Chlorine |
|
Chlorine is a non flammable compressed gas, greenish yellow in colour and primarily a respiratory
irritant. Is an oxidizing and disinfecting agent used for the treatment of potable water as well as
swimming pool sanitation. It is available in both 1000 kgs and 100 kgs.
Handing of Chlorine should be under the direction of thoroughly trained personnel who are fully
familiar with all of the hazards and safeguards necessary for the safe performance of the work.

Magnafloc LT22S - coagulant aid |
|
- Magnafloc LT22S is a very high molecular weight cationic
polyacrylamide, supplied
as a free flowing, white granular powder. It is specifically
designed for thickening
and dewatering of coagulant sludge. Processes used are
centrifuge, pressure
filtration and gravity thickening. It is also used a coagulant
aid for clarification
and filtration processes.
