The control of scale is managed by specially synthesized chemicals

which inhibit scale, disperse and suspend solids. Corrosion control

are attained by using blends of organic and inorganic inhibitors and

are designed to work effectively above pH 7.5.

A range of biocide highly effective even in high water pH. All the

product are manufactured so that to ensure compliance with current

regulatory guidelines.®

Our DEWTREAT cooling water treatment program keep your

system free of corrosion and scale, and do it cost effectively. We

design our programs so that we provide best overall value for your

water treatment budget.

®DEWTRAK Data Management Software which enables plant

personnel to computerise chemical testing log sheets for fast and

easy data organisation and statistical process control and graphic

analysis. Program also exist which can model cooling system

chemistries and perform water treatment calculation.

Most up to date technology has enabled us to offer a boiler water

treatment program which covers every aspects associated with

efficient operation of steam systems.

Low molecular weight polymers disperse water hardness and

control deposits, so that to ensure a deposit free system.

Corrosion control using highly effective oxygen scavenger, pH

control and protective film formation on metal surfaces.

Complete range of neutralising and filming amines to control acid

build up due to formation of carbonic acid. Broad distribution ratio

ensures inhibitor availability at all points and affords effective

protection of the condensate return lines.

DEW offer a range of fuel oil sludge conditioner, combustion

catalyst and deposit controllers.

Dew provide one of the widest range of filteration system that

include rapid sand, multigrade, activated carbon, and Iron

removal filters.

®DEWTEX Softner are based on latest lon Exchange Technology,

standard softner model are available from 500 LPH to 50000 LPH

and custom build units for higher flow rates with automatic, semi

automatic and multiport mode of operation.

Demineralisation remove all dissolved minerals and ions from

water. There are different schemes of DM plant, depending on

quality of water. Normally two, three and four bed systems are

used. Mixed bed unit are provided for ultra clear water.

Dew manufacture a complete range of drinking and waste water

treatment plant (Urban and Industrial Waste) including Water

Clarifiers, Sludge dewatering, Diffusers, Tube settlers,

Incinerators, Flocculaters, Filters, Biofilters, Centrifuge, Floating

and Fixed Aerators.

®DEWFLOC flocculants are polyacrylamide and polymine based

polymer with high molecular weight which are water soluble and

available both in liquid and powder forms in the cationic, anionic

and non ionic types.

Reverse Osmosis chemicals

Membrane based technologies are most recent development in the

field of water treatment. Now a days membrane technology is

being used in almost all sectors of water treatment. We are

manufacturing a complete range of reverse osmosis system for

high TDS water. Desalination by reverse osmosis is one of the

most widely accepted unique process of treating brackish sea and

waste water into high purity water for their ultimate application.

Separate macro molecules and colloidal from water in the range of

1000 to 100000 dalton. Because of it larger pore size it does not

reject dissolved salts but remove silica, iron and TOC

contaminants.

Removes particles and organics in the range of 150 to 500 dalton It

is used to selectively reduce the ionic strength of solution and also

remove particles and organics.

As a leading supplier of Reverse Osmosis systems we has bridged

the gap between manufacturer and formulators with the

development of a full line of high performance membrane support

chemicals. Dew membrane support chemicals includes

Antiscalant, Membrane Cleaning and Bio-Controls chemicals.
