Treating effluent streams

What is an effluent stream?

An effluent stream is the flow or course taken by wastewater made ‘dirty’ by the industrial process it serves. It may be within a plant combining with others in the factory, or from the factory it may converge with a municipal sewer which will then be carrying mixed effluent.

There are different types of effluent streams. For example:

  • A sewer carries a sewage stream, which is usually made up of a mixture of domestic, catering and a small percentage of industrial effluent (depending where in the urban area the stream is situated).
  • A dairy or cheese factory discharges a dairy effluent stream, normally high in curds and milk/butter fat wastes.

In any event, each stream of like effluent should be pre-treated before mixing with a different type of effluent. For instance, blood effluent (organic COD) and tank wash effluent (caustic chemicals) in an abattoir. This should be done prior to discharge from the premises. Why? Microorganisms are substrate selective and there is no one ‘super bug’ that will degrade everything.


Common effluent stream problems

  • Ignorance is one of the most common problems. Often the plant designer does not know how to handle the effluent stream, neither do operating staff.
  • Incorrect devices are used. For example, static screens (which tend to block) are utilized instead of the more expensive (and correct) rotary screens.
  • Frequently, the lack or paucity of finances allocated to the project are also to blame. Since it is ‘waste’ water that is being removed the budget is often cut and inferior or undersized equipment is installed to reduce operating costs.
  • Production volumes are also culprits: the capex option for average flow, which was taken when the business started, increases as the business grows and the maximum flow (peak at start-up) proves to be the norm.


The BIO-SYSTEMS solution

For the conveyance and treatment of effluent streams BIO-SYSTEMS offers a three-prong approach:

  1. Consultancy

    We have ready access to a number of experts in the effluent field (especially in Southern Africa). We know where to find the right people experienced in specific effluent streams who have tried and tested various treatments. We can assist with the design of systems to suit any challenge and our formidable bank of case histories (both local and international) prevent our clients from having to ‘re-invent the wheel’.

  2. Equipment

    Our network encompasses specialist manufacturers from whom most effluent treatment devices are obtainable. Grease interceptor traps play a primary role in cleaning up catering and mechanical effluents. They are never used on sewage lines.

  3. Additives

    We have specific additives, mostly comprising natural bacteria, with which to improve the quality of most effluent streams.
