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

Chemical feed should be continuous. Chemical pumping rates can create problems especially for neat feed set ups. Using on/off feed systems such as a recycle timer can create problems. Chemical feed pumps should be sized or product strengths should be adjusted to allow continuous feed.

Steam and carbon dioxide leave continuously, so setting up a neutralizing amine pump to feed intermittently can lead to wide variations in condensate pH control. If sampling is done from a condensate receiver, the tank volume may buffer the variations and the changes may not be noticed, but corrosion could be occurring to areas of the piping that see the rapidly changing pH.


If polymeric dispersants, phosphonates, phosphate, or chelants are fed intermittently into the feedwater using a recycle timer, and the amines are not fed continuously, a cycle of iron slugs returning in the condensate can be followed by slugs of high dispersancy cleaning of the iron from the deaerator and dragging it into the boiler.

Load changes can affect chemical concentrations when the chemical feed is base fed. Example: Steam production of one million lbs./day; 4% blowdown; 20% active boiler polymer product fed at 5 pounds per day. The calculated daily average polymer concentration would be 24 ppm. Assume peak plant production load is 60,000 lbs./hr., but during the overnight hours the load is only 5,000 lbs./hr. If the dispersant is being fed continuously over the 24 hours, during the 8- hour low load period, the boiler polymer concentration would have increased to over 200 ppm. Upon high fire when production resumes, carryover is very possible because of over concentrating the polymeric dispersant.

Chemical feed needs to be paced to steam production, especially where significant load changes occur.

Carbon dioxide can concentrate in steam and condensate making neutralizing amine treatment impractical. Carbon dioxide levels can be relatively low in steam exiting a boiler at only a few ppm, but if there are areas where it becomes “trapped” and can accumulate, concentrations can reach extremely high levels into the hundreds or even thousands of ppm.

CO2 is a non-condensable gas. It has a distribution ratio in the steam piping and condenses at points throughout the system. At the boiling point, the solubility of the gas in water is extremely low. The solubility of the CO2 is actually lower in the condensate than it is in the steam. For the CO2 to escape from the steam into the water it will accumulate in the steam space just above the water level until the partial pressure becomes high enough for the CO2 in the incoming steam to be able to exit into the condensate. This creates a steady state condition of CO2 coming in and exiting, but an area of severe localized corrosion occurs where the carbon dioxide concentration is high.

The highest CO2 concentration normally occurs just above the condensate water level. If there is an area where condensation is occurring and running down pipes or the sides of vessels, the CO2 concentration will be very high and the pH will be about 5.3 – 5.5 in that location creating high corrosion rates.


The solubility of CO2 increases dramatically as the condensate temperature falls below 212 °F. When there is an accumulation of CO2 in an area and the condensate temperature is relatively low, the amount of carbon dioxide going into solution will be extremely high. Where low-pressure steam is used that contains CO2 and the heat exchange process has relatively close temperature differentials between the steam and the condensate, there is potential for high uptake of the CO2 into the condensate and localized low pH.

Neutralizing amines are selected in an effort to condense in the right concentrations to carbon dioxide condensation levels throughout the steam system. Neutralizing amines cannot control corrosion where this localized accumulation of carbon dioxide occurs since the high CO2 overwhelms the demand for the amine. Even point source addition of amine may not be able to satisfy the demand.

Where the concentrating effect of CO2 occurs, methods of reducing the problem include eliminating or minimizing CO2 in the steam, venting off the CO2 in the localized area, eliminating condensate in the area, applying a filming amine or metal passivator, or using higher temperature steam and increasing condensate temperature to reduce the CO2 content in the condensate.

Before testing of Nitrite level, Here is some point and guideline,  what you need to do. : 1 take the following readings; pH, TDS (uS), and nitrite level.and record. 2 add the Chemical your are using. 3. wait for a period of time for the sysem to circulate. hours> 4. Re check the readings. and record. 5 track these readings
for a period of time.

If the TDS and Nitrite drop you have a leak/ unknown makeup. if the TDS stays stable and the nitrite drops you have a biological problem. Bacteria that convert nitrite to nitrate.

Solution ::: Use DI water in place of general water, And also use. Algaecide to control Bacterial growth inside water system ... http://rxmarine.com/Biocide-Algaecide

ALUMINIUM SULFATE Al2(SO4)3

Aluminum sulfate is a water-soluble white crystalline solid compound with the chemical formula Al2(SO4)3. Aluminium Sulfate is a coagulating agent in the purification of drinking water and wastewater treatment plants,  pH regulation of garden soil, and other commercial or industrial applications like paper manufacturing, in firefighting foams, and in sewage treatment and water purification.

Aluminum Sulfate Anhydrous is an aluminium salt adsorbs and precipitates protein antigens in solution.It is primarily used as a coagulating agent in minor cuts and abrasions.

ALUMINIUM SULFATE manufacturer and supplier in Mumbai, Kandla, Chennai Ennore, Visakhapatnam, Kolkata, Fujairah - Dubai, Sharjah, Ajman, Abudhabi, UAE Gulf, Muscat RUWI, Oman, Barka, Sudan, Yemen, Nairobi Kenya

Aluminium Sulfate is used as coagulant to remove almost any kind of impurities in water. Its main function is to provide electrically charged ions capable to neutralize effectively the electric charges of the colloid material present in the water, thus allowing them to come together. The alum reacts rapidly with the water alkalinities. This produces a gelatinous precipitate of aluminum hydroxide that entraps and absorbs impurities.

Sampling And Testing

A sample of boiler water should be drawn for analysis daily. The sample should always be taken from the same point after blow down, cooled and tested immediately. Follow the Rxsol Hardness Test Kit instructions and fill the Boiler Water Log Form according to result results. It is important that regular testing is carried out to ensure levels of treatment are correct.
