5. Use areas

Drinking water

Reclaimed and recycled water

Waste water

Recirculating cooling water systems

Air conditioning waters

Food and beverages process water (primary disinfection)

Industrial air washers

Oil field waters

Water storage tanks

6. Recommendations to formulate

Mixing with any other chemical has to absolutely avoid.

7. Analytical procedure

Determination of the chlorine content through standard titration using potassium iodine

and sodium yhiosulfate.

8. Packaging/Storage

Product is supplied in 45 kg plastic pails. HTHTM

Briquettes can be stored up to 2 years after its manufacturing

date under normal temperature and humidity conditions.

However, there is a potential for slow release of gases, primarily chlorine gas in very limited quantities due to

the degradation of the material over the time.

The product must be kept protected from light. Drums must be stored upright in a well ventilated area with

containment facilities. Drums must be handled carefully when lifted and moved.
