|
Water Treatment |
| The catalyst is a blend of
activated minerals heat treated / calcined in reducing
atmosphere and agglomerated and again calcined at low
temperature to make it a good media to adsorb iron,
manganise, cao, mgo, alumina and partly dissolved
silica. This works well with 6 to 8 PH in domestic use
of well water, underground water not usable as it comes
out and from other sources rich in impurities and
hardness. |
|
|
|
Process |
|
The water is passed through the media (Catalyst) (size
4mm to 40mm) with calculated contact time and comes out
without the impurities or partly improved. In the latter
case it may require recycling or more contact time. The
size available is chosen as per the requirement of the
input quality and the capacity desired. |
|
|
|
Back Wash |
|
In domestic use the back wash is required once in 6 days
or a week. |
|
|
|
Domestic System |
|
The equipment consistis of 2
concentic PVC pipes outer of 5” dia and inner of 1 ½
dia, length 5 ½ ft. the space between the pipes is
filled with the media upto ¾ th of the length. |
|
Water percolates from the top
(vertical section) through the media and enters through
the bottom to the inner pipe and comes out from top-
purified. |
|
|
|
Capacity 500 lt/hrs. |
|
The capacity can be increased to any extent by
increasing the contact area and flow of water. |
|
|
|
Industrial Units |
|
Welding aid manufacturers with acidic effluents of about
1% acidity. This has to be treated before taking in the
system. We could do it by treating with NH3
only 500 ml of NH3 was required for 100 lit.
of effluent. |
|
|
|
At the neutral stage (7PH). The iron, silica, alumina
precipitates. This can be passed through a filter or
permitted to settle and the passed through the media to
absorb the impure elements. This can increase the speed
of operation without affecting the media. |
|
Action of media (Catalyst) - The media adsorbs the
impure elements in Hydroxide form and retains it like a
magnet. |
