ABIONIK

What ABIONIK does

ABIONIK (formerly Abionik Group; since 2021 operating as Wilo Water Treatment, a division of Wilo SE) provides integrated water, wastewater, and exhaust air treatment solutions that combine mechanical, biological, membrane-based, hydraulic, and air treatment processes. The portfolio is delivered through four retained sub-brands: Wilo FSM (mechanical water and wastewater treatment — screening systems, sieve machines, grit removal); Wilo Likusta (exhaust air and gas treatment, odor reduction, and chemical-water dosing); Wilo Martin (compact MBR / membrane bioreactor systems for municipal, industrial, and maritime applications); and Wilo Steinhardt (stormwater management, flood protection, and sewer hydraulics). Together these brands address solids removal, biological treatment, effluent polishing, odor and emissions control, and urban stormwater resilience.

ABIONIK was founded in 1978 and headquartered in Berlin, Germany, and was acquired by the Wilo Group in 2021; the legal entity is now Wilo SE, a private German corporation. Following the deal, the four constituent brands were preserved as sub-brands and reorganized under a unified Wilo Water Treatment division, positioning the combined entity as a "holistic, single-source solution provider" across the full treatment stack. The business model is B2B capital-equipment sales and project/services for water and air-treatment installations (pricing is not publicly disclosed), and operations are supported by Wilo Group's global distribution and service footprint.

Customers are organized into three primary verticals: municipalities (water/wastewater plants, stormwater, flood defense, emissions compliance); industrial companies (process water, industrial wastewater, emissions control under tighter regulation); and maritime operators (compact MBR systems where space constraints and high effluent quality drive specification). The combined offering targets megatrends of urbanization, stricter environmental regulation, increasing extreme weather events, and aging water infrastructure, with stated applications across municipal, industrial, and maritime end-markets worldwide.

Core offering

ABIONIK (now organized within Wilo Water Treatment) designs, manufactures, and supplies water, wastewater, and exhaust air treatment systems. Its portfolio spans mechanical treatment (screening, sieve, and grit removal systems), membrane-based biological treatment (compact MBR systems), exhaust air purification and odor reduction, precise chemical dosing, and stormwater management and flood protection solutions for municipal, industrial, and maritime customers.

Product overview

Wilo Water Treatment is a unified division combining four acquired sub-brands (Wilo FSM, Wilo Likusta, Wilo Martin, and Wilo Steinhardt) following Wilo's acquisition of Abionik Group in 2021. The portfolio integrates mechanical, biological, membrane-based, hydraulic, and air treatment processes to serve municipalities, industrial companies, and maritime customers as a single-source solution provider for water, wastewater, and exhaust air treatment.
