Food Processing Wastewater

Biofilm (or attached growth) reactors can be effectively used to treat organic wastewater from various industries such as food processing industry. They have a number of advantages including high organic loading rates (OLRs) and improved operational stability. A flexible fibre biofim reactor (FFBR) has been developed for efficient and cost effective treatment of food processing wastewater. In the process, simple flexible fibre packing with a very high specific surface area is used as support for microorganisms. The COD removal efficiencies for a range of OLRs have been studied. The FFBR can support an increasingly high OLR, but with a corresponding decrease in the COD removal efficiency. Therefore, a two-stage FFBR was developed to increase the treatment efficiency for systems with high OLRs. Experimental results indicated that a high overall COD removal efficiency could be achieved. At an influent COD of about 2700 mg/L and an OLR of 7.7 kgCOD/m3d, COD removal efficiencies of 76% and 82% were achieved in the first and the second stage of the reactor, respectively. The overall COD removal efficiency was 96%. Therefore, even for wastewater samples with high organic strength, high quality treated effluents could be readily achieved by the use of multiple stage FFBRs.

Treatment Needs

Two food processing industries in Thailand, namely pineapple canning and tuna/sardine canning, were studied over a 10 year period to document effects of water reuse, recycling and resource recovery (both energy and product) on waste treatment needs and actual operations. Changes in terms of water consumed, energy required, waste generated, and costs per ton of raw material processed were calculated. Lower overall annual costs resulted from all water conservation and energy recovery schemes even though stricter pollution control laws were the motivating factor behind the changes. Unit design parameters of water use, energy use and waste load generated per ton of raw material processed are included for both industries to permit extrapolations for future waste treatment plant designs.
