Sewage Treatment Package Plant

Veolia’s Sewage Treatment Plants (STP™) are a fully containerised treatment solution for sewage from 25 to 200 m3/day. A hybrid solution utilising a civil-based septic tank can treat up to 600 m3/day.

The STP™ incorporates trickling filter technology, a simple but versatile technology that is easy to operate and requires very little maintenance. Manufactured as part of our Water Techno Packages range in Johannesburg, these off-the-shelf, plug-and-play plants can be manufactured in as little as 12 weeks for rapid deployment.

Sewage Treatment Package Plants Built For Africa

When it comes to municipal wastewater treatment in Africa, sewage treatment systems need to be reliable, adaptable and low maintenance. One of our key solutions currently meeting these objectives is Veolia’s proprietary trickling filter solution. Designed to be fitted into a compact container, this sewage treatment package plant ensures:

  • digestion processes recover easily after power outages;
  • less sludge is produced;
  • peak flows are easily accommodated;
  • lower energy requirements; and
  • minimal routine maintenance.

A single trickling filter sewage treatment process system is can cater for a community of up to 5 000 people. This makes it ideal on a range of sites, including mine camps, remote settlements and communities!

Trickling filter technology is centred on a bed of highly permeable media that allows micro-organisms to form a biological film. Domestic wastewater trickles through this film, absorbing any organic material. This process is typically incorporated into a holistic sewage treatment package plant that includes rough screening, a septic tank for anaerobic digestion, a settling stage and final disinfection steps.

The sewage treatment process begins with pre-treatment, which removes non-digestible particles using filtration techniques. Sewage then enters the anaerobic reactor where all organic particles are broken down. These particles are removed from the water using ultra-compact clarification technology, leaving the water ready for disinfection using either chlorination or ultraviolet treatment.
