  • Emerging Trends In UV Disinfection For Water Treatment

    Introduction The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology.  The acceptance of UV disinfection at water plants ...

  • Photodegradation of chlorpyrifos in water by UV/H2O2 treatment: toxicity evaluation

    Chlorpyrifos (CP) is an organophosphorus pesticide widely used in agriculture. Due to its toxicity, it has been necessary to develop a treatment to eliminate the environmental wastes generated by this substance. The combination of UV radiation and hydrogen peroxide seemed an interesting option to reduce the concentration of CP in water, as it has proved to be a simple and effective method to ...

  • UV set to dominate the municipal industry

    The use of Ultra Violet (UV) light has now become standard practice in most municipal waste water treatment processes. Effluent is now starting to be recognised as a valuable resource, not a problem that needs to be dumped.  Many waste water facilities are being renamed as water reclamation facilities, and whether the waste water is being discharged into a river, being used to irrigate ...

  • The Benefits Of UV Disinfection In The Pharmaceutical Industry

    The quality standards required for purified water in the production of pharmaceuticals have never been stricter, with manufacturers having to conform to an ever increasing number of international standards. Craig Howarth, Managing Director of Hanovia Limited, introduces a number of interesting new developments in UV technology for disinfection and dechlorination. ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • Constructed wetlands combined with UV disinfection systems for removal of enteric pathogens and wastewater contaminants

    Water shortage is an ongoing cardinal issue in the Middle East region. Wastewater reuse offers some remediation, but to-date many rural communities in the Palestinian Authority (PA) and in Jordan are not connected to centralized wastewater treatment plants (WWTPs), many of them are disposing of their wastewater using infiltration septic tanks. This highlights the need for a small, local, low ...

  • Laboratory Study of Conventional Alum Treatment versus MIEX® Treatment for Removal of Natural Organic Matter

    EXECUTIVE SUMMARY In recent years, considerable effort has been made in drinking water treatment research to develop methods with improved natural organic matter (NOM) removal from water. Reduction in the level of NOM before disinfection can minimise the formation of disinfection by-products and reduce the residual required to control bacterial regrowth in the distribution system. This ...

  • 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 ...

  • Introduction to Decentralized Packaged Wastewater Treatment (PWWT) Systems - PDH Article

    Learning Objectives After reading this article, you should understand: Functions and processes of a decentralized PWWT system; Design considerations of a PWWT system. Overview "Clean water will be the oil of the 21st Century." The accuracy and magnitude of this statement is resonating worldwide. ...

  • Ozone Brings Better Bottled Water

    The proliferation of bottled beverages worldwide and an increased awareness of consumer health issues have beverage bottlers rethinking how to keep their liquids safe for consumption. One problem they face is the need to deliver a product that is free of bacteria, to provide extended shelf life and product quality. Ozone has quickly become the disinfectant of choice among water bottlers ...

  • Environmental Industrial Water & Algae Control in lagoons and ponds.

    Proven site trails and report shows a excellent reduction/removal of Microcystis and filamentous algae where we proved excellent results with ASMP-1000.A systems These ponds are characterised by large open lagoons with a fairly high residence time of water and UV exposure in the summer months. During the holding period in the open reservoirs, filamentous algae start growing ...

  • Modification of jar testing protocol combined with mEnCo model predicted dose to predict dissolved organic matter removal for surface water

    In recent climatic events in Australia, the need for frequent jar testing to determine optimum coagulant and flocculant aid doses became apparent in order to determine optimum treatment efficiencies. The generally applied jar test procedure can be time consuming and this prompted investigations for capacity to test waters more rapidly, for a range of treatment conditions and raw water qualities. ...

  • The The `Design for Autonomous Net-Zero Water Buildings` Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water. The research team ...

  • Reclaimed Municipal or Industrial Wastewater for Power Plant Cooling & Boiler Feed Make-Up Water

    For centuries, water was considered a commodity product and used with little or no restriction. In today’s modern society, water is now being considered a precious resource and considerable effort is put into protecting, recycling, and restricting its use freely. State and Federal agencies have put in place guidelines and regulations restricting its use, especially for industrial use. ...

  • City of Albany, NEW YORK

    Since the 1930s, the City of Albany, New York, has used the 200 million gallon Loudonville open-air reservoir as a backup for the city’s primary Alcove reservoir. If the Alcove treatment plant shut downs or a water main breaks, the Loudonville reservoir could supply water to Albany’s 100,000 residents for up to ten days. This system, which uses chlorine disinfection, has served the city well ...

  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...

  • Organics Monitoring (TOC)

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small. Organic Matter Organic ...
