UPGRADE OF WASTE MANAGEMENT PROGRAM

Phoenix was engaged to improve the liquid waste management program at a specialty organic chemicals manufacturer. The plant generated significant quantities of hazardous liquids for off-site disposal. A wastewater inventory and sewer survey was used to identify significant wastestreams generated in each production campaign and determine the best management system. Wastewater segregation, off-site disposal, pretreatment, and direct discharge were evaluated. Treatability studies were performed on mixtures of product wastes combined to simulate various production campaigns. PHOENIX prepared process designs and cost estimates for pretreatment and direct discharge.

DESIGN OF MEMBRANE BIOREACTOR (MBR)

FOR COMMERCIAL LANDFILL LEACHATE

A treatment investigation and detailed design was performed to pre-treat 100,000 gpd of commercial landfill leachate for ammonia. Treatment investigations were performed using SBR technology, but due to dispersed growth and high effluent solids, a nitrifying MBR was selected for design. The system is designed to remove over 3000 lbs per day of ammonia. The detailed design was performed on a fast-track basis to enable construction to begin prior to design completion. The facility has successfully operated for years.

RETROFIT OF BIOLOGICAL PRETREATMENT FACILITY

An overloaded anaerobic/aerobic treatment plant at a food plant was converted to an activated sludge system. The treatment process was converted over a one-month period without the addition of additional treatment basins. From the time of start-up, the effluent was within compliance with the pretreatment permit.

WASTEWATER TREATMENT PROCESS DESIGN

FOR ORGANIC CHEMICALS PLANT

A pilot scale treatment investigation was designed and conducted to evaluate the effect of changes in the effluent on meeting BAT requirements. The unit was operated for four months. The resulting data was used to develop the process design for a $4.5 million upgrade to the wastewater treatment system for this organic chemicals plant. The 350,000 gpd plant included equalization, activated sludge, ammonia stripping and filtration. An energy conserving design was developed and waste process heat was used to permit a high degree of biological treatment year-around. The plant consistently met or exceeded permit requirements. Phoenix personnel also provided startup assistance, and operating, and permitting assistance to this facility.
