Hardness Control Liquid

Hardness Control is a Liquid product used for the reduction of hardness in boilers and to adjust hardness and phosphate. Hardness Control is highly soluble in water and It will precipitate calcium hardness as a non-adherent sludge.

USEFULL  to adjust hardness and phosphate .

A precipitant designed to elimate scale deposits and lower the hardness of water in boilers with working pressure up to 60 bars.

It is used in conjunction with alkaline liquid to prevent calcium scale deposits. Both products are used in our standard boiler water treatment programs for low-pressure boiler systems (0-32 bar) and medium-pressure steam propulsion vessels (32-60 bar).  Reduction of Hardness in boiler water system, and convert these salts in non adherent to avoid scale formation. It will precipitate calcium hardness chemically.

Application

Hardness Control is formulated to form a precipitate with calcium ions which will not adhere to metal surfaces but are in a form suitable for blowdown.


 

Dosage

For optimum results dose Hardness Control direct to the boiler via the bypass pot-feeder. The dry powder should be dissolved in hot water (50°C) at a ratio of 1 part powder to twenty parts condensate (e.g. 500 grams/10 litres). Ensure that treatment is fully dissolved before dosing.

These are recommended values based on experience and are in no way intended to replace the boiler manufacturer's specifications or company regulations.

RXSOL Boiler Corrosion Scale Treatment should be fed continuously in order to properly protect the boiler. Boiler Corrosion Scale Treatment can be fed neat or in any convenient dilution made up in soft water or cooled condensate. Boiler Corrosion Scale Treatment should be dosed using individual chemical dosing unit, must not be mixed with oxygen scavengers or condensate system corrosion inhibitors in concentrated form (e.g. concentrated chemical products should not be mixed together).

Sampling and Testing
Boiler Corrosion Scale Treatment is normally used in conjunction with RXSOL Alkalinity Control treatment in a conventional alkaline phosphate treatment programme for HP boilers, where independent control of phosphate and alkalinity control is required.

Dosing and Control
The dosage of Boiler Corrosion Scale Treatment depends on a number of operational factors such as feed-water quality, boiler design and steam rate. Control of Boiler Corrosion Scale Treatment is by a simple test to give the required level of phosphate (as PO4) in the boiler water. A simple Hardness Treatment test kit is available for this purpose. NOTE: Dependent on water quality, Boiler Corrosion Scale Treatment dosed at 0.25 liters/ton will increase the phosphate reserve by the order of 10mg/l.

Technical Specification

Sampling And Testing

A sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blow down, cooled and tested immediately. Follow the Rxsol Hardness Test Kit instructions and fill the Boiler Water Log Form according to result results. It is important that regular testing is carried out to ensure levels of treatment are correct.
