Innova Corporate (India) introduces our specialized Biocides for Severe Fouling, a powerful formulation engineered for the most challenging industrial water conditions in the Kingdom of Saudi Arabia. Facilities across Jubail, Yanbu, Riyadh, Dammam, and Jeddah often encounter extreme biological fouling due to high nutrient loads from process leaks (oil & gas hydrocarbons, petrochemical solvents, organic compounds, food processing waste), warm temperatures (cooling water return at 45-55°C in summer), extremely high TDS (5000-20000+ ppm), high salinity, and aged piping with existing biofilm deposits (decades of fouling in older plants). Standard biocide programs often fail under these conditions, leading to reduced heat transfer (10-25% loss), increased pump energy (15-30% higher), accelerated corrosion under deposits (pitting, MIC - microbiologically influenced corrosion), and frequent system shutdowns for cleaning (every 2-4 weeks in severe cases). Our Severe Fouling Biocide is a synergistic blend of multiple non-oxidizing biocides including glutaraldehyde, quaternary ammonium compounds, DBNPA, isothiazolinones, and TCMTB, combined with penetrants, dispersants, and surfactants. This multi-mechanism approach provides rapid kill of planktonic bacteria, penetration and destruction of established biofilms, dispersion of released biomass, and prevention of rapid regrowth (2-4 weeks protection). The product is effective against all major fouling organisms including Pseudomonas, Legionella, sulfate-reducing bacteria (SRB - common in refinery and oil & gas cooling systems), iron bacteria (common in iron-rich groundwater), fungi, algae, and biocide-resistant strains. It is particularly valuable for oil & gas refinery cooling towers (Jubail, Yanbu - severe hydrocarbon contamination), petrochemical plant ETPs (high COD loads), desalination plant pre-treatment (biofouling of membranes), steel and aluminum plant cooling systems (oil and grease fouling), and food processing water systems (protein and carbohydrate contamination). Our Severe Fouling Biocide is typically applied as a shock dose of 100-400 ppm for 6-24 hours, followed by a maintenance program of 20-60 ppm continuous or intermittent. The product is stable at pH 4-9 and temperatures up to 80°C. It is compatible with most corrosion inhibitors and antiscalants but should not be mixed with strong oxidizing biocides like chlorine or bromine. By using our Severe Fouling Biocide, Saudi industries can achieve reduction of existing biofilm by up to 95% within 24 hours, restoration of heat transfer efficiency (10-20% improvement), extension of time between mechanical cleaning (3-6 times longer - from 2-4 weeks to 3-4 months), reduction in under-deposit corrosion rates (by 50-70%), reduction in biocide resistant strains, and improved overall system reliability and production uptime.
Dosage in cooling water treatment programs 20 to 30 ppm for effective control of biocide activity, for cooling waters.
INNOVA BCD 417 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 25 to 50 ppm of INNOVA BCD 417 in the system. SUBSEQUENT DOSE - When the Microbial count is evident, slug feed 20 to 40 ppm of INNOVA BCD 417.
The best indication of the successful application of INNOVA BCD 417 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 417 is available in 25Kgs, 50Kgs & 200 Kgs.
