What Aqseptence Group does

Aqseptence Group is a German-headquartered industrial equipment and solutions provider in filtration, solid-liquid separation, and water/wastewater technology, serving municipal water utilities, public authorities, and industrial customers across sectors including mining and metals, power generation, oil and gas, chemical and pharmaceutical, food and beverage, pulp and paper, and desalination. The company operates as a multi-brand holding structure whose constituent brands carry deep heritage (Noggerath founded 1884, Geiger 1891, Johnson Screens 1904), consolidated into the current group through mergers in the 2000s and formally organized under the Aqseptence name. It is privately held, majority-owned by funds managed by Oaktree Capital Management since a controlling-stake acquisition closed in November 2023, with management retaining a minority interest.

The group organizes its offering into three core segments: Filtration and Thickening Systems (Diemme Filtration — filter presses and thickeners), Screening Technology Systems (Johnson Screens — Vee-Vire wound-wire screens for water wells, industrial, energy, and architectural applications), and Water Processing Solutions (Passavant, Geiger, Noggerath — mechanical pretreatment, intake screening, sludge treatment). Specialized adjacencies include Roediger and Airvac vacuum sanitation and vacuum sewer systems, and B-PLAS, which converts wastewater sludge into biodegradable bioplastics (PHA). Proprietary technologies include Roediger vacuum sanitation (deployed in hospitals for 40+ years), Geiger MultiDisc fish-friendly intake screens, the Johnson Screens Triton underdrain, and Aqualogic/Enerlogic plant-control systems, complemented by a Roediger SMART remote-monitoring capability accessible via smartphone.

The company monetizes primarily through the sale of engineered, custom-quoted equipment and integrated systems (hardware sales), supplemented by a recurring aftermarket stream of operation and maintenance contracts, annual service agreements, block-hour services, spare parts, site surveys, and operator training. Go-to-market is enterprise field sales, executed through brand-specific sales organizations and dedicated brand websites, targeting blue-chip industrial and municipal accounts globally. Pricing is not publicly disclosed and is quote-based, reflecting complex, project-driven capital equipment sales. The group reports roughly 1,300–1,600 employees (declining toward 1,300 following the pending Diemme divestiture), around 20 legal entities and 26 integrated locations, and has been recognized as a WirtschaftsWoche "Global Market Leader"/Hidden Champion for four consecutive years (2023–2026).
