Challenge Detected

University of Zagreb, Faculty of Civil Engineering, Department of Hydroscience and Engineering has been working on several projects regarding water and wastewater treatment. Their focus is on developing electrochemical and ultrasonic technologies for water disinfection with the efficiency of developed methods being evaluated by the presence of total coliforms and Escherichia coli (E.coli).

University of Zagreb, Faculty of Civil Engineering, Department of Hydroscience and Engineering has been working on several projects regarding water and wastewater treatment. Their focus is on developing electrochemical and ultrasonic technologies for water disinfection with the efficiency of developed methods being evaluated by the presence of total coliforms and Escherichia coli (E.coli).

As the process to evaluate these technologies was involved, the institution’s aim was to:
- reduce outsourcing services and costs for microbiological analysis,
- achieve research independence; and,
- receive rapid test results.

Solution Detected

The TECTA™ B4 unit is an out-of-the-box solution that could help to address all of the identified requirements and as a result they introduced the TECTA™ B4 to test for E. coli and Total Coliforms. The unit can provide on the spot test results in 2-18 hours, depending on the level of contamination, much faster than traditional methods – without the need for a lab or a microbiologist.

The TECTA™ B4 was developed by TECTA-PDS to provide accurate and fully automated testing for E. coli and Total Coliforms. The TECTA™ B4 automatically transmits the data through a network connection allowing for immediate notification on electronic devices such as cell phone or laptops as soon as a contamination event is detected.

Success Detected

The TECTA™ B4 unit enable the University to speed-up research by eliminating the need for time-consuming microbiological tests. In addition, due to the intuitive and simple design, they found it easy to use right out of the box without the need for any special training of personnel.

“Easy operation and rapid results helped us in process optimization,” said Dr. Ivan Halkijevic, Ph.D., Civ.Eng., who is an Associate Professor at the University. “With TECTA we are able to gain results in less than a day, in contrast to a several day process of collecting, preparing and transporting the samples to an outside lab.”

Another key feature of the B4 unit that aided the University in process optimization was the ability to test samples regardless of water quality. A unique feature of TECTA technologies is little need for sample preparation, enabling the ability to test coloured and turbid samples.

“TECTA-PDS is delighted to be able to aid the University of Zagreb in their ground-breaking research efforts to create technologies and solutions to enable safer water,” said Tim Adams EVP, TECTA-PDS. “As our technologies were also created through scientific efforts in a University setting, we understand their need for a reliable, speedy solution that helps them move forward in their process.”
