M.W. Watermark Dewaterability Laboratory

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 small portable pilot filter press units for on-site testing. We can determine the most effective feed pressures, fill times, filter media and sludge conditioning.
