Process that Works This new “Stage 1 UF system” removes solids and concentrates the waste 25 times, equivalent to a 96 per- cent reduction in water content. Cleary is investigating options for recycling the oily concentrate.
Removal of the solids enables the bioreactor process to work smoothly. Off-site disposal of bioreactor waste has been reduced tenfold, from an average of 10 truckloads per month (at a cost of $242,000/year), to only one and a half truckload per month (at a cost of $32,000/year) [Figure 3]

Prior to the installation of the Stage 1 UF system, the MBR permeate contained a wide variation in COD levels, ranging from 1,500 to 12,000 mg/1. With the Stage 1 UF system, the MBR system now produces permeate with COD of only 30 to 300 mg/l. The MBR permeate now is well below the discharge standards set for the municipal wastewater system (COD <500 mg/l) even without pol- ishing with RO. As a result, the RO system was shut down and permeate from the MBR is discharged directly to the sewer.

COD

Cleary calculates that the total annual cost of off-site disposal of waste has been reduced from $332,000 to $104,000, a 69 percent reduction amounting to a savings of $228,000 per year.

“Uncontrolled wasting from the biological tank caused a mess and it became extremely expensive to haul away all of the waste,” said Cleary. “We knew that we needed to find an effective way to prefilter the feed water to the MBR in order to remove the oil and other components that were wreaking havoc on the MBR system.”
FEG™ Tubular Membranes Cleary and his team worked with almost two dozen vendors to test a wide variety of pretreatment solutions, utilizing many different types of membranes. For example, a grant from the U.S. Department of Energy fund- ed the testing of a spinning membrane system. The system worked effectively, but it was not commercially available and high electricity costs made the system uneconomical.
In 2006, the Twinsburg plant installed a KONSOLIDATOR™ 150 Industrial Wastewater System from Koch Membrane Systems Inc. (KMS) of Wilmington, Mass. The pre-engineered, pre-packaged system contains 150 FEG™ PLUS tubular UF membranes.
