Effective control begins with the formulation of the coolant concentrate and continues with management of coolant concentration, pH and microbial population in the sump. New technology now makes it possible to accurately measure all three parameters in the field in 15 minutes. Armed with these data, scientifically sound recommendations can be made immediately, on site. Practical, field applications of this strategy will be presented and discussed. The growth and proliferation of bacteria turn the fluid rancid, which results in loss of lubricity and premature disposal.
Spoiled fluid is classified as a hazardous waste and disposal costs are significant.
Stasys, Inc. specializes in the assessment and management of coolant chemistry and biology. Tramp oils and many metalworking fluids are excellent food for microorganisms. Microbial growth degrades this fluid, reducing its lubricity and coolant properties, and ultimately compromising the performance of the fluid. These result is lower product quality, shortened tool life and poor working conditions. We have designed a simple management program for water-based metal working fluids around the management of microbial populations to prevent coolant degradation.
