  • Case study - Discharge measurement at the river

    Due to the seasonally strong weed growth and low flow during low water periods the measurement of water level and flow at the measurement site "Kleinraschuetz“ was rather distorted. It had to be corrected by putting in additional manpower for manual measurements. Therefore it was decided to modernize the station completely and to install a stationary discharge measuring system. The ...

  • A zero discharge installation for Mondi Packaging

    Answering the request of Mondi Savoie  (La Rochette), ECA (Environnement et Chimie Appliquée), worked-out a technico - economical survey on the several treatments, recycling and/or valorisation solutions for its flexo printing and starch glue effluents. After this study, ECA defined and realized a zero discharge installation treating the water fluids. Mondi Savoie, one of the French factories of ...


  • Corrugated Printing Facility Zero Discharge

    This company imports corrugated board and prints the labels using a flexographic machine. The facility had a wastewater treatment system using the traditional liquid chemistry of aluminum chloride, caustic for pH adjustment, and an anionic flocculant. The effluent was often out of compliance due copper from the color pigments in the inks. The system required continual adjustment of the 3 ...

  • Confined plasma gliding arc discharges

    A confined plasma gliding arc is produced in a reactor with two-electrodes contained within a very narrow channel and water spray injected into the discharge. The evolution of pH and conductivity and the formation of hydrogen peroxide in pure water with different carrier gases and the decolourisation and mineralisation of an organic dye were compared with results for a non-confined ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
