COOLING TOWER CHEMICALS


The principal of a cooling tower is to cool the water that has picked up heat generated by Heat exchanger. Scale caused by precipitation of compounds that become insoluble at high temperatures, such as calcium carbonate. Scale interferes with heat transfer and reduces flow. Corrosion is a function of water characteristics and the metals in the system. Corrosion causes premature metal failures: deposits of corrosion products reduce both heat transfer and flow rates. Fouling results from the settling of suspended solids, build up of corrosion products, and growth of microbial masses. Fouling has the same effect on the system as scaling, but fouling also promotes severe corrosion under deposits

Scale Inhibitors

The accumulation of scales is a significant issue affecting the operation and maintenance of industrial boiler systems and steam plant. Scale is caused by the accumulation of hardness salts in the boiler water. They are treated inside the boiler itself with scale inhibitors.

Corrosion Inhibitors

Corrosion inhibitors decrease the corrosion rate of a material, typically a metal or an alloy. The effectiveness of a corrosion inhibitor depends on fluid composition, quantity of water, and flow regime. They form a protective layer on the material's surface, preventing further degradation.

Biocides

Biological products intended to prevent damage to human health or property. Due to these properties, pesticides and biocides may cause harm to health and the environment. That is why pesticides and biocides need authorisation and must be used properly.

RO Mebrane Treatment

Scaling elements like calcium carbonate, calcium sulphate, barium sulphate, strontium sulphate, silica, iron and alumina etc. reduce the filterability of RO system & hinders the water flow. Inadequate service program of membrane elements/system can face early degradation and poor performance. This results fouling, scaling and premature membrane deterioration. Consequently, this reduces throughput and calls for unwanted downtime and membrane cleaning.

Antiscalant is a pretreatment water additive for reverse osmosis systems that is highly effective in preventing membranes from scaling. Before the feed water enters the reverse osmosis membrane, an antiscalant is injected into the water and sent through the system.

RO Cleaning chemicals

Cleaning of membranes is vital because contaminants can build up on the surface of membrane which will reduce the product flow and can affect the quality of permeate. Cleaning should be carried out when, a. Product flow drops 15% below rated flow at rated operating pressure. b. Permeate TDS increases by 25%. c. The pressure difference across the feed and the reject has increased by 15%.

Membrane Biocides

Reverse osmosis systems are favourable environments for microorganisms to thrive. Kimberlite products are non-oxidizing biocides that are highly effective in reducing bacterial growth and the build-up of slime on a variety of membrane types.

Boiler Water Treatment

The concept of employing water, fresh or distilled, as a power generating source and heat exchange medium originated and was realised with the inception of the steam generator or boiler, and has been applied most successfully and beneficially in this manner ever since.

Antiscalants

Deposits particularly scale can form on boiler tubes - as the equilibrium conditions in the water contacting these surfaces are upset by an external force, such as heat. Each impurities/contaminant has an established solubility in water and will precipitate when it has been exceeded. If the water is in contact with a hot surface and the solubility of contaminant is lower at higher temperature, the precipitate will form on the surface, causing scale. The most common boiler deposits are calcium phosphate, calcium carbonate, Magnesium hydroxide, magnesium silicates, various form of iron oxides etc.

Oxygen Scavenger

The second major water related boiler problem is corrosion, the most common example being the attack of steel by oxygen. This occurs in water supply systems, pre boiler systems, boilers, condensate return lines and in virtually any portion of the steam cycle where oxygen is present. Oxygen attack is accelerated by high temperature and low pH. A less prevalent type of corrosion is alkali attack, which may occur in high pressure boilers where caustic can concentrate in a local area of steam bubble formation because of formation of porous deposits.

PH Booster

A very effectual chemical used to improve the pH of the process water. It also efficiently decreases the bacterial action which drops down the pH. This chemical is processed using high quality chemical substances for spraying ponds. Further, this Spray Pond Water pH Booster also maintains the pH level of the water to +7 and prevents the bad odor.
