ACTIVATED SLUDGE TREATMENT
Conventional systems, sequential batch reactors for municipal and industrial wastewater treatment
Colloide have a range of solutions available for effluent treatment. The optimum solution is determined in each case based on parameters such as existing plant size/capacity/condition; raw water quality; required final quality of treated effluent; space available; etc.
The range of solutions include:
1. 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.

 2. ADVANCED SBR
The Sequential Batch Reactor is an extremely compact and flexible solution to waste water treatment. This 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 while the reliability and ease of operation offers many advantages.
Colloide Engineering Systems work with their partner Austep Engineering on these advanced plants.
3. MEMBRANE BIOREACTOR
This new form of treatment offers an extremely high quality of treated effluent which is very 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.
Advantages of this system include vastly superior treated water quality, reduced sludge production, low space requirements and an efficient single stage system.
