Dissolved and colloidal organic nitrogen removal from wastewater treatment plants effluents and reject waters using physical–chemical processes

by IWA Publishing  (Aug. 7, 2014)

Four physical–chemical processes were compared in terms of the efficiencies of dissolved and colloidal organic nitrogen (DON and CON) removal from the secondary effluents (SE) and reject water from full-scale biological nutrient removal activated sludge systems. Adsorption on activated carbon was most efficient and allowed removal from the ...

Major waste management company and cbio combine resources, to resolve a breach of ammonia consent, in a large wastewater treatment plant case study

by Cleveland Biotech Ltd  (May 29, 2014)

The WWTP itself is located in the East Midlands, and treats dairy waste from a large processing plant, treating c1,500m3 of effluent per day. On 30th July the ammonia (NH3) levels in the permeate from the MBR at the plant began to increase. The effluent plant discharges to a river and as such, the consent limit is stipulated by the Environment ...

Multispecies acute toxicity evaluation of wastewaters from different treatment stages in a coking wastewater‐treatment plant

by John Wiley & Sons, Ltd.  (Jul. 9, 2014)

Coking wastewater contributes approximately 5% of the total discharge volume of industrial wastewaters every year in China. The toxicity of coking wastewater to aquatic organisms is still unknown. The authors evaluated the toxicity of wastewater from different treatment stages in a coking wastewater treatment plant, South China, using 5 test ...

Organic matter removal during pilot-scale soil aquifer treatment for domestic wastewater in the tropics

by IWA Publishing  (Aug. 7, 2014)

The potential of enhancing water uses using soil aquifer treatment (SAT) is an interesting alternative for tropical regions, limited only by lack of knowledge on its performance in local conditions and the feasibility of adapting this technology. A SAT pilot study was conducted to analyze the phenomena associated with the transformation of ...

Swedish Biogas Plant Case Study

by Biodome International Ltd  (Jun. 5, 2014)

BIODOME® INTERNATIONAL has success-fully installed a BIODOME® Double Mem-brane Roof onto a GFS Tank for a Swedish Biogas Plant. The waste-to-energy facility was a partner-ship between renewable energy specialist Swedish Biogas International and the City of Flint. The additional digester was added to the existing waste water treatment ...

Thermal hydrolysis of waste activated sludge at Hengelo Wastewater Treatment Plant, The Netherlands

by IWA Publishing  (Jul. 16, 2014)

The thermal hydrolysis process (THP) is a sludge treatment technique which affects anaerobic biodegradability, viscosity and dewaterability of waste activated sludge (WAS). In 2011 a THP-pilot plant was operated, connected to laboratory-scale digesters, at the water board Regge en Dinkel and in cooperation with Cambi A.S. and MWH Global. Thermal ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

by Gasmet Technologies Oy  (Apr. 16, 2014)

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse ...

Dissolved radionuclide in the industrial effluent of uranium facilities, Jaduguda, India

by Inderscience Publishers  (May 23, 2014)

Dissolved radionuclides in the effluent of uranium mining industry were studied. Activity concentrations of uranium and radium were estimated in effluent water from different uranium mines and mill tailings ponds. The concentrations of U and 226Ra in untreated effluent water were found to be elevated. The concentrations of dissolved radionuclides ...

Denmark’s Near-Zero-Waste Wonder

by Ensia  (Jul. 21, 2014)

Has this Danish community found the formula for environmentally friendly industry? When we look closely at systems in nature — coral reefs or rainforests, for instance — we see something we don’t often see in human systems: mutually beneficial relationships and energy flows among the various elements, such as air, water, rocks, ...
