Causes and Solutions to Wastewater Treatment Odors

Wastewater treatment plant stench is common; bearing in mind they collect waste matter from various places – residential, commercial and industrial sources. The level of treatment in various plants differs; but one thing they have in common, is their extent of releasing an unpleasant smell. So, what are some of the major causes of treatment plant odors?













  1. Rising temperatures

As the outdoor temperatures rises, for instance during summer, the wastewater temperature also increase. Consequently, aerobic bacteria become dreadfully active and start digesting BOD and other nutrients even at a quicker rate. The warm the water gets the more active these bacteria are; and in turn, the more oxygen they use. This usually results in low dissolved oxygen.

     2. Anoxic zones

Low dissolved oxygen together with rising temperatures can possibly make anoxic zones to multiply at the base of wastewater aeration basins. More often than not, anaerobic digestions releases sulphur dioxide, besides other noxious gases which cause wastewater odor.


  1. Increase oxygen supply

Increasing oxygen supply ensures that the bacteria have adequate oxygen vital to aerobically digest BOD. Obviously, this will help minimize odors as anaerobic digestion will drop off.

     2. Water circulation

Ensuring dissolved oxygen is adequately reaching every part of the aeration basin is crucial to avoiding odor. This can be achieved by circulating wastewater in all parts of the plant; and virtually, it will ensure that the much-needed oxygen is dissolved evenly.

In a nutshell, a very pungent odor is a sign that wastewater is being undertreated. An irritating smell can affect the industry workers or people living nearby if left unhandled. Therefore, next time there is an odor coming from your plant; make an effort of taking the above steps.

Removing Sulphate from Wastewater: A Process That you Must Consider

Sulphate is a well-known chemical that can be found in many areas including wastewater treatment plants. While it does not have harmful effects on the human body in low levels, sulphate acts as a laxative when consumed in high quantities. In regards wastewater, it is very important to get rid of sulphate due to the damaging effects it has on the ecosystem.


Effects of sulphate on the environment

Sulphate has been confirmed to cause all types of problems to the ecosystem. To begin with, it has a substantial negative impact on the aquatic environment. For instance, if it gets into streams and rivers, it poisons the marine life. Secondly, it is one of the contributors of acid rain. It is for this reason that sulphate elimination has become so vital in the wastewater industry.

How is sulphate removed?

There are several procedures used for sulphur elimination from water. Precipitation and membrane separation are two known methods. However, the most popular method is the biological method. This is not a surprise since it is more cost effective and consumes less energy compared to other methods.

There are a number of benefits that are associated with sulphate removal process if it is carried out properly. They include:

  • Removal of other harmful contaminants besides sulphate
  • Water could be re-used after sulphate is removed
  • It’s a lime scale-free process

Overall, this process is important for any industry which has sulphate in their wastewater treatment system. There are several environmental regulations relating to sulphate which companies need to observe. If you are doubtful about these requirements, it is absolutely worth looking them up.
