One of the most serious aspects of oxygen corrosion is that it occurs as pitting. This type of corrosion can produce failures even though only a relatively small amount of metal has been lost and the overall corrosion rate is relatively low. The degree of pitting depends on the concentration of dissolved oxygen, the pH and the temperature of the water.

Oxygen pitting occurs in boiler tubes, and turbine blades. It is also the reason for failure of steam lines, and fittings etc. as well as the root cause of unscheduled shut downs. HI TECH BOI CHEM Systems can recommend the correct chemical treatment through oxygen scavengers which remove oxygen instantly and control pitting.

Corrosion

Corrosion is a significant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen. Corrosion may occur in the feed-water system as a result of low pH water and the presence of dissolved oxygen and carbon dioxide. Corrosion leads to boiler piping becoming weak and leading to leakage problems.

Scaling

Scaling occurs due to impurities being precipitated out of the water directly on heat transfer surfaces or due to suspended matter in water. Evaporation in a boiler causes impurities to concentrate. Common feed water contaminants that can form boiler deposits include Calcium, Magnesium, Iron, Aluminum and Silica. Scale is formed by salts that have limited solubility but are not totally insoluble in boiler water. These salts reach the deposit site in a soluble form and precipitate.

Scaling leads to loss of heat transfer efficiency and often, acts as an insulator. In the long run, it can lead to severe problems such as rupturing of tubes and aiding of corrosion. In general, boiler deposits can cut operating efficiency, damage equipment, lead to unscheduled boiler outages and increased cleaning expenses. Scaling can also impact fuel consumption and power cost of steam generation.

HI TECH BOI CHEM uses different types of antiscalants to treat boiler scaling problems and minimize the damage based on an in-depth chemical analysis of the feed water.

Foaming

Foaming is a condition that occurs in boilers when there are high concentrations of soluble salts, suspended solids or organic matter. These create foam in the steam space of boiler that adversely impacts the quality of steam produced.
De-foaming and anti-foaming chemical treatments are used selectively to treat this problem.

Sludge

During the operation of a steam boiler small quantities of hardness salts are introduced, together with traces of suspended matter into the feed-water. Over time the concentrations of these salts and suspended matter build up, in the form of a 'sludge', and if not treated properly can settle on to heat transfer surfaces, eventually 'baking' on to form a hard crystalline scale.

Cooling Towers drive away heat from re-circulating water that is passed through chillers, air-conditioning equipment, or other process equipment. Proper treatment of the water that circulates through the tower is critical in determining the heat transfer efficiency and increased life of the cooling tower and associated process equipment.

Major problems with cooling tower systems resulting from improper water treatment include:

• Corrosion
• Microbiological Fouling
• Hardness scaling
• Silica scaling

Corrosion

Generally, higher water temperature promotes scaling and rapid corrosion. Further, continued presence of oxygen corrodes mild steel and other metals. Due to corrosion the lifespan of the entire metallic piping and equipment parts decreases and often leads to unplanned shutdown.
HI TECH BOI CHEM Systems offers a suitable type of corrosion inhibitors to control rate of corrosion after due analysis of the water quality and dosage requirements.

Microbiological Fouling

Improper disinfection of make-up water in cooling tower systems can lead to contamination with micro-organisms like various types of bacteria, algae etc. Also, due to the scrubbing action of cooling towers, micro organisms, dirt and sediment get introduced in the system. Microbiological fouling can cause the entire PVC or HDPE fins to be replaced completely.

Normally, oxidizing base and non-oxidizing base biocides are widely used for disinfection application. HI TECH BOI CHEM recommends the proper dosage of disinfectants to be maintained to control microbiological growth as well as special cleaning reagents for cleaning of PVC/HDPE fins to improve heat transfer efficiency.

Scaling

Hard water in the system produces scaling which is primarily caused by calcium and magnesium salts. The other type of scaling occurs as a result of silicates in the water. Make up water further increases scaling tendency. Scaling directly impacts the heat transfer efficiency of the entire system. This further loads the system with additional power requirement of up to 10-15%.
Cleaning with specialty cleaning reagents may also help to identify the type of scalant. To find out root cause of the scaling,
HI TECH recommends an analysis of the feed water for levels of calcium, magnesium, Hydroxides, Carbonate, Bicarbonates, chloride, fluoride, silicate, & pH.

Based on above analysis, specific Antiscalant, Oxidizing & Non Oxidizing Biocides, Polymers, Biodispersant Agents are administered to take care of complete cooling tower operations.

Effluent is the wastewater released by businesses and industries in a community. In effluent percent water, with only 0.06 percent of the wastewater dissolved
and suspended solid material. The cloudiness of sewage is caused by suspended particles which in untreated sewage range from 100 to 350 mg/l. Sewage also contains nutrients (such as ammonia and phosphorus), minerals, and metals. Ammonia can range from 12 to 50 mg/l and phosphorus can range from 6 to 20 mg/l in untreated sewage.
Effluent is the waste from various departments from Industries. Sometime, Effluent disposal and recycling is become major issue for Industrial.
There is lot debris which comes through our waste stream. Things like rags, sand, gravel and larger pieces of organic matter must be removed before it enters our Treatment System.
Now, almost all Industries had there own Effluent Treatment Plants to treat Effluent water for recycling purpose and for Disposal applications. Effluent needs Proper Chemical Treatment Program. Problems occurred in ETP mainly because of untreated Effluent water and improper operation of the system. It causes major Problems with ETP like:

• Foam Formation

Reverse Osmosis (RO) – a proven technology for achieving the finest level of filtration is preferred across pharmaceutical and biotech industries for production of purified water.
Untreated feed water and improper operation of the system can lead to several problems such as:

• Hardness scaling
• Silica scaling
• Microbiological Fouling
• Oxidation

Scaling

Scaling of RO membranes directly impacts performance of the entire RO system. Due to scaling, RO permeate water flow rate decreases drastically with increase in operating pressures. Scaling also deteriorates permeate water quality.
HI TECH BOI CHEM Systems offers a wide range of antiscalants to resolve such problems. These can be carefully selected based on feed water analysis. Using the correct antiscalant with the correct dosage will keep the membranes scale free and will improve permeate water quality and decrease operating pressure thereby saving power costs. s

Microbiological Fouling

In many cases, RO systems get contaminated with micro-organisms like various types of pathogens due to improper disinfection of raw water. It is very difficult to eliminate microbiological contamination from RO systems. Microbial Fouling causes reduced permeate flow and poorer permeate water quality. Timely and correct treatment can control and eliminate microbiological problems and the need to replace RO membranes.
In pre-treatment, disinfection of raw water is very important. Normally, chlorine base or ozone base oxidizing treatments are widely used for disinfection. However, it is very important that before passing the water into RO system, it must be free from any oxidizing matter.
HI TECH BOI CHEM Systems has a proven Chemical Sterilizer which controls Microbiological Contamination.

Oxidation

Presence of residual chlorine, ozone or any oxidizing matter in feed water will oxidize RO membrane. As a result, water quality deteriorates. In case of oxidization of RO membrane, replacement is the only solution.
This problem can be controlled by deoxidizing the water by using anti-oxidizing reagents before entry into the RO Systems.

HI TECH BOI CHEM Systems’ comprehensive range of RO System Solutions can lead to the following benefits:

• Proper cleaning program will increase the life of RO membranes by 30 - 50% and save power up to 10%.
