Dears

I have to choose between two products of calcium hypochlorite ( HTH Easiflo Granules and HTH Shockfrom) from Accepta company to Sterilization permeate water from reverse osmosis which use for Dairy Processing. please for your recommendation and advice

Thank you

Depends on what type of feed system that you plan to use.

With the Shock which is a finer grade material, you probably need a day tank with mixer. If the material sits around for a long time, it will go stale.

HTH has a feeder for the Easiflow briquettes so there is probably less waste and simpler to use.

Dear Bimr

please what do you mean by feed system?

Thank you

 

[bimr]

The feed system is the day tank, mixer, metering pump, and control system to enable "feeding" the chemical.

The briquettes can be used with a solution feeder:

While the fine material would have to be used with a day tank and pump.

actually i have already day tank, mixer, metering pump. so can i use both of them and what is the advantage and disadvantage for both of them

Thank you

 

[bimr]

The Shock has 10% more chlorine and dissolves quicker. That is the best option for the money.

 

[wwtp2014]

Do you mean i can use HTH Easiflo Granules with make up tank equipped with mixer and conical bottom, dosing tank with metering pump.so no need for feeder.
and for economic option HTH Easiflo Granules cheaper than Shock type for Kg

 

[bimr]

Correct, you can use either the shock or the granules in a tank system.

This material is not food grade, but has met various standards for potable water use.
