  • 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 ...

  • Zero-Discharge Treatment System for the Wastewater from Scenic Environmental Sensive Communities

    The “Zero-Discharge” Wastewater Treatment System has been advocated for the scenic and/or historically preserving tourism spots.  The Decentralized Wastewater Treatment (DWT) coupled with the Land Treatment Method has been found to be the most effective treatment system to achieve such historically unachievable “Zero-Discharge” dream. The DWT, normally also referred ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Zero discharge system handles german power station’s fgd wastewater

    Evaporator/Crystallizer Combined with Salt Exchange Pretreatment is the Answer for this Demonstration Plant. The Facility A major European utility has several power block units fitted with wet limestone FGD scrubbers at their 600 MW power station in southern Germany. The blowdown from the scrubbers is treated to remove the heavy metals and suspended solids. The ...

  • How much will a zero liquid discharge system cost your facility?

    With increasing stewardship of environmental protection, both nationally and internationally, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste by implementing zero liquid discharge (ZLD), a process that limits liquid waste at the end of your industrial process to—as the term suggests—zero. A ...

  • Distillation Process Can Yield Zero Liquid Discharge System

    Many industrial applications produce liquid waste as a by-product of their process. As environmental regulations governing the disposal of industrial wastewater become more stringent, it's imperative that innovative wastewater treatment solutions are used to treat this waste and minimize the environmental impact of disposal. While numerous technologies exist to treat industrial wastewater, Zero ...

  • Does your facility need Zero Liquid Discharge Technology?

    If your industrial facility discharges its waste into deep wells, streams, sewers to publicly owned treatment works (POTWs), and/or other waterways, it is likely there are some types of regulations on discharging the waste. With an increasing push toward environmental protection, many industrial facilities and effluent regulators are strengthening strategies to reduce industrial process waste. ...

  • Zero Effluent by Application of Biological Treatment at High Temperature

    For the production of high quality corrugated medium and test liner it has been shown since 1995 at a new large size mill in Germany, that no or practically no effluent discharge is necessary when the process water is treated in an anaerobic/aerobic conventional treatment plant, which is followed by sand filtration. In this paper, three different projects are described which show, that the number ...

  • Reuse of California brine olive oil processing wastewater to meet zero discharge goal

    Abstract Reuse of low strength municipal wastewater is becoming quite common and many technologies are available for that purpose. However, treatment and reuse/recycling of high strength industrial wastewater is still a challenge. In this paper we present some case studies with implemented integrated systems to achieve zero discharge goal. We will concentrate on the description ...

  • Zero Waste to Landfill Goal: Portland Aluminium

     Portland Aluminium has achieved a significant reduction in the amount of waste going to landfill. Although driven primarily by business needs including the pursuit of efficiencies, waste reduction has been achieved by evaluating processes, gaining the commitment of its workforce and combining these efforts with both cleaner production and waste minimisation concepts. ...


  • The The `Design for Autonomous Net-Zero Water Buildings` Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water. The research team ...

  • Pilot-scale demonstration of the hybrid zero-valent iron process for treating flue-gas-desulfurization wastewater: Part I

    The hybrid zero-valent-iron (hZVI) process is a novel chemical treatment process that has shown great potential in previous laboratory and field bench-top scale tests for removing selenium, mercury and nutrients from various industrial wastewaters. In this study, a pilot-scale demonstration was conducted to continuously treat 3.8–7.6 L/min (1–2 gpm) of the flue-gas-desulfurization ...
