0.5 - 1.5 mS/cm Normal >1.5 mS/cm High Total Hardness (CaC03 - calcium carbonate such as lime and chalk) Caused by the presence of calcium and magnesium. Hard water consumes soap before a lather will form and creates scale in boilers, water heaters, and pipes. 0 - 60 mg/L soft
Nitrate contamination is rare for those who access water from a public source. Regular testing and federal regulation have led to an overall clean water supply. When contamination does occur, either from nearby farms, polluted streams, or other causes, action should be …
Sep 01, 2011 · This test is carried out to rapidly review the condition of boiler water. pH paper strip is dipped into boiler water sample, changed color of strip is compared with comparator and the pH value is obtained. This strip is same that we used in our schools. Boiler water should be slightly alkaline with its pH value lying between 8.5 ~ 9.5.
Testing Alkalinity In Boiler Water. Alkalinity is a key control parameter for boilers (outside of the prescribed operating range, it can lead to corrosion, caustic metal embrittlement, and carryover) and cooling water systems (where it has a significant effect on …
May 04, 2016 · A boiler that makes up 4000 gal/day of water having 100 ppm of hardness, has a potential of accumulating over 1000 pounds of scale per year. Alkalinity Test In natural waters, alkalinity is most commonly the result of bicarbonate and carbonate ions; in treated waters, alkalinity may also be contributed by hydroxide, phosphate, silicate, and
Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.
Boiler water tests available The specific method of chemical treatment used varies with the type of boiler and the specific properties of the water from which the boiler feed is derived. This is very site specific but we have the testing capability to cover all your requirements. A boiler requires testing of three different water types as shown

Hot Water Boiler Testing Procedures Depending how critical and how much manpower you have allocated, you should at least perform Sodium Nitrite and Conductivity testing monthly. A minimum of 800 ppm of Nitrite must be maintained in the boiler water to decrease corrosion. Testing can be performed with a sodium nitrite test kit or nitrite test strips. With the "P Indicator" boiler chemical, you may simply look at the water …
Oct 01, 1985 · Since the nitrate content of natural waters is subject to seasonal variation, it is necessary to run control tests on the boiler water for nitrate concentration, in order to insure adequate nitrate content for the inhibition of embrittlement. Another important issue in nitrate analysis in water is from a completely dif- ferent aspect.
Under normal conditions the exhaust gas from the turbine is cooled from around 550°C to 80°C. Care is taken that condensation will not occur in the cooler parts of the boiler. Nevertheless, during normal operation, dry ammonium nitrate deposits can be formed in the WHRB. These deposits will become wet when the unit is started.
The principle sources of nitrate contamination in water are thus fertilizers, animal waste, and septic tank wastes. The water supplies most vulnerable to nitrate contamination are in agricultural areas and in well waters having a close or hydraulic relationship to septic tanks. Nitrate in drinking water can be responsible for a temporary blood disorder in infants called methemoglobinemia (blue
