Diemme Filtration - Filtration & Thickening Systems

What Diemme Filtration - Filtration & Thickening Systems does

Diemme Filtration srl is an Italian-headquartered specialist manufacturer of solid-liquid separation equipment, founded in 1923 and based in Lugo (Ravenna), Italy. The company designs and produces a broad portfolio of filter presses (GHT-F, GHT5000F DOMINO, GHT-P, GHS, ME, AUTOMAT, KE series), thickeners, and auxiliary pumps, customized for industrial dewatering applications and supported by an in-house laboratory, engineering, and R&D function. End markets span mining and metals (primary), chemical and pharmaceutical, food and beverage, oil and gas, power generation, quarrying and recycling, dredging and soil remediation, red mud (bauxite residue), second-generation bioethanol, and municipal/industrial wastewater treatment.

The company earns revenue primarily through capital equipment sales and full project services — design, manufacturing, installation, and commissioning of turnkey solid-liquid separation facilities, typically awarded via competitive bidding following laboratory testing and pilot-plant trials. Pricing is project-specific and not publicly disclosed. Distribution is a direct enterprise field-sales motion globally, with multi-language coverage (EN, IT, ES, FR, DE, PT, RU) and sector-specific event presence.

In 2026, Diemme materially extended its product surface beyond hardware with three coordinated launches: the AIDA System Tutor IIoT platform (April 2026) for real-time diagnostics and predictive analytics; Optycare (May 2026), a patent-protected AI-based filter-cloth diagnostic device; and X-Change (May 2026), a patent-protected intelligent system for filter media replacement. These launches mark an explicit shift from pure equipment sales to a service- and data-rich ecosystem. In June 2026, Sandvik Group announced the acquisition of Diemme from Aqseptence Group (backed by Oaktree Capital Management); Brazil's antitrust authority CADE cleared the deal in July 2026, and Sandvik completed the acquisition in Q2 2026 — Sandvik cited expected FY2026 revenue of SEK 1.1 billion for Diemme and framed the deal as its entry into mining filtration and dewatering.
