<span style="font-size:14px;">The oxygen reducer present in RXSOL-42-5001-025 effectively binds oxygen dissolved in the make-up water, thereby protecting the equipment from corrosion. Additional protection of lines from corrosion is provided by the presence of neutralizing and film-forming amines in the product, which increase the pH of the water.</span></div>

Control is by simple  boiler water tests or <span style="font-size: 14px"><strong>RX CLEANSERS</strong></span>  can provide a suitable test  kits for this purpose.</p>
<p>
Used in low pressure and auxillary boilers</p>

<br />
<u>REAGENT & APPARATUS</u></strong> :<br />
Reagent:  RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER<br />
<br />
<strong><u>PROCEDURE for p-ALKALINITY  test ( STEP WISE )</u></strong><u>:</u></p>
<ol>
<li>
Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER</li>
<li>
Add 1-2 drops of  <strong>RXSOL TK7</strong> and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3^rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) .</li>
<li>
Add <strong>RXSOL TK9  </strong>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</li>
</ol>
<p>
RESULT  : Each DROPS is equivalent to  25 PPM of Alkalinity .<br />
<br />
NOTE :    p-Alkalinity VALUE  =  25 X ( Total Number of DROPS of TK9 , during 3^rdstep  )</p>
<p>

<p>
<strong><u>PROCEDURE for p-ALKALINITY  & TOTAL ALKALINITY ( STEP WISE )</u></strong><u>:</u></p>
<ol>
<li>
Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER</li>
<li>
Add 1-2 drops of  <strong>RXSOL TK7</strong> and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3^rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.</li>
<li>
Add <strong>RXSOL TK9  </strong>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</li>
<li>
Add 2-3 drops of <strong>RXSOL TK8</strong> and mix with stirring rod , the sample will turn to BLUISH-GREEN .</li>
<li>
Add<strong>RXSOL TK9 </strong>carefully by counting drop by drop and mixing throughly until a light reddish  pink  colour develop.</li>
</ol>
<p>
RESULT  : Each DROPS is equivalent to 25 PPM of Alkalinity .</p>
<p>
NOTE :    p-Alkalinity ppm CaCO₃VALUE ( A )  =  25 X ( Total Number of DROPS of TK9 , during 3^rdstep  )</p>
<p>
Total Alkalinity ppm CaCO₃VALUE  =  A +  { 25 X ( Total Number of DROPS of TK9 , during 5^th step  )}</p>

<p>
Optimum Result    :   p-Alkalinity  level  is between 100 to  150 PPM is suggested.<br />
<br />
 if  p-Alkalinity level is more then 150 ppm then level should be reduced by increased BLOW DOWN process with immediate effect.   </p>
<p>
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.</p>
