Hydromantis Announces a Partnership with WEF's Operations Challenge

Hydromantis is very pleased to announce our new partnership with the Water Environment Federation (WEF) to add process simulation into the annual Operations Challenge event at WEFTEC.

Starting in 2016, teams will use a Hydromantis’ SimuWorks™ simulators to troubleshoot treatment process problems as part of the Process Control event. Operators will be presented with simulations of treatment systems that are not achieving desired objectives, and will make operational changes to improve effluent quality. Several challenges will be available, and include bonuses for achieving excellence in operation such as lowest operating cost.

Hydromantis is demonstrating the Operator Challenge simulators in their booth (#1656) at WEFTEC.2015.

Drop by and take a spin on the simulator or sign up to receive updates on the new simulation event at the WEFTEC Operations Challenge.

Collaboration with the University of Lisbon on the development of a metabolic biological nutrient removal(BNR) model

Hydromantis is collaborating with the Departamento de Química at REQUIMTE/CQFB in the Faculdade de Ciências e Tecnologia at the Universidade Nova de Lisboa (Departamento de Química at FCT-UNL) to jointly develop a metabolic biological nutrient removal (BNR) activated sludge model in GPS-X, which can be used to simulate biological nutrient removal activated sludge wastewater treatment processes.  As part of the collaboration, Departamento de Química at REQUIMTE/CQFB, FCT-UNL will assist in teaching a future workshop on metabolic models for GPS-X users.


CIRAIG Life Cycle Assessment Project (LCI) Database Project

Hydromantis is collaborating with a group of researchers working on life cycle analyses (LCA) at the CIRAIG École Polytechnique de Montréal on the development of life cycle inventory (LCI) datasets for wastewater treatment. The CIRAIG LCI team is using GPS-X, CapdetWorks, and Toxchem to assist in developing local (LCI) data to properly assess the impacts of water-related activities. The resulting datasets will be integrated in the Quebec LCI database (and hence be used in most Quebec carbon footprinting projects) and in the global ecoinvent database (and hence be used in a large proportion of LCA analyses worldwide). The work will be summarized in two scientific papers, one for the LCA community and one for the water and wastewater treatment community.

NSERC Engage Project with Ryerson University:  Optimal Selection of Treatment Trains using CapdetWorks

Hydromantis and researchers at Ryerson University just completed a project that resulted in the development of a genetic algorithm-based optimizer for use in CapdetWorks for the selection of optimal treatment trains in terms of capital and operating costs. The genetic algorithm may also be incorporated into GPS-X for the optimization of treatment performance and for parameter estimation.

WEF Forum

Oliver Schraa, Hydromantis President, attended the WEF Forum: “Activated Sludge on its 100th Birthday: Challenges and Opportunities” on June 9-11, 2013 at Stonehill College in Easton, Massachusetts.

This forum brought together the sector's prominent professionals and academics to reflect upon the state and future of activated sludge. The Forum followed the Gordon Conference format that fosters rich discussion and close interaction between attendees. The Activated Sludge process was developed less than 60 miles away at the Lawrence Experimental Station in Massachusetts.

Hydromantis and OCWA to Offer Advanced Water and Wastewater Treatment Plant Simulation Technologies

HAMILTON, February 14, 2013– Hydromantis Environmental Software Solutions, Inc. (Hydromantis) and the Ontario Clean Water Agency (OCWA) announced today that they have entered into a Memorandum of Understanding (“MOU”) to enhance water and wastewater treatment plant operations and operator training through the advancement of leading-edge simulation based technologies and services. 

Based on Hydromantis flagship products, GPS-X™ and SimuWorks™, Hydromantis and OCWA are creating opportunities for real-time simulator integration with supervisory control and data acquisition systems (SCADA) for decision making support and leading-edge water treatment simulators.

“OCWA is the largest operator of water and wastewater facilities in the province and our promotion of leading edge technology is fundamental to our drive for operational excellence,” said OCWA President and CEO Jane Pagel.  “Hydromantis simulation technology is already presenting our staff with an unparalleled operator training environment and the implementation of real-time links between GPS-X™ and operator control systems will provide forward looking, actionable data for improved decision making support,” she added.

“Hydromantis was the first company in the world to commercialize wastewater treatment plant simulation technology and we are unique in our ability to combine specialized wastewater treatment consulting and advanced simulation technology,” said Robert Beres, Hydromantis Chair and Managing Director. “Both OCWA and Hydromantis are well known as innovators in the water and wastewater industry and this partnership makes perfect sense as we look to introduce auto-calibration and continuous simulation engines into treatment plant information systems.”

About OCWA
The Ontario Clean Water Agency (OCWA) provides environmentally responsible and cost-effective water and wastewater services to municipalities, institutions, industry and First Nations. Established as a provincial crown agency in 1993, OCWA operations, engineering, and technical services provide clean water expertise to communities and businesses all across Ontario. www.ocwa.com
