How To Manage Aqueous Cleaning Waste Disposal

Thursday, December 10th, 2015

Aqueous cleaners create safer work environments and simplify the waste disposal process. Water based cleaners are less toxic and safer than petroleum solvents but that doesn’t mean you do not need to manage the disposal process. This article will describe some ways to manage aqueous cleaning waste and a few proper ways of disposal. 

Waste Disposal Centers For Aqueous Cleaning 

The best way to dispose of leftover aqueous waste is to utilize waste disposal centers. According to Thurston County Business Pollution Prevention Program, since water based cleaners are less toxic than petroleum solvents, disposal costs are generally less. A recent study by the Washington Department of Ecology found that large waste vendors typically charge approximately 1/3 less for aqueous solutions. Furthermore, utilizing a licensed vendor reduces your liability and ensures that the waste is properly disposed. Vendors allow for more disposal management options for the different elements of aqueous disposal.  

Sludge Management For Part Washers

Every aqueous cleaning machine is different but one that utilizes filtration services. According to Environmental Protection Agency, little or no sludge will accumulate in aqueous cleaning units with filtration, but units without filtration may accumulate sludge at the bottom. This sludge may be disposed of along with waste solution. Most waste disposal companies will accept a certain percentage of solids in the waste solution. If the sludge is separated from the solution, the sludge may not be disposed of as solid waste unless tested to determine if it is nonhazardous.

Be Aware Of Illegal Disposal Methods

You cannot just dispose of aqueous waste. It is illegal to dispose of any parts washer solutions into drywells, onsite septic systems, storm drains, or onto the ground. Even though aqueous cleaning is safer and easier to dispose of, you still need to appropriately manage the waste disposal. Thurston also states, improperly disposing may contaminate your septic tank or drain field and disrupt the normal biological processes in working water cleaning systems, which may result in costly system failure. It’s important that waste is disposed in the proper way.
