background: today, in many countries, wastewater treatment plants effluent is an important part of the renewable water resources. in this case, the effluent quality standards are developed and used is important. the aim of this study was to investigate the potential use of wastewater plants effluent restricted irrigation. methods: in this descriptive - analytical study, samples was collected fr...

Wastewater Treatment Plant Design Advisor (WASDA) is an interactive computer system that could support users for designing wastewater treatment plant (WWTP) construction facilities. It is consisting of computation tools and information management capabilities, developed to aid decision makers especially engineers in solving problem on wastewater treatment process. For design purposes, WASDA can...

The uptake and effects of contaminants were measured in the insectivorous tree swallow (Tachycineta bicolor) at a wastewater treatment site. The study examined reproductive, immunological, and growth endpoints in tree swallows exposed to chlorinated hydrocarbon contaminants and to 4-nonylphenol in wastewater lagoons at the Iona Wastewater Treatment Plant, Vancouver (BC, Canada). Clutch size was...

In this paper, physicochemical characterization and analysis of total metal concentration of greases and wastewater samples from two wastewater treatment plants in the North of Morocco, Tangier and Tetouan, were carried out. The samples were taken in the winter period of the year 2011-2012. For two case studies of wastewater treatment plants in Tangier and Tetouan (WWTPTG and WWTP-TT), waste so...

Abstract. A pilot plant for treating 1,000m of textile dyeing wastewater per day with electron beam has constructed and operated continuously in Daegu, Korea since 1998. This plant is combined with biological treatment system and it shows the reduction of chemical reagent consumption, and also the reduction in retention time with the increase in removal efficiencies of CODCr and BOD5 up to 30~4...

background wastewaters with high salt content disturb the metabolic function of microorganisms causing plasmolysis or activity loss in microorganisms, so the efficiency of biological treatment of saline wastewater by conventional microorganisms will decrease. objectives this study aimed to find the outbreak of disorder in the biological wastewater treatment process and how much salt leads to lo...

Microbial fuel cells (MFCs) have been used to produce electricity from different compounds, including acetate, lactate, and glucose. We demonstrate here that it is also possible to produce electricity in a MFC from domestic wastewater, while atthe same time accomplishing biological wastewater treatment (removal of chemical oxygen demand; COD). Tests were conducted using a single chamber microbi...

In recent years, irrigating agricultural land with wastewater has become a major wastewater management practice. Irrigation has replaced much of the discharge to streams and conventional primary and secondary waste treatment for food processing wastewater (4, 11, 12, 13). Irrigating agricultural land for treatment and disposal of the food processing wastewater is a good practice if the wastewat...
