SimuWorks - OPERATOR SIMULATOR FOR ADVANCED TRAINING AND PLANT ANALYSIS SimuWorks is an industry first - a flight-simulator for water and wastewater treatment plants. Utilizing customized operator interfaces, SimuWorks presents views and functionality familiar to operators and administrators alike in a platform that accurately simulates the behaviour of a specific plant. There are different incarnations of the SimuWorks platform depending on an organization’s requirements – OpToolPro is the out-of-the-box version or customized version to represent a specific plant. OpTool Pro - Out-of-the-box version of SimuWorks. A tool to allow operators to explore the causal relationships between operational settings and the effect on performance of an activated sludge treatment facility. OpTool Pro is a generic virtual activated sludge treatment wastewater facility using a calibrated plant model as an underlying computational engine. The facility includes preliminary treatment systems, primary clarification, a two-train activated sludge process, secondary clarifiers, thickener and sludge disposal. The platform features both training and testing modes. Standard - This platform provides a direct replication of a bird's eye view of your actual water or wastewater treatment facility. The graphical interface and output schemes is similar to OpTool Pro. Key operations at the facility are dutifully captured. The development of the simulator is based on steady state calibration using average values of key parameters. (CAS) - Applicable to conventional activated sludge systems using any technology (e.g. ASP, SBR, Oxidation ditch etc.). (Media) - Applicable to systems that also include fixed film media based processes (e.g. MBBR, IFAS, etc.). All solids handling facilities and liquid recycles in the plant are included in the system development. Advanced - The graphical interface and output schemes is customized based on your requirement (bird's eye view, SCADA look-and-feel or other graphics). Applicable to systems that can include fixed film media based processes (e.g., MBBR, IFAS, etc.), this platform dutifully captures key operations at your facility. The simulator includes scenarios specified by you, and provides you with the ability to develop additional scenarios. Steady - The development of the simulator is based on a calibration done using average values of key parameters. Dynamic - The development of the simulator is based on a calibration done using dynamic values of key parameters. Benefits of a Site Specific Calibrated Model These site specific calibrated models, deployed within customized operator interfaces or dashboards, offer: Advanced operator training and education Rapid identification and validation of plant optimization and cost-saving strategies Sophisticated project and operational risk analysis Key decision-making support for all levels of management SimuWorks can be deployed as a complete life-size replica of a specific control room, set-up as a mobile control room for regional training with a library of various plant models, used in more traditional multi-station classroom environments or loaded on individual workstations. Advanced Operator Training and Development SimuWorks TM is a state of the art operator training and development platform that allows instructors to train and evaluate new or existing operators in a controlled and safe environment. The training can offer actual SCADA or customized look interfaces tied to the plant models that closely simulate actual plant behaviour. The training offers exposure to many simple or highly complex scenarios within a realistic environment but with no risk to actual plant performance. Since the trainees can operate the virtual plant in the same manner they would the real plant (e.g. have access to the same operational control parameters, such as DO set-points and sludge wastage), learning is systematic and adopted well. Site-specific models have been used to train operators on such topics as step- feeding during storm events, troubleshooting nitrification/denitrification and what to do during periods of poor settling. Plant and Process Optimization SimuWorks offers a platform for fast and efficient testing and validation of any number of plant optimization or upgrade possibilities without putting the plant at risk. Operators, engineers, management or any other user type can evaluate new technologies, test new operational control strategies, run “what-if” scenarios (capacity, flow rates, chemical dosing, energy usage, etc.) and more. The implementation of SimuWorks can promote a better understanding of plant control at all levels within an organization. Project Management and Risk Analysis SimuWorks becomes an important part of the planning process for projects. By simulating various scenarios around downtime for plant maintenance or modifications, potential risks can be identified and optimum project planning achieved. TOXCHEM - PREDICT AND REPORT TOXIC EMISSIONS The tool allows users to build a plant, select contaminants and observe emissions. Toxchem is mainly used for estimating VOC air emissions from wastewater collection, preliminary/primary/secondary treatment and disposal facilities. The site specific wastewater characteristics, contaminant properties and the process design and operating information are used to estimate VOC emission rates. In addition to air emission estimates, Toxchem can also be used to estimate the concentrations / loads of contaminants in the water effluent, or oil and residual solids streams. Toxchem is based on fundamental mass transfer equations and mass balances including the removal mechanism of stripping and volatilization, biodegradation and sorption. Thus, it can also be used to determine the fate of any synthetic chemical compounds for which the physical, chemical and biodegrading properties are known. Typical applications could be in assessing the fate of chemicals for the REACH legislations in EU or studying the fate of Endocrine Disrupting Compounds in wastewater treatment plants.

Toxchem includes an extensive database of semi-volatile and volatile organic compounds (VOC) and their relevant properties for stripping, sorption, biodegradation, etc. The database also includes a suite of metals so that the fate of a number of metals, including mercury and silver, can be followed through both liquid and solids handling processes. Applications can include tracking metals from influent wastewater through clarifier underflows, dewatering and drying processes, and incineration. If a desired VOC isn't present or you wish to experiment how different properties affect the emission rates, you are able to create your own organic chemical compounds and modify the properties accordingly.
