The treatment of brewery wastewater for reuse: State of the art

ScienceDirect Desalination 02/2011; DOI: 10.1016/j.desal.2011.02.035


The beer brewing process often generates large amounts of wastewater effluent and solid wastes that must be disposed off or treated in the least costly and safest way so as to meet the strict discharge regulations that are set by government entities to protect life (both human and animal) and the environment. It is widely estimated that for every one liter of beer that is brewed, close to ten liters of water is used; mostly for the brewing, rinsing, and cooling processes. Thereafter, this water must be disposed off or safely treated for reuse, which is often costly and problematic for most breweries. As a result, many brewers are today searching for: (1) ways to cut down on this water usage during the beer brewing process, and/or (2) means to cost-effectively and safely treat the brewery wastewater for reuse. Based on the available documented literature, this paper provides a review assessment of the current status of the brewery wastewater treatment processes including potential applications for reuse. Key challenges for both brewery wastewater treatment and reuse are also discussed in the paper and include recommendations for future developments.

    ABSTRACT: With an objective to assess environmental management criteria of a vinasse treatment plant (VTP) and to evaluate the critical environmental parameters, a study was undertaken in a multi-product (packaged apple juice, distillery, brewery, packaged drinking water) brewery-cum-distillery unit. The facility with a volumetric loading rate of 11-15 kg COD, 3.6-4.5 h hydraulic retention time and 20 g l-1 VSS had a scientifically managed technically sound effluent treatment system. While the water quality parameters were found within the acceptable limits, there was 99.07% reduction in BOD from 43140.0 to 398.0 mg l- and 98.61% 5 reduction in COD from 98003.0 to 1357.0 mg l-1. There was appreciable improvement in mixed liquor suspended solids (MLSS), mixed liquor volatile suspended solids (MLVSS) and sludge volume index (SVI). A striking feature was the integrated aerobic-anaerobic highly efficient Up-flow Anaerobic Sludge Blanket (UASB) treatment for biodegradation and energy production that reduced energy and space needs, producing utilisable end-products and net savings on the operational cost. The end-point waste management included terminal products such as fertile sludge, cattle feed supplement, recyclable water and biogas. Vast lagoons with combined aerobic-anaerobic approaches, biogasification unit, sludge recovery, remediated irrigable water were the notable attributes.

    • "Due to its high concentration of biodegradable organic matters, biological treatment is a good choice for the treatment of brewery wastewater (Parawira et al., 2005). Generally, aerobic treatment has been successfully applied for the treatment of brewery wastewater and recently anaerobic systems have become an attractive option (Simate et al., 2011). One of the most popular anaerobic processes for wastewater treatment is the Upflow Anaerobic Sludge Blanket (UASB). "

    ABSTRACT: Two sizes of conductive particles, i.e. 10-20 mesh granulated activated carbon (GAC) and 80-100 mesh powdered activated carbon (PAC) were added into lab-scale upflow anaerobic sludge blanket reactors, respectively, to testify their enhancement on the syntrophic metabolism of alcohols and volatile fatty acids (VFAs) in 95days operation. When OLR increased to more than 5.8gCOD/L/d, the differences between GAC/PAC supplemented reactors and the control reactor became more significant. The introduction of activated carbon could facilitate the enrichment of methanogens and accelerate the startup of methanogenesis, as indicated by enhanced methane yield and substrate degradation. High-throughput pyrosequencing analysis showed that syntrophic bacteria and Methanosarcina sp. with versatile metabolic capability increased in the tightly absorbed fraction on the PAC surface, leading to the promoted syntrophic associations. Thus PAC prevails over than GAC for methanogenic reactor with heavy load. Copyright © 2015 Elsevier Ltd. All rights reserved.

    • "Reactor has been proved to be a potential alternative as ETP in Brewery wastewater treatment; effective for COD removal and energy production (Shao et al. 2008). Simate et al, (2011) emphasised the importance of an integration of different treatment processes in order to remove impurities present in brewery wastewater efficiently; thereby forming the basis for a combination of two treatment alternatives. Anaerobic digestion requires no form of energy, as it does not require aeration. "

    ABSTRACT: The study examined the performance of an engineered system designed and constructed with anaerobic digester in treating brewery effluent. The pilot treatment system consisted of two 0.25 m3 digesters and four Constructed Wetlands (CW) with each pair of CW connected in series. The CW consists of 1200 × 1000 × 1000 mm plastic tanks, filled with 500 mm deep, 10-15 mm size granite overlaid with 150 mm thick sand (Cu = 1.15 and Cc = 6.8) substrate. The pilot CW was planted with Phragmites Karka Retz. at 200 mm centres. Effluent collected from the brewery was analysed for physico-chemical parameters using standard procedures. Performance evaluation was carried out at 2, 5, 7 and 10 days retention periods in both the digester and CW. Results showed that the brewery effluent is characterised by high organic content with a Biochemical Oxygen Demand (BOD5 ) of 1630 mg/l, which was reduced by 95.82% in the Anaerobic Digester-CW System combination, with about 60% of the BOD5 reduction occurring in the Anaerobic Digester. The nitrate, phosphate and TSS were reduced by 80.96, 82.73 and 96.31% respectively in the CW. The study showed that Anaerobic Digester-CW combination has a high potential in brewery wastewater treatment.
