DECLA lamellar decanters are suitable to separate large amounts of suspended solids, filtering larger flows and smaller footprint than conventional sedimentation, and providing higher efficiency. Decanter is designed for treatment of drinking water and waste water. Three areas are distinguished: • Inlet area: A pipe evenly distributes the previously flocculated water to lamellar module. • Settling area: It is composed of lamellar modules with 60º inclination. • Sludge area: Lower settling zone where the sediment particles are accumulated. Equipped with outlet system for purging. Standard models with capacities ranging from 5 m3/h to 200 m3/h, calculated with upward water speed equal to 0.8 m/h and depending on the type of sludge to treat.
