Tank Cleaning – Enzyme Treat tanks and merchant marine holding tanks can be cleaned during major vessel maintenance outages without dangerous caustic toxic chemical or personnel having to enter the tanks.
Sewage Treatment Plant – Augmentation of the biological sewage treatment system on a regular routine
will optimize biological activity and maximize system efficiency.
Drain lines and Sewage Transfer Lines – Sewage and galley drain lines can be kept clean of organic blockages via routine maintenance additions.
Sewage Holding /Tank Cleaning
Tank should be filled and pumped empty twice using fresh or saltwater to purge and loose soils or water.
Dump flush water to waste.
Refill tank to 50% capacity using fresh or salt water.
If tank have an aeration system, air flow should be adjusted to provide steady rolling agitation of tank. If no aeration system exists, a temporary system may be rigged utilizing an air spurge line situated near the bottom of the tank.
4. Prepare a solution of Enzyme Treat utilizing 1.0 pound of Enzyme Treat/1 gallon of water (0.5 kg/4.0 liters).
Optimum water temperature for make-down is 95° F to 100°F (35°C). Do not exceed 105° F(40°C).
Although bacteria can function in temperatures down to 40° F (5°C), activity is optimum at 80°F (27°C) to 100°F (38°C). Prepared solution should be allowed to stand with occasional stirring for 60 to 90 minutes prior to addition to tank. Total dosage rate to tank should be a minimum of 3 pounds of Enzyme Treat per 1,000 gallons (7 kg/4,000 liters) of tank capacity.
Dosages may be adjusted for highly fouled tank
Add the solution of Enzyme Treat to the tank, fill the tank to approximately 95% of capacity and maintain
continuous aeration and mixing for 48 hours. Be certain that the tank is adequately vented to allow air from aeration to escape.
6. At conclusion of cleaning system, discharge tank volume and rinse twice by filing to capacity with fresh water or salt water dumping to waste.
7. If disinfection is required, dry chlorine may be dissolved in water and added at a dosage of 2 pounds/1,000 gallons of tank capacity while the tank is filled and aerated.
At conclusion of disinfection, tank may be dumped, flushed and placed back in operation.
