  • Minnesota debates phosphorus discharge limits for improved water quality

    City leaders across the Minnesota River Basin are protesting proposed phosphorus standards, which they contend will be too expensive and have little or no effect on water quality. In January, 41 of the 147 Minnesota cities in the basin outlined their objections in a letter to the governor and the Minnesota Pollution Control Agency. Many of these cities’ wastewater treatment plants ...

  • The Ganges water-sharing treaty: risk analysis of the negotiated discharge

    Bangladesh and India have resolved the Ganges water-sharing problem by signing a thirty-year treaty in December 1996. Both countries share the dry season (January-May) discharge of the Ganges River at Farakka, West Bengal, India. The sharing season is divided into fifteen 10-day cycles. The treaty is based on the discharge of the Ganges at Farakka over the period 1949-1988, taking the average ...

  • A four-step guide to accurately calculating surface water discharge

    Today, a wide range of government agencies, municipalities, utility companies, and private companies need to monitor water flow in rivers, streams, and canals for a variety of reasons ranging from predicting water availability and flood events to allocating water resources and planning for future development. At a high-level, these organizations are concerned with the water flow and discharge of ...

  • Skimmer with rolling stand helps prevent oily water discharge

    Despite continuous replacement and upgrading of fittings, it is difficult to entirely eliminate hydraulic and lubricating oil coming from machines during normal operations and maintenance activities. This oil ends up in different pits used to collect wastewater throughout the plant. Because of high oil content, city officials would not allow plant wastewater to enter the Longmont sanitary sewer ...

  • Surface water quality management using an integrated discharge permit and the reclaimed water market

    Water quality trading is a sustainable framework for surface water quality management. It uses discharge permits to reduce the total treatment costs. For example, the case of Gharesoo River in Iran shows that the nitrogen permit market between point and non-point sources is 37% more economical than the command and control framework. Nevertheless, the cost saving may be reduced to ...

  • An integrated approach to the optimisation of water usage and discharge in pulp and paper plants

    This paper is aimed at developing a systematic methodology for the cost-effective reduction of water usage and discharge in pulp and paper plants. As the industry moves towards increased system closure, the build-up of Non-Process Elements (NPEs) leads to serious consequences on the process equipment. In response, this paper achieves the following: a mathematical model to track water and primary ...

  • Fibra™ lets Tarmac reuse water & meet EA discharge requirements

    Innovative Features Following a period of continuous growth, full-scale FibraTM filters have been installed at two Tarmac pre-cast concrete sites for removal of contaminants from wastewater. The solution has proven particularly effective at other similar sites and other comparable industrial applications. These industries have traditionally discharged the wastewater to sewer because it has ...

  • Best management practices (BMPS) for discharging water from a construction site

    Having problems on your job site with regulations related to pumping water from your site? Discharge water may carry harmful compounds that can, and have affected our water quality and the ecosystem, hence the environmental agencies concerns. When pumping from dewatering systems, storm water management ponds (SWMPs), excavations or trenches, or any form of surface runoff, BMPs are needed to ...

  • Water depth effects on initial dilution of horizontally discharged cold water from an elevated outfall

    In this study, the effect of bottom depth interaction on initial dilution differences of cold water discharge was experimentally investigated. 5°C cooled and dye tracer added cold water were horizontally discharged from a submerged circular nozzle from an elevated position into a stagnant and homogeneous receiving water in an experimental tank. Minimum initial dilutions were measured in cold ...

  • VSEP helps meet discharge guidelines, recycles water and improves mine economics

    Since their development as lab filters in the early 1960s, polymeric membranes have grown in the number of uses at exponential rates. Membrane architecture and process design itself has undergone significant advancement. A unique membrane filtration system, known as V✧SEP (Vibratory Shear Enhanced Process), was developed by New Logic of Emeryville California. The technology employs ...

  • Potential health implications of water resources depletion and sewage discharges in the Republic of Macedonia

    Potential health implications of deficient sanitation infrastructure and reduced surface water flows due to climate change are examined in the case study of the Republic of Macedonia. Changes in surface water flows and wastewater discharges over the period 1955–2013 were analyzed to assess potential future surface water contamination trends. Simple model predictions indicated a decline in ...

  • VSEP recovers fuel and creates a clean water stream that exceeds discharge requirements

    Fuel storage tank bottom water (FSTBW) is one of several types of petroleum contaminated wastewater sources that can be treated using V✧SEP technology. The source of FSTBW, as suggested by its name, is simply water that separates from petroleum products that are being stored and transported in large quantities. This water that is periodically removed from the storage tanks in order to be ...
