Alkalinity Control
Alkalinity Builder to maintain pH of Boiler WATER available in 20 ltr, 25, 50, 210 ltr. ALKALINITY control products. Principle Mechanism : It converts calcium hardness into soft, non-adherent sludge that is easily removed by blowdown.
Technical Specifications
Testing control procedure
- Test water sample from the water boiler as described in the direction of the Alkalinity Test Kit ( p & m Total ) http://www.rxmarine.com/Alkalinity-test-kit
- Determine the present alkalinity value expressed as ppm CaCO3 .
- Desired level of 100-150 ppm as CaCO3.
- A control test for the alkalinity of the water should be conducted after 3- 6 hours from the application.
Application & Dosage
RXSOL-50-5002-025 provides the alkaline condition for hardness control to function correctly. Without the correct precipitation and subsequent blow down of hardness salt, scale would form. This would result in restriction in water flow, ineffective heat transfer and local corrosion. The end effect would be an inefficient boiler and ultimately component failure. RXSOL-50-5002-025 also provides the alkaline condition required for corrosion control, by neutralization of acidic gases
For optimum results dose RXSOL-50-5002-025 direct to the boiler with a RXSOL Boiler Water Treatment Dosing unit, or via the bypass pot- feeder installed in the boiler feed line.
Required dosage can be controlled by pH & alkalinity test dosage chart .
1 milliliter of RXSOL-50-5002-025 concentrated alkaline liquid per ton of distilled water provides 0.5 ppm of lkalinity hydrate.
Low-pressure boiler (up to 28 bars)
Add RXSOL-50-002-025 to 5 litre in feed – water, There is no any specific method can be passed through the recalculating or the main feed pipe into the stream or the hot well tank.
High – Pressure Boiler (28 to 60 bars)
Dissolve the desired volume of RXSOL-50-002-025 to 5 ltr of feed – water, which should then be passed into the stream or water drum through the chemical pump.
Note:- It can also be used as a neutralizing agent following acid cleaning with descaling materials ( RXSOL-11-1008--DC descaling Liq / RXSOL-54-1008-SA Safe Acid PWD )
