Comparison between the coagulants surfactant modified bentonite, combination chitosan-natural bentonite and combination chitosan-modified bentonite for peat water treatment
Peat water is an abundant water resource in Asia, especially in rural areas. However, it is unsuitable to be used as a commercial water supply. Monitoring peat water characteristics at Beriah swamp, Perak, recorded colour (238 PtCo), turbidity (12.86 NTU), iron (0.89 mg/L), pH (4.8) and chemical oxygen demand (COD) (27 mg/L) over the national limitation standards. In this study, surfactant ...

National rural drinking water monitoring: progress and challenges with India's IMIS database
National drinking water programs seek to address monitoring challenges that include self-reporting, data sampling, data consistency and quality, and sufficient frequency to assess the sustainability of water systems. India stands out for its comprehensive rural water database known as Integrated Management Information System (IMIS), which conducts annual monitoring of drinking water coverage, ...

The challenge of global water access monitoring: evaluating straight-line distance
versus self-reported travel time among rural households in MozambiqueSupport is growing for the incorporation of fetching time and/or distance considerations in the definition of access to improved water supply used for global monitoring. Current efforts typically rely on self-reported distance and/or travel time data that have been shown to be unreliable. To date, however, there has been no head-to-head comparison of such indicators with other possible ...

Profimeas Asks, “Can VuLink Withstand Winter in Finland?”
Overview A months-long deployment reveals how VuLink telemetry performs in extreme cold. Challenge Winter temperatures in northern Finland can regularly drop below -20 °C or -4 °F, which can be hard on water monitoring equipment deployed for extended periods. In search of a telemetry device that could withstand such a frigid environment, Finnish equipment distributor Profimeas decided ...

Assessing protozoan risks for surface drinking water supplies in Nova Scotia, Canada
Protozoa, such as Cryptosporidium parvum and Giardia lamblia, pose a human health risk when present in drinking water. To minimize health risks, the Nova Scotia Treatment Standards for surface water and groundwater under the direct influence of surface water require a 3-log reduction for Giardia cysts and Cryptosporidium oocysts. This study determined the protozoan risk of municipal surface ...

Analysis of trace metals in drinking water with the optima 7000 DV ICP-OES
With the development of mining, smelting and other industrial activities, heavy metals are increasingly being found in freshwater sources which can pose severe threats to human and environmental health. Pollution by heavy metals (such as Cd, Pb, etc.) not only affects the productivity of crops, but also the quality of the atmosphere as well as water bodies and threatens the health and life of ...

Identifying water quality monitoring stations in a water supply system
Despite good quality assurance and conformance to the standards at the treatment plants, water quality could vary considerably within the distribution network. As water flows through the pipe network, its quality undergoes various transformations due to many factors such as the properties of the finished water, pipe materials, water temperature, water age and low level of disinfectant ...

Where is water temperature monitoring most important?
It is essential to monitor for abnormalities in water temperature, as the water chemistry can be significantly affected by fluctuations. Whether you are monitoring domestic or commercial water supplies, the temperature should be regularly checked. We would recommend regular water testing for all water supplies and, in agriculture, for continued monitoring of natural water formations. Below are ...

ITOXcontrol safeguards intake Romanian drinking water - Case Study
The Romanian water supply company Apavital has installed a monitoring station to safeguard the intake of water from the river Prut. The monitoring station is part of an integrated monitoring that signals sudden changes in the water quality of the rivers, enabling Apavital to take appropriate measures, in the worst case a stop of the intake. The iTOXcontrol is developed by the Dutch company ...

Ethanol Production Plant Monitors Impacts to Water Supply and Stays in Compliance
Application Under current ethanol plant configurations, water use for ethanol production ranges from 4.0 to 6.8 gallons of water required per gallon of ethanol produced. With the average new plant producing 120 million gallons of ethanol per year, water yields in excess of 1,000 gallons per minute are required; therefore adequate water supply is essential to the operation of an ethanol production ...

Topological clustering as a tool for planning water quality monitoring in water distribution networks
Topological clustering was explored as a tool for water supply utilities in preparation of monitoring and contamination contingency plans. A complex water distribution network model of Copenhagen, Denmark, was simplified by topological clustering into recognizable water movement patterns to: (1) identify steady clusters for a part of the network where an actual contamination has occurred; (2) ...

Performance of a permeable reactive barrier for
in situ removal of ammonium in groundwaterNitrogen as ammonium (NH4+-N) is one of the most common nitrogen contaminants in groundwater; this is particularly true in the industrial and agricultural regions of northern China, where rapid population growth and economic development have stressed public water supplies and reduced groundwater quality. In this study, we report the performance of a zeolite permeable reactive barrier ...

Proficiency test of non-target screening with gas chromatography mass spectrometry to confirm a detected contamination of raw and drinking water
Much of the water supply industry has implemented online monitoring and warning systems for chemical or biological contaminations. When a contamination is detected, further investigations are necessary to confirm or to cancel the initial alarm. The proficiency of a non-target screening approach with solid phase extraction and GCMS in full-scan mode was examined. A selection of pesticides and ...

Solutions for removing arsenic from drinking water
Arsenic, a metalloid element, is found in many naturally occurring compounds. In its inorganic form, arsenic is toxic. Arsenic occurs naturally in some groundwater supplies worldwide, including in the drinking water supplies in parts of Taiwan, Japan, Bangladesh, and western South America. This is causing health problems, according to the American Cancer Society. Albuquerque, New Mexico, is the ...
