The compact, self-contained version of the Combi Pro, developed for small WWTPs, condominiums, hotels and low-flow applications. Combines automatic screening and grit removal in a vertical compact stainless steel structure, installable in confined spaces.
The Combi Pro Mini is the miniaturized version of the Estruagua Combi Pro line, designed specifically for smaller applications where available space is limited. The compact vertical structure in stainless steel integrates automatic screening and grit removal in a single low-impact, easy-to-operate unit.
Installed on an elevated platform with safety handrails, the Combi Pro Mini requires minimal civil infrastructure and operates completely automatically. The two inclined screw conveyors (one for screened solids and one for grit) remove and transport the waste to the discharge points, keeping the operating area clean and safe.
Vertical structure with a small footprint allows installation in locations with severe space constraints.
Vertical body and all conveyors in stainless steel for maximum durability and hygiene.
Factory pre-assembled unit with simplified connection to pipework and electrical supply.
Raw sewage is admitted through the inlet duct at the bottom of the unit and passes through the screening mechanism integrated into the vertical body. The automatic screen retains coarse and fibrous solids, which are collected and transported upward by the inclined screw conveyor, discharging the waste into a container positioned below the discharge point.
The screened effluent flows into the grit removal chamber, where the internal geometry promotes flow velocity reduction and settling of sand and mineral particles. The grit classifier screw continuously withdraws the settled material, dewatering it before disposal, ensuring grit with low moisture content and minimised odours.
Raw sewage enters and the automatic screen retains coarse and fibrous solids.
Inclined screw continuously elevates and discharges the retained solids.
Grit chamber removes sand; classifier screw extracts and dewaters it before disposal.
