Using state of the art science Hydrologica transform poor performing wastewater and anaerobic digestor plants into highly efficient processes. The heart of any anaerobic digestor or wastewater treatment system is the biology. It may be affected by anything that it comes into contact with, including chemicals designed to help. Within minutes of testing, their technology determines the exact biological health of any aerobic or anaerobic plant. They locate and reduce sources of toxicity and dramatically increase the healthy concentrations.
