Housekeeping
Many wash racks and environmental service companies shy away from using solvents due to cost. Pretreating viscous or layered soils with solvents can accelerate cleaning time and lower waste water costs.
For example, in first the picture below, this tank was covered in layers of a thick heavy hydrocarbon resin. After multiple attempts, with a series of different detergents and degreaser yielded less than desirable results. Dyna-Strip 777 Solvent Stripper was then introduced to the contaminant and quickly began stripping the sticky resin off the outside of the tank. The middle picture above is a side by side comparison of the results. With a quick, cold water rinse, the third picture depicts one side of tank after cleaned with just one round of application. No heat was needed for this application but can be heated to strengthen cleaning capabilities.
The net chemical cost in this application was much less labor intensive and was cleaned in half the time.
Solvent washing set up tanks and hard to clean products
Presolve
Presolving is simply spraying the interior of the dirty tank with a solvent to break down the product or waste in the trailer. Many tank wash facilities find that they have saved time and money by using this cleaning method. The pictures below show two different types of Presolve pumps
Using non-EPA listed, higher flash solvents to presoak and breakdown difficult products keeps your cleaning vat solutions from being contaminated quickly. The presolve process will thin out the heavy residues in the tank which will allow you to drain them off prior to the hot vat wash. We offer a variety of solvent strippers designed specifically for presolving. Solvent strippers can be diluted with diesel, kerosene, or mineral spirits to lower the cost per gallon. Contact us today for solvent dilution recommendation for all solvents we offer.
Circulating small amounts of solvent works just like soaking the tank in solvent
When product has “set up” in a tank, often times just spraying a light coat of solvent on the set product will not dissolve it completely because the solvent did not have enough contact time. Circulating a small amount of solvent without filling the entire vessel. Our Eliminator Kit is a package unit that allows you to circulate small amounts of solvent into vessel sizes ranging from 200-20,000 gallons.
