How we Operate

Conversion Process

Our customer’s needs come first. We quickly work from initial contact to plant trials and/or conversion while ensuring an easy transition. Our four-step process is simple, yet effective.

approach  to  our  customers

We analyze neutralization system information such as retention time, metal concentrations, and discharge limits in order to identify which alkali are best for your system.

Laboratory testing is conducted, incorporating information on current product usage, sludge disposal cost, and projected alkali reduction. From here, we can recommend the most cost-effective alternative.

Plant trials can be arranged on any scale, from drums to full truckloads, without taking the current neutralizer off-line. Our work ensures the trial product is used most effectively, without interfering with existing production.

We develop a plan for a full-scale conversion. After the conversion, we continue to provide prompt deliveries, quality service, and ongoing technical assistance.
