Kemira to add ACH line

Kemira has revealed a planned €20 million investment in a new aluminium chlorohydrate (ACH) line at its site in Tarragona, Spain. The company expects the line to be commissioned in early 2028, following the completion of permitting processes. It will be built using technology already in use at Kemira’s facilities in the US and Poland.

ACH is a high-performance coagulant that is primarily used in drinking water treatment. It has a “significantly higher” aluminium concentration compared to conventional products such as aluminium sulfate and standard polyaluminium chloride, the company said. It is also claimed to offer superior performance in removing colour and particles from raw water, especially during heavy rainfall and flooding, which is a growing issue for many large cities across Europe.

The project is expected to have minimal environmental impact, supported by the use of renewable energy and ongoing evaluation of mitigation measures for the small share of emissions from natural gas usage.
