  • Decontamination of a natural multicomponent aqueous liquid waste by titania photocatalysis

    The aerobic photocatalytic degradation of municipal dump-site leachate at 300 K has been carried out in a pilot-scale bubble column reactor. The leachate feed is a complex mixture of various organics and nitrogenous compounds. Runs were performed over a 48-hour period at atmospheric pressure. Compositional analysis of aliquots from the reactor revealed simultaneous total organic carbon removal ...

  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...

  • Automotive Manufacturer Achieves Zero-Liquid-Discharge Production, Recovers Waste Energy - Case Study

    An automotive manufacturing plant in Morocco, consisting of pressing, body assembly, paintwork, and final assembly, started-up in early 2012 with two new production lines and an annual output capacity of 400,000 vehicles/year. The site was designed to discharge zero industrial effluents to the environment. Water consumption for manufacturing processes are 70% lower than for a conventional plant ...

  • Waste Disposal

    Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

  • 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 ...

  • 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 ...

  • Waste Management Overview

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • How to Deal with Drilling Waste

    At present, environmental protection is a basic state policy in China, and it has been a strategic mission and goal for our country to maintain a sustainable development of society, economy and environment. Along with the continuous improvement of environmental laws and the increasing environmental awareness among people, the departments concerned have successively enacted various environmental ...


  • Impact of Non-Aqueous Phase Liquids (NAPLs) on Groundwater Remediation

    Nonaqueous Phase Liquids (NAPLs) are immiscible (undissolved) hydrocarbons in the subsurface that exhibit different behavior and properties than dissolved contaminant plumes. NAPLs have a tremendous impact on the remediation of contaminated aquifers, as it is very difficult or impossible to remove all of the NAPL from a hazardous waste site once released to the subsurface. Although many NAPL ...


  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

  • 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 ...
