Innova Corporate (India) offers Thione-based biocides (2-mercaptobenzothiazole – MBT, or sodium salt) for Assam's metalworking fluids, closed-loop water systems, and industrial lubricants used in tea garden machinery (CTC rollers, withering fans), paper mill equipment, and refinery pumps. Thione compounds are effective against Pseudomonas species that form tenacious biofilms. For Assam's tea gardens with machinery maintenance workshops, thione-based biocides are added to cutting fluids, hydraulic oils, and gear lubricants 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 in tea processing, diesel generator jackets in refineries), 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 tea garden equipment with copper parts, we recommend lower dosage or use of tolyltriazole (TTZ) corrosion inhibitor. For paper mills and refineries, thione preserves closed cooling loops during seasonal shutdowns. The product is available as a 40-50% active liquid dispersion and as a 98% active powder. The liquid form is easier to dose. Available in 25L, 200L drums (liquid) and 25kg bags (powder). We provide on-site microbial dip slides and plate counts to monitor metalworking fluid health for Assam's tea garden workshops. For small tea gardens, we offer 5L pails with simple dosing instructions. 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.
