Atish Chemicals

In Cooling Tower often it is seen that scale of Calcium Carbonate, Magnessium Carbonate, Silica ,
Sulphate,Phosphate scales block the heat transfer area. The same is observed in different types of Heat
Exchangers, Pipes carring hard water. For cooling tower & Condenser it is difficult to remove the scale with the
help of Acid because the acid may corrode copper tubes.
We have developed a new product AT-TREAT-901 (ORGANIC DESCALANT) in liquid
form to remove scales deposited on the wall of heat exchanger. AT-TREAT-901 removes not only
the scales but protect copper, Alluminium from corrosion. It is organic formulation of Polymers,
Chelating Agents, Glycol, Azole basd corrosion inhibitor.
Product Specifications:
• Colour: Clear To Slight Amber colour Liquid.
• PH
• Solubility: Completely soluble in water.
• Solids: 50-60%
Application:
Quantity of AT-TREAT-901 for Descaling depends upon scale concentration. One can circulate the
solution with help of electric pump for 7-8 Hrs. If thin layer of scale are arrond pipe wall, we
recommend to circulate the solution (1:3 with D.M. WATER) for atleast 7-8 Hrs.( After dilution.with
water). Before circulation disconnect from original source of water. If the scale are very hard and
thick we recommend not to dilute or dilute 1: 1 with water depending upon scale concentration. .
After circulation for 7-8 Hrs flush with clean water and connect to original source of water.
Can be used to descale Solar Pipes, Cooling Tower, Boiler Tubes descaling Any kind of Heat
Exchanger.

Cooling Tower Antiscalant

Cooling Water Antiscalants or Scale Inhibitors are chemical compounds that inhibit or prevent scale formation in the heat exchanger by means of sequestering calcium and magnesium salts, dispersing silica, chelating iron and breaking-up colloidal deposits like clay and silt that are otherwise formed in the heat exchanger.

Antiscalants that are effective are profitable for users for its round the year savings of power and labor, and increase in production. Use of anti-scalant is a prime necessity to meet up with the huge production targets.

ATISH CHEMICALS range of Cooling Tower Antiscalants is effective on untreated hard water with high pH range, TDS, alkalinity, Iron and Silica content.

It also content Corrosion Inhibitor for Copper, Steel, Aluminium etc.

Application: Cooling Towers, Air Washers, Evaporative Condensers, Cooling Water Heat Exchangers, Radiators, Gear Boxes, Injection Mouling Machines, Blow Mouling Machines, Housings, D.G.Sets etc.
Chemical Type
Organic Chemical Compound
Form
Liquid
Specific Gravity
Ranges from 1.1 - 1.2 depending upon product
pH
Ranges from 5 - 7 depending upon product
Solubility
Completely Soluble in Water

Dosage: Cooling Water Antiscalants are normally fed continuously to the re-circulating water. It can be injected by chemical dosing pump or fed directly to the CT sump (basin). The amount of antiscalant required to inhibit scale formation depends on the quality of feed water and plant operating conditions. The specific dosage rates will be specified by the our technical representative.

Offering Descaling Chemical For Solar Water Heater./ heat exchanger
Water contains various metallic salts in suspension. These metallic salts get accumulated inside pipelines, tubes, etc. in the form of scales over a period of time. These scales must be removed periodically in order to restore the efficiency of system, reduce heating time and attain the required temperature.
 
AT-TREAT-901   has been formulated mainly for descaling Solar Water Heating System. It is an inhibited acidic composition containing surface active agents and cleaning agents to effectively dissolve and remove all water scale deposits from Copper, Brass, M.S., S.S. and Aluminum tubes, Pipelines and Vessels. Descaling with AT-TREAT-901   is safe, simple and economical.
 
Descaling Procedure:
1.    Descaling of Solar Plate Tubes along with Storage Tank by CIRCULATION METHOD:
1.    Prepare a 2-3 times  solution of AT-TREAT-901   v/v (volume by volume) with water in a 50 to 100 litres capacity open top circulating tank. (Say 1 Litre AT-TREAT-901  AND 3 Litre water). Tank must be made of either Plastic, S.S. or FRP/PVC lined M.S. tank.
1.    Connect the outlet of this open top circulating tank by a rubber/plastic hose to the inlet of a 1 or 2 HP S.S./Plastic pump. The outlet of pump should be connected by hose to the drain valve of solar plate. Connect the outlet of the storage tank by hose back to the circulating tank.
1.    Start the pump and completely fill the system with AT-TREAT-901   by circulating the same for 3-4 hours preferably at 45°C.
1.    Discard AT-TREAT-901   solution and then completely flush the system with plenty of water by circulation till the pH of water reaches 6-7.
1.    Descaling of Solar Plate Tubes only without Storage Tank by CIRCULATION Method
 

Bio-Dispersant available in Non ionic & Anionic base effectively cleans and disperse heavily fouled Cooling Water Systems. Fouling by microbiological slimes is reducing overall system efficiency.bio dispersant is the powerful and concentrated product to remove and disperse the unwanted deposits, Which is resulting in water clarity.

Bio dispersant/ Bio detergent Chemical
AT-TREAT-801 is chemical that can penetrate, and loosen the complex matrix of Biofilms allows biocides to reach the organism for more effective kill & control. These chemicals are typically shot fed at dossage that break down poly-saccharides, emulsifying oil, realease mineral & foulants or disperse biopolymers.
It is used in water system for removing or preventing bio films. The micro organism vary differently within a bio film then when the same species are floating freely. In water treatment bio films are undesirable because harbor pathogenic organisms such as Legiomella, they reduces heat transfer, they causes increased friction or complete blockage pipe. They foul proves and they contribute to corrosion.
In terms of corrosion to the system metal bio films contributes to MIC(Microbiological Induces Corrosion)In addition to bio films allows accumulation to most acidic metabolic products near the metal surface, which accelerates the cathodic reaction.
It is effective at pH range 3-8.
Dosage
Under most conditions we recommend that AT-TREAT-801 be used at 50-100 ppm. The recommended method of application is either drip or sloe pump feed, 1-3 times per week in a clean system. In fouled system the dosage of 50 ppm everyday until the bio film is removed. It is not recommended that other micro biocides be fed during the cleaning stage.
Packing
AT-TREAT-801 is available in 35 kg and 50 kg HDPE Carboy.

Used in cooling tower for control of scale formation as well as stop corrosion

Atish Chemicals cooling tower water treatment products employ the latest technology to ensure that your cooling towers operate efficiently and reliably with relatively low monitoring and maintenance requirements. Atish chemicals primary cooling tower water treatment products are multifunctional blends of corrosion inhibitors, dispersant and anti-scaling polymers, sequestrates, pH buffering compounds and algae control agents. Under normal operating conditions primary treatment will be all that is required to maintain your system parameters in proper control ranges.

However, Atish Chemicals offers supplemental products to deal with special situations and to clean and treat closed water systems, which are often associated with cooling towers.

For example, we have products to increase anti-scaling protection for situations in which make-up water contains very high hardness levels and products to boost algicidal/biocidal power.

A complete listing of Atish chemicals cooling tower and closed system treatments are given below.
