About
Quilton S.A. is a Spanish manufacturer based in Bilbao that designs and builds mechanical equipment for water and wastewater treatment. The company's product range centers on four categories: screens and bar screens, screw conveyors and classifiers, waste compactors, and compact treatment systems. Named products include the self-cleaning continuous screen, chain bar screen, water intake filter (filtro de captación), horizontal bar overflow screen, compact pre-treatment plant, screw compactor, sand classifier, elevating screw conveyor, textile filter for tertiary treatment, and rotary screen. Quilton serves three water sectors: wastewater treatment, industrial water, and stormwater overflow management. The horizontal bar overflow screen is specifically designed to comply with Spain's Real Decreto 665/2023 for combined sewer overflow treatment. The company provides full-cycle services from engineering design through manufacturing, assembly, commissioning, and after-sales support, and is a member of FLUIDEX, the Spanish association of fluid handling equipment exporters. Quilton's equipment is installed in major infrastructure including the EDAR de Galindo wastewater treatment facility.
Key Products
Automated screening system with continuous belt that removes suspended solids from wastewater without manual intervention, providing reliable headworks protection.
Mechanically cleaned bar screen using chain-driven rakes to lift and remove coarse solids from wastewater channels at treatment plants.
Screening and filtration equipment for raw water intake points at treatment plants, protecting downstream processes from debris and aquatic organisms.
Horizontal bar screen designed for stormwater overflow management, complying with Real Decreto 665/2023 for combined sewer overflow treatment.
Integrated pre-treatment station combining screening, grit removal, and compaction in a compact footprint for small to medium wastewater treatment facilities.
Screw-based dewatering and compacting system that reduces volume of screened solids by pressing out water, achieving higher dryness than conventional conveyors.
Equipment that separates, washes, and classifies grit and sand from wastewater, removing inorganic solids to protect downstream treatment processes.
Screw conveyor system that transports and elevates screened solids, grit, or sludge vertically or at an incline for discharge into containers or further processing.
Cloth/media filter system for tertiary wastewater treatment that removes fine suspended solids and provides high-efficiency polishing of effluent.
Rotating drum or disc screening device that separates solids from wastewater through a rotating screen surface, suitable for fine screening applications.
