Colloide design and install Sequential Batch Reactors. With flexible plants, and various aeration options they are capable of completing the treatment process in one tank. Despite the compact bulk free design Coilloide's SBRs are capable of treating high incoming loads with no recirculation pumps and minor energetic consumption.

  • Compact – the complete process occurs in one tank

  • Complete automation and remote operation of the plant

  • Highly reliable and easy to operate

  • Ability to treat high incoming loads

  • No bulking problems

  • Flexible plants, with various aeration options

  • No recirculation pumps and minor energetic consumption

The SBR process is based on biological treatment of wastewater. In this process, the incoming wastewater is treated on a batch basis – hence the name Sequential Batch Reactor (SBR).

The influent wastewater enters the SBR tank during the programmed load time. Aeration and mixing (or only mixing) phases allow nitrification and denitrification of the nitrogen present in the wastewater. At the end of the treatment, the aeration and mixing stop and the biological sludge settles in the reactor. The treated effluent is then collected from the top of the SBR tank.

This complete process takes place in one tank, leaving the process very compact. Colloide can aerate, mix (with and without oxygen), chemically dose and settle in this SBR tank, with excellent process flexibility.

One or more tanks can be used in parallel depending on plant requirements.

Applications

Wastewater

Due to the flexibility and high performance levels, Colloide can use its SBR plants on a wide range of wastewaters. In all cases, the plant is designed specifically for the particular wastewater. The company has used SBR technology successfully on applications in the treatment of many fields including municipal wastewater, leachate (landfill effluent) and industrial wastewaters.

The SBR performs particularly well in the treatment of effluent highly loaded in both COD and / or ammonia, achieving up to 98% removal of bio-degradable COD and total removal of ammonia. It also has excellent nutrient removal properties.
