees per year.This is twice of methane produced by the sugar beet leaves.

PLANTATION OF MORINGO TREES AND SUGARCANE

DISADVANTAGES:

The process is time taking.Depend on availability of raw materials.

COST CALCULATION:Depend upon approximation and data obtained

from different experiments.Material Rate per kg amount used

per litresSand 15 1 kg(15)Charcoal 80 100 gm(8)Tulsi leaf 300 10 gm(3) Moringo seeds 170 2 to 3 seed

powder(1)Neem leaf 150 20 gm(3)Sugarcane 10 15 gm(.15)Rice husk 7 10 gm(.07)Papaya seeds 200 15 gm(3)

Total cost = 33.22 rs per litreBut the all raw materials are reusable upto

10 to 12 times ,so cost becomes Total cost = 3.02 rupees per litreAnd also sand and charcoal is reusable many

times up to some limits and we get actual cost approx 2.5 rupees per litre and the waste materials are also usable as a manure, making paper.

REDUCTION IN COST :

If we have our own plantation unit for raw materials then the cost is reduces upto 80 % and we gets lots of benefits from trees.

MARKETS POSSIBILITIES :

The bio-gas we get from moringo and sugarcane tree can be used as a subsituents gas(LPG).

Sugarcane baggage is used for making paper.

waste material of the process is used as manure.
