Enhancing the Biological Oxidation of H2S in a Sewer Pipe with Highly Conductive Concrete and Electricity-Producing Bacteria
Hydrogen sulfide (H 2 S) generated in sewer systems is problematic to public health and the environment, owing to its corrosive consequences, odor concerns, and poison control issues. In a previous work, conductive concrete, based on amorphous carbon with a mechanism that operates as a microbial fuel cell was investigated. The objective of the present study is to develop additional materials for highly conductive concrete, to mitigate the concent…
Influence of Particle Size and Zeta Potential in Treating Highly Coloured Old Landfill Leachate by Tin Tetrachloride and Rubber Seed
Old leachate normally has a low organic compound content, poor biodegradability and is hard to biologically treat. The efficacy of tetravalent metal salts as a coagulant and the application of a natural coagulant as a flocculant in landfill leachate treatment is still inconclusive. Hence, this study aimed to evaluate the potential application of tin tetrachloride (SnCl 4 ) as the main coagulant and the rubber seed ( Hevea brasiliensis ) (RS) as t…
Effects of Stepwise Temperature Shifts in Anaerobic Digestion for Treating Municipal Wastewater Sludge
In wastewater treatment plants (WWTP), anaerobic digester (AD) units are commonly operated under mesophilic and thermophilic conditions. In some cases, during the dry season, maintaining a stable temperature in the digester requires additional power to operate a conditioning system. Without proper conditioning systems, methanogens are vulnerable to temperature shifts. This study investigated the effects of temperature shifts on CH 4 gas productio…
Heavy Metals in Harvested Rainwater Used for Domestic Purposes in Rural Areas
Rainwater harvesting is considered one of the most important water resources in the Palestinian countryside. In this research, the study area chosen for the study was Yatta town in Hebron city. 75 water samples were collected from 74 cisterns in a number of neighborhoods in Yatta, and a structured household survey was conducted with the same households where the water samples were collected. Statistical analysis was made using the SPSS software. …
Poultry Slaughterhouse Wastewater Treatment Using Submerged Fibers in an Attached Growth Sequential Batch Reactor
In this study, a sequential batch reactor (SBR) with different types of fibers was employed for the treatment of poultry slaughterhouse wastewater. Three types of fibers, namely, juite fiber (JF), bio-fringe fiber (BF), and siliconised conjugated polyester fiber (SCPF), were used. Four SBR experiments were conducted, using the fibers in different reactors, while the fourth reactor used a combination of these fibers. The treatment efficiency of th…
Artificial neutral networks for predicting municipal activated sludge wastewater treatment plant performance
Artificial neutral networks (ANN) are used in analyzing the factors affecting the removal of organic pollutants and suspended solids in the municipal wastewater treatment plant, Painesville, Ohio, using the activated sludge process. The average raw, settled, secondary, and final BOD concentration were 117, 68, 6, and 2 mg/L, respectively. The corresponding TSS values were 114, 54, 12 and 2.2 mg/L, respectively. The overall BOD and TSS removal eff…
Effect of bioaugmentation on activated sludge treatment of potato wastewater
The purpose of this study was to determine the effect of an aerobic bioaugmentation process on the activated sludge treatment of potato wastewater. Parameters investigated included types of live liquid microorganisms (LLMO), aeration time, LLMO dosage and wastewater strength. Types of LLMO included S‐l, G‐l, E‐l, N‐l and NEW‐1. TOC (total organic carbon) and MLVSS (mixed liquor volatile suspended solids) were determined during the bench scale aer…
Comparative study of adsorption capacity of various adsorbents for treating dye wastewaters
The objective of this laboratory study was to determine the effect of dosage, contact time and type of adsorbents on the color and COD (chemical oxygen demand) removal for dye wastewaters. The adsorption parameters for Langmuir and Freundlich isotherms and mass transfer coefficients from bulk solution to particle surfaces for disperse dye were also determined. The adsorbents used in this study included powdered activated carbon (PAC), granular ac…
Full‐scale study of activated sludge treatment of low strength municipal wastewater
The objective of this full‐scale study is to determine the treatment performance of the activated sludge process for treating low strength municipal wastewater. The plant is located in Painesville, Ohio, and discharges its treated effluent into Grand River. The average plant wastewater flow was 3.43 MGD (million gallons per day). The plant performance was evaluated for a 12‐month period in 1989. The low strength municipal wastewater contained 104…
Statistical analysis of factors affecting activated sludge reactor performance
A statistical analysis was conducted on factors affecting the removal of organic pollutants from municipal wastewaters in activated sludge reactors. The factors include bioaugmentation, sludge age, hydraulic detention time and waste strength. Wastewaters were obtained from the Easterly and Southerly Wastewater Treatment Plants in Cleveland, Ohio. A 20‐day sludge age, a 24‐hour detention time, and high waste strength resulted in the best organic r…
Optimizing coagulation of municipal wastewaters for turbidity removal
The objectives of this laboratory study were to determine the effect of types and dosages of coagulants on the removal of turbidity from municipal wastewaters. Wastewaters were collected from Southerly Wastewater Treatment Plant, Cleveland, Ohio and Central Wastewater Treatment Plant, Solon, Ohio. Wastewaters from the Southerly plant consisted only of samples taken after primary settling. Wastewaters from the Solon plant consisted of samples take…
Bio‐conversion of accumulated sludge with bacterial augmentation process in aerated lagoons for municipal wastewater treatment
The objective of this study is to determine the feasibility of using a bacterial augmentation process with a bacterial culture product (LLMO) addition in the bio-oxidation of accumulated sludges in the aerated lagoons in municipal wastewater treatment plant. Mauldin Road Wastewater Treatment Plant, Greenville, South Carolina, of Western Carolina Regional Sewer Authority was selected in this field investigation. LLMO was added to the influent to t…
Effect of temperature on oxygen transfer rate in wastewater treatment
In this paper, discussion and comparison of percent error between empirical temperature coefficients and theoretical temperature coefficients were made. The applicable temperature ranges for empirical temperature coefficients were also discussed in this paper. After considering the opposite combined effects of oxygen deficit and viscosity of liquid on oxygen transfer rate, it was found that viscosity of liquid is the main factor affecting oxygen …
Batch adsorption of organic pollutants from oxidation pond effluents using fly ashes
The batch shaking adsorption study was conducted to determine the potential of fly and volcanic ashes in removing organic pollutants from oxidation pond effluents. Factors affecting organic pollutant removals, such as concentrations and sizes of fly and volcanic ashes, initial pond effluent organic concentrations, washed and unwashed conditions of fly and volcanic ashes, were investigated. The TOC (total organic carbon) removal efficiency varied …
