Innova Corporate (India) offers Thione-based biocides (2-mercaptobenzothiazole – MBT, or sodium salt) for Bawal's metalworking fluids, closed-loop water systems, and industrial lubricants used in automotive component manufacturing, engineering workshops, and steel mill maintenance. Thione compounds are effective against Pseudomonas species that form tenacious biofilms. For Bawal's engineering workshops and automotive parts manufacturers, thione-based biocides are added to cutting fluids, grinding fluids, and hydraulic oils to prevent rancidity and bacterial degradation. Typical dosage: 50-150 ppm initially, then 10-30 ppm weekly extends fluid life from 3 months to over 12 months. In closed cooling loops (chillers, diesel generator jackets, process cooling in steel mills), thione provides long-term preservation up to 80°C (176°F) and over pH 6-10. It works by chelating essential metal ions from microbial enzymes. Thione is non-foaming, non-volatile, and has very low odor. However, it can stain yellow metals (copper, brass) at high concentrations. For steel mill cooling systems with copper heat exchangers, we recommend lower dosage or use of tolyltriazole (TTZ) corrosion inhibitor. The product is available as a 40-50% active liquid dispersion and as a 98% active powder. Available in 25L, 200L drums (liquid) and 25kg bags (powder). We provide on-site microbial dip slides and plate counts to monitor fluid health. For Bawal's small engineering units, we supply thione in convenient 5L pails. Shelf life: 24 months.
Dosage in cooling water treatment programs 15 to 30 ppm for effective control of biocide activity, for cooling waters.
INNOVA BCD 505 can be fed as received or diluted with water minimum 10% concentration with any chemical feed solution. The chemical should be added to cooling tower basin (or any other point, which provides uniform mixing) addition should be made to metering pump to minimize handling.
Badly fouled systems must be cleaned before treatment to start. INITIAL DOSE - When the system is noticeably fouled, slug feed 30 to 50 ppm of INNOVA BCD 505 in the system. SUBSEQUENT DOSE - When the Microbial count is evident, slug feed 20 to 30 ppm of INNOVA BCD 505.
The best indication of the successful application of INNOVA BCD 505 is visual inspection of tower surfaces or monitoring changes in heat transfer on metal surface of process equipment.
Uses of on-site bacterial counts or microscopic examination provide relative indicators of system cleanliness and biological control. If bacteria counts are used, Note that counts may be high immediately after biocide addition. Counts will be lower as control is achieved.
INNOVA BCD 505 is available in 25Kgs, 50Kgs & 200 Kgs.
