AAQUA

What AAQUA does

AAQUA is a Belgian industrial water treatment specialist that designs, builds, and operates custom wastewater treatment installations under Design-Build-Operate (DBO) contracts for industrial clients. Founded in 1998 by Marc Feyten and headquartered in Sint-Katelijne-Waver, Belgium, the company serves manufacturers and processors across food and beverage, paper and packaging, metal, chemical, pharmaceutical, tank cleaning, and brewery sectors, with a reference portfolio of 200+ clients spanning 13+ countries including Belgium, France, Germany, Hungary, Saudi Arabia, Thailand, Malaysia, and the United States.

AAQUA's technology stack combines physicochemical and biological treatment modules — sieving, coagulation and flocculation, Dissolved Air Flotation (DAF) achieving 90%+ suspended solids removal, biological treatment, and sludge processing — integrated into purpose-built plants with proprietary automation (in-house since 2003) and standard remote monitoring (since 2006). A distinctive capability is water reuse, where AAQUA purifies wastewater to process water or drinking water quality; the firm achieved Belgian (2015) and European (2020) firsts in this domain. A mobile treatment fleet supports pilot testing and temporary capacity, lowering customer commitment barriers. Since 2016, AAQUA has operated as part of the French Aquaprox group while retaining operational autonomy, and acquired Interindus in 2017 to strengthen process water production expertise.

Revenue is generated through project-based custom DBO contracts with multi-year billing cadences; pricing is not publicly disclosed. By 2021, water reuse projects contributed 30% of turnover, up from a negligible share in 2017, signaling a deliberate mix shift toward higher-value circular water solutions. The go-to-market is consultative enterprise field sales with no channel or reseller distribution, supported by a multi-language website and direct contact channels.
