| FOR USE IN HYDROCARBON PRESERVATION TO CONTROL THE GROWTH OF PROBLEM MICROORGANISMS ASSOCIATED WITH FUEL. DIRECTIONS FOR USE Use slug dosage or intermittent metering of Bio Kleen® Diesel Fuel Biocide to attain "shock-treatment" concentrations of contaminated diesel fuel tanks or for maintenance-treatment concentrations. SHOCK TREATMENT OF DIESEL FUEL BULK-STORAGE OR EQUIPMENT TANKS: Treat total capacity of each tank - not the amount of fuel in the tank at time of treatment. Add one ounce of Bio Kleen® to each 20 gallons of equipment fuel tank capacity (see treatment ratio chart on this page). After treatment has been added, fill the tank with diesel fuel to maximum capacity so that the rising level of diesel fuel treats the entire interior walls of the tank. MAINTENANCE TREATMENT OF DIESEL FUEL BULK-STORAGE OR EQUIPMENT TANKS: Treat total capacity of each tank at the ratio of one ounce of Bio Kleen® to each 55 gallons of diesel fuel in the tank (see treatment ratio chart on this page). After treatment, fill tank to maximum capacity. SHOCK TREATMENT AND MAINTENANCE TREATMENT: Recirculate fuel in tank for 30 minutes following treatment, if possible. Let diesel fuel set for eight hours before using to achieve maximum effectiveness. Treatment may result in additional accumulations of water and dead microbes at bottom of tank. If so, pump or drain tank bottoms to complete tank cleanup. WHEN TO USE A BIOCIDE: Make visual inspections of bulk-storage tanks. Dark, slimy growth may be detected at the interface area between the diesel fuel and the water-bottom or throughout the fuel. A "rotten egg" odor also may be detected. Look for slime on interior walls of tanks and in the sump area - check water drawn from the sump area for slimy debris. Microbial growth can multiply rapidly and may form into long strings and form mats or globules. These are the most common signs of contamination and require immediate treatment. DEVELOP A TREATMENT SCHEDULE: Shock treatment may be performed to solve contamination problems, followed by maintenance treatments at regularly scheduled intervals. Or, the shock treatment may be repeated every three months. Following treatment of tank, inspect filters frequently until plugging no longer occurs. PRACTICE GOOD HOUSEKEEPING: Although Bio Kleen® dual-phase biocide is effective in both diesel fuel and water, it is recommended that accumulated water be drained or pumped regularly from tank bottoms and that sump areas be drained. Filtering also is recommended to remove fungal debris. Inspect filters and screens regularly. A good maintenance program can reduce microbial growth and increase effectiveness of shock and maintenance treatments.
