  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Why septic treatment systems fail to reduce nitrogen in US residential areas

    The US EPA in cooperation with various state, academic, and NGO agencies has been involved in field tests throughout the eastern United States of conventional and advanced septic systems in order to determine “best” design for the reduction of total nitrogen (as a combination of ammonia-N plus nitrite+nitrate-N), phosphorus, and coliforms for residential (single and multifamily) septic systems ...

  • Water Savers

    With record-breaking droughts, rising temperatures and more than half of the United States population living in cities with vulnerable water supplies, water scarcity has gone from distant doomsday scenario to a natural resource reality. But at 98 gallons of water per person, the United States’ daily water use is among the highest of any nation in the world, over seven times the 13.2 gallons ...

  • Beyond the barriers of water reuse

    Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked. An answer can be found in the ways that we apply membrane bioreactor (MBR) technology. As one of the most central components for water ...

  • 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 ...

  • Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

    There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Aligning theory and measurement in behavioral models of water conservation

    Discussion in the water literature has called for research on the role of behavioral intentions in explanations of both water demand and water conservation. But previous research has suggested that individual-level motivations are not good predictors of metered household water consumption. Two possible reasons for the lack of association between intentions and actual water conservation are that: ...

  • Piedroba Dewaters Slurry, Returns Clean Water to Holmes Beach Canals

    This project was a successful application of a total cleaning system (TCS), where the particular type of solids of the sediments permitted the dredger to avoid the costly construction of a dredged material maintenance area (DMMA), or the transportation and tipping fees for a municipal landfill. The surface waters were cleaned in tandem, and contributed to a higher quality benthic environment in ...

  • Case study - Algae control in New Jersey raw water reservoir

    Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. The four buoys operated for five months in the spring/summer 2014. The Challenge: Address Episodic Taste and Odor Events The primary objective of this project was to ...

  • 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 ...

  • The Effects That Well Depth and Wellhead Protection Have on Bacterial Contamination of Private Water Wells in the Estes Park Valley, Colorado

    Over the past five years, it is estimated that 10% of residential water wells have tested positive for total coliform and 2% for E.coli bacteria in the Estes Park Valley, Colorado. Many of these water wells are shallow or hand-dug in construction. In this study, samplings of 30 private untreated water wells were tested for total coliform bacteria in the Estes Park Valley.
