Sodium Aluminate Powder Vs Sodium Aluminate Liquor

Sodium aluminate liquor PW Grade (PW = Potable Water)


Instructions for use of liquor and replacement of powder


Sodium Aluminate liquor replaces the use of powder with cost savings in both chemical and application areas some other advances are;

1. Health hazards due to dusting problems are eliminated. 2. Dissolving and make up is eliminated reducing accident risk.

Specification
Sodium Aluminate Liquor PW Grade is manufactured to high standards of purity and does not contain organic stabilizing agents. It is a potable grade for drinking water and has been accepted by the British Water Research Association.
The Specification on chemical analysis and impurities is attached.


Dosing amounts powders or solution
The comparison of relative weights is as follows:-


WT required kg Volume litres Approx relative cost
Sodium Aluminate Powder 1.00 Solid 1.00
Sodium Aluminate Liquor 2.20 1.09 0.80



Additional savings are made in capital cost for tanks and labour for make-up.

Concentration and dosing

SODIUM ALUMINATE LIQUOR SHOULD BE DOSED OR USED DIRECT FROM THE DRUM

Diluted aluminate causes build up of alumina precipitation in pipelines. The particularly applies to powders.

Dosing directly, for example, from drums using a pump eliminates such problems.

We advise the use of peristaltic pumps for discharge from 200 litre drums as;

1. Positive pumping is obtained. 2. if the tubing waers and breaks the pumping action automatically ceases.

THE PUMP SHOULD BE PLACED ON THE DRUM OR ABOVE THIS LEVEL.

Dosing using the concentrated liquor reduce pump size requirements by at least 200%. Alumiante liquors made up from powders cannot be made up to levels above 10% and this level causes difficulty.

EASY DOSING ARRANGEMENT FOR LIQUOR




In stream mixing

FOR GREATEST EFFECT ENSURE RAPID OR FLASK MIXING.

For example - inject into highest water velocity point in a pipeline.
