The present study is on the purification of sewage water for agricultural purpose by using various chemicals and natural
absorbent (rice husk charcoal &Activated charcoal). The sewage water is collected and conduct pre-treatment test for various
parameters like p
H
, Hardness, Total dissolved solids, Total suspended solids, BOD, COD , Dissolved Oxygen, Chlorides content.
Then coagulant with rice husk ash, charcoal the rice husk ash is prepared by using muffle furnace at 100
o
C.
The rice husk is low in cost and easily available. Treating of sewage water with rice husk ash & charcoal helps to decrease the
p
H
, BOD, COD, Total hardness, chlorides ,TSS,TDS . The filtration is done by using whatsman filter paper. After the filtration,
check the parameters like p
H
, Hardness, Turbidity, Chloride, Total Dissolved solids, Total Suspended solids. After post
treatment process p
H
, BOD, COD, Chlorides TSS, TDS, and Hardness are decreased. By using natural absorbent (rice husk char
& charcoal).The values are neutralized at 3% of coagulant.
Keywords: Human power, Rice Husk, Activated Charcoal, Chemicals.
1. INTRODUCTION
Water is considered as one of the most important nature of the earth. It is one of the most important things that is required by
every living organism. Water covers about 71% of the land on the earth’s surface, of which 96.5% of the planets crust water is
found in seas and oceans, 1.7% in form of ground water, 1.7% in the glaciers and the ice caps of Antarctica and Greenland, a
small fraction in other large water bodies, 0.001% in air as vapour, clouds and precipitation. Only 2.5% of this water is fresh
water, 98.5% of water is in ice(excepting ice in clouds) and ground water. Less than 0.3% of all freshwater is in rivers, lakes,
and in the atmosphere, and even a smaller amount of the earth fresh water (0.003%) is contained within biological bodies and
manufactured products.
1.1 Sewage water
Sewage is a water-carried waste, in solution or suspension that is intended to be removed from a community. More than 95%
of water is characterized by rate of flow, physical condition, chemical constituents and bacteriological organisms that it
contains. Implementation of conventional sewage treatment reduces vector and odors problems of water. Urban areas in India
generated about 5 billion liters a day of wastewater in 1947 which has increased to about 30 billion liters per day in 1997.
1.2 Importance of Sewage water treatment
The principal aim of sewage water treatment is generally to allow the human and industrial effluents to be disposed of without
danger to human health and natural environment. We consider wastewater treatment as water use because it is so
interconnected with other uses of water. Most of water used by homes and industries must be tested before it is released back
to the environment. If we didn’t treat the billions of gallons of wastewater and sewerage produced everyday then it will cause
huge quantity of water pollution.
Treatment plants reduce pollutants in sewage water to a level nature can handle. Sewage water is used water.
Rice husk is one of the natural adsorbent which is used in the sewage water treatment as filtrate material. Activated char coal
is the other material used for filtration. It shows good results in the removal of the physical and chemical parameters of
sewage water and make it fit for reuse, which can be used in secondary purposes.
