Client Reviews on Industrial Wastewater Treatment

The membrane bioreactor installation at our pulp mill in Prince George was completed on schedule. After the first month of operation, we observed BOD consistently below 10 mg/L and TSS below 5 mg/L, meeting Fisheries Act section 36 criteria. The chemical cleaning protocol required adjustment during the second week due to flux decline, but the team responded within 24 hours. The sludge production reduction of 30% compared to our previous activated sludge system is already reflected in our monthly operating costs.

Communication during the hydrocyclone optimization project for our gold mine in northern Ontario was clear and structured. The field trials were conducted over three weeks, with daily updates on pressure adjustments and separation efficiency. The final configuration achieved a d50 cut size of 45 µm at 120 kPa, reducing downstream maintenance frequency by 40%. The only constraint was the availability of spare vortex finders, which delayed one trial by two days. The team documented all pressure drop correlations and wear rate projections for the rubber-lined cyclones.

This is our second engagement with the team, following the pH control system installation at our chemical plant in Ontario. The returning client experience was consistent with the first project: the dual pH sensor system with PID-controlled lime slurry injection maintained effluent pH between 6.0 and 8.5 for 99.7% of recorded intervals over six months. The fail-safe bypass logic was tested during a power fluctuation in month four and operated as designed. The sensor calibration protocols provided in the documentation have been integrated into our standard operating procedures.
