Water Treatment Biocides


Water Treatment Microbicide                                                   Email:sales@ozziechemical.com

Chemical Name: chloromethylisothiazolinone/methylisothiazolinone

CAS No: 26172-55-4/2682-20-4


CMIT/MIT-14 PLUS microbicides are high performance, broad spectrum, antimicrobial agents based on the proven isothiazolone chemistry of Ozzie Company.

They are effective at very low concentrations in controlling both the planktonic and surface growth of bacteria, fungi and algae and have been produced specifically for water treatment and paper mill applications.Ozzie Company have developed an unrivalled package of regulatory approvals and environmental fate, toxicology, and performance data to support the use of CMIT/MIT-14 PLUS in water treatment applications.

The only difference with CMIT/MIT-14

CMIT/MIT-14 PLUS can be directly diluted with water; no stabilizer is needed.

Rapid inhibition of growth and macromolecular synthesis

CMIT/MIT-14 PLUS causes immediate inhibition of growth on coming in contact with a microorganism.

Broad spectrum activity

CMIT/MIT-14 PLUS controls the wide variety of algae, bacteria and fungi found in industrial water systems. Such a broad spectrum product reduces inventory and handling costs, lowers operator training expenses and lessens the risk of dosing error.

Effective at low concentrations

Effective control of such a wide variety of microorganisms at levels as low as 1 ppm active ingredient by CMIT/MIT-14 PLUS provides an unrivalled and cost-effective treatment.

Effective against biofilm

CMIT/MIT-14 PLUS  readily penetrates the surface of adhering biofilm to give effective control of sessile microorganisms.


CMIT/MIT-14 PLUS  is compatible with chlorine, corrosion and scale inhibitors and most anionic, cationic and non-ionic formulations at normal use levels.

Non-surface active: CMIT/MIT-14 PLUS is non-foaming.

Infrequent dosing: CMIT/MIT-14 PLUS  remains active for long periods of time in the water system, resulting in low service costs.

Easily deactivated: Spills of the concentrated active components of CMIT/MIT-14 PLUS  are readily deactivated to non-toxic substances by the addition of a slightly acidic solution of sodium metabisulphite or sodium bisulphite.

Application Areas

CMIT/MIT-14 PLUS  is ideally suited to meet the requirements of an industrial water treatment biocide. CMIT/MIT-14 PLUS microbicide is not deactivated by suspended organic matter, and is compatible with other water treatment additives, including chlorine. With the recent change of many cooling towers and paper mills to alkaline operating conditions, it is important to use a biocide such as CMIT/MIT-14 PLUS which remains stable at higher pH values. CMIT/MIT-14 PLUS  is of low toxicity at use levels, easily deactivated and biodegradable. In addition to all these.
