Green Energy And Decentralized Water Treatment For The Caribbean
Green Energy And Decentralized Water Treatment For The Caribbean

Among water treatment industry professionals, consensus is growing that small- to medium-scale decentralized desalination and wastewater treatment plants are the way forward in a water-stressed future. But governments continue to announce new water mega-infrastructure projects at an alarming rate. Because the public policy debate appears to have simply not caught up with current technology, many companies and NGOs with a focus on small- to medium-scale water treatment or renewable energy have begun to see the Caribbean as something of a new frontier.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Choosing The Right Flow Measurement Technology
    Choosing The Right Flow Measurement Technology

    Flow measurement instrumentation options abound, and the challenge of picking the right one for a particular application can be daunting.

  • Improving Influent Screen Washing For A Fraction Of The Estimated Cost
    Improving Influent Screen Washing For A Fraction Of The Estimated Cost

    The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens is increasing the amount of fecal matter passing through the influent screens, which in turn improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.

  • Contact Lens Becomes Latest Pollutant In Wastewater
    Contact Lens Becomes Latest Pollutant In Wastewater

    The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.

  • Clari-DAF® System Provides Effective TOC Removal For Cambridge WTP
    Clari-DAF® System Provides Effective TOC Removal For Cambridge WTP

    To ensure treated water complied with the most stringent drinking water standards, including the Environmental Protection Agency (EPA) Stage 2 Disinfectants and Disinfection Byproducts Rule (State 2 DBPR), the City of Cambridge, MA, WTP decided to implement a robust multibarrier treatment solution.

  • UV System Provides Safe, Effective Disinfection For Wastewater Treatment Plant On The Hudson River
    UV System Provides Safe, Effective Disinfection For Wastewater Treatment Plant On The Hudson River

    The communities serviced by the Rensselaer County Sewer District, collectively known as the Albany Pool, have combined sewer systems (CSS) that bring stormwater, sewage and industrial wastewater directly to the wastewater treatment facility. When a storm or snow melt results in exceeded capacity, local waterways become contaminated, resulting in a significant environmental challenge, especially in a community where recreational swimming, boating and fishing are popular in warmer months.

    Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  • Case Study: Steel Processor Wastewater Recycle

    The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. By David Christophersen, Technical Support Manager, Veolia Water Technologies

  • Electromagnetic Flowmeter Brings Stability To Potentially Rocky Sand Pumping Application

    Most flowmeters are delivering perfectly accurate results when pumping water. But when you add rocks or sand to the mix, this can figuratively muddy the waters and create noise that leads to instability and false readings

WASTEWATER PRODUCTS

ROMAG™ CSO Screen ROMAG™ CSO Screen

The ROMAG RSW CSO Screen, fitted between the discharge culvert and the relief sewer, reliably retains all visible solids during peak events.

Monster Wash Press Monster Wash Press

JWC Environmental’s Monster Wash Press (MWP) cleans and compacts the discharge from headworks screens, separating water and organics from the solids.  It features a Muffin Monster® grinder to pre-condition screenings before entering the Monster Wash Press.  The grinder breaks open rags, plastics and trash to promote washing and removal of soft organics.  The patent-pending paddle rotor in the active wash zone agitates the material to enhance water penetration throughout the debris for even better removal of the organics from the solids.  Organics are washed back into the wastewater treatment process and the solids are compacted into a dry, less odorous solid plug.  The Monster Wash Press is designed for easy maintenance.  The rotor and field replaceable screen can be removed via the top of the unit, minimizing the clearance space needed around the unit during maintenance.  A grinderless version of the Monster Wash Press is also available.

PASSAVANT® Disc Diffuser ROEFLEX® PASSAVANT® Disc Diffuser ROEFLEX®

The disc diffuser ROEFLEX® stands out for its simple and robust design. It consists of a unique, convex shaped support disc. The disc is covered by a flexible, slotted membrane of elastomer, a ring secures the membrane in place. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, therefore allowing an even distribution of the generated fine bubbles. The membrane can be delivered in different rubber (EPDM) qualities and slot patterns (HL, SL) according to the application.

NIROBOX™ SW NIROBOX™ SW

Containerized seawater desalination solutions ensure water availability in a wide range of applications.

ABB Ability™ For Water Desalination ABB Ability™ For Water Desalination

100% available water in the driest of deserts through highly efficient desalination.

PHOSPHAX™ sc Phosphate Analyzer PHOSPHAX™ sc Phosphate Analyzer

The Phosphate Analyzer is environmentally controlled for rugged, outdoor installations, provides a wide measurement range for a variety of wastewater applications, and comes with the fully featured Plug & Play digital controller.

    How To Provide Effective Disinfection With No Hazardous Chemicals

    Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals.
