Water Monitoring Company Continues to Expand Product Line with Take-Over of Austrian Company
microLAN (Netherlands) took over Austrian company mbOnline, specialists in monitoring bacterial water pollution. mbOnline supplies the Coliguard early warning monitor for the automatic measuring of micro-organisms. By taking over mbOnline, microLAN can add the Coliguard to its existing product line that includes the early warning iTOXcontrol and ALGcontrol monitors. The acquisition of mbOnline enables microLAN to offer a full range of fully automated online monitoring devices for guarding the quality of drinking and surface water. microLAN now supplies three complementary systems that detect Algae, Bacteria and Chemical pollutions.
microLAN’s online monitors instantly response to a change in water quality, giving an alarm signal to indicate a possible water pollution. The devices are in use by water utilities and industries that take in surface water and want to monitor the water quality.
Acoustic Leak Detection The HL50 Leak Locator
The advantage of microLAN’s monitoring is that the water intake is guarded permanently, avoiding the need for a high frequent
collection of water samples and lab analyses. A possible pollution is detected within minutes, allowing the operator to take appropriate action immediately.
The Coliguard has been developed by mbOnline and is now added to the product line of microLAN (and will be named BACTcontrol). The Coliguard detects the presence of bacteria - including
E.Coli and coliforms - in water. The online monitoring is based on an Enzymatic reaction that makes the bacteria visible for fl uorescence detection. By adding the Coliguard monitor, monitoring systems are now also of interest to the food industry and in case of the reuse of treated waste water.
The ALGcontrol has been developed by microLAN and is part of the product range since 2013. The ALGcontrol detects the presence of algae in surface water. It can identify classes of algae and convert fl uorescent values into chlorophyll-a concentrations and blue-green algae (or cyanobacteria) concentrations. The ALGcontrol can also be included into the iTOXcontrol as a separate option making it a unique combination to monitor in one system for algae and chemical pollution.
The iTOXcontrol is microLAN’s fi rst online (bio)monitoring system, introduced in 2006. iTOXcontrol detects the acute chemical toxicity of drinking and surface water caused by organic chemicals and heavy metals. It functions by exposing the luminescent Vibrio fi scheri bacteria to intake water. These bacteria generating reduced light in the presence of increased toxicity.
Rapid Bacterial Analysis - Giving Water Quality the Green Light

Baseline (USA), a MOCON company, offers a fast, cost-effective way to perform bacterial analysis on water. In as little as 45 minutes, the GreenLight calculates total bacteria load in any water supply. Not only is the instrument fast, it is also compact and easy to operate.

Little thing, big difference
GreenLight is perfect for environmental applications such as water quality, wastewater treatment, industrial wastewater, environmental water quality and beach monitoring as well any other water based application where rapid results are needed.
The Must-Have for quick leak surveys, leak pinpointing and indoor leak detection.
Lightweight, precise, absolutely easyGO.
Measuring dissolved oxygen using fl uorescence chemistry, the GreenLight’s principal of operation is based on respiration of aerobic bacteria. The device measures the amount of oxygen, which then determines the levels of live active bacteria.

The Optiqua (Netherlands) EventLab offers a real-time contamination detection system for for monitoring of water quality in drinking water distribution networks. The major components of the Optiqua EventLab system are an online optical sensor, data transmission infrastructure and software for data analysis and event detection. EventLab measures minute refractive index changes in water, which are a generic indicator of water quality because any substance, when dissolved in water, will change the refractive index of the water matrix. EventLab allows monitoring of the water quality for any change in (chemical) composition with the use of a single sensor, without the use of chemicals or other
consumables.The EventLab sensors are connected to Optiqua’s event detection software (EventLab Online), a web-based application, that handles event detection and which enables water companies to keep tabs on the water quality throughout theirentire network, in real time. The combination of a low cost, low maintenance, robust optical sensor with a scalable central data processing software, means that EventLab is especially suited for deployment in high density networks.
EventLab has been adopted by a number of leading water utilities, including Vitens (the Netherlands) and PUB (Singapore). With these networks of EventLab sensors water quality incidents have been detected and tracked, which were not picked up by the traditional online monitors in place. Optiqua has teamed up with 20 partners in the Vitens led EC FP7 SmartWater4Europe project, to demonstrate smart water management solutions.
