What is the primary application of this chlorinator type?

It's used for disinfecting water in small to medium-sized water treatment facilities, particularly in rural water supply schemes where gas chlorination is not feasible.

What are the specified materials for construction?

The code requires corrosion-resistant materials like Fiber Reinforced Plastic (FRP), PVC, HDPE, or suitable grades of stainless steel to handle the aggressive bleaching powder solution (Clause 4).

What is a major operational challenge with these feeders?

A common issue is clogging caused by impurities and precipitates from the bleaching powder. This necessitates regular maintenance, cleaning, and preparation of a clear supernatant solution.

What is the rated dosing capacity covered by this standard?

The standard covers chlorinators with rated capacities of 200, 400, and 1000 g/h of available chlorine.

Practical Notes

Ensure all wetted parts are made of specified corrosion-resistant materials (FRP, PVC, HDPE) to prevent rapid degradation from the chlorine solution.

These feeders are prone to clogging from insoluble matter in bleaching powder; regular cleaning and use of a settling tank is crucial for reliable operation.

Ideal for rural or small-scale water schemes where simplicity and low capital cost are more important than high dosing precision.
