Water Boiler Control & Cooling Towers - Wastewater Treatment
Boiler Control & Cooling Towers: Its Water quality parameters & Treatment
Deposits and corrosion are the two major wastewater related problems boilers control and cooling towers face. As boiler or water evaporation generates steam by cooling towers, dissolved particles and minerals are left behind increasing the concentration of these minerals. Minerals are also introduced through the water added to makeup the water lost to steam or evaporation. Eventually, the minerals reach a level of concentration that will cause loss of efficiency either due to scale or damage from corrosion. Most people recognize problems associated with corrosion. However, effects from scale deposits are also equally important.
In an effort to control these problems numerous wastewater treatment methods are employed. Even with wastewater treatment, it’s still necessary to regularly blow down or bleed off part of the concentrated water and make up with lower saline water to reduce the overall mineral concentration. To conserve water and treatment chemicals, it is required to allow the dissolved minerals to reach a maximum cycle of concentration while still avoiding problems. Because feed water or make-up waters vary in the types and amounts of minerals present, the allowable cycles of concentration will also vary. As a result, regular testing of boiler control and cooling tower waters is essential to optimize water treatment systems. Tests commonly performed analyze the TDS or conductivity, pH and ORP.

What are the Water quality parameters Tested for Boiler Control and Cooling Tower Waters?
Usually boiler controls and cooling towers have an in-line controller that is used to release water from the tower or boiler and feed chemical into the system. To ensure fouling or drift of the sensor has not occurred, the controlled must be attuned regularly. However, the following water quality parameters are tested for Boiler Control and Cooling Tower Waters.
The measurement of a solution's ability to transmit electric current is called conductivity. Pure water is a poor electrical conductor. Conductivity is determined by the amount of ionized substances or salts dissolved in water. As, majority of dissolved minerals in water are these conductive inorganic impurities, conductivity measurement is a best indicator of mineral concentration.
pH is the measurement of acidity or basicity in water. This is one of the most important factors affecting scale formation and corrosion in a boiler or tower cooling system. The types of impurities comprising the mineral concentration behave differently at various pH levels. Water with low pH level has a tendency to cause corrosion, while water with high pH levels may cause scale formation.
Requirements of boiler water can vary from very pure to more than 6500 micro Siemens. This will depend on size, pressure, application, and feed water. Once the maximum cycles of concentration has been established, a conductivity instrument can conveniently help you to determine if the blow down schedule is adequate. Samples should be cooled to at least 160°F or 71°C to ensure accurate temperature compensated readings.
Boiler condensate samples are often tested to determine if there are any carryover of boiler water solids or contaminants entering from outside the system. Condensate is relatively pure water, and values of 2-to100 micro Siemens are not uncommon. Because of these low values, a multiple range instrument is suggested to increase the resolution and accuracy of the reading. Monitoring pH levels of condensate is also important since condensate is very corrosive at low pH levels. Treatment additives are often added to increase the level of pH to minimize corrosion in condensate lines.
Since the reduced use of acid and the elimination of chromate, cooling tower water has become more challenging. to maintain a proper wastewater treatment program monitoring conductivity and pH has become imperative. Though many systems have controls on these water quality parameters, the possibility of a system downtime is always present. Even slight downtime period can cause rapid scaling of heat exchangers.
Another extremely important facet to proper cooling wastewater management is biological growth. Microbes can cause corrosion, fouling, and disease. Oxidizing biocides (chlorine, chlorine dioxide, ozone and bromine) have been employed to keep bacteria under control. Monitoring of the ORP (Oxidation Reduction Potential)/REDOX is very useful in its ability to correlate millivolt readings to sanitization strength of the water.
Wastewater Treatment in Boiler Control
Boiler control water treatment is a type of industrial wastewater treatment that is primarily focused on removal or chemical modification of matter that can potentially damage the boiler. Different types if wastewater treatment is administered at different locations to avoid scale, corrosion or foaming. External wastewater treatment of raw water supplies intended for use within a boiler is focused on removal of impurities before they reach the boiler. Internal treatment within the boiler is mainly focused on limiting the tendency of water to dissolve the boiler, and impurities in forms least likely to cause trouble before they can be eliminated from the boiler.
Wastewater Treatment in Cooling Towers
Besides treating the circulating cooling water in large industrial cooling tower systems to minimize scaling and fouling, the water should be filtered to remove particulates. Water should also be dosed with biocides and algaecides to prevent growths that could interfere with the continuous flow of the water. Under certain conditions, a biofilm of microorganisms such as fungi, bacteria, and algae can grow very rapidly in the cooling water, and can reduce the heat transfer competency of the cooling tower. Chlorine or other chemicals can be used to reduce or prevent Biofilm.
