Estimating odour impact range of a selected wastewater treatment plant for winter and summer seasons in Polish conditions using CALPUFF model
Odour emission from wastewater treatment plants (WWTP) is a common cause of odour nuisance to neighbouring areas. The analysed object was mechanical biological WWTP designed for 1,200,000 population equivalent. Collection of the samples was carried out in accordance with the methodology described in VDI 3880 and PN-EN 13725 during the rainless weather. Odour concentration measurement was made ...

Operating costs and energy demand of wastewater treatment plants in Austria: benchmarking results of the last 10 years
This work presents operating costs and energy consumption of Austrian municipal wastewater treatment plants (WWTPs) (≥10,000 PE-design capacity) that have been classified into different size groups. Different processes as well as cost elements are investigated and processes with high relevance regarding operating costs and energy consumption are identified. Furthermore, the work shows the ...

Automotive Transmission Manufacturing Plant
Dynatec is engaged to provide a complete WWTP on a design build own operate and maintain basis. The Problem The automotive company was building a new plant in Georgia and required treatment for wastewater for the new plant and needed to reduce their capital expenditures for the new facility. The plant produces wastewater containing oil, metals, and high COD. Further, there was interest in ...

Mathematical modelling of biofilms and biofilm reactors for engineering design
Mathematical models are critical to modern environmental biotechnology—both in research and in the engineering practice. Wastewater treatment plant (WWTP) simulators are used by consulting engineers and WWTP operators when planning, designing, optimizing, and evaluating the unit processes that comprise municipal and industrial WWTPs. Many WWTP simulators have been expanded to include a submerged ...

Design and operating experiences of full-scale municipal membrane bioreactors in Japan
In Japan, membrane bioreactor (MBRs) have been installed in 17 small-scale municipal wastewater treatment plants (WWTPs) in the past 8 years, together with two recently installed MBRs for larger-scale WWTPs. In this study, design and operating data were collected from 17 of them as part of a follow-up survey, and aspects including system design, biological treatment, membrane operation, ...

The Hidden Cost of Tourism on Your Local Infrastructure
How Spikes in Tourism Impact Utilities Like WasteWater Managment In recent years there has been a significant increase in protests against tourists in Europe. A wave of angry anti-British tourist sentiment has peaked across Europe with Spaniards taking to the streets in violent protests as many resorted to anti-tourism slogans and graffiti throughout its tourist hubs. Daily Express, June 5th, ...

Model-based control structure design of a full-scale WWTP under the retrofitting process
The anoxic–oxic (A/O) municipal wastewater treatment plant (WWTP) of Manresa (Catalonia, Spain) was studied for a possible conversion to an anaerobic/anoxic/oxic (A2/O) configuration to promote enhanced biological phosphorus removal. The control structure had to be redesigned to satisfy the new necessity to control phosphorus concentration, besides ammonium and nitrate concentrations ...

Addressing the nutrient crisis: evaluation of a biological filter to meet low total nitrogen discharge limits
New regulations aiming to reduce total pollutant loads entering receiving waters are emphasizing more stringent nutrient discharge limits for wastewater treatment plant (WWTP) effluents. Numerous state Departments of Environmental Quality and Protection have proposed regulations to lower nitrogen pollutant discharge load, especially in environmentally sensitive regions such as the Chesapeake Bay ...

Full scale municipal implementations of the Agar IFAS process for municipal wastewater treatment
Wastewater treatment plant retrofits worldwide are motivated by two main developments: a. Changes in effluent quality regulations, either to more stringent BOD/TSS requirements, or to include nutrient (N and P) removal b. Increase in flows to existing plants, due to either population growth or to expansion of sewerage systems One process capable of giving a cost-effective solution for these ...

Bioaugmentation In Sewer Network Reduces Sludge Production
This article describes the effectiveness of bioaugmentation in the sewer network as a strategy to reduce sludge production. Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing ...

Bioaugmentation in Sewer network reduces sludge production case study
Sludge is an obvious by-product generated from the physical, chemical and biological treatment processes of a wastewater treatment plant (WWTP) as shown in Figure 1. Sludge management, which includes treatment, hauling, and disposal, is one of the biggest burdens facing municipal plants. The costs of sludge management account for 55% of the total WWTP operating cost and 35° o of the capital ...
