“…In treated sewage, in high removal of basic pollution can be observed (COD usually >90%). Phuong et al (2018) tested the effectiveness of wastewater treatment from a cake shop using a Submerged Membrane Bioreactor with a hollow fibre membrane. The experiment confirmed that the integrated MBR system removes organic compounds from sewage successfully.…”

Wastewater from the confectionery industry is characterized by daily and seasonal variability of composition and quantity which adversely affects the process of their disposal. Confectionery plants discharge about 300-500 m 3 per month of technological wastewater. Sewage from the confectionery industry belongs to biologically degradable. It is characterized by high values of chemical oxygen demand (COD) and biological oxygen demand (BOD). The article reviews various methods used to treat wastewater from the confectionery industry. Attention was paid to the applicability of a particular method, its advantages and disadvantages and the costs of implementation. The technology of industrial wastewater treatment uses both mechanical and physicochemical methods as well as biological ones. Techniques of sewage treatment usually consist of several stages which use different processes. Low-cost materials such as natural minerals, agricultural waste, industrial waste, biosorbents, and others contribute to the improvement of aerobic sewage conditions. The main weakness of typical sewage treatment plants is their large area, high investment, and exploitation costs. Therefore, a good solution may be the use of the membrane biological reactor which combines the classical technique of activated sludge and filtration on micro-filtering membranes.

“…Europe has large scale implementation of biogas and biomethane production and is the world leader in biogas production with more than 50% of the global arned lessons from the European experience indicated the potential impacts of the system on food supply, economic, environmental, and social issues of sustainability [2]. The characteristics of raw wastewater from the cake shop showed acidic pH and average values of 1966, 1344, 30.4, and 2.5 mg/L for COD, BOD, Total nitrogen (TN), and total phosphorus (TP), respectively [3]. The BOD/COD ratio is the index of wastewater biodegradability and wastewater is considered biodegradable and could be easily treated biologically if BOD/COD is above 50% and will require seed sludge and acclimatization if it is between 30-50% since the process will be relatively low [4,5].…”

“…On the other hand, integrating suspended and attached activated sludge resulted in a significant increase in OLR to 13.3 g COD/L. d and improved TN and TP removal to reach 82% and 85% respectively [3]. Confectionery wastewater is supposed to have readily soluble fermentable fractions which make the pH of this wastewater acidic in nature.…”

“…Many municipal wastewater treatment plants suffer dramatic deterioration in the quality of the treated effluent either because of the overload of the treatment plant or the lack of power needed for aeration of the activated sludge which is the most widely used technology in Egypt for sewage treatment. The Egyptian government established a national standard for industrial effluent discharge into ___________________________________________________________________________________________________ population growth and nonsustainable water resource management, Egypt has reached a stage of water poverty, with an annual per capita share of water less than 700 m 3 . It is reported that about 16 billion cubic meters of agricultural and ter are being dumped annually into the River Nile and irrigation canals, affecting the scarcely available freshwater resources [1].…”

The goal of this study is the management of wastewater generated from a confectionery factory located at El City, Egypt. The factory produces confectionery products, chocolates, eastern and western bakery products. Laboratory analysis of raw wastewater showed high pollution load with an average COD and BOD5 of 5396 mg/L and 2526 mg/L. Most of the organic matter was present in soluble form since TSS was 908 mg/L on average. The raw wastewater showed limited nutrients concentration with average of 55 mgTKN/L and 3.3 mgTP/L. Conventional activated sludge and UASB reactors were separately investigated as treatment technologies. Aerobic sequential batch reactor (SBR) indicated hydraulic retention time (HRT) 12 hr. to produce effluent complying w 9.3kg COD/m3.d and temperature range of 20 98% for COD, BOD5 and TSS, respectively. Two and same temperature's range, showed averages of removal of 82%, 81%, 95%, and 85% of COD, BOD, TSS and oil&grease, respectively to produce effluent complying with the regulatory standards. The activated sludge quality than the two-stage UASB reactor. However, the two effective technology for the treatment.
