Compact clariflocculation upstream of planted filters for wine effluents
Addition of a compact clariflocular between aerated buffer tank and filters planted with reeds to relieve a wine WWTP overloaded with suspended solids.
Compact, modular and easy to operate, this clariflocculation unit protects the filters, stabilizes the flows and secures the harvest campaigns with compliant rejects.

Project Background
A winemaking station saw its filters planted with reeds saturate under high loads of suspended solids.
Designed for maturation, these initial stages were no longer able to guarantee regulatory performance, with an increased risk of exceeding them during periods of high activity (harvest).
It was necessary to relieve the reed die without recasting the entire installation.
Objectives
- Reduce the load of suspended solids upstream to stabilize flows,
- Protecting existing structures and extending their lifespan,
- Integrate a compact, modular and easy-to-use solution,
- Ensure rapid commissioning and sustainable compliance.
Technical solution
Installation of a compact clariflocculator including:
- coagulation
- flocculation
- lamella settling.
Positioned between the aerated buffer basins and the planted filters, it captures fine particles, regulates the flow rates and greatly reduces the solid load sent to the filters.
The whole thing is turnkey, ready to connect, designed to integrate easily into existing infrastructures.
CNC prefabrication & modularity
- Compact unit, separable modules for easy installation,
- Limited connections = reduced installation times,
- Integration possible without heavy work,
- Modular architecture for future expansions.
On-site implementation
- Simplified transport thanks to compactness,
- Establishment in a small space,
- Quick hydraulic/electrical connections,
- Commissioning including: reactive adjustments, purge plan, visual control, turbidity/flow monitoring.
Results
- Net reduction of suspended solids sent to planted filters,
- Stabilized reed filter, more regular supply chain,
- Compliant discharges and more predictable operation,
- Extension of the life of structures,
- High-performance station without additional civil engineering.
Operation & Maintenance
- Simple procedures: sludge purges, visual checks, reactive adjustments,
- Easy operator access,
- More regular operation thanks to the stabilisation of flows,
- Less fouling = less intervention and costs.
Key figures
- Complete clariflocculation — coagulation + flocculation + lamellar
- Reduced suspended solids load – immediate protection of planted filters
- Fast integration — no heavy work required
- Sustainable supply chain — extended filtration and enhanced compliance
- Modular solution – scalable according to the harvest season
Product focus: Compact clariflocular (CFCE. DLCE)
To effectively reduce the suspended solids load before the reed filters, we installed a compact clariflocculator combining coagulation, flocculation and lamellar settling.
Designed for wine effluents, it captures residual particles, regulates flows and stabilizes the sector while remaining space-saving.
Thanks to its modular design, it can be easily integrated into existing buffer basins and filters without heavy work. Its in-line operation — mixing, floc formation and then accelerated separation in the lamellae — protects the structures, improves the performance of the rejects and makes the operation more regular.
To keep costs down and speed up commissioning, this unit is turnkey, plug-and-play, with reduced connections and easy access for purges and maintenance.
- Complete Clariflocculation
- Strong reduction in MES
- Compact lamellar
- Easy integration
- Protection of planted filters
Steps to collaborate
- Diagnosis of wine effluents — suspended solids, seasonal variations (harvest), constraints of planted filters.
- Sizing of the clariflocculator — reagents, contact time, flocculation volumes, lamellar surface.
- Preparation & logistics – delivery of the compact module, limited hydraulic connections.
- On-site commissioning — timing of dosages, hydraulic adjustments, sludge purge plan.
- Monitoring & optimization — support at the start, adjustments according to harvest seasons.
