  • Urban wastewater reuse: a pilot plant experience

    The results of a preliminary verification of domestic wastewater reusability in L'Aquila (Italy) are reported. A Tertiary Treatment Pilot Plant (TTPP), rotary filtration and Ultraviolet (UV) Radiation disinfection, was added to an Urban WasteWater Treatment Plant (UWWTP) to test the compliance with water quality indicated for reuse by the enforced Italian regulation. The TTPP was managed varying ...

  • AquaNES: Microbiological monitoring of reused waste water for irrigation of a golf course in Agon-Countainville, France - Case Study

    The Site 9 of the AquaNES project in Agon-Countainville (France) uses secondary effluent after reed bed and sand dune filtration for golf course irrigation in a coastal area. The underlying aquifer is prone to salinization. The study of Agon-Countainville site will demonstrate how innovative water quality monitoring and modelling linked to data management and communication, facilitates an ...

  • Implementation of an automatic and miniature on-line multi-parameter water quality monitoring system and experimental determination of chemical oxygen demand and ammonia-nitrogen

    An automatic, miniature and multi-parameter on-line water quality monitoring system based on a micro-spectrometer is designed and implemented. The system is integrated with the flow-batch analysis and spectrophotometric detection method. The effectiveness of the system is tested by measuring chemical oxygen demand (COD) and ammonia-nitrogen in water. The results show that the modified system ...

  • Water Quality Monitoring for the “Big Four Parameters”

    Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates. For most water ...

  • Google Android mobile phone applications for water quality information management

    This paper introduces some experiences with developing mobile phone demonstrator applications for water quality information management using the Google Android platform. The work presented is part of an EU research project named LENVIS (Localised ENVironmental and health Information Services for all). The applications are focused on delivery of water quality information related to outdoor ...

  • Effects of iron on ecological communities

    Mark and I have been working with the Iron industry to try to understand the effects of iron on aquatic ecosystems. We have been analysing extensive field monitoring data on the quality of invertebrate communities in rivers and relating this to the levels of different forms of iron (total, dissolved, or particulate) that are present. Invertebrate communities do appear to be adversely affected ...

  • A study towards implementation of a standalone environmental monitoring device

    Environment is an issue of major concern all round the world. Protection of environmental resources such as groundwater or marine environment from contamination became an issue of high priority, which requires special consideration. In order to protect the shores water used in desalination and groundwater from various contaminants that may leak from industrial and ship activities, a remote ...

  • Treatment of arsenic-contaminated water using in-line electrolysis, co-precipitation and filtration in Costa Rica

    A novel treatment was tested with groundwater to investigate its arsenic removal under natural conditions. The system utilised in-line electrochlorination to oxidise water constituents without the need for external chemical supply. The oxidised arsenic and iron co-precipitated and were filtered via Greensand Plus™. The filter was catalytically active and provided an emergency oxidant. The ...

  • The potential of lipopolysaccharide as a real-time biomarker of bacterial contamination in marine bathing water

    The use of total lipopolysaccharide (LPS) as a rapid biomarker for bacterial pollution was investigated at a bathing and surfing beach during the UK bathing season. The levels of faecal indicator bacteria Escherichia coli (E. coli), the Gram-positive enterococci, and organisms commonly associated with faecal material, such as total coliforms and Bacteroides, ...

  • Water quality monitoring with online change-point detection methods

    We develop an approach for water quality time series monitoring and contamination event detection. The approach combines affine projection algorithms and an autoregressive (AR) model to predict water quality time series. Then, we apply online change-point detection methods to the estimated residuals to determine the presence, or not, of contamination events. Particularly, we compare the ...
