VI. RECOMMENDED APPLICATION PROCEDURE
1. Application Method:
United's ZYME-FLOW is a chemically designed product that will make heavy crudes more pumpable, and break the adhesion between oils and soil, rock or sand.
ZYME-FLOW can be applied where the contaminated soil or sand is temporarily removed and placed into a device that can provide mechanical agitation (e.g., a cement mixer or a fractionating tank). Unagitated tanks may also be used, but more time will be required to achieve the goal.
Add ZYME-FLOW solution to the tank. As agitation continues, oils with a specific gravity of less than one will float, while oils with a specific gravity of greater than one will settle. The floating or settled oil can then be removed from the soil or sand. As ZYME-FLOW will not emulsify oils, the recovered oils are almost anhydrous, and the water can be collected and reused. Another method is to physically isolate a small area that is to be cleaned with damming collars, sand bags or other means on the sides and a none permeable layer on the bottom (if possible). Then wash the contaminated area with ZYME-FLOW solution using a pressurized water stream. Keep the area super-saturated with water for several hours to allow oil residues to float to the surface for collection.
ZYME-FLOW can be used to wash the inside or outside of a ship or barge that has been contaminated with oil, using a high pressure sprayer. Bilges of a ship, or barge can also be cleaned using a 1% ZYME-FLOW solution, and allowing the natural movement of the ship to provide the agitation.
2. Concentration/Application Rate:
The exact dilution of ZYME-FLOW will vary between 50:1 and 200:1 depending on temperature, viscosity and type of petroleum product.
3. Conditions for Use:
ZYME-FLOW is effective in all non-frozen waters with greater efficacy as the temperature increases. The product efficiency is not affected by salinity, but it will be affected by tar sand.
