ColiMinder™ provides fully automated, rapid microbiological contamination measurements within 15 minutes. ColiMinder™ rapid microbiological on-line measurements enable process monitoring and control for all water related applications.

Microbiological contamination measurement in real-time enables a drastic increase in efficiency and safety of water treatment processes and distribution networks. ColiMinder’s reliability and robustness have been proven since early 2014 in different applications from drinking water through surface & bathing water to waste water and industrial water at customer installations all around the globe.

The technology is based on direct measurement of specific metabolic (enzymatic) activity of target organisms.

The Subnero Water Assessment Network (SWAN) comprises one or more low-cost, robotic swans that can navigate autonomously, collect water samples at different locations, analyse them in the field and upload the results to a central server, where the user can monitor it from the comfort of his/her own office. A bevy of SWANS can do simultaneous temporal and spatial data sampling in a cooperative and adaptive fashion making them perfect for obtaining statistical coverage. They need minimal logistical support as they return home automatically after their tasks are completed.

Accurate and reliable data from the field is the necessary starting point in delivering the information required to enable managers and operators of complex infrastructures, systems, and smart services need to think quickly, act prudently, and plan strategically.

Ayyeka’s end-to-end technology solutions provide accurate and reliable data from the field.

Connecting decision makers’ desktops directly to dispersed and remote assets enables effective and sustainable management of infrastructure and systems of every kind. Monitoring is easier, choices are more informed, transparency increases, and productivity grows. Ayyeka’s scalable platform is an advanced, economical alternative to expensive legacy data capture and time-consuming manual data collection. Ayyeka’s solution consists of the Wavelet edge device that connects to one or more sensors and generates data, and the StreamView data hub (a data and device management

software IoT platform).

The presence of algae in surface waters is a potential threat to the quality and ecology of the water system. Therefore, the monitoring and control  of the algae types and concentrations is very important.

The ALGcontrol offers online monitoring of different algae types by continuously measuring the chlorophyll fluorescence of different algae classes in real time. Compared to time-consuming sample preparations and counting by microscope, the on-line fluorescence monitoring provides quick determination of the chlorophyll content in for example lakes, rivers and reservoirs.

The ALGcontrol makes use of fluorescence excitation. This means that when chlorophyll molecules absorb light, a fraction of the energy absorbed is re-emitted as fluorescence. Due to the fact that algae of the same class contains a similar quantity and quality of pigments, their fluorescence excitation spectrum (with a fixed emission wavelength at 680nm) is significant. Thus, it is possible to differentiate classes of algae by their fluorescence excitation spectrum.

Traditional chemical analysis, alone, is not enough to get a complete view of water quality.  Biomonitoring of behavioral responses and stress levels, experienced by living organisms, is important as it can be used for assessing toxicity as a first line of defence in managing the use of source waters.

The most important drivers for on-line biomonitoring systems are:

1. Traditional analyses are only possible for a small number of the dangerous chemical substances, even with the latest highly sophisticated instruments.
2. It is estimated that only about 5% of the existing toxic chemicals in water can be analysed by on-line monitors.
3. Concentrations of many products are lower then the detection limits.
4. Results of traditional, chemical analyses give no information regarding the toxicity of the combined effects of mixtures

The iTOXcontrol uses a decrease in luminescence of the Vibrio Fischeri bacteria as an endpoint effect to measure the toxicity of water samples. The acute test with this bacteria species is one of the best known ecotoxicity tests and has been used in ecotoxicological research since the 1980’s.  It is internationally standardized and accredited (ISO 11348 Determination of the inhibition effect of water samples on the light emission of Vibrio fischeri).

The iTOXcontrol can be Integrated with different optional sensors like a UV-VIS sensor or Algae sensor (for Chlorophyll-a and blue-green algae) which creates a combined system for Early Warning and Water Quality Monitoring .

Optimos flow cell Optimos has designed and developed an atmospheric flow cell for use with a wide variety of water quality sensors.  The flow cell, which can be supplied in stainless steel or non-metallic forms, offers several benefits;

• Constant sample level
• Adjustable flow
• Grit and bubble removal
• Easy access to sensors for manual cleaning and calibration
• Can also be used as the sample reservoir for analyzers that incorporate a sample pump
• Can accommodate automatic sensor cleaning options, including compressed air and chemicals
• Easily washable
• Vermin proof construction
• Can be wall or floor mounted

Optimos designs, builds, installs and supports complete water quality monitoring solutions for the water, wastewater and food and beverage industries.  Endress & Hauser is our preferred supplier of high quality instrumentation for these solutions.
