  • Electrochemical oxidation of two organophosphoric obsolete pesticide stocks

    Organophosphoric pesticides are widely used for crop and fruit tree treatment, but their disposal causes serious environmental problems. Two commercial organophosphoric pesticides (Monocrotophos and Phosphamidon) were treated by an electrolysis system using Ti/Pt as anode and stainless steel 304 as cathode. A number of experiments were run in a laboratory scale pilot plant and the results are ...

  • Ammonium nitrogen removal from wastewater with a three-dimensional electrochemical oxidation system

    Ammonium-containing wastewater could cause the promotion of eutrophication and a hindrance to the disinfection of water supplies. In this study, the feasibility of removing low-concentration ammonium nitrogen from synthetic and real wastewater by electrochemical oxidation was investigated. Using laboratory-scale electrochemical systems, the effects of chloride concentration, current density, ...

  • Application of the central composite design for condition optimization for semi-aerobic landfill leachate treatment using electrochemical oxidation

    In the present study, Electrochemical Oxidation was used to remove COD and color from semi-aerobic landfill leachate collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. Experiments were conducted in a batch laboratory-scale system in the presence of NaCl as electrolyte and aluminum electrodes. Central composite design (CCD) under Response surface methodology (RSM) was applied to ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • ELECTRONIC WATER TREATMENT REDUCES FOULING AND CORROSION IN PIPELINES

    Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...

  • 2015 North American Water Treatment New Product Innovation Award

    Background and Company Performance Industry Challenges Tertiary and advanced wastewater treatment (WWT) is one of three stages in the cleaning of wastewater generated by the municipal and industrial sectors. Building on and improving upon the results of treatment through initial primary and secondary WWT stages alone, tertiary treatment is performed prior to waste ...

  • Removal of arsenic from contaminated groundwater with application of iron electrodissolution, aeration and sand filtration

    The results from a new water treatment system for arsenic removal are presented. The technology is based on the employment of an electrolytic iron dissolution and efficient aeration procedure prior to sand filtration. The treatment was introduced and investigated in a pilot scale plant and full scale waterworks. The pilot scale results showed the potential for efficient arsenic removal from ...

  • Continuous phosphorus removal from water by physicochemical method using zero valent iron packed column

    Excessive phosphorus in aquatic systems causes algal bloom resulting in eutrophication. To treat wastewater including effluent of wastewater treatment plant containing various amounts of phosphorus, a series of continuous experiments on removal of phosphorus from water were performed by using an electrochemical method. The spherical type of zero valent iron (ZVI) and silica sand were packed at ...

  • Treated vs. Untreated Cooling Tower Water: Risks for Your Plant

    When an industrial plant or building decides whether or not to invest in a cooling tower water treatment system, it is a decision that shouldn’t be taken lightly. Petrochemical plants, chemical manufacturers, refineries, and all kinds of large buildings and facilities using cooling towers, whether they’re used as part of the industrial process or for cooling/removing heat from the ...

  • Innovative Approaches to RO Concentrate Management: Beneficial Reuse and Concentrate Minimization

    ABSTRACTDesalination of brackish waters and reclaimed waters using reverse osmosis (RO) is often limited by the options available for concentrate disposal, particularly in inland areas. Dewatering the concentrate is alternative approach to disposal but the available thermal and membrane technologies are still cost prohibitive for most applications. Beneficial reuse of the RO concentrate ...

  • Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It is the corrosion reactions that necessitate ...
