Alkalinity Control

RXSOL-50-5002-020 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-50-5002-020 also provides the alkaline condition required for corrosion control, by neutralization of acidic gases

For optimum results dose RXSOL-50-5002-020 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 .  
One (1) milliliter of RXSOL-50-5002-020 concentrated alkaline liquid per ton of distilled water provides 0.5 ppm of lkalinity hydrate.
 

Low-pressure boiler (up to 28 bars)

Add RXSOL-50-002-020 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-50-002-020 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 ) 

Testing control procedure

1. 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
2. Determine the present alkalinity value expressed as ppm CaCO₃ .
3. Desired level of 100-150 ppm as CaCO₃.
4. A control test for the alkalinity  of the water should be conducted after 3- 6 hours from the application.
5.  

Alkalinity control makes sludge in soft form, which can be easily blown down from bottom side of BOILER.
