Demonstration cellulose recovery from sewage in Italy

Gruppo CAP and CirTec B.V. signed an agreement for the rental of a Cellvation installation at demo-scale for a period of 5 months. Gruppo CAP is the first Italian water authority to recover cellulose from sewage. The installation will be installed at STP Truccazzano starting November 2020. All Recell® (cellulose recovered by Cellvation) will be supplied to the local industry and used as a raw material. For CirTec B.V. and Cellvation B.V. an important step outside the Netherlands for the international marketing of the technology.

10 years anniversary of CirTec

10 years anniversary of CirTec

A special day today, we are celebrating our 10th anniversary. On July 8, 2010, CirTec, at that time BWA, was founded. I look back with pride on the history of our company. What started as a company with two people has grown into a reliable market player with more than 100 references. A great opportunity to thank all employees, customers, suppliers and stakeholders who made this possible, for their enthusiasm, support and dedication.

CirTec got off to a flying start with a first assignment for finesceens at a tannery and other assignments from the industry for other separation techniques such as polishing filtration and tilted plate settling. In the municipal market, the first years mainly consisted of research, in which we collaborated with almost all stakeholder involved in the sector. Initiated from a project of the joint water authorities under the name “De Energiefabriek”, fine sieves were used to relieve the downstream biological treatment (physical removal of load) with the aim of limiting energy consumption. With the realization of fine sieve installations on eg. Ulrum (CADoS), Beemster (Cellu2PLA) and Aarle-Rixtel (ScreenCap) a lot of experience was gained in the design and realization of fine sieve projects. An area where CirTec is an absolute frontrunner.

However, with the research into the application of the sieving technology, a new stream was released on the STP, which appears to consist mainly of cellulose that comes from the toilet paper that we flush. By utilizing cellulose from sewage water as a high-quality raw material, the CO2 footprint of a treatment plant is reduced with > 2 tons of CO2-eq / ton of cellulose. After the installation we have built within the SMART-Plant project on the WWTP Geestmerambacht, we are now also working on the recovery of cellulose outside our national borders.

In addition to a wide range of sieving techniques, the CirTec portfolio also includes equipment for sludge thickening, dewatering and drying from Giotto Water, as well as evaporators and strippers. In every step from water purification process, pre-treatment, main purification, post-treatment, we can support customers and select the suitable technology.

We are happy that our customers rely on our expertise to help them solve their (waste) water issues. Their demands, challenges and feedback have prompted us to continue and improve. In addition to our customers, partners and suppliers have been equally important. All of them have made an important contribution to knowledge development and have enabled us to put a reliable product on the market.

Looking back in ten years’ time, I hope that the useful reuse of raw materials from wastewater has become the norm across Europe. With partners in the WOW! and CellCap, we are working hard on this, as are other parties in the water sector. It has been ten exciting years and we have a great time!

From linear to circular sewage treatment with SMART

From linear to circular sewage treatment facilities with SMART

In the SMART plant project a couple of technologies have been researched for the recovery and reuse of resources from sewage. The linear sewage treatment produces a clean water source, but at the cost of the potential to recover a lot of valuable resources. During this type of treatment the foulants are converted into greenhouse gasses and sludge. The treatment process is a very energy consuming process.
The technologies researched within SMART are focussed on the recovery of recourses and the useful application of these recovered materials. The SMART plant project makes the step to a circular treatment, in which the recovery and reuse of resources and water is central, easier. The SMART plant project has ended and the deliverables containing the findings of SMART plant are placed on the SMART plant website: https://www.smart-plant.eu
