Large-scale production of Crescendo

Crescendo is an innovative evaporator for corrosive liquids and gasses. The synthetic GaLiCos evaporator is made of high quality synthetic material and has a modular design. We’re proud to announce that, after performing the last functional tests, the large-production of the modules has started at the site of our Dutch supplier.

Crescendo is a technology that can evaporate corrosive and highly concentrated waste streams, such as brines, to the saturation limit. It can be applied for waste streams coming from flue gas treatment, desulphurisation and corrosive liquids and gasses in a wide pH range from 1 to 14. Low value energy can be applied as energy source, since Crescendo can run at low temperatures. The development of Crescendo was subsidised by the Partners for Water 2016-2021 programme.

European Water Tech Week

Later this month the European Water Tech Week (September 24 – 27, 2018) takes place in the city of Leeuwarden. On Wednesday September 26, in co-operation with partners, Cellvation organises a workshop on the pros and cons of resource recovery from sewage water. Prof. dr. Bruce Jefferson of Cranfield Water Science Institute (UK) will give a presentation titled Applicability of cellulose in a circular economy. You’re kindly invited to this workshop and can find more information about it here.

Innovative evaporator for corrosive liquids and gasses

The first evaporator completely made from high quality recyclable synthetic material 

With the development of an evaporator, built entirely from building blocks made of recyclable plastic, which can apply low-value residual heat as an energy source, CirTec brings the most sustainable evaporator to date to the market. By using high-quality recyclable plastic, the new design can be applied to thicken liquids in an exceptional wide pH-range from 1 to 14 at temperatures ranging from 30 to 100°C. The system, named CRESCENDO, consists of separate building blocks that can be modularly expanded for any desired capacity. Application of recyclable plastic combined with the, by CirTec recently launched, Active Vapor Recompression (AVaR), make the CRESCENDO or Synthetic GaLiCos™ evaporator the most sustainable evaporator available on the market.

This new evaporator will be launched officially at the IFAT on Wednesday May 16, 2018 at 1PM at Hall B2, booth 105/204

The CRESCENDO or Synthetic GaLiCos™ evaporator is a further development of a technology that has already successful been in operation for several years. In the basis, GaLiCos is an innovative, low maintenance technology, which allows evaporating highly concentrated liquid waste streams (brines) to the saturation limit. The operation is based on the principle that moisture is absorbed by unsaturated air. Using this principle GaLiCos enables both capturing salt crystals (as a concentration) in a partial flow limiting waste streams and production of distilled water by just using low-grade residual heat. As a result, GaLiCos™makes it possible to save energy, limit waste streams and create a closed circuit through the production of re-usable salt and water.

The CRESCENDO development is subsided by the Dutch government via the Partners for Water 2016-2021 subsidy programme.

We invite you to the official launch of CRESCENDO at the IFAT in Munich at Wednesday May 16, 2018 at 1PM at Hall B2, booth 105/204.

The CRESCENDO™concept has great added value above competitive systems. The main advantages are:

  1. Applicable for corrosive liquids and gasses in pH-range from 1 to 14 at temperatures from 30 to 100°C.
  2. Lower investment costs; systems are modular constructed and are relatively simple. A recirculating pump with limited head loss and a low-pressure ventilator are the only moving parts of the process.
  3. Reduced operating costs; The modules are not sensitive to scaling and are maintenance free. Further, the energy consumption is low and a plant can be operated without any significant attention.

About CirTec

For maintaining a good and healthy environment for future generations, it is crucial that we reduce the disposal of waste and encourage recycling of valuable components. CirTec aims to contribute actively to the sustainability of society and reuse of (waste) materials in particular.

With both proven and innovative technology, we are able to provide the most appropriate solution for a large number of environmental issues. We have a specific focus on the development of alternative raw materials such as recovered cellulose from municipal wastewater, the use of low value residual heat for evaporation of concentrated streams and we encourage recycling of waste and energy.
