:::::::::::::::::::::Alkalinity  TEST FOR BOILER & COOLING WATER ::::::::::::::::::::::::

REAGENT & APPARATUS

Reagent:  RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER

A.) PROCEDURE for p-ALKALINITY  test ( STEP WISE )

1

Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER

2

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 3rdstep otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) .

3

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 p-Alkalinity.

NOTE

p-Alkalinity VALUE  =  25 X ( Total Number of DROPS of TK9 , during 3rdstep  )

B.) PROCEDURE for m-ALKALINITY  test ( STEP WISE )
1.1 >> Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
1.2 >> Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
1.3 >> AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish (salmon) pink  colour develop.
RESULT  : Each DROPS is equivalent to  25 PPM of m- Alkalinity
m-Alkalinity VALUE = 25 X ( Total Number of DROPS of TK9 , during 1.3 step  )
 

C.) PROCEDURE for TOTAL ALKALINITY ( VALUE of A + VALUE of B )

2.1

Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER

2.2

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 3rdstep otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.

2.3

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

2.4

Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .

2.5

AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish ( salmon ) pink  colour develop.

RESULT

Each DROPS is equivalent to 25 PPM of Alkalinity

NOTE

p-Alkalinity ppm CaCO3VALUE   =  25 X ( Total Number of DROPS of TK9 , during 2.3 step  )  = X ( Say )
m-Alkalinity ppm CaCO3VALUE  =  25 X ( Total Number of DROPS of TK9 , during 2.5 step  )  = Y ( Say )
Total Alkalinity ppm CaCO3VALUE  =  X+Y

Optimum Result    :   p-Alkalinity  level  is between 100 to  150 PPM is suggested.

if  p-Alkalinity level is more then 150 ppm then level should be reduced by increased BLOW DOWN process with immediate effect.  

For Below  50 ppm  , Dose ½ Ltrs of RXSOL-50-5001-BWT for 1000 Ltrs of  BOILER WATER , to maintain p-Alkalinity level 100 ppm.
