Twincad S.r.l.
About
Twincad S.r.l., based in Costa di Rovigo, Italy, designs and manufactures machines and complete turnkey plants for water and wastewater treatment, along with pumping stations for land reclamation and industrial applications. With over two decades of experience, the company produces its full equipment range in-house at a 3,500 m² metalworking facility staffed by specialized carpenters and welders. Twincad's product catalog spans thirteen lines: sluice gates (Paratoie) for channel and tank flow control; Archimedean screw pumps (Coclee) for lifting wastewater and sludge; bar screens (Griglie) for influent debris removal; peripheral traction bridges (Ponti a trazione periferica) and traveling bridges (Ponti va e vieni) for clarifier and sedimentation tank scraper operation; sludge thickeners (Ispessitori per fanghi) for gravity thickening; sand separators and classifiers (Dissabbiatori e classificatori); compacting presses (Presse compattatrici) for screenings dewatering; conveyor belts (Nastri trasportatori); overflow weirs (Sfioratori); self-dumping tanks (Vasche autoribaltanti); lamella pack clarifiers (Sedimentatori a pacchi lamellari); and wine lees treatment systems (Trattamento bottini). The company serves land reclamation consortia, slaughterhouses, industrial laundries, aqueducts, and water utilities, offering complete design-through-commissioning services including engineering, fabrication, installation, testing, and ongoing R&D for custom-tailored solutions.
Key Products
Flow control gates for channels and tanks in water and wastewater treatment plants, available in various sizes and configurations.
Helical screw pumps for lifting and conveying water and wastewater, used in lift stations and treatment plant influent/effluent.
Mechanical screens for removing debris, rags, and screenings from wastewater influent to protect downstream treatment equipment.
Rotating bridge-mounted scraper systems for circular sedimentation tanks and clarifiers, collecting settled sludge and floating material.
Reciprocating bridge systems for rectangular clarifiers and sedimentation tanks, scraping settled sludge to hoppers.
Gravity thickening equipment for concentrating wastewater sludge, reducing volume before further dewatering or digestion.
Grit chambers with classification capability for removing and washing sand and grit from wastewater influent.
Mechanical presses for dewatering and compacting screenings, reducing volume for disposal or further processing.
Transport systems for moving screenings, grit, sludge, and other materials through treatment plant processes.
Weir and overflow structures for controlling water levels and directing flow in tanks and channels during high-flow conditions.
Automatic tipping tank systems that periodically discharge accumulated material for controlled batch processing.
High-efficiency clarifiers using inclined lamella plates to increase effective settling area and reduce required footprint for sedimentation.
Treatment systems for processing barrels and tuns, typically in industrial or agricultural wastewater applications.
