Jar testing
Biological study
Our biological assessments combine DNA analysis and microscopic examination to evaluate microbial health and identify sludge bulking issues. The resulting report provides targeted recommendations on improving biomass health, enhancing biological stability, and optimising treatment plant performance.
Antifoam tests
Using a closed-loop system, we conduct antifoam testing to determine the most effective foam control solutions for your wastewater treatment process. This ensures optimal product selection to prevent foaming-related inefficiencies while maintaining process stability.
Formulations advice
Our experts provide optimised formulation recommendations using a selection of antiscalant polymers and phosphonates, tailored to your specific water composition and equipment setup. Together with our partners, we offer simulation-based project support at our supplier’s laboratory, helping to refine treatment strategies for maximum system efficiency and longevity.
