Bioremediation
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.

A citrus plant struggled with poor settling in the clarifier of its wastewater treatment, which caused the sludge blanket to remain high. Even at a low flow rate of 1.2 million gallons per day (MGD), the high sludge blanked allowed less than 18” of free board. The slightest flow increase caused solids to carry over the weir with the effluent. Since the citrus plant frequently produced wastewater flows 1.5 to 2.5 MGD, the wastewater treatment plant continued to suffer from solids washout and clarifier effluent total suspended solids (TSS) excursions. The citrus plant wastewater treatment was a 6 million gallon per day (MGD) traditional aeration system with secondary clarification.
