Pollutants from sewage wastewater are major concerns due to their environmental effects. Thus, an effective sewage wastewater treatment plant is important to ensure discharged effluent is well treated before it can be released to rivers or water streams. This study aims to evaluate the performance of the Activated Sludge Hi-Kleen Treatment Plant (ASHTP) located at H Block (ASHTP at H Block) and L Block (ASHTP at L Block) in UiTM Sarawak Branch, Samarahan Campus, Sarawak, Malaysia. The evaluation was based on physicochemical and removal efficiency namely pH, temperature, turbidity, chemical oxygen demand (COD), and total suspended solids (TSS) from raw influent and treated effluent. The findings indicated that the overall performance of both ASHTP at H Block and L Block were satisfactory where treated effluent meets the standard discharge limits of Environmental Quality (Sewage) Regulations 2009 (Standard B). For ASHTP at H Block, the removal efficiencies of turbidity, COD, and TSS were found to be 86.00, 13.76, and 88.02% respectively, in which the pH, temperature, turbidity, COD, and TSS of the treated effluent were 7.30, 28.10°C, 10.40 NTU, 14.10 mg/L and 8.90 mg/L respectively. Meanwhile, for ASHTP at L Block, the removal efficiencies of turbidity, COD, and TSS were found to be 43.20, 41.90, and 51.61% respectively, in which the pH, temperature, turbidity, COD, and TSS in the treated effluent were 7.30, 27.90°C, 21.10 NTU, 58.10 mg/L and 18.00 mg/L respectively. Proper maintenance of sewage treatment plant is important to ensure its effectiveness as well as to prolong its lifespan.

Anaerobic Sludge Blanket

The objective of this study was to evaluate the behaviour of a system comprising an upflow anaerobic sludge blanket reactor followed by activated sludge to treat domestic sewage. The Betim Central sewage treatment plant, Brazil, was designed to treat a mean influent flow of 514 L/s. The study consisted of statistical treatment of monitoring data from the treatment plant covering a period of 4 years. This work presents the concentrations and removal efficiencies of the main constituents in each stage of the treatment process, and a mass balance of chemical oxygen demand (COD) and nitrogen. The results highlight the good overall performance of the system, with high mean removal efficiencies: BOD (biochemical oxygen demand) (94%), COD (91%), ammonia (72%) and total suspended solids (92%). As expected, this system was not effective for the removal of nutrients, since it was not designed for this purpose. The removal of Escherichia coli (99.83%) was higher than expected. There was no apparent influence of operational and design parameters on the effluent quality in terms of organic matter removal, with the exceptions of the BOD load upstream of the aeration tank and the sludge age in the unit. Results suggest that this system is well suited for the treatment of domestic sewage.

O objetivo da pesquisa é avaliar o potencial de reúso dos efluentes tratados para irrigação periurbana. Foram levantados dados de uma Estação de Tratamento de Esgotos (ETE), localizada no município de Guarabira, PB, e operada pela Companhia de Água e Esgotos do Estado da Paraíba (CAGEPA), durante o período de janeiro a dezembro de 2019. Analisou-se os seguintes parâmetros físico-químicos e bacteriológicos: Potencial Hidrogeniônico (pH), Condutividade Elétrica (CE), Demanda Bioquímica de Oxigênio (DBO), Demanda Química de Oxigênio (DQO), Sólidos Totais (ST), Oxigênio Dissolvido (OD), Fósforo Total, e Coliformes Termotolerantes. Os dados foram submetidos à análise descritiva e expresso em valores mínimos, máximos e médios. Os indicadores foram satisfatórios para irrigação restrita, porém com a necessidade de tratamento complementar para determinados cultivos. O potencial de reúso   dos efluentes tratados na ETE pode beneficiar uma área de 118,7 ha considerando uma demanda de irrigação de 18.000 m³ ha-1 ano-1, o que demonstra ser um recurso sustentável e que precisa ser regulamentado no Brasil.   Palavras-chave: recursos hídricos, resíduos líquidos, tratamento de água, fertirrigação.     BERNARDINO, L.

REUSE POTENTIAL OF TREATED EFFLUENTS FOR PERIURBAN IRRIGATION IN THE MUNICIPALITY OF GUARABIRA/PB     2 ABSTRACT   Water is at the center of sustainable development and a finite resource that is in short supply, which justifies the search for management and innovation of practices that preserve it. This research aims to evaluate the potential for reuse of treated effluent for periurban irrigation. Data were collected from a Sewage Treatment Plant (STP), located in the municipality of Guarabira, PB, and operated by the Water and Sewage Company of the State of Paraíba (CAGEPA), during the period from January to December 2019, with the analysis of the following physicochemical and bacteriological parameters: Hipogenic Potential (pH), Electrical Conductivity (CE), Biochemical Oxygen Demand (DBO), Chemical Oxygen Demand (DQO), Total Solids (ST), Dissolved Oxygen (OD), Total Phosphorus, and Thermotolerant Coliforms. The data were submitted to the descriptive analysis and expressed as minimum, maximum and average values. The indicators were satisfactory for restricted irrigation, but with the need for complementary treatment for certain crops. The potential for reuse of the effluents treated in the ETE can benefit an area of 118.7 ha considering an irrigation demand of 18,000 m³ ha-1 year-1, which demonstrates to be a sustainable resource that needs to be regulated in Brazil.   Keywords: Water resources, liquid waste, water treatment, fertigation.

Influent Flow

Abstract The quality of a treated effluent changes when there is a sudden variation in the influent flow to the wastewater treatment plant during dry, rain, and storm weather conditions. In this study, various influent flow conditions in an activated sludge process are considered that affect the sensitivity of effluent variables such as chemical oxygen demand (COD), biological oxygen demand (BOD), nitrate nitrogen (SNO), ammonical nitrogen (SNH), and total nitrogen (TN) with respect to varying internal recycle flow rate (Qa), sludge recycle flow rate (Qr), sludge wastage flow rate (Qw) and oxygen transfer rate co-efficient of aerobic tanks (KLa(3,4,5)). The analysis has been carried out based on benchmark simulation model no.1 (BSM 1) plant layout which comprises of two models namely activated sludge model no.1 (ASM 1) and simple one dimensional (Simple 1-D) Takacs model. Based on the present analysis, it is observed that the changes in influent flow rate have larger impact on the effluent variables. This variation can be subdued by introducing additional tanks to smoothen the perturbations or using internal recycle rate from the fifth tank in order to maintain the flow around the optimal influent flow rate. The sludge wastage rate has a greater impact on all effluent variables except nitrogenous variables during maximum flow conditions.
