Wastewater Monitoring Equipment for An Airport Group

CLEVELAND - Aug. 21, 2018 - PRLog -- CAS DataLoggers recently provided the wastewater monitoring solution for a major airport group based in the UK whose fluid run-off threatened to endanger the aquatic ecosystem near the airports. The commercial airline needed an online device capable of monitoring toxic discharges into local rivers. The airline routinely sprayed de-icer and anti-icer solution onto their aircraft before taking off during icy conditions as mandated by FAA guidelines. Between 100 and several thousand gallons of de-icing fluid was used per aircraft application. While a portion of the fluid stuck to the planes, approximately 75% to 80% of the treatment would flow into the surrounding environment as run-off.

The bases of all de-icing fluids contain propylene and ethylene glycol, also used as antifreeze in cars. While the deicers were decreasingly toxic, the anti-icer mixtures contained chemical additives preventing the formation of new ice. As government agencies were developing storm water run-off guidelines for the airport de-icing procedures, this group of airports were going to great lengths to monitor their toxic run-off to accommodate future regulations and lessen the environmental impact.

Installation
CAS DataLoggers Applications Analysts determined a DT82EM (https://www.dataloggerinc.com/product/dt82em-environmenta...) 3G modem equipped data logger connected to an ultrasonic flow meter, would immediately provide the airports remote online web access to both current and historical data on discharge and flow volume. The DT82EM system featured analog, digital and serial sensor interfaces, local data storage, smart power management, batteries, a solar regulator, a 3G modem, and a global SIM card—all incorporated into a single unit. The data recorder also intelligently controlled and powered the airport sensors which supported a wide range of interfaces and protocols. Data was transmitted from onsite to the data logger manufacturer's central servers via the integrated 3G modem. The wastewater monitoring system was interfaced with Flo-Dar flow sensors (https://www.hachflow.com/flow-sensors/flo-dar.cfm) for real-time data collection. The Flo-Dar sensors combined digital doppler radar velocity sensing technology with ultrasonic pulse echo level sensing to remotely measure open channel flows.

Ruggedly-designed, the dataTaker was housed in an IP65 weather-resistant enclosure, guaranteeing extreme durability. It had ultra-low power requirements, and the unit was further supplemented by solar power.

Usage
The dataTaker's many added capabilities helped staff to monitor the waste water run-off more efficiently. For ease of use, airport staff could remotely configure the logger from the hosted website, viewing both live and historic sensor data. The DT82EM's internal webserver offered powerful and intuitive website graphing features, moving graphs back and forward in time and zooming in and out. This allowed users to overlay multiple sensors, view statistics and work with the data more flexibly.

Benefits
The customer instantly benefitted from the installation of the DT82EM wastewater monitoring system in several key ways. The data logger eliminated the complexity and cost of manually collecting and organizing the data from the airports' remote field-based sensors, instruments and control systems. This complete solution was rapidly installed and implemented. Easy operation by personnel without relying on IT infrastructure became apparent as well. The advanced graphing and mapping features allowed the airport group to more easily and efficiently monitor the run-off from each of the airports in the client's group. Alarm conditions and recipients were maintained from central website and personnel could distribute alarms via email, SMS text message, or web service calls. Each device alarm could be independently enabled or disabled, and all alarms were stored locally as well as logged onto the central servers.
