  • 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 ...

  • 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 ...

  • Five common problems with zero liquid discharge and how to solve them

    As more and more facilities are turning to zero liquid discharge (ZLD) for wastewater treatment and effluent reduction—whether it’s to comply with local discharge regulations or recycle and reuse as much water as possible in your process—more information is becoming available about the possible issues your facility might face while using ZLD technology. Because of the scope of ...

  • 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 ...

  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • 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. ...


  • Top ten technologies for 2007

    Technology breakthroughs continue to come with what appears to an exponential rate. Some 30 years ago, recycling wastewater from a manufacturing operation and 'zero' discharge were no more than a dream. A fine filter was something that was used only in laboratories by qualified technicians. If you had organic emissions, they were burned in flares, not RTOs. We no longer have to use boilers and ...

  • Corrugator Sheet Plant 1

    A facility that made corrugated sheet board was using a specialty flocculant to treat their wastewater. Unfortunately, it treated the water only one half of the time to acceptable levels for reuse as starch makeup. The facility had paid $45,000 in the first 6 months of the year in chemical costs and $40,000 in haul-off costs to haul the majority of the treated water offsite. Integrated Engineers, ...

  • Enel power, italy – brindisi project – ZLD plant for FGD wastewater treatment

    The Facility The Brindisi Sud Power Plant is equipped with four coalfired units each of 660 Mwe capacities. These units normally fire imported coal with < 1% Sulphur. The flue gases are treated sequentially by SCR-DeNOx with ammonia as reagent, High efficiency ESP to remove fly ash and wet limestone gypsum forced oxidation DeSOx. Each unit is equipped with a 2 x 50% DeSOx lines each ...

  • Integrated process control for recirculating cooling water treatment in the coal chemical industry

    This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...
