  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Selection and design criteria of supported liquid membrane for the treatment of rad-waste

    Supported Liquid Membrane (SLM) is an emerging trace metal pre-concentration technique. It has the ability to decontaminate radionuclides even from lean secondary effluent. SLM can be considered as a part of process intensification, which implies a closed loop operation. It has reduced space requirement as well as minimised secondary effluent generation and the number of unit steps. Proper ...

  • Membrane treatment of liquid wastes from radiological decontamination operations

    The paper focuses on the evaluation of membrane filtration for the treatment of liquid radioactive streams generated in area decontamination operations. In this work, semi-permeable membranes were demonstrated to be effective reducing the volume of wastewater containing cesium and cobalt by two orders of a magnitude. The efficiency of membrane separation was enhanced by employing additives that ...

  • Treatment Alternatives for Liquid Penetrant Rinse Waters

    Explores the options available to process wastewater generated from liquid penetrant inspection. Rinse waters containing residues from the penetrant inspection process are generated from all but Method C (solvent removal).  The rinse water contains penetrants (Method A), or penetrants and emulsifier (Methods B and D), which contain oils and surfactants.  The water may also contain ...

  • STEP - System for Solid and Liquid Waste Put to the Test

    Wendy Laursen details the System for Environmental Protection (STEP) system which is being installed inside a twenty-foot ISO container to be trialled onbard the Canadian Coast Guard vessel, Pierre Radisson.   The STEP container houses Terragon's single-drum Micro-Auto Gasifciation System (MAGS) and Wastewater Electrochemical Treatment Technology (WETT).  MAGS aims to ...

  • Evaluation of second-generation Multistage Wastewater Treatment System for the removal of malodors from liquid swine waste

    Wastewater quality and malodors in a second generation implementation of environmentally superior technology (EST) were monitored over three cycles of pig (Sus scrofa) production and 15 mo. The wastewater treatment system consisted of three modules: solids separation, biological N removal, and P recovery/wastewater disinfection. While approximately more than 90% of the wastewater suspended solids ...

  • Experiences with anaerobic treatment of fat-containing food waste liquids: two full scale studies with a novel anaerobic flotation reactor

    Fat-containing food waste can be effectively treated in a new type of reactor, the so-called BIOPAQ-Anaerobic Flotation Reactor or BIOPAQ® anaerobic flotation reactor (AFR). In the reactor a flotation unit is integrated to retain the sludge. In this study results from two plants with a 430 and 511 m3-AFR, respectively, are presented. In one reactor, which is fed with water ...

  • Waste Water Treatment Processes Explained

    SUNCOAST WASTE WATER MANAGEMENT  presents  AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

  • Pumping Polyelectrolyte in waste water treatment

    The Challenge An industrial waste water treatment company required a cost effective solution to pumping polyelectrolyte. The plant engineers approached Verderflex distributor, Global Pumps Australia, for a solution to the following problems: Existing helical rotor pumps were expensive to run and maintain The replacement pump would have to be able to ...

  • AVA Technology for Hazardous Waste Treatment - Case Study

    AVA has developed systems for pre-treating hazardous waste prior to incineration, which leads to higher throughput performance in combination with lower construction and maintenance costs and additional low pollution emissions, in comparison to conventional techniques. The system is based on the principal that constant gross calorific values and regular piece sizes together with consistency of ...
