2 The LiquID Station The LiquID Station is an intelligent optical, online instrument for multi-parameter water quality monitoring, with proven applications in water treatment, wastewater treatment, and other industries. The system features a fully automated design and low maintenance requirements and measures parameters related to organics, algae, common pollutants, solids and more. Through a series of engineering innovations, the instrument provides a unique combination of broad detection capability, robustness, accuracy, and reliability, representing the new generation of water monitoring instruments. The Optical Advantage Automated Water Quality Monitoring Operators commonly complain that current automated online water-quality monitoring equipment is demanding to operate. Some instruments use complex designs to perform automated wet chemistry analysis in a cabinet. Even without operator input for regular tasks, these instruments require trained technicians and operators to fill reagents, perform calibrations, empty waste vessels and carry out other maintenance. The LiquID Station features a number of technological innovations to alleviate the burdens of old technology by enhancing monitoring and detection capabilities. The instrument is a mechanically simple, solid-state device that uses light to analyze water quality and was engineered with a philosophy emphasizing reliability and ease of ownership. LiquID uses no reagents, has no waste stream, and has few moving parts. The system has true selfcleaning and self-calibration cycles that function automatically without any operator intervention, making operation truly independent.

3 Hyperspectral Detection Multi-Parameter Monitoring -parameter optical monitoring is its hyperspectral detection capability. The single optical platform in LiquID uses a broad-spectrum light, a broad-spectrum photon detector, and optical filters to monitor a select series light frequencies in rapid succession. These light frequencies range from the deep ultraviolet through the visible band and into the infrared. They are selected to represent the major constituent groups within the complex water matrix and are configured in each instrument to the parameter requirements of each specific user application. Hybrid Spectrometry Unmatched Detection which allows the system to monitor absorbance, fluorescence and reflectance all from the same optical platform. LiquID uses all three of these independent detection methods to measure water quality in real time. This is made possible through Zero Angle Photo- prietary design. More compounds can be seen using a combination of detection methods than using a single method. Thus, the multiple optical methods in hybrid spectrometry afforded by ZAPS provide increased breadth of detection capability.

4 Algorithmic Detection Reliability in Complex Matrices The LiquID Station collects reams of water quality data cycling through multiple different frequencies and using different detection methods with hundreds of repetitions in each measurement and stores it in an onboard computer database. Software algorithms in the computer process the data to break-down the complexity of the water matrix. This allows LiquID to apply matrix correction, whereby readings for the compound in question, such as total organic carbon in a turbid water stream, are separated from background noise. The formulae in the algorithms also allow for correction of distortions caused by quirks in the physics of optical detection, such as the nonlinearities caused by Flow Cell Design BOD in Real Time LiquID utilizes a revolutionary new method for real -time measurement of key oxygen demand metrics including Biological Oxygen Demand (BOD), carbonaceous BOD (cbod) and Chemical Oxygen Demand (COD). The instrument collects light measurements at many frequencies using multiple optical methods to characterize the complex water matrix at the sub-molecular level by looking at bonds of organic compounds. Onboard software algorithms process the data to create the remarkable ability to reliably measure oxygen demand in a continuous real-time basis for applications such as optimized process control and quality assurance in wastewater treatment. Maximum Optical Sensitivity At the heart of LiquID is its optical flow cell, where light from the instrument interacts with the online sample fluid stream. The proprietary flow cell design of the LiquID Station minimizes the number of interfaces in the light path, which increases the signal-to-noise ratio. Combined with a high-quality photon detector for collecting light readings, the result of this innovation is maximum sensitivity in an online optical instrument. Even small changes or small quantities are clearly detectible. Reliable Optical TOC Standard methods for total organic carbon (TOC) analysis using a lab bench-top or automated analyzer are generally labor intensive. Lab analysis requires a skilled technician, and automated systems are typically high-maintenance. ZAPS Technologies has developed a new method for real-time measurement of TOC. LiquID uses a proprietary high-energy frequency and broad detection capability combined with intelligent analytics to cut through matrix effects. The result is that LiquID is able to provide a robust TOC measurement with a detection limit of less than 20 parts per billion and boasts the reliability and ease of a reagent-free, automated optical instrument.

5 Ruggedized Hardware & Online Software The ruggedized LiquID standard design features a water resistant NEMA 4X enclosure and is rated to operate in a broad temperature range, so the system can be installed indoors or outdoors. Remote Monitoring LiquID also comes with ZAPSware online monitoring software. Measurement data is collected and stored in a database on the instrument. From there tem (such as a SCADA or PLC system) or transmitted via cellular modem to a remote online server, where it is accessible through a web-user interface to any authorized device (e.g. a computer or smartphone). The power of LiquID to reliably monitor multiple water-quality parameters in real time can be installed anywhere there is access to power, a cellular signal, and a water stream to sample. -

6 Extensible Platform For Multiple Applications With multi-parameter capability from a single platform, LiquID is extensible to a wide range of applications, and has been installed and tested in various settings: Drinking Water Treatment and Water Security For water treatment facilities, LiquID is used for monitoring source water, both directly at the influent point and remotely further upstream. With sensitivity to a wide range of constituents, the instrument acts as a powerful event detection system by alerting operators and providing characterization of key changes in water quality. Events such as algal blooms or contamination from sewage leaks, agricultural runoff, and chemical spills are clearly identifiable with -time multi-parameter monitoring. LiquID event detection capability provides a capable sentinel to ensure the security and integrity of both source waters and finished water in distribution. LiquID provides direct return on investment benefits by reducing labor costs of manual testing, reducing the number of required instruments to purchase and maintain, and providing a wealth of information for process optimization. Wastewater Treatment There are two key applications for the LiquID Station inside a wastewater treatment facility. The first is monitoring effluent. LiquID continuously monitors for a number of parameters found on a typical NPDES permit and provides reliable, automated high-frequency testing with minimal operational input requirements. The second application is in the secondary treatment process. For plants with advanced process control systems, real-time LiquID provides the data necessary for biological process optimization, promoting energy efficiency and biosolids reduction. Industrial Process Control and Verification The -parameter detection and matrix correction capability is a boon to industrial process managers and engineers. Algorithmic correction allows the instrument to reliably function in challenging process streams such as waters that are turbid, high in organics, brackish or saline. One example is the processing of raw agricultural products using a chlorine wash. Chlorine levels must be tightly controlled to ensure the safety of both finished product and workers in the plant, but dirt and organics in the wash mix confound typical chlorine measurement methods. The intelligent analytics in LiquID successfully monitor chlorine levels in wash waters that contain high levels of turbidity and biological material. Specialty and Custom Applications LiquID has the capacity to monitor multiple parameters in varied fluid streams and the extensibility to be configured for new parameters. With those features, LiquID is adaptable for new applications where attempts with other instruments have failed. The science and engineering teams at ZAPS Technologies have extensive experience with parameter development and analysis, and are available to assist in creating monitoring capability for high value applications on a custom basis.

LiquID is a versatile platform and can be installed in a wide range of applications and excels where real-time information is valuable and broad contaminant detection capability is critical. The technology and design of LiquID originated from the invention of ZAPS Chief Science Officer Dr. Gary Klinkhammer, who has over 25 years experience in the fields of environmental monitoring and spectrometry. Dr. Klinkhammer wanted to study oceanographic conditions using a sampling device mounted on a trailer dragged by a US Navy nuclear submarine. He required automated, robust instrumentation with multi-parameter capability for this application. Unable to find satisfactory equipment, he set out to create his own and developed an innovative, novel optical platform. The current LiquID Station is the third generation of evolution from his original invention.
