Clarified Water Decanter

The Biogest DKW clarified water decanter is a floating weir system that withdraws treated water from SBR tanks after the settling phase without disturbing the settled sludge blanket. DKW operates by gravity — no pump required — minimizing energy consumption.

Key specifications:

• Self-adjusting float: Tracks changing water levels in SBR tanks
• Low withdrawal velocity: <10 mm/min — prevents sludge entrainment
• Scum guard inlet: Blocks floating matter and surface scum from entering discharge
• Throughput: 50–3,000 m³/batch depending on size
• Materials: SS316, HDPE; maintenance-free design
