M.W. Watermark maintains an in-house laboratory for determining the most effective equipment, equipment sizing, filtration media, and dewatering techniques for your specific application.

This valuable service is offered as a tool to determine the optimum treatment, chemicals, dosages, conditions, etc. After treatment, we can return to you the clean water (filtrate) and filter cake, along with an analytical report of our findings.

Our services range from feasibility testing of your materials to providing portable pilot filter press units for on-site testing. We can determine the most effective feed pressures, fill times, filter media and sludge conditioning.

In the following video, we tested a potential solution for a customer who sent us a slurry sample from a small waste stream that they wanted to dewater. Following testing trials we were able to make dewatering recommendations as well as supply the analytical data supporting our recommendations.
