Mechanical Pretreatment Equipment
The essential first stage in the wastewater treatment process. Mechanical pretreatment equipment removes coarse solid materials to protect downstream equipment and improve treatment process efficiency.
Screw Screens
Compact screening and conveying systems in a single unit. Automatic waste separation and compaction, with significant moisture reduction. Ideal for small and medium plants.
Sewage Grinders
Grinders for shredding solid materials from wastewater: rags, plastics, wood and other objects. Protects downstream pumps and equipment.
Mechanically Cleaned Bar Screens
Fixed and mobile bar screens with automatic rake or chain cleaning. Various bar spacings (3-100 mm) for coarse or fine separation.
Drum Screens
Rotary drum screens for fine separation (0.5-6 mm). Continuous operation with self-cleaning, ideal for stormwater treatment and pre-filtration.
Grease Separators
Equipment for removing oils and grease from wastewater. Essential for food industry, restaurants and industrial applications.
Grit Chambers
Basins for separating sand and heavy mineral materials. Protects pumps from abrasion and prevents accumulation in treatment basins.
Waste Compactors
Presses for compacting and dewatering waste from bar screens and sieves. Volume and transport cost reduction.
