Call for Spent Aqueous Cleaners:

EcoShield Environmental Announces Research Program for Steady-State Cleaner Process Developement

Houston, June 29, 2000:

EcoShield Environmental Systems Inc. has announced that its new aqueous cleaner regeneration test lab facility in Houston is operational. EcoShield is now accepting applications from cleaning engineers who wish to have samples of their used aqueous cleaners processed, tested and evaluated for their recyclability potential. Samples accepted for submission will also become part of an ongoing development effort to create a revolutionary steady-state aqueous cleaning system.

Traditional methods of extending aqueous cleaner bath life include adding more chemistry, filtering or separating the oils and greases, or biologically consuming the contaminants. The EcoClean ACR (Aqueous Cleaner Regeneration) System actually converts contaminants into surfactants in process, which not only reduces contaminant build up, but also replaces drag out losses, extending useful bath life far beyond traditional methods. The cleaner created by the EcoClean System is a high value emulsion cleaner of superior cleaning ability. Due to the regenerative nature of the system, the generation of wastewater is greatly reduced, along with the expense associated with wastewater treatment of traditional spent aqueous cleaners. The current Call for Spent Aqueous Cleaner Samples is a part of EcoShield’s ongoing research effort to verify cleaners and cleaning processes that are amenable to the EcoClean regeneration process.

EcoShield Environmental Systems, Inc. and The SensaDyne Instrument Division of Chem-Dyne Research Corp. ( have recently begun joint development efforts to incorporate the SynsaDyne Dynamic Surface Tension Tensiometer into the automatic process control versions of the EcoClean ACR System. [Read about the Joint Development Agreement.]  The addition of the SynsaDyne Tensiometer will permit end users to control aqueous cleaner baths in a way never before possible. According to the SynsaDyne inventor, Victor Janule, "the SensaDyne tensiometer is free of measurement error caused by temperature fluctuation, liquid level changes and various other interferences which can adversely affect other surface tension measurement methods. It will allow continuous measurement of an aqueous cleaner’s DYNAMIC surface tension and therefore permit accurate process feedback control to the EcoClean ACR System." Dynamic surface tension, as opposed to static surface tension, can tell the operator and the process controller "how fast the cleaner can clean the part" which is a time dependent variable in cleaning processes.

The EcoClean ACR System uses a novel approach to convert contaminates in aqueous cleaners into active surfactants that extend the useful life of the aqueous cleaner beyond its normal useful life span. This is more than mere filtration or removal of organic contaminants, but actual conversion of "soil into soap". In addition to being an excellent pollution prevention strategy, the EcoShield SynsaDyne System ACR combination also eliminates the usual roller coaster ride that cleaning processes typically encounter. Typically cleaning solutions require longer and longer time intervals (the time dependent variable) to clean parts as the cleaner loads up with contaminates. As the contaminate concentration increases, the surface tension of the cleaner normally increases as well.

Conversion of some of these contaminates into surfactants using EcoShield’s EcoClean ACR System then lowers (or restores and stabilizes) the dynamic surface tension of the cleaning solution. (For further information on the actual process and patents, see the white papers at This results in a more constant steady state like process for parts cleaning. This in turn leads to better quality control in areas that are easily affected by part cleanliness, such as paint and coating operations, while simultaneously increasing production and reducing costs. It can also eliminate the knee jerk reactions of defective production caused by waiting too long to dump and replace used aqueous cleaners that have exceeded their useful life. The surface tension measurements of the SynsaDyne controller can be correlated to other QA/QC data to answer the question of "how clean is clean".

Those wishing to have their spent aqueous cleaner tested for recyclability may submit a request to the inventor, Mike McGinness, at EcoShield Environmental Systems Inc. The first step to becoming a candidate for testing is to submit a brief aqueous cleaner profile data sheet. The profile form can be printed from the EcoShield web site at, or may be completed and submitted on-line. After a proposed sample has been Pre-qualified, each sample sponsor will be contacted for any additional information, notified of the next available testing schedule, and given shipping , packaging and sample collection method instructions.
