“…These could be due to various processes that took place in the brewing industry as reported in the United Nations World Water Development Report (WWAP 2017). The analysis of physicochemical characteristic showed that raw brewery wastewater has high levels of organic matter, nutrients, and solids, which corroborates the study by Jaiyeola and Bwapwa (Jaiyeola and Bwapwa 2016).…”

Background: Bioremediation is the use of biological interventions for mitigation of the noxious effects caused by pollutants in the environment including wastewater. It is very useful approach for a variety of applications in the area of environmental protection. It has become an attractive alternative to the conventional cleanup technologies that employ plants and their associated microorganisms to remove, contain, or render harmless environmental contaminants.Methods: Three parallel hydroponic treatment systems (each 2 m long × 0.75 m wide × 0.65 m deep) and one control unit were filled with brewery wastewater to an effective depth of 0.5 m. Two sets of floating polystyrene platform were used for each treatment unit to support vetiver tillers for conducting bioremediation study. The wastewater was fed to the hydroponic treatment units at hydraulic loading rate of 10 cm d −1 and hydraulic residence time of 5 days. Influent and effluent samples were collected once a month for 7 months, and analyzed to determine the various parameters relating to the water quality including plant growth and nutrient analyses.Results: Vetiver grass grew and established with well-developed root and shoots in the hydroponics under fluctuations of brewery wastewater loads and showed phytoremedial capacity to remove pollutants. Removal efficiencies for BOD 5 and COD were significant (p < 0.05), up to 73% (748-1642 mg l −1 inlet), and up to 58% (835-2602 mg l −1 inlet), respectively. Significant removal efficiencies (p < 0.05) ranged from 26 to 46% (14-21 mg l −1 inlet) for TKN, 28-46% (13-19 mg l −1 inlet) for NH 4 + -N, 35-58% (4-11 mg l −1 inlet) for NO 3 − -N, and 42-63% (4-8 mg l −1 inlet) for PO 4 −3 -P were recorded. Nutrient accumulation in the samples harvested were varied between 7.4 and 8.3 g N kg −1 dry weight and 6.4-7.5 g P kg −1 dry weight in the hydroponic treatment units during the study period. Conclusions:This study has shown suitability of vetiver grass for organics and nutrient removal in the bioremediation of brewery wastewater using hydroponics technique in addition to production of valuable biomass. Bioremediation using hydroponics is green and environmentally sustainable approach that offers promising alternative for wastewater treatment in developing countries including Ethiopia.

BackgroundThis study aims to assess suitability of hydroponic technology for treatment of brewery wastewater in a hydroponic bioreactor using Typha latifolia. Triplicated hydroponic bioreactor treatment units were designed, constructed and operated at a hydraulic retention time of 5 days with different surface loadings and mean hydraulic loading rate 0.023 m3 m−2d− 1. Young T. latifolia shoots were collected in the vicinity of study site. Wastewater characteristics, plant growth and nutrient accumulation during experiment were analyzed as per APHA standard methods and nutrient removal efficiency was evaluated based on inlet and outlet values.ResultsT. latifolia established and grew well in the hydroponics under fluctuations of wastewater loads and showed a good phytoremedial capacity to remove nutrients. Significant removal efficiencies (p < 0.05) varied between 54 and 80% for Total Kjeldahl Nitrogen, 42 and 65% for NH4+ -N, 47 and 58% for NO3− -N, and 51 and 70% for PO43−-P. The system improved the removal up to 29% compared to control and produced biomass of 0.61–0.86 kg dry weight (DW) m− 2. Nutrients retained were up to 21.17 g N kg− 1 DW and 2.87 g P kg− 1 DW.ConclusionThe significant nutrients reduction obtained and production of biomass led us to conclude that hydroponics technology using T. latifolia has suitability potential for treatment of brewery wastewater and similar agro-industrial wastewaters. Thus it could be considered as a promising eco-friendly option for wastewater treatment to mitigate water pollution. Integration of treatment and production of biomass needs further improvement.

“…This rush of global beer giants to Africa is due to the strong prospects for increasing production capacity due to economic growth, the rapid population boom, the emergence of a middle class and the urbanization. The volume of beer sold in Africa is expected to grow by 5%, ahead of Asia (3%) and Europe (1%) [6]. In Africa, the average annual intake of beverages per person is 9 liters.…”

The brewing industry generates large amounts of wastewater which are released into surface water after treatment. The aim of this study is to evaluate the performance of the anaerobic treatment of brewery wastewaters in a UASB bioreactor containing activated sludge. After sixweeks operation, 30 samples were taken. Physicochemical analyzes were carried out on activated sludge (T, pH, VFA) and raw and treated waters (T, pH, AT, CAT, TSS, and COD). These analyzes showed that the conditions of the environment were favorable to an optimal growth of the bacteria: Mbemba et al.; IJECC, 9(7): 425-434, 2019; Article no.IJECC.2019.035 426 temperatures and pH were mostly mesophilic. the ionization of VFA was continuous and their concentration increased at the exit of the bioreactor thus revealing a significant conversion of organic materials by bacteria. The average values of the physicochemical parameters of the raw and treated wastewaters respectively increased from 31.5°C to 35°C for the temperature, from 8.9 to 7.5 for the pH, to 5.54 mg/l at 0 for AT, from 12.35 mg/l to 3.45 mg/l for TAC, from 234.08 mg/l to 129.61 mg/l for TSS and from 1637 mg/l to 282, 46 mg/l for COD. The effectiveness of the treatment allowed a COD reduction ranging from 70 to 94%. Original Research Article
