Drinking water quality monitoring using trend analysis
One of the common quality parameters for drinking water is residual aluminium. High doses of residual aluminium in drinking water or water used in the food industry have been proved to be at least a minor health risk or even to increase the risk of more serious health effects, and cause economic losses to the water treatment plant. In this study, the trend index is developed from scaled ...

Turbidity tubes for drinking water quality assessments
Turbidity tubes have been considered to be the field method of choice for drinking water quality monitoring in resource-limited contexts because of their relative simplicity and low cost in comparison with conventional (nephelometric) turbidimeters. These tubes utilise the principle of visual extinction of a submerged target for turbidity determination and were therefore thought to be subject to ...

Chlorine mystery solved
Following the installation of in-pipe drinking water quality monitoring sondes, distribution engineers discovered an occasional significant disparity between the Intellisondes’ data and results from grab samples tested by a photometer tablet (DPD) method. For most of the time, there was close agreement between the two methods, but periodically, the photometer results varied wildly, whilst ...

Hydrochemical characteristics of natural water and selenium-rich water resources in the Northern Daba Mountains, China
The Northern Daba Mountains (NDM) of Shaanxi Province, China, are a well-known selenium (Se)-rich area, and the area is also known for endemic fluorine (F) and arsenic (As) poisoning. In order to study the hydrochemical characteristics and trace element contents of the natural waters of this region, 62 water samples were collected from Lan'gao area in the NDM. The hydrochemical composition ...

What are the main indicators of water quality?
“Water is the driving force of all nature;” so said Leonardo da Vinci. The survival of our planet depends on the availability of water and the condition that it is in. It is therefore vital to make sure that it is able to provide a hospitable environment for those that live in it, and is free from harmful levels of substances for those that drink it. Not monitoring water quality ...

Organisational arrangements and drinking water quality
This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

The impact of low-flow season on source drinking water quality, Rosetta branch, Egypt
The present work was conducted to document the problems raised regarding low-flow in the Rosetta branch, Egypt and to develop management options to protect drinking water sources. The water quality was monitored during low-flow periods at four drinking water intakes. Results showed an increase in electric conductivity (EC), ammonium (NH4), nitrite (NO2), phosphate (PO4), and total organic ...

Case Study: WTP Optimizes Well Blending with Online Nitrate Analyzer
The Village of Port Williams is a thriving agricultural community in Nova Scotia, Canada. Like many agricultural communities, long-term fertilizer application to the land has led to elevated levels of nitrate in groundwater. Nevertheless, the local water supply plant continuously produces high quality drinking water. With a reliable nitrate monitoring system from Real Tech and a solid management ...

Australian Drinking Water Guidelines
The Australian Drinking Water Guidelines (ADWG) were developed to provide regulations that ensure drinking water safety. Drinking water under the guidelines is described as water used for human consumption, and it is obtained through a tap or food made using water. It also ensures that water quality meets the intended purpose of use. The National Health and Medical Research Council (NHMRC) works ...

Evaluation of a BWTK for detection of total coliforms,
E. coli and emerging pathogens from drinking water: comparison with standard MPN methodA defined substrate method media in bacteriological water testing kit (BWTK) has been developed to recover and detect the presence/absence of total coliforms and emerging pathogens from drinking water without the need for the confirmatory or complete tests. This method is based on technology that uses a hydrolysable substrate as a specific indicator- nutrient for the target microbes. To perform ...

In-pipe monitors turn dreams into reality
In-pipe monitors turn dreams into reality The quality of tap water has improved enormously in recent decades, but for largely technological reasons, until recently, knowledge of water quality between the treatment works and the tap has been an almost impossible dream for water treatment and distribution network managers. In this article, Jo Cooper, Product Specialist at Intellitect Water, will ...

Home, Sweet Wastewater Building
How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant? A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...
