A paper mill wastewater facility was treating 940 tons of paper bags, recycled linerboard, and corrugating medium, daily. The mill was interested in improving wastewater operating efficiency and lowering operating expenses over their standard polymer usage. The plant was experiencing filamentous bacteria, solids, and bulking issues in the final clarifier. It was discharging 4,000 pounds of fiber per day into the Ohio river.
The combined effluent from two anaerobic ponds filled an aerobic pond before clarification. After clarification, effluent was discharged to the river and the biosolids were processed by a belt press for thickening before landfill application.
A 9-month test was developed in which Huma Environmental® BIO ENERGIZER® was administered to make nutrients more available to wastewater microorganisms, thereby stimulating natural bio-oxidation processes and enhancing sludge reduction. BIO ENERGIZER® applied over a period of 9 months resulted in reduced filamentous bacteria, bulking issues, and total suspended solids (TSS.) Turbidity in the effluent dramatically improved with $50,000 in polymer savings in the final clarifier. Additionally, fiber discharge was reduced, as were the BOD and COD levels in the effluent.
Huma Environmental® BIO ENERGIZER® is a formulation of nutrients, organic acids, natural biological stimulants, and energy systems that balance the natural microbial ecosystem to increase bio- oxidation capacity in lagoon systems. Wastewater facility operators have been using BIO ENERGIZER® for many years to cut their sludge-hauling costs.

December 8th is #NationalChristmasTreeDay. This of course sets up the great debate, real or fake? While every family weighs the pros and cons of choosing the Tannenbaum they rock around, a popular nation is that fake trees are more eco-friendly. After all, they can keep for many years, right? And isn’t it bad to cut down real trees merely for decoration? Not so fast.
