Biozone SBR Wastewater Treatment Plant

Biozone KENYA LIMITED: Biozone SBR (Sequential Batch Reactor) Wastewater Treatment Plant

The Biozone SBR (Sequential Batch Reactor) wastewater treatment plant provides on-site treatment of domestic and light commercial wastewater using a time-sequenced biological process within a single tank. SBR technology operates in a repeating four-phase cycle — fill, react, settle, and decant — that eliminates the need for separate clarifier tanks, making it well-suited to constrained sites and decentralised applications in Kenya’s growing peri-urban developments where sewer connections are unavailable.

Technical specifications

• Treatment technology: Sequential Batch Reactor (SBR)
• Process cycle: fill, react (aeration), settle, decant — all within a single reactor vessel
• Aerobic biological treatment using activated sludge process
• Produces treated effluent suitable for sub-surface irrigation or safe discharge
• Eliminates the need for a separate secondary clarifier
• Suitable for residential compounds, commercial premises, and institutional facilities
• Operates on a timed cycle controlled by automated sequencing

Sustainability features

• Single-tank design reduces material requirements and construction footprint compared to multi-stage treatment plants
• On-site treatment eliminates reliance on centralised sewer infrastructure
• Aerobic biological process avoids chemical treatment in standard operation
• Treated effluent can be reused for landscape irrigation, reducing freshwater demand
• Lower energy consumption than continuous-flow activated sludge systems due to batch operation
