  • 4 Benefits Of Electrocoagulation For Arsenic Removal From Water

    In water and wastewater treatment, arsenic is classfied as a heavy metal. It is well known for its toxicity and it can cause numerous health problems in humans if consumed at high enough doses. Arsenic can affect the skin, liver, kidneys, bladder, and prostate as well as the nervous, respiratory, cardiovascular, immune, and endocrine systems. Due to the many health risks associated with arsenic, the U.S. EPA has set the drinking water standard at 10 ppb as the maximum allowable concentration in drinking water. Therefore, this is the goal of all treatment systems for arsenic removal from water.

  • Cost Benefits Of Process Water Disinfection Via UV Light Sterilizer Technology

    For the sake of the productivity and quality of products, as well as the proper upkeep of process equipment, treating process water prior to use is very beneficial, if not vital. One step in treating process water is often disinfection. While there are several chemical options for disinfection, ultraviolet technology can provide several key cost benefits for onsite treatment systems.

  • EPA Researchers Investigate Effectiveness Of POU/POE Systems To Remove PFAS From Drinking Water

    PFAS are a group of synthetic chemicals that have been in use since the 1940s. PFAS manufacturing and processing facilities, facilities using PFAS in production of other products, airports, and military installations are some of the contributors of PFAS releases into the air, soil, and water.

  • Progressive WTP Positions Growing Colorado City For The Future

    Facing source water issues that demanded a new water treatment plant (WTP), the City of Thornton turned to progressive design-build to deliver a modern, flexible fix.

  • Top 5 Drinking Water Issues To Be Resolved

    These comments address five major current topics that U.S. EPA has on its agenda: the Lead and Copper Rule (LCR) proposal, perchlorate, per- and polyfluoroalkyl substances (PFAS), Legionella, and distribution systems. The latter two, Legionella and distribution systems, provide the greatest public health risks associated with drinking water and warrant the highest priorities for management, investments, and health and safety improvements.

  • Wastewater Treatment Plant Realizes The Importance Of Using Genuine Replacement Parts In Its UV Disinfection System (Case Study)

    The UV system installed at the Lucas County Water Resource Recovery Facility includes a total of four banks, with 48 UV lamps per, for a total of 192. The facility was experiencing disinfection inefficiencies and, even after repeated inspection and analysis, staff couldn’t figure out why. They started to question if the issues were stemming from the use of non-OEM, non-genuine UV lamps, quartz sleeves, and ballasts.

  • Understanding PFAS’ Impact On Remediation Strategies

    For more than 16.5 million water-utility customers in 33 different states, contamination caused by per-and polyfluoroalkyl substances (PFAS) is a source-water issue that will not go away for a long time. What are the practical options for community water systems currently confronting this challenge? Here is an overview of several treatments and their relative successes against a wide variety of PFAS compounds.

  • 4 Benefits Of Sodium Zeolite For Drinking Water Treatment

    Use of treatment systems that effectively target and treat toxic and undesirable contaminants is essential to drinking water production. There are typically four stages in a standard drinking water treatment system process, coagulation/flocculation, sedimentation/clarification, filtration, and disinfection. Sodium zeolite is typically utilized in the filtration systems within the filtration stage for optimal treatment performance.

CONTAMINANT REMOVAL SOLUTIONS

  • Aqua ElectrOzone™ Ozone Generation System

    Ozone treatment for water and wastewater has been utilized successfully for several decades and continues to be a viable disinfection solution for both municipal and industrial plants, worldwide.

  • How Activated Carbon Works To Purify Air And Water

    The first step is to define the performance limiting factors in the application. For this application, most of the adsorber is used for MTBE adsorption in the ppb concentration range. Adsorption of BTEX, TBA, or humic acids or other total organic carbon (TOC) components are removed by the front end of the column.

  • PDO evo Ozone Systems

    Ozone is one of the most powerful commercially available oxidants and is commonly used for municipal water and wastewater treatment. In addition to its oxidizing capabilities, it is an environmentally-friendly method of treatment.

  • Pipeline Flash Reactors for Mixing & Contacting

    Pipeline Flash Reactors™ (PFRs or spool pieces) utilize high velocity mixing to transfer ozone or oxygen-enriched sidestreams into bulk water flow, all within a compact footprint. With a PFR, ozone or oxygen mass transfer occurs in the pipeline within seconds, eliminating the need for additional tanks or basins. Whether it is providing ozone for water purification or increased dissolved oxygen for wastewater, Mazzei’s PFR uniformly distributes gas into the water and minimizes the size and cost of gas contacting.

  • BALPURE® Ballast Water Treatment

    The Type-Approved BALPURE® electrolytic disinfection ballast water treatment system is the preferred method of ballast water treatment for LNG/LPG carriers, crude / product / chemical tankers and bulk carriers.
