Colloide solutions for effluent treatment are determined by site-specific factors including: existing plant size / capacity / condition; raw water quality; required final quality of treated effluent; space available; etc.

Activated sludge treatment uses microorganisms cultivated in the treatment process to break down organic matter into carbon dioxide, water and other inorganic compounds in sewage or industrial wastewater.

Activated sludge treatment features and benefits

  • Superior treated water quality

  • Flexible process - can be tailored to meet specific requirements

  • Low space requirements

  • Efficient single stage system

  • Reduced sludge production

  • Solid and liquid separation

  • Easily maintained mechanical work

Options

Conventional activated sludge treatment

Generally an aeration basin followed by settlement tank is used, sometimes with primary settlement. This basic form of treatment has been in use for a very long time and is suitable in many applications, particularly in the treatment of municipal effluent.

Advanced SBR

The Sequential Batch Reactor (SBR) is a compact and flexible solution to waste water treatment. Advanced SBR can deal with high BOD / COD loading while capable of producing effluent of a high standard. Manipulation of the SBR process allows control over many parameters whilst the reliability and ease of operation offers many advantages.

Membrane bioreactor

Membrane bioreactors provide high quality of treated effluent which is compact and offers the user a high degree of assurance over the performance of the plant. The membrane filtration achieves extremely low levels of solids removal and associated BOD removal. Plant sizes range from 1000l/day upwards.
