Low cost Arsenic Fluoride Filter
LOW COST ARSENIC & FLUORIDE FILTER
INTRODUCTION:
What
are the possible health effects of arsenic in drinking water?
According
to a 1999 study by the National Academy of Sciences, arsenic in drinking water
causes bladder, lung and skin cancer, and may cause kidney and liver cancer.
The study also found that arsenic harms the central and peripheral nervous
systems, as well as heart and blood vessels, and causes serious skin problems.
It also may cause birth defects and reproductive problems.
WHO Standards for Arsenic:
The World
Health Organizations (WHOs) current provisional guideline for arsenic in
drinking water is 10 ppb. In India, states like Uttar Pradesh, Bihar,
Jharkhnad, West Bengal, Assam, Manipur, mainly in Ganga-Meghna-Brahmaputra
(GMB) plain covering an area of about 569749 sq km with a population of over
500 million have reported serious illnesses due to presence of arsenic.
.
TECHNOLOGIES AVAILABLE FOR ARSENIC FLUORIDE REMOVAL:
Activated Alumina and Reverse Osmosis (RO) are
the only two methods for removing fluoride and arsenic.
About Activated Alumina
Activated alumina is a filter media made by treating aluminum ore so that it becomes porous and highly adsorptive. Activated alumina will remove a variety of contaminants including excessive fluoride, arsenic and selenium. The medium requires periodic cleaning with an appropriate regenerate such as alum or acid in order to remain effective. During the process about 5–10% of the alumina is lost and the capacity of the regenerated medium is reduced by 30–40%. The activated alumina needs replacement after 3–4 regenerations
FLOW CHART :
Pond/well---Pump---Iron Filter----Activated Alumina Filters---Activated Carbon Filter----UV Tube disinfection----Collection Tank----Supply by 20 Ltr JAR
DESCRIPTION OF PARTS OF THE SYSTEM :
The Iron filter with iron removal media is very high efficiency in Iron, turbidity and bacterial removal.
The Activated Alumina Filter removes both Arsenic and Fluoride. This is a WHO approved conventional method applied all over the world..
The Activated Carbon filter removes residual colour ,odour and Iron. Also it removes the bad effects of activated alumina.

Source of Water : Pond, WellTo provide 10 liters per capita per day (LPCD) of safe drinking water for drinking and cooking purposes in areas affected by fluoride, arsenic, heavy metals and pesticides.
Quantity: 3000 Liter per day (For 300 persons @10 liter per person per day ).
To design a system we need
1. The total quantity of water to be treated
2. A water test is recommended.
FOR A SINGLE HOUSE: 1000LPH FRP Vessel Filter with Arsenic fluoride media .Cost:Rs.40,000/=

FOUR KALSHI FILTER AT VILLAGE( Removes Iron, Fluoride, Arsenic)
Description
A homemade, four-pitcher filter unit, one of the simplest and most inexpensive ways treat drinking water. The first pitcher contains coarse sand. The second contains activated alumina, third pitcher contains activated carbon, and the fourth collects the filtered water.
A sari cloth is sometimes used as an additional filter between the top 2 kalshi.
