45
years of
experience
Specialists in process water and sludge treatment since 1981.
For over 45 years we have designed and built machines and complete plants for water recovery and the treatment and dewatering of process sludge. From laboratory analysis to on-site commissioning, you work with a single partner, in Italy and across 58 countries worldwide.
From a single machine to a turnkey plant: a full-service partnership with our customers.
Tecnoidea filter presses and plants have set the standard in process water and sludge treatment across many sectors.
Our solutions are reliable because of the way we work: we start by analysing the material matrix in our laboratory, design and size the process accordingly, and manufacture the machines and plants in-house, providing support from testing and commissioning through to ongoing operation.
This approach has guided us for more than four decades and is reflected in thousands of installations worldwide.

Our process technologies and products
Every Tecnoidea plant is based on extensive process expertise and continuous investment in technology, research and development. The same machines used in our turnkey plants are also available as stand-alone solutions, for revamping, upgrading or completing existing lines.
Clarification and storage
Clarifiers, tanks and storage vessels for solid-liquid separation and for managing water and sludge from aggregate washing.

Flocculation
Flocculant dosing units and automatic reagent dosing systems for the treatment of water and sludge from aggregate washing.
Learn more
Sludge dewatering
Overhead-beam or sidebar filter presses — robust, compact, pre-assembled and workshop-tested — custom-sized for dewatering sludge from aggregate washing, environmental remediation, road sweeping waste, concrete-mixer washing, tunnelling, drilling and stone processing.
Learn more
Water and sludge pumping
Abrasion-resistant pumps for turbid water, abrasive slurries and high-density sludge.
Learn more
Tertiary processes and ancillary systems
Advanced pH neutralisation and microfiltration systems, plus ancillary components that complete the plant.
Learn moreA single point of contact, from matrix analysis to plant installation and operation.
Every stage of the process is managed in-house by our team. This end-to-end control ensures that every plant operates efficiently and consistently within its design parameters.
Laboratory
We characterise the material through laboratory-scale washing, flocculation, physicochemical treatment, filtration and dewatering tests. We size your plant based on real data, not estimates.
Design
Our engineering team turns the data into a tailored design: from individual machines to the complete plant, including plant rooms, supporting structures and containment systems.
Construction
We manufacture and assemble our machines in-house, in our own fabrication and machine shops, while PLC programming is also carried out by our own specialized staff.
Installation & Service
On-site commissioning, operator training and ongoing technical support, backed by extensive spare-parts availability.
Specialised expertise in wash water and sludge treatment across a wide range of industries
Each industry presents different materials and process challenges. Our approach remains the same: we start with the material to be treated and the customer’s process requirements, then design the solution around them.
Quarries & Aggregates
Process water and sludge treatment plants for quarries and aggregate processing.

Learn moreWhy choose Tecnoidea for water and sludge treatment
Every machine — whether a filter press, a clarifier or a complete washing-water and sludge treatment plant — has to keep performing for decades. This is how 45 years of specialised industry experience translate into efficient, reliable plants built for long-term operation.
Physicochemical process expertise
Our expertise starts with material characterisation. This allows us to size the plant correctly and adapt the process when feed characteristics change.
In-house analysis laboratory
Every project starts with laboratory testing of the customer’s actual material. Our laboratory turns material testing into the process data needed to size and design the plant.
Over €3 million in spare parts in stock
Maintaining this inventory is a strategic choice designed to minimise plant downtime: when a plant stops, the real cost is not the part itself — it is the production downtime. Supplying directly from our own inventory allows us to respond quickly when a replacement is needed.
Continuous research and development
We invest in continuous research and academic partnerships — including our work with the Politecnico di Milano on PFAS, among today’s most challenging contaminants — to develop increasingly effective treatment technologies.
Trusted by customers in Italy and around the world.
Our plants operate in 58 countries worldwide
From Europe to India, from North Africa to South America, Australia and the Middle East: our process engineering adapts to every regulatory, climatic and logistical context. Know-how built in the field, one plant at a time.
Sustainability is the natural result of our work
Our plants can recover up to 95% of process water, reduce disposal volumes and help turn waste streams into secondary raw materials. At our production facility we have installed a photovoltaic system, and our vehicle fleet is transitioning to hybrid and electric vehicles.
Discover our commitment
The best technology, engineered for even the most complex matrices
We have always invested in research and development. We are working with the Politecnico di Milano on a PhD research project focused on PFAS — the so-called “forever chemicals” — to develop more effective and sustainable treatment processes.
We also develop our own software and automation systems, enabling advanced plant control, monitoring and Industry 4.0 integration.
