Case Study: Liz Bagshaw on the IRC sensors

by Partech (Electronics) Ltd.  (Jul. 13, 2015)

Our infrared IR’C sensors have been making waves in the world of glacial meltwater monitoring. Glacial environments are key indicators of global warming and climate change. They’re also home to a diverse range of microorganisms. Both of these need to be quantified and monitored, but doing this isn’t easy because of the cold, ...

Predictive water quality modelling and resilience flow conditioning to manage discolouration risk in operational trunk mains

by IWA Publishing  (Aug. 6, 2015)

This paper presents predictive discolouration modelling and subsequent field trial validation for a cast iron trunk main network. This enabled a UK water company to propose an ‘operational flow conditioning’ maintenance plan that reduces discolouration risk, improves network resilience and asset condition and yet does not require ...

The use of simulated rainfall to study the discharge process and the influence factors of urban surface runoff pollution loads

by IWA Publishing  (Jul. 24, 2015)

An understanding of the characteristics of pollutants on impervious surfaces is essential to estimate pollution loads and to design methods to minimize the impacts of pollutants on the environment. In this study, simulated rainfall equipment was constructed to investigate the pollutant discharge process and the influence factors of urban surface ...

Efficiency and reliability of membrane processes in a water reclamation plant

by IWA Publishing  (Jun. 26, 2015)

Performance of a water reclamation plant using ultrafiltration (UF) and reverse osmosis (RO) treating 280,000 m3/d of wastewater was evaluated over 1 year. Statistical analyses were performed on flow rate, temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), biochemical oxygen demand (BOD5) and total coliforms. Variations ...

Cape Preston Project - The first Pre-Assembled Large-Scale Desalination Plant case study

by IDE Technologies  (Jun. 24, 2015)

The Cape Preston desalination plant is the world’s first large-scale desalination plant that was pre-assembled elsewhere due to the remoteness of the location. It provides high quality clean water to CITIC Pacific Mining’s Sino Iron project, overcoming a number of extraordinarily difficult environmental challenges. ...

Enhanced nitrogen removal with an onsite aerobic cyclic biological treatment unit

by IWA Publishing  (Jun. 12, 2015)

Coastal Zone Act Reauthorization Amendments (CZARA, Section 6217) necessitate the requirement that onsite wastewater disposal units located near impaired surface waters or groundwater to provide at least 50% nitrogen removal. Approximately 38% of Hawaii households use onsite systems including septic tanks and cesspools that cannot ...

Point-of-use chlorination of turbid water: results from a field study in Tanzania

by IWA Publishing  (Jun. 8, 2015)

Household-based chlorine disinfection is widely effective against waterborne bacteria and viruses, and may be among the most inexpensive and accessible options for household water treatment. The microbiological effectiveness of chlorine is limited, however, by turbidity. In Tanzania, there are no guidelines on water chlorination at household ...

Anaerobic biological treatment of methylparaben in an expanded granular sludge bed (EGSB)

by IWA Publishing  (Jun. 3, 2015)

This study evaluated the behavior of an anaerobic expanded granular sludge bed system using different methylparaben (MPB) concentrations. The assay was conducted for 268 days and was divided into seven stages of operation, which included the starting stage and subsequent stages where the MPB concentration was increased. The inoculum that was ...

What is TDS?

by Camlab Limited  (May 30, 2015)

Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule ...

An investigation into the effectiveness of sand media amended with biochar to remove BOD5, suspended solids and coliforms using wetland mesocosms

by IWA Publishing  (May 18, 2015)

Constructed wetland ecotechnologies (CWEs) are a promising solution to effectively treat domestic wastewater in developing countries at low cost. This paper reports the findings of the effectiveness of sand media amended with woody biochar and two plants species (Melaleuca quinquenervia and Cymbopogon citratus) in removing biological oxygen ...
