DEQUACHIM – Expertise, Innovation & Long-Term Partnerships since 1983

Founded in 1983 by the Dequenne family, DEQUACHIM is a Belgian company strategically located south of Brussels, along the Paris–Amsterdam motorway. With over 38 years of expertise, we specialize in the production and marketing of high-purity aluminium salts (aluminium sulphate, sodium aluminate, potassium aluminate), boehmite and pseudoboehmite aluminas, aluminium oxide, and potassium nitrate.

A trusted and agile partner
As an independent and highly responsive company, we serve leading industrial players across a wide range of sectors, including water treatment, fertilizers, catalysts, abrasives, coatings, pigments, concrete and cement additives, paper, photography, ceramics and refractories, pharmaceuticals and cosmetics, pyrotechnics, and coke oven gas desulphurisation.

More than 70% of our production is exported, mainly to Europe but also worldwide. Together with our clients, we co-create and develop tailored products and solutions, always with a long-term partnership mindset.

Quality, innovation, and sustainability
Our reputation is built on a dynamic team, continuous investment, and a forward-looking approach. DEQUACHIM is ISO 9001:2015 & Ecovadis certified, and officially recognised by the Walloon Region as a recovery centre for hazardous and non-hazardous waste containing aluminium.

Since 2013, we have invested in 7,900 photovoltaic panels generating 3,700 kW of electricity, reflecting our strong commitment to sustainable development.
