Part No: RXSOL-50-5002-025
Alkalinity Builder Very usefull Concentrated Alkaline Liquid For Maintaining Ph which protects corrosion, scalling by controlling Calcium scale in water system.
Boiler Water Treatment Chemicals Concentrated liquid alkaline product for corrosion and Calcium scale control in boilers. Very usefull Concentrated Alkaline Liquid For Maintaining Ph - To adjust alkalinity.
Suitable for Low-pressure boiler systems (0-32 bar) , medium-pressure steam propulsion vessels (32-60 bar). And also suitable to used for high pressure steam generating systems (60-84 bar).
Mechanism : It converts calcium hardness into soft, non-adherent sludge that is easily removed by blowdown.
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 )
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.

5. Working Principle
RXSOL ALCA SOLUTION increases the alkalinity of boiler water and helps maintain the required pH.
Proper alkalinity control helps minimize corrosion caused by acidic conditions and supports the performance of other boiler water treatment chemicals.
However, excessive alkalinity may contribute to foaming, carryover, caustic concentration and other operational problems.
The treatment must therefore be controlled through regular boiler water analysis.
6. Directions for Use
-
Test boiler water pH and alkalinity.
-
Compare the results with the boiler manufacturer's recommended operating limits.
-
Calculate the required chemical dosage based on the boiler water volume and product concentration.
-
Introduce the chemical through an approved dosing system.
-
Allow adequate circulation and mixing.
-
Retest the boiler water and adjust dosing as required.
-
Maintain appropriate blowdown and routine water testing.
Important: Do not dose concentrated alkaline chemical directly into an unsuitable or isolated section of the system. Follow the equipment manufacturer's chemical injection requirements.

10. Frequently Asked Questions
Q1. What is RXSOL ALCA SOLUTION used for?
It is intended to raise and maintain boiler water alkalinity and pH.
Q2. Can it prevent boiler corrosion?
Maintaining proper alkalinity helps reduce corrosion caused by acidic boiler water, but complete corrosion control also requires appropriate oxygen control and overall water chemistry management.
Q3. Can it be used with oxygen scavengers?
It may be incorporated into a boiler treatment programme containing a compatible oxygen scavenger. Concentrated products should not be mixed directly unless compatibility has been confirmed.
Q4. Is ALCA SOLUTION the same as a condensate neutralizing amine?
No. ALCA SOLUTION is intended primarily for boiler water alkalinity control. Neutralizing amines are used mainly to control pH and carbonic acid corrosion in steam and condensate systems.
Q5. What is the recommended dosage?
Dosage depends on the chemical concentration, boiler water analysis and operating requirements. A product-specific dosage cannot be established without these details.

Technical note: This bulletin assumes ALCA SOLUTION is an alkaline boiler water treatment product. If your product is instead an alkaline tank cleaner or a different formulation, its description and applications will need to be revised accordingly.
The presence of alkalinity in a water sample may be due to many different substances. However, for the sake of simplicity, the presence of bicarbonate, carbonate, and hydroxide ions is commonly considered as alkalinity. The points of change in colour of phenolphthalein and methyl orange indicators, which occur at pH 8.3 and pH 4.3 provide standard reference points which are almost universally used to express alkalinity.
Very high alkalinity values can be undesirable in an industrial water supply. For example, the presence of a high methyl orange alkalinity should be avoided in boiler feed water because of the resultant carbon dioxide content of the steam. Carbon dioxide usually is responsible for the corrosion of steam and return lines. High boiler water alkalinities are also undesirable because the presence of high hydroxide ion concentration is the primary cause of caustic metal embrittlement. A very high boiler alkalinity can also lead to an undesirable carryover condition. On the other hand, the alkalinity of boiler water must be sufficiently high to protect the boiler metal against acidic corrosion and to ensure precipitation of scale-forming salts. Usual treatment approaches include setting both a minimum alkalinity level and an operating range.
Hydroxide alkalinity may be determined by adding barium chloride prior to titration to precipitate the carbonate ion from solution, allowing direct titration of the hydroxide alkalinity. Measurement of hydroxide alkalinity is also used to control lime soda softeners.
In cooling water systems, alkalinity is of major importance since the total alkalinity of a water is one factor that must be considered when predicting the tendency for the water to precipitate calcium carbonate scale. Depending on the choice of chemical treatments to protect against corrosion and scale formation, the operating alkalinity and pH ranges are chosen to balance these two features.
Alkalinity Titrimetric Method (0-200 ppm)
Principle Theory
This test is based on the determination of alkalinity by titration with standard acid to the phenolphthalein color change (or to a pH of 8.3) and to the methyl orange color change (or a pH of 4.3). For determination of hydroxide alkalinity only, barium chloride is added prior to titration to precipitate the carbonate ions. Titration is then taken only to the phenolphthalein end point. A pH meter may be used instead of the indicators to determine the end points of the titration.
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 )
