  • Case histories of using tin technology to control corrosion in water systems

    Stannous chloride is an alternative corrosion control in aqueous systems. Stannous chloride’s effectiveness as a better corrosion inhibitor has been demonstrated in both municipal drinking water and industrial cooling water applications and its use has a reduced impact on rivers and streams. Orthophosphate and other phosphate compounds are the most common treatments for reducing corrosion in ...

  • Inhibition effect of phosphorus-based chemicals on corrosion of carbon steel in secondary-treated municipal wastewater

    Secondary-treated municipal wastewater (MWW) could supply a viable alternative water resource for cooling water systems. Inorganic salts in the concentrated cooling water pose a great challenge to corrosion control chemicals. In this study, the inhibition effect of 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP), trimethylene phosphonic acid (ATMP) and 2-phosphonobutane-1,2,4-tricarboxylic ...

  • Iron corrosion as a factor contributing to haloacetic acids formation in the distribution system: experimental assessment and model development

    In this paper, the results of an experimental investigation into four potential explanatory factors (i.e. Fe(II) ions, pH, phosphate and reaction time) with different levels, and their influence in the formation of haloacetic acids (HAAs) in water samples are presented. This study revealed that Fe(II) ions (p = 0.0001), phosphate based corrosion inhibitor (p = ...

  • Crossflow Membrane Applications for Glycol-based aqueous solutions

    Introduction This document is a guide for water treatment engineers to better understand crossflow membrane applications for glycol-based aqueous solutions. It includes glycol applications we have sold equipment for, applications we have successfully tested, and applications we have not tested but are expected to be technically feasible. Glycol-based solutions are commonly used by a ...


  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels ...

  • Cooling Tower Blowdown Water

    Comparison of electrolytic oxidation v. ozone as biocide and reducing rate of TDS build-up in Cooling Tower Blow Down Water. Performed by Pureflow PtY Ltd of Singapore at Singapore Polytechnic Institute. Open evaporative cooling systems have been widely used throughout industry to remove heat from process systems and modern buildings for the purpose of air conditioning. As a result, due to this ...


  • Metals and Related Substances in Drinking Water

    The contamination of drinking water by metals and metalloids can occur throughout the “source to tap” production and delivery system. The major problems are with arsenic, iron, nickel and lead. Problems can also occur with aluminium, copper, manganese, selenium and sodium. Arsenic, iron and lead are core parameters in the UN/WHO Protocol on Water and Health. The spectrum of ...

  • Effects of phosphorus on biofilm disinfections in model drinking water distribution systems

    Drinking water biofilm development is affected by the available nutrient levels and the presence of disinfectants. Phosphorus is recognized as another important limiting nutrient besides organic carbon. In this study, drinking water biofilms were developed in annular reactors to examine the effects of phosphorus on the biofilm disinfections with free chlorine and monochloramine. Phosphorus ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • 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 ...

  • Phosphonate removal from discharged circulating cooling water using iron–carbon micro-electrolysis

    Phosphonate is a commonly used corrosion and scale inhibitor for a circulating cooling water (CCW) system. Its discharge could cause eutrophication of receiving waters. The iron–carbon (Fe/C) micro-electrolysis technology was used to degrade and remove phosphonate from discharged CCW. The influences of initial pH, Fe/C ratio (FCR) and temperature on phosphonate removal were investigated ...

  • 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 ...

  • What Is a Cooling Tower Water Treatment System and How Does It Work?

    For industrial companies using a cooling tower for its facility, some type of cooling tower water treatment system is usually necessary to ensure an efficient process and long equipment service life.
