Any parameter above the
limits as mentioned above will require treatment
Treatment method: Chemical oxidation followed by filtration
Iron or
manganese also can be oxidized from the dissolved to solid form by passing
through oxidizing agent called MNO2.
The resulting solid particles then must be filtered. When large concentrations of iron are present, a flushing sand filter may be needed for the filtering process.
Any filtration material requires frequent and regular backwashing or replacement to eliminate the solid iron/manganese particles. Some units have an automatic backwash cycle to handle this task.

Iron and Manganese removal
Supplied in 25Kg bags
What it is and how it works
MNO2 is a oxidizing agent to precipitate iron and/or
manganese. Because the presence of iron is most common, iron removal is
the usual application for MNO2. Under suitable conditions, the iron and
dissolved oxygen in water react on contact with the MNO2 filter bed and,
as a result, the iron is precipitated in the form of hydroxide. This is a
flocculent material which is filtered out in the bed of anthracite.
Periodic backwashing flushes out the accumulated iron and the MNO2 is
again ready to perform its function. MNO2 is not consumed in the iron
removal operation.
SECOND FILTER:
SAND-ANTHRACITE FILTER FOR IRON REMOVAL
A sand-anthracite filter or
dual media filter/multi-media filter is primarily used for the removal of
turbidity and suspended solids as low as 10-20 microns. Inside a
sand-anthracite filter is a layered bed of filter media. The bed is graded from
bottom to top as follows:
1st layer
|
=
|
gravel support bed
|
2nd layer
|
=
|
2mm filter sand
|
3rd layer
|
=
|
fine filter sand
|
4th layer
|
=
|
anthracite
|
How it works:
Anthracite
has a high affinity for iron, especially when it is coated with potassium
permanganate, and is therefore often employed for iron and manganese removal.

Groundwater contamination cases rising in State
Ajit Patowary
GUWAHATI, Jan 28 - Cases of contamination of groundwater in the State are swelling up everyday, making groundwater unsafe for consumption. According to the official data, the number of the State’s districts which have got their groundwater contaminated by fluoride and arsenic has shot up to 22 and 21 respectively from 19 and 20 respectively in 2014-’15.
GUWAHATI, Jan 28 - Cases of contamination of groundwater in the State are swelling up everyday, making groundwater unsafe for consumption. According to the official data, the number of the State’s districts which have got their groundwater contaminated by fluoride and arsenic has shot up to 22 and 21 respectively from 19 and 20 respectively in 2014-’15.
According to the data available with this newspaper, in 2014-’15, the
arsenic affected districts of the State included Baksa, Barpeta, Bongaigaon,
Cachar, Darrang, Dhemaji, Dhubri, Goalpara, Hailakandi, Jorhat, Kamrup,
Karimganj, Kokrajhar, Lakhimpur, Morigaon, Nagaon, Nalbari, Sivasagar and
Sonitpur.
This year, Tinsukia has also been found to be affected by arsenic,
raising the number of affected districts to 21, said the sources.
Till 2013-’14, nine districts – Barpeta, Dhubri, Goalpara, Golaghat,
Jorhat, Kamrup, Karbi Anglong, Karimganj and Nagaon – were found to be affected
by fluoride.
But in 2014-’15, with the inclusion of Baksa, Cachar, Chirang, Darrang,
Dibrugarh, Morigaon, Nalbari, Sivasagar, Sonitpur and Udalguri, the number of
affected districts rose to 19.
In 2015-’16, with the inclusion of Bongaigaon, Lakhimpur and Tinsukia,
the number of fluoride-affected districts have shot up to 22, sources said.
According to experts here, the trend of rise in the number of fluoride
and arsenic affected districts should be studied, together with the impact of
such contamination of groundwater, which is used by the people of many areas in
these districts for the purpose of drinking as well as domestic use, on human
and animal health.
Except in the two districts of Karbi Anglong and Nagaon, no
comprehensive health impact studies of groundwater contamination in the rest of
the districts has so far been known to have been conducted, said the experts.
The origin of fluoride so far is known to be geogenic.
The State’s Department of Mining and Mineral may undertake such studies,
involving also the Public Health Engineering Department (PHED), Council of
Scientific and Industrial Research (CSIR), Central Ground Water Board (CGWB)
and the North Eastern Regional Institute of Water and Land Management
(NERIWALM) in this regard, said the experts
