One Shot Universal Liquitreat 100
Boiler Water treatment specialized is a well - balanced blend for boiler water treatment products, Resulting in a scale and corrosion control by one shot operation. A one-step treatment to control the formation of rust and scale in low pressure and auxillary boilers with working pressure up to 20 bars.
The stability of the added polymers are very useful for water treatment processes. Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide.
The dosage rate is dependent on bioler operating condition, feed 2-3 ltrs of RXSOL-50-5001-025 solution for per thousand ltr of bioler water then control the system by periodic Alkalinity test procedure. If p-Alkalinity is below 200 ppm increase the ratio of RXSOL BWT 5001 solution. If p-Alkalinity is above 400 ppm reduce the concentration of RXSOL-50-5001-025 solution by dilution with water. RXSOL-50-5001-025 is strongly alkaline.RXSOL-50-5001-025 is best applied heat or diluted with any convenient strength on a continuous basis using a suitable chemicals pump. The product should be applied to the boiler feed tank or feed line to ensure adequate mixing.
Control is by simple boiler water tests or RX CLEANSERS can provide a suitable test kits for this purpose.
Used in low pressure and auxillary boilers
:::::::::::::::::::::Alkalinity TEST FOR BOILER & COOLING WATER ::::::::::::::::::::::::
REAGENT & APPARATUS :
Reagent: RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER
PROCEDURE for p-ALKALINITY test ( STEP WISE ):
- Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
- Add 1-2 drops of RXSOL TK7 and mix with the stirring rod , If sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) .
- Add RXSOL TK9 drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 25 ppm of p-Alkalinity , expressed as CaCO3
RESULT : Each DROPS is equivalent to 25 PPM of Alkalinity .
NOTE : p-Alkalinity VALUE = 25 X ( Total Number of DROPS of TK9 , during 3rdstep )
PROCEDURE for p-ALKALINITY & TOTAL ALKALINITY ( STEP WISE ):
- Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
- Add 1-2 drops of RXSOL TK7 and mix with the stirring rod , If sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.
- Add RXSOL TK9 drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 15 ppm of p-Alkalinity , expressed as CaCO3
- Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
- AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish pink colour develop.
RESULT : Each DROPS is equivalent to 25 PPM of Alkalinity .
NOTE : p-Alkalinity ppm CaCO3VALUE ( A ) = 25 X ( Total Number of DROPS of TK9 , during 3rdstep )
Total Alkalinity ppm CaCO3VALUE = A + { 25 X ( Total Number of DROPS of TK9 , during 5th step )}

Optimum Result : p-Alkalinity level is between 100 to 150 PPM is suggested. For Below 50 ppm , Dose ½ Ltrs of RXSOL-50-5001-025 for 1000 Ltrs of BOILER WATER , to maintain p-Alkalinity level 100 ppm.

Below is a summary of problems associated with the common impurities in water and solutions to each problem.
List Of Problems Caused By Impurities In Water
|
Impurity (Chemical Formula) |
Problems |
Common Chemical Treatment Methods |
|
Alkalinity (HCO3-, CO32- and CaCO3) |
Carryover of feedwater into steam, produce CO2 in steam leading to formation of carbonic acid (acid attack) |
Neutralizing amines, filming amines, combination of both, and lime-soda. |
|
Hardness (calcium and magnesium salts, CaCO3) |
Primary source of scale in heat exchange equipment |
Lime softening, phosphate, chelates and polymers |
|
Iron (Fe3+ and Fe2+) |
Causes boiler and water line deposits |
Phosphate, chelates and polymers |
|
Oxygen (O2) |
Corrosion of water lines, boiler, return lines, heat exchanger equipments, etc. (oxygen attack) |
Oxygen scavengers, filming amines and deaeration |
|
pH |
Corrosion occurs when pH drops below 8.5 |
pH can be lowered by addition of acids and increased by addition of alkalies |
