  • 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 ...

  • Project profile - arsenic treatment-Michigan

    Background In May, 2003, upon approval by the County Health Department, Adedge Technologies installed the first arsenic treatment system for a Type II nontransient, non-community (NTNC) water system in Oakland County, Michigan. The 40 gallon per minute (gpm) modular system was installed at an elementary school serving 600 students to reduce naturally occurring arsenic to meet the new EPA ...

  • What is zeta potential?

    Zeta potential is a measure of charges carried by particles suspended in a liquid (mostly water). Most particles suspended in water and wastewater, e.g. clays, silica, hydrated metal oxides, paper fibers, biological cells, etc., possess negative surface charges in the neutral pH range as shown in Fig. 1 (a simplified view of a particle in a suspension). The particle is said to carry a negative ...

  • Abrasive wear of piston diaphragm pumps at French WTP results in process change to peristaltic technology - Case Study

    Bredel APEX 20 peristaltic pumps from Watson-Marlow Fluid Technology Group (WMFTG) have replaced piston pumps at a water treatment plant ...

  • Gravity self-backwashing filters

    The filtration of make-up and side-stream water in closed cooling circuits, operated through cooling towers, is a fundamental step to ensure safe and continuous operations in a power plant. Water - required in large amounts for this application - should not be wasted, and the potential damages deriving from a poor treatment must be avoided at all cost. BONO ARTES has developed a technical ...

  • 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 ...

  • Landfarming

    Introduction Landfarming is a full-scale bioremediation technology, which usually incorporates liners and other methods to control leaching of contaminants, which requires excavation and placement of contaminated soils, sediments, or sludges. Contaminated media is applied into lined beds and periodically turned over or tilled to aerate the waste. Soil conditions are often controlled to ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Project profile - technical vocational institute Albuquerque, New Mexico arsenic treatment system

    Background Technical Vocational Institute Community College (TVI) is located in Albuquerque, New Mexico and services approximately 400 students. In 2005, AdEdge Technologies Inc. (AdEdge) was selected to assist in the design of a full-scale arsenic treatment project for the small community system. Detected arsenic concentrations were approximately 26 parts per billion (ppb). The pH ...

  • Low Flow Groundwater Sampling Using RotaPump Inertial Lift Pump

    This article tells you how to perform low flow groundwater sampling using a portable, surface-mounted pump with no decontamination required before each use and  no chance of cross contamination between wells. An inertial lift pump moves a dedicated (stored in the well) pumping tube rapidly up and down.  A one-way valve on the bottom admits water on the down stroke and ...

  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Case study: How to purify Hexavalent Chrome Wastewater

    We all talk about priority pollutants, about hazardous substances and discharge to the atmosphere etc. which are dangerous for our environmental. Day by day we adopt new laws and regulations to protect our green future. So, what is that “priority pollutants”? Priority pollutants are highly toxic chemicals. The list of these chemicals is quite large and includes thousands of items but ...

  • How Does Lead Get into Drinking Water? How Can Local Municipalities Remove It?

    In light of the Flint water crisis—when, in 2014, Flint officials changed the city’s water source from the Detroit Water and Sewerage Department to the Flint River, leaching unsafe levels of lead into the public water supply due to improper treatment—many people are wondering if the same thing could happen in their own communities and homes. Some folks believe this could be the ...
