Types of sewage treatment plant

types of sewageTypes of sewage treatment plant

Tricel is a global manufacturer of high-quality products and produces several types of sewage treatment plant.

Changing sanitation can be a complicated task. Indeed, a large number of products are available on the market. In addition, the technical differences can be very significant from one product to another or very small.

Therefore, before you embark on this project, it is necessary for you to know:

  • your needs,
  • your budget,
  • the options available,
  • the regulations.

In this article, we will focus on the different types of sewage treatment.

types of sewageFixed bed

Sewage treatment plants are usually considered as the most suitable technology for individual homes. In fact, they generate little sludge. They also record the best results in terms of load variation.
Explanation: Indeed, the bacterial flora, which is fixed on the support that offers them the “bacterial bed”. They develop themselves on this bed depending on the incoming charges of wastewater. It follows a “self-regulating” principle. In addition, the recirculation of residual sludge to the primary clarifier allows feeding the bacteria during prolonged absences of the occupants of the house.

Tricel uses this process with the Tricel Novo sewage treatment plant, that we consider as a top-quality product in terms of technology and material.

If you want more information about this process or about our Tricel Novo, please contact us or download our brochures.

Free bacterial culture

The free bacterial culture sewage treatment plant, is the most common technique used for collective sanitation.

On this free bacterial culture technology, two families are available on the market, the activated sludge sewage treatment plant, and the other, the Sequencing Batch Reactor (SBR).

Activated sludge

The activated sludge sewage treatment plants are very sensitive to load variations, and therefore doesn’t really suits the needs for a house. In fact, the activated sludge products don’t tolerate big absences (summer holidays, visitors during weekends etc..).
The results for the activated sludge sewage treatment plants are:
More sludge generated

  • highest emptying cost,
  • bacterial flora regularly degraded,
  • smell problems.

Sequencing batch reactor (SBR)

The SBR technology is a much more complex version of the activated sludge. In fact, with this technology, the sludge remains in a single tank (most of the time) and is treated during a 3-phase process. A relatively complex onboard electronic system makes it possible to manage phases during which the wastewater will be decanted, then clarified and then evacuated. This technology, supports load variations. Indeed, the user will be able to settle the system, before his absences. It’s the same principle, if more people are present.

This technology is effective, however, it requires technical knowledge for the use and maintenance of the product.

If you want more information about any of the products, please don’t hesitate to call our sales team. Tricel remains at your entire disposal.
