Rajshahi,
Apr 19 (UNB)- Amid countrywide arsenic alarm, a chemist of the country
has invented a cheap method to lessen the arsenic content in water.
Prof
Khandakar Khalilur Rahman, chairman of Rajshahi Education Board, now
leading a movement for “ Arsenic Free Villages” told UNB a family
could get arsenic free water for three months applying his method
expending Tk 200 only.
An
iron frame, three pitchers, a piece of rod, brick bats, three packets
of sands were needed to free the water from arsenic, he said.
Three
pitchers will be set up in the frame from top to bottom and the two
upper pitchers will have tiny holes through which water will
trickledown to the bottom pitcher.
Sands
places on the upper two pitchers will filter off the arsenic element
in water- the third pitcher will have arsenic free water.
Prof
Rahman said the Public Health Engineering Department, Rajshahi region
and a non-government organisation in Kushtia confirmed his method as
effective.
The
method was put on trial at Mirapur village in Charghat thana of the
district on March 28.
He
said he will be more active with the movement of arsenic free village
after retirement from his job in 2001.
Prof
Khalil who taught chemistry as a professor of various government
colleges before the present assignment said he would not commercialise
his method rather he would use it for the welfare of the people.
