Case Study Summary: Industrial Wastewater Treatment - Large Pulp Mill in South America (Kraft Pulp)
Challenge:
One of the largest kraft pulp mills in South America faced multiple challenges as production demands increased, pushing the wastewater treatment system beyond capacity. Key issues
included:
• Significant odors from the wastewater treatment plant (WWTP), leading to neighbor complaints
• Inefficient effluent treatment, particularly in removing phosphorus (P) and chemical oxygen demand (COD)
• Underperforming biological reactors, failing to meet strict environmental discharge standards
Solution:
SciCorp engineers collaborated with the pulp mill’s wastewater team to conduct a full-scale, three-month trial using BIOLOGIC™ SEPTIC. The trial involved:
• Setting up two dosing points in the WWTP with continuous metering pumps
• Weekly performance assessments to optimize treatment outcomes
Results:
• Significant Odor Reduction: Drastic reduction in H2S and mercaptan odors throughout the plant, especially in secondary clarifiers and belt presses.
• Improved Effluent Quality:
◦ 36% increase in phosphorus removal efficiency
◦ 23% increase in COD removal efficiency
• Increased Capacity:
◦ 25% increase in WWTP treatment capacity, processing up to 150 tons/day without needing additional aeration
◦ 10% improvement in reactor efficiency
• Reduced Waste: 10% reduction in biosolids produced
• Carbon Footprint Reduction: The trial also resulted in a reduced environmental impact.
How This Benefits Your Septic System:
BIOLOGIC™ SEPTIC offers the same benefits for residential septic systems, improving waste
breakdown, reducing sludge, and controlling odors. This leads to fewer pump-outs, better system
efficiency, and a cleaner environment around your home.
