  • The mystery of electronic water treatment unveiled

    The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

  • How green is your supply chain?

    Over the past ten years, protection of the environment has become a household concern and an industrial priority. Concerns about industrial pollution are often linked with the production of industrial waste and high energy usage. However, not just industry but all businesses have an environmental impact – even within the office environment there may be significant emission of greenhouse gases and ...

  • Preventing Rust Formation with Electronic Water Treatment

    The growing demand for water for industrial applications, power production and water supply has resulted in an increasing need for water treatment. The water used in industry comes from a range of sources such as rivers, lakes, wells and oceans and contains dissolved and suspended solids.  In addition the industrial world has to reuse water which in turn causes it to be highly concentrated ...

  • Electronic Water Treatment Reduces Fouling In Reverse Osmosis

    Reverse Osmosis (RO) is used in processes requiring high-quality, purified water, such in semi-conductor processing or biochemical applications and can be used to treat boiler feed water, industrial wastewater or process water. A water purification technique, it reduces the quantity of dissolved solids in solution. RO uses waterline pressure together with energy consuming pressurizing pumps that ...

  • 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. ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Simulation of space vector PWM inverter supplied from photovoltaic array

    This paper presents simulation models of space vector PWM (SVPWM) inverter supplied from photovoltaic (PV) array using two different modelling approaches: circuit-based model and mathematical model. The models are developed in Matlab/Simulink and SimPower System toolbox. The realised simulation models are stable and account for various operating conditions including balanced and unbalanced ...

  • Recycling Computer Waste: A Revolutionary Idea to Reduce Electronic Waste

    Time and again, we often come across words like Reduce, Reuse and Recycle. Let’s face it, being a consumer, we deal with daily stuff which could be recycled and reused. The garbage which we throw into dustbin could contain various types of products which could be recycled and reused but we are not quite aware about which products could be recycled. Electronic waste is one such type of waste ...

  • Electronic Water Treatment - An alternative solution to removing beerstone and limescale

    Beer contains 90% water and is the most important ingredient in determining its flavor.  Water contains calcium and is the most important mineral to the brewing process.  The levels of calcium in local water have determined the type of beer produced.  The different types of beer whether a light lager or a porter are for the most part due to the water profiles of the areas that made ...

  • DSTATCOM for power quality improvement in a four-wire electric distribution system

    This paper deals with the simulation of a Distribution Static Compensator (DSTATCOM) for power quality improvement in a four-wire electric distribution system. A three-phase Insulated Gate Bipolar Transistor (IGBT)-based Current-Controlled Voltage Source Inverter (CC-VSI) with a DC bus capacitor is used as a DSTATCOM. The DSTATCOM improves the supply power factor, eliminates harmonics, provides ...
