Removal of pharmaceuticals with ozone at 10 Swedish wastewater treatment plants
Pilot-scale tests were run with ozonation for reduction of 24 pharmaceuticals at 10 full-scale wastewater treatment plants in southern Sweden. Reduction was evaluated based on doses of 3, 5 and 7 g O3/m3 at all plants. The reduction of pharmaceuticals reached on average 65% at 3 g O3/m3, 78% at 5 g O3/m3 and 88% for 7 g O3/m3 in terms of total concentration of pharmaceuticals. Specific ozone ...

Determination of conventional velocity gradient (G) using CFD technique for a pilot-scale flocculation system
Achieving uniform mixing conditions are essential for the flocculation process to optimize floc size and avoid floc-breakup. Limited literature is available on establishing consistent operational conditions and procedures for pilot-scale flocculation systems, which have tank sizes smaller than full-scale and larger than jar-test equipment. In this study, the influence of mixing speeds on the ...

An approach to wastewater treatment in organised industrial districts: a pilot-scale example from Turkey
In this study, a detailed wastewater profile and treatability studies of Demirtas Organized Industrial District (OID) were undertaken on a pilot-scale. The industrial categorisation of Demirtas OID was determined, and the wastewater characterisations of each industrial sector were analysed and the flow-rates were measured. The results were used to design a wastewater treatment plant for Demirtas ...

Technical Vocational Institute - Albuquerque, New Mexico - Arsenic Treatment System
Technical Vocational Institute Community College (TVI) is located in Albuquerque, New Mexico and services approximately 400 students. In 2005, AdEdge Technologies Inc. (AdEdge) was selected to assist in the design of a full-scale arsenic treatment project for the small community system. Detected arsenic concentrations were approximately 26 parts per billion (ppb). The pH of the water is ...

Wire manufacturing facility - Case Study
Bench-Scale Stormwater Treatment Study A large wire manufacturer in Washington State asked Dungeness Environmental to perform a treatability study on their stormwater run-off. The run-off requires remediation prior to discharge for turbidity, zinc, copper and lead concentrations. Dungeness performed an initial screening test in the lab simulating a variety of water treatment techniques for an ...

Occurrence of earthy and musty odor compounds (geosmin, 2-methylisoborneol and 2,4,6-trichloroanisole) in biologically treated wastewater
The concentrations of earthy and musty odor compounds (2-methylisoborneol (2-MIB), geosmin and 2,4,6-trichloroanisole (TCA)) in treated wastewater were measured. Concentrations of 2,4,6-TCA (4.3–37.7 ng/L) and geosmin (3.7–42.2 ng/L) higher than their odor thresholds were detected for effluents from large-scale treatment plants. The effluent from a small-scale wastewater plant ...

Dewatering optimization with in-line and real-time measurement of polymer: results from full-scale treatment plants
Full-scale testing was carried out at two wastewater treatment plants to determine whether residual polymer concentration, measured by filtrate and centrate absorbance at 191 nm, can be used to identify the optimum polymer dose and achieve in-line and real-time dewatering optimization. The first plant uses high speed centrifuges and the second plant uses belt filter presses for dewatering. ...

Digging into the extracellular matrix of a complex microbial community using a combined metagenomic and metaproteomic approach
Knowledge about identity and function of extracellular polymeric substances (EPS) in complex microbial communities is sparse, although these components have a large influence on the function of the microbial communities. We investigated the presence of selected genes potentially involved in EPS production in a 145 Mbp metagenome prepared by Illumina sequencing from a full-scale wastewater ...

Adaptive neuro-fuzzy inference system for real-time monitoring of integrated-constructed wetlands
Monitoring large-scale treatment wetlands is costly and time-consuming, but required by regulators. Some analytical results are available only after 5 days or even longer. Thus, adaptive neuro-fuzzy inference system (ANFIS) models were developed to predict the effluent concentrations of 5-day biochemical oxygen demand (BOD5) and NH4-N from a full-scale integrated constructed wetland (ICW) ...

【Case Study】Great Solution for Septic Tank Sludge Management in Ukraine
Ultra-small VOLUTE Dewatering Press ES-051 largely solves all the costs and maintenance problems. In the year of 2004 in Ukraine, there was no compact sludge dewatering equipment suitable for small-scale wastewater treatment facilities like septic tanks. As for septic tanks, it had been common that liquid sludge was disposed by tanker truck and delivered to central sludge dewatering ...
