Biodegradability enhancement and detoxification of cork boiling wastewater (CBW) are required for the successful implementation of biological treatment options. We studied the possibility of achieving these goals through ozonation pre-treatment by experimenting on the effect of ozone dose and pH. The CBW used had a pH of 5.81, a chemical oxygen demand (COD) of 1,865 mg L(-1), a biochemical oxyg...

In the present study the aim of investigation is physical and chemical parameters of ground water and soil. By selected Physical and chemical parameters it is found that (1).Biological oxygen demand (BOD) and chemical oxygen demand (COD) are directly proportional to each other where dissolved oxygen (DO) is indirectly proportional to BOD and COD. (2). Total dissolved solids, alkalinity and hard...

a bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. removal of chemical oxygen demand (cod) and biochemical oxygen demand (bod5) was investigated. the experimental setup consisted of influent and effluent tanks, and membrane modules using polyvinyl di–fluoride (pvdf) hollow fibers. the operation program included suction and backwash steps whic...

Nowadays, the increase of human population every year results in increasing of water usage and demand. Saen Saep canal is important canal in Bangkok. The main objective of this study is using Artificial Neural Network (ANN) model to estimate the Chemical Oxygen Demand (COD) on data from 11 sampling sites. The data is obtained from the Department of Drainage and Sewerage, Bangkok Metropolitan Ad...

The oxidation behavior of twenty organic chemicals from four different classes (sugars, benzene derivatives, alcohols and carboxyl acids) were investigated using the official chemical oxygen demand (COD) methods (i.e., permanganate and dichromate methods) and their oxidation levels compared with the theoretical oxygen demand (ThOD) values. In addition, the correlation between the official COD a...

Abstract Microbial desalination cells (MDCs) exhibited an economical value with large promises as a useful treatment solution. MDCs threefold applications to efficiently treat wastewater and produce electricity simultaneously accomplish were investigated in this work. The study examined the influence of various performance parameters including co-substrate, temperature, pH, salt concentrations ...

<p>This study aimed to explore the effect of pure oxygen aeration on generation soluble microbial products (SMP) when activated sludge was under toxic stress condition phenol. Two parallel sequencing batch reactors, one with air and other aeration, were used investigate relationships among effluent chemical demand (COD), N-acyl-homoserine lactones (AHLs), community, extracellular polymeri...

background low-cost anaerobic sequencing batch reactor (asbr), which is widely used for controlling high-organic wastewater, is an effective method to remove chemical oxygen demand (cod). objectives the main objectives was evaluating the feasibility of using asbr in the treatment of synthetic dairy wastewater, determining its removal efficiency, and assessing the effect of temperature on operat...
