How Do Domestic Wastewater Treatment Plants Work?

The first step in understanding how domestic wastewater treatment plants work, is knowing what classifies as wastewater and where it comes from. Domestic dwellings that produce wastewater include homes, shops, offices or factories, while sources of wastewater include toilets, showers, baths, kitchen and laundry sinks. While wastewater is often viewed as dirty or biologically dangerous due to germs and bacteria, the reality is that 99.9% of wastewater, by weight, is simply just water; 0.1% of wastewater is a mixture of excrement, detergent, foods etc. It is evident through this description why the treatment and recycling of water is imperative for our future.

In acknowledging how both important and finite water as a resource is, EcoSeptic offer two interrelated yet independent domestic wastewater treatment plants – a chemical/physical and a biological wastewater treatment plant. The chemical/physical option relies specifically on chemical reactions to oxidise waste, whereas the biochemical approach relies on biological matter, namely bacteria to break down waste contents. Either option is safe, environmentally friendly and effective.

Chemical/physical wastewater treatment:

This is also known as the Primary Treatment of water. In this process, solid and/or large waste is physically removed from the water via chemicals purposed with oxidising waste into smaller particles that can then be biochemically digested by bacteria.

Biochemical wastewater treatment:

This is commonly referred to as the Secondary Treatment of water. Here, microorganisms transform the dissolved organic matter into a dense biomass that can be separated from the treated wastewater by the sedimentation process, and in the same process, use this process as a way of generating food and energy for themselves.

The overarching aims of wastewater treatment:

  • Protecting public health by ensuring access to pure water.
  • Ensuring the materials sourced from wastewater can be adequately disposed of and/or reused if appropriate.
