drinking water testing Applications

  • Drinking water testing

    Water is essential for life. It is part of the environment, being used in industrial processes and available as tap water. To secure the safety of water that is daily available, the amount of necessary microbiology tests to comply with regulatory requirements are increasing and are heavily relying on quick and accurate answers to confirm the identities of a broad selection of important micro-organisms.

  • Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

  • Drinking water solutions for the source water monitoring/ protection

    Problem: A challenging aspect of drinking water treatment is often predicting or monitoring the changes that occur with incoming water quality. Seasonality, weather events, agricultural practices or upstream discharges can influence the quality of both ground and surface water over time. With multiple variables impacting source waters, monitoring historical trends may not be sufficient to predict raw water changes or detect uncharacteristic events.

  • Algae monitoring of drinking water reservoir -

    Due to green algae problems in the water reservoir of a drinking water treatment plant, the ALGcontrol was installed to continuously monitor the algae concentrations and possible toxic blue green algae blooms. During almost 4 months the ALGcontrol measured the total chlorophyll and cyano chlorophyll concentrations of the water reservoir. In order to be able to compare these results, second off-line controls were carried out using the ISO 10260 chlorophyll-a quantification (extraction into ethanol, spectrophotometric detection at 665 and 750 nm). The results of the off-line standard lab method show a good correlation with the measurements of the ALGcontrol. The good correlation can be verified as well at high as at low concentrations of total chlorophyll.

    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important process for a wide variety of applications including: medical, laboratory, desalination, industrial wastewater, Deionized (Dl) pretreatment, and drinking water.

  • Water Monitoring and Flow Measurement Systems for Water Supply

    Although there is enough water on earth, its uneven distribution, the rising population and our carelessness drinking water starts to get short. In the future more and more pipelines for drinking water will be built all over the globe. In order to operate huge and complex pipe networks efficiently, water flow measurement and flow monitoring will become necessary. The increasing efficiency of ultrasonic flow meters will make such calculations more and more effective.

  • Water Monitoring and Flow Measurement Systems for Hydrology

    In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants. A further important use of transit-time open channel flow meters is the transportation of water used for the supply of drinking water. Here the focus lies on detecting the flow rate of water loss at an early stage as it is sometimes difficult to detect small leakages.

  • Dust monitoring and Sand Storm Monitoring

    The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.
