  • PFAS Destruction Through Supercritical Water Oxidation

    Despite several states taking action against PFAS, satisfying solutions to destroy the forever chemicals have been out of sight. However, a Danish company has taken up the fight, and the proven full-scale solution based on supercritical water oxidation (SCWO) presents promising results.

  • Inactivation Of SARS-CoV-2 Virus With Preservation Buffer B

    Read the full white paper to learn how testing was performed to confirm that the Preservation B reagent used in LuminUltra® SARS-CoV-2 Environmental Monitoring Kits inactivates the SARS-COV-2 virus to ensure safe handling of samples throughout the assay.

  • Monitoring Strategies For Controlling Legionella Growth In Water Systems

    Legionella is a genus of bacteria that are found widely in aquatic environments, particularly in constructed water systems with warm temperatures. These bacteria are known for causing Legionnaire’s Disease and Pontiac Fever. This whitepaper focuses on monitoring strategies that can be used as a component of a water management plan for controlling Legionella growth in various types of water systems (cooling towers, hot water, potable water, etc.) and reducing associated risks.

  • Calcium Hypochlorite Feeder Selected As Primary Solution For Municipal Water Treatment Plants

    Long Beach Township is the largest town on Long Beach Island, New Jersey. With 18 miles of beaches, the town is a major tourist destination. Population exploded during the summer months from approximately 3,000 to over 100,000. This can be a challenge for the town's drinking water facilities, with demand increasing exponentially during the tourist season.

  • Byers Gains Stable Chlorination And Reduced Maintenance With Constant Chlor® MC5 System

    Byers is an unincorporated rural community in Arapahoe County, Colorado, approximately 50 miles east of Denver. Byers Water & Sanitation District provides drinking water to this area. The district operates five wells – each approximately 700 feet deep. Two wells are typically used in the winter and four in the summer. Annual water use averages 140,000 gallons per day for the district’s 500 active service connections.

  • Biofouling Control In Cooling Towers With A Halogen Stabilizer

    Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

  • Breaking The Causative Chain Of Legionellosis

    Legionnaires’ disease first garnered public attention in 1976. After attending an American Legion convention at a Philadelphia hotel, 221 people became ill, with 34 dying of a mysterious illness. The U.S. Centers for Disease Control and Prevention (CDC) launched a major investigation, and in 1977 identified the responsible bacterium, naming it Legionella.

  • Growth Opportunities Are On The Horizon In The Water And Wastewater Treatment Equipment Market As Public Concern On PFAS Rises

    Per- and polyfluoroalkyl substances (PFAS) are a family of ever-expanding, complex man-made compounds that have leached into our soil, air, and water. There are nearly 5,000 different types of PFAS found in various products like nonstick cookware, food packaging, cleaning supplies, paints, waterproof jackets, firefighting foams, carpets, and more.

  • The Highly Consolidated U.S. UV Water Treatment Equipment Market

    The U.S. ultraviolet water (UV) water treatment equipment market for industrial and drinking water applications is competitive, mature, and saturated. The market is dominated by a few leading players holding significant market shares.

  • Understand The Risk Of Stagnant Water To Reopen With Safety And Reliabilty

    The year 2020 has marked a time when the risk of disease has altered plans for how we work, shop, learn and travel. As the work force re-enters offices and more industrial and commercial facilities reopen, there looms another risk waiting in our water systems – Legionella.

CONTAMINANT REMOVAL SOLUTIONS

  • 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.

  • Capital Controls® Model T70G4000 Chlorine Dioxide Generator

    The Model T70G4000 chlorine dioxide generator is designed to produce and consistently maintain a product yield greater than 90%, which makes it ideal for drinking water treatment. It is a two chemical system, utilizing commercially available concentrations of hydrochloric acid and sodium chlorite in the production of chlorine dioxide. No chlorine gas is required. A proven design, durable construction and the use of the best available corrosion-resistant materials assure efficient gas production, precise solution feeding, low maintenance and dependable operation for the life of the equipment.

  • Pressure Filters

    Loprest pressure filters can be provided in horizontal or vertical vessel configurations for flow rates from 50 to 5,000 GPM. The Loprest multi-cell pressure filter design produces its own backwash water, so there is no need for a separate treated water source and pumping system. The Loprest filter design has been optimized over many years for reliable, efficient, economical operation. All Loprest treatment systems are operated by a fully automated control package.

  • ChlorMaster® On-Site Sodium Hypochlorite Generation Systems ChlorMaster seawater systems are commonly used in coastal and offshore installations such as power plants, desalination plants, and oil drilling and production facilities. They effectively control slime and marine organism growth in condenser cooling water, circulating water and service water systems.
  • Chemical Feed Systems

    IMS Chemical Feed Systems are pre-assembled, fully-functional chemical delivery systems for water treatment applications. These compact, user-friendly chemical skids include local storage tanks, full secondary containment, dosing pumps, instrumentation and controls. Systems are piped and wired at the factory for easy and quick hook-up.

CONTAMINANT REMOVAL VIDEOS

This talk is on coagulant dose management and focuses on the challenges facing those watershed areas impacted by wildfires. Keeping up with the pre-treatment process can be difficult and changes to source water run-off may last for some time. Several factors impacting water treatment during and after wildfires are discussed.
