  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • In the World: Small Mexican village produces clean water with solar-powered system

    MIT-developed system runs autonomously, producing 1,000 liters per day. In a small village deep in the jungles of the Yucatan Peninsula — a day’s drive from any source of clean, drinkable water — researchers from MIT are testing a system that purifies water with the help of the sun. The relatively inexpensive system consists of several modest photovoltaic panels, a large ...

  • The effect of immobilized catalyst structure on the degradation of chemical and biological contaminants in simulated solar photocatalytic water purification

    The performance of different configurations of titanium dioxide-coated foam supports as photocatalysts in an enhanced solar disinfection system for drinking water treatment was evaluated, using the reduction of methylene blue, 1-4-dioxane, and Escherichia coli as performance indicators. Reactors with immobilized catalysts were able to match or surpass the performance of a suspension ...

  • Evaluation of a silver-ion based purification system for rainwater harvesting at a small-scale community level

    Silver has been known for centuries to be a powerful disinfectant, with no known harmful effects to humans if applied in adequate doses. Although its use was partially discontinued with the advent of chlorination and modern antibiotics, the discovery of bacterial resistance and disinfection by-products has enabled its re-emergence as a viable water purification option. On the other hand, ...

  • Numerical simulations of corrosion product activity in the purification system of a typical PWR under nonlinearly rising corrosion and flow rate perturbations

    Numerical simulations of corrosion product activity in the purification system of a Pressurised Water Reactor (PWR) are presented. The computer programme code Corrision Product Activity in Reactors (CPAIR-RC), developed by the authors, has been used to find corrosion product activity in the ion exchanger and filters of PWR under nonlinearly rising corrosion rates and flow rate perturbations. For ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • Recovery of New Orleans Water and Sewer Systems Following Hurricane Katrina

    ABSTRACTHurricane Katrina and its aftermath damaged the water distribution system and the sewerage collection system in the City of New Orleans, creating health and safety issues for both the general public and emergency and recovery personnel working in the city. The efforts by the Sewerage and Water Board of New Orleans (S&WB) in restoring these systems has been critical in making the city ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Power Plant in Thailand Uses Liqui-Cel® Membrane Contactors to Remove CO2 From Water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which canreduce the performance of the system. ...
