SIMPLE USER INTERFACE

The custom-made user interface of Design Generator enables users ranging from those with minimal wastewater engineering knowledge to those with significant expertise to generate and analyze complete preliminary wastewater treatment facility designs. Starting with the entry of a number of simple input parameters, engineering decisions take place in a completely automated fashion. To guide users throughout the data entry process, special data validation parameters are present to ensure data quality and consistency.

The data validation is based on general process design principles used in all biological wastewater treatment processes, independent of size, location or technology. Special, non-required fields are also implemented, to give wastewater experts the option to incorporate more specific, customized input parameters, resulting in designs which more closely match specific client requirements for any situation.

PROCESS DESIGN SIMULATION

Using the data inputted by the user, supplemented by additional details from our proprietary influent, effluent, and regional databases, Design Generator starts with a full wastewater treatment process simulation. Through the representation of chemical, physical, biological, and other technical processes and unit operations, all run in industry-standard simulators, highly defined Process Simulations are executed within Design Generator.

The outputs of the simulation serve as a basis for all Process Schemes and Process related documentation generated by Design Generator, as well as provide input for equipment selection and BIM model generation. The simulation uses both Steady-State and Dynamic modeling, capable of introducing variable parameters, such as influent wastewater temperature fluctuations or daily and seasonal influent flow variations. Design Generator is capable of creating engineering documents for CAS, MBR, IFAS, MBBR, and other facilities. In addition, due to the modular nature of this subsystem, alternative technologies can be implemented with ease.

EQUIPMENT SELECTION

Once the process simulation is complete, Design Generator uses a combination of the input data, simulation outputs (tank sizes and process unit selections), and decision algorithms in order to size and select each piece of equipment needed to construct the wastewater facility. Design Generator leverages an extensive equipment database built up over a decade, containing up to date size, power, and other relevant data on every equipment type.

We work closely with equipment suppliers including screening, blower, diffuser, belt press, pump, valve, and other mechanical equipment manufacturers in order to ensure accuracy and consistency in the equipment selected. Once the mechanical equipment has been sized and chosen for the project, Design Generator chooses the valves and instruments, then generates a virtual Equipment List and Instrument List, which is later used by the Drawing Generator Module to create the P&ID and other documentation needed for the project.

ABSTRACT BUILDING MODELING

After all elements of a wastewater treatment facility are selected and designed, the next step is determining how the facility will be structured. Depending on both Mechanical Engineering and Process Modeling outputs, Abstract Building Modeling solves the challenge of placing all elements of a wastewater facility in physical space. Designing reactor spaces, equipment buildings, and control room location are all part of this coordination management process, along with the finer details of architecture such as wall thicknesses, construction materials and general building construction elements. To create as sophisticated of a model as possible, the subsystem utilizes optimized generative algorithms for general architectural arrangements. The whole process serves as a tool to finalize all documentation and specifications in a very time efficient and platform independent manner.

BUILDING INFORMATION MODEL (BIM)

After all steps of designing the facility are completed, the outputs are introduced into a CAD-based system capable of modeling and visualizing every element from the Mechanical Equipment selection and Abstract Building Modeling subsystem. In this environment, not only are 3D models generated, but whole databases are automatically and simultaneously created representing and describing the wastewater facility with pinpoint accuracy. These databases store all engineering requirements, details, and properties in one central model, enabling Design Generator to introduce a final validation and filtering protocol, eliminating all errors and inconsistencies in the finished design and document outputs, and keeping qualities at the highest levels. All civil documentation, such as Floor plans, Sections, Layouts, Site Plans, Elevations, and Civil Bill of Quantity documents are automatically generated from this central model, while keeping all related annotations and remarks in a template that can be further customized for detailed engineering work as the project progresses.

DRAWING GENERATOR MODULE

The various output packages of our Process Design Simulation, Equipment Selection, and BIM are communicated directly to Design Generator’s Drawing Generator module. In return, Drawing Generator handles the complete process of drawing generation for all engineering documents, including Process Schemes and Piping and Instrumentation Diagrams. This module working by dynamically generating the drawings from thousands of mini-drawings, assembling the components like a puzzle to match the final design decisions made in the earlier stages.

Depending on the Process Design Simulation and Equipment Selection outputs, these documents are labelled with proper item quantities and equipment specifications, resulting in very precise, accurate P&ID and Process Schemes for that given project. As a final step, all details from these document packages are collected in one database and an Equipment List, Instrument List, Load List (for precise electricity consumption), and Operation Cost estimation document are all generated. With this data the user can easily estimate both the Capital and Operating cost of the facility, allowing the user to make the best decision for a given project.
