Case study
Our client had a capacity of 300 MW and used Ion Exchange Resins (IER) technology and fresh water to produce ultra-pure demi water needed for high-pressure steam.
Nearly US$3 million

Case narrative
In 2010, the client issued a public tender to design, manufacture and supervise the installation, start-up, commissioning and service of a desalination plant with the capacity of producing 2,520 m3/day of ultra-pure water for the power plant.
Technology, equipment quality, warranties, technical assistance and costs were the parameters taken into consideration for awarding the project. The technology and scope proposed by Chematek included seawater uptake and pre-treatment with multimedia filters (Installed Capacity – IC: 420 m3/h), desalination with two-pass Reverse Osmosis (IC: 150 and 135 m3/h), demineralisation with Mixed Bed Resins (IC: 180÷360 m3/h) and neutralisation of wastewater. The proposed plant had a high level of automation to guarantee high reliability and safety. The proposal also included a three-year contract for providing technical assistance and training the power plant personnel.
Chematek was awarded the contract in April 2011 and the plant started its operation in December 2012, becoming the first of its kind in the area.
Case narrative
The consumption of chemical products dramatically decreased after Chematek installed the new desalination plant, and all brine and residues are now neutralised and safely sent to the sea.
Considering the reduced consumption of chemical products, fresh water and electricity, the client is saving nearly US$3million and 1480 MWh per year, compared to the use of previous IER technology.
Our client had a capacity of 300 MW and used Ion Exchange Resins (IER) technology and fresh water to produce ultra-pure demi water needed for high-pressure steam.
Fresh water, however, is a limited resource in the area and using it was decreasing its availability to the local population.

Chematek has been awarded funding for the COFREE – CARB project within the framework of the European Regional Development Fund Programme FESR 2021–2027 of Regione Lombardia, under Action 1.1.2 “Support to technological transfer between Research and Lombardy companies”.
Chematek is proud to announce the publication of a significant research paper in *Organic Process Research & Development*, a leading peer-reviewed journal published by the American Chemical Society. The paper presents a comprehensive review of Synhydrid chemically known as Sodium bis(2-methoxyethoxy)aluminium hydride, or SDMA one of Chematek's flagship organometallic reducing agents. This publication marks a major scientific milestone for the company, representing the culmination of years of research into a reagent that Chematek has championed as a safer, more efficient alternative to traditional reducing agents.
SK Ecoengineering required a water treatment plant for a new factory in Poland manufacturing a lithium-based substrate, which is then supplied to another factory in Hungary producing automotive batteries.
