DO-ALL #18 is a surface-active agent, which can be used to reduce the flammability of surface crude and floating fuel prior to possible ignition, or after the fire is extinguished.
Open Water / Coastal Clean-up
Specific field conditions such as composition of water, composition of oil/fuel, viscosity of oil/fuel, temperatures of air & water, length of time oil/fuel has been exposed to atmosphere, wind and wave conditions, amount of agitation, possible and methods of application available, must be considered by the responsible party on the scene of the clean-up.
DO-ALL #18 may be applied to the oil spills using either salt or fresh water as the dilutant. Dilutions of one part DO-ALL #18 to thirty parts water (1 to 30) are recommended as a first choice. However, the dilutions are subject to the responsible parties' evaluation. In cases where a light spill is evident, 1 to 50 will usually suffice. In heavy seas, dilutions as low as 1 to 20 or 1 to 15 may be necessary.
The application of DO-ALL #18 maybe made directly from the drum by fitting a "T" connection and pumping salt or fresh water across the junction, pulling the dispersant DO-ALL #18 from the drum into the water stream and onto the oil spill. Portable centrifugal water pumps are a satisfactory means of moving the dispersant from the container to the spill. If the spill is confined to a small area, a hand pump connected directly to the drum will often suffice. Hose diameters and hose lengths will relate to the capacities required for the specific situation, as well as the distance from the pump to the container and to the spill. A fire hose has been used successfully. With a hand pump a small diameter hose is adequate. Fog nozzles have been used to provide a fine spray of DO-ALL #18. Any type of hose nozzle can be used; however, a spray rather than a coarse stream is desirable.
Once DO-ALL #18 has been applied to the oil surface it is necessary to agitate and thoroughly mix the oil/dispersant into the water. In open unconfined area use of ships' propeller, has been determined to be a practical method of agitation. Mixing with high shear tends to break the colloidal suspension oil DO-ALL #18 into smaller panicles providing for a better dispersion. By passing over-the grill on a skid system, the vessels propellers will churn the water and promotes mixing of the oil/DO-ALL #18/water mix and subsequently dispersion of the spill. Two or more vessels may be used simultaneously to apply the dispersant and to agitate the water for better efficiency.
For coastal clean up, a boat with an outboard motor or small inboard motor is sufficient.
In general each gallon of DO-ALL #18 mixture 1 to 30 with water will disperse 50 to 100 square feet of a thin oil film.
Where larger spills are encountered particularly in very cold water, with a minimum of sea stats, it's best that mechanical methods are used first and DO-ALL #18 used for mopping up, after such mechanical methods have been completed. Mechanical methods for removal include the use of pumps, booms, skimmers, absorbents and vacuum devices.
If solvent based dispersants are used at the direction of the on scene coordinator to remove the concentrations of heavy crude oils and floations that have been on the open sea for a period of time, and have become progressively more viscous-especially if the oils have become tarryaspheltic residues. DO-ALL #18 can be used to disperse the solvents used and promote quicker biodegradation, since DO-ALL #18 is NON-TOXIC, it can be satisfactorily used to clean animals and water fowl without danger to the health of the animals and birds. Some other applications for DO-ALL #18 include removal of oil residue from docks and pilings, ship docks, and shipsides, including ships made of metal, wood, concrete and plastic.
How to Treat Oil Spills at Sea Using DO-ALL #18
Herding - confining oil to a given area prior to its removal by different means. Herding occurs when the spill is contained for the purpose of reclaiming the oil, either to be run through an oil-water separator or gathering it for disposal.
DO-ALL #18 is not to be used for this purpose as our product will, when properly used with agitation, break down the oil into infinite particles, and as long as movement is occurring, will continue to biodegrade the oil. DO-ALL #18 is used when there is a need to get rid of as much oil as possible before it is driven by the winds an rough seas towards the shore.
Dispersing - rapidly accelerating the break-up of oil, in such a way to enable the natural biodegrading process of the environment to take over.
DO-ALL #18 is to be used for this purpose. Because of its formulation, it will emulsify the oil and as stated before, with proper methology continue to break down the oil. The degraded oil will not sink to the bottom, nor will you see the oil floating on top. When action is working DO-ALL #18, water, agitation, then the broken down residual will float harmlessly in the water channel until biodegraded 100%, and nothing left. When DO-ALL #18 is used on a spill, the large oil mass will be breaking down into smaller groups of oil molecules of hydrocarbons. Once this occurs the oil itself becomes biodegradable, allowing for digestion by plankton, protozoan and other fish, or evaporates into the atmosphere by nature's own catalytic breakdown and disposal by the wind and waves. The outstanding feature of DO-ALL #18 is that this product will not sink the oil to the bottom, which would cause considerable damage to plants and marine life.
DO-ALL #18 in Action
We took a regular water bottle, added to it plain water and some used motor oil. To this we added DO-ALL #18 equal to the amount of oil. The bottle was shaken to provide the agitation necessary for the DO-ALL #18 to work and the oil was completely emulsified. When emptied, the bottle rinsed clear with water.
