How Does a Domestic Sewage Treatment Plant Work?

A domestic sewage treatment plant exists to treat and clean the wastewater produced by a home. It does this using an innovative fixed bed process, wherein bacteria is deployed to grow and break down pollutants from the effluent.

The fixed bed process relies on oxygen supplied by a compressor. It uses less energy than a single lightbulb and handles wastewater treatment to environmental standards.

How does domestic sewage treatment work?

The fixed bed process is known to have excellent purification properties and also works well with load variations. This is particularly useful for things like holiday homes and bed and breakfasts, where seasonal variations are key.

These process are self-regulating. It consists of a bacterial bed and a sludge recirculation system. No matter how frequently it is used, the bacteria will break down the wastewater without degrading. Every treated effluent will always be of a sufficient quality to be discharged into a nearby stream or river.

Our domestic sewage treatment systems are high-quality and reliable with simple installation and minimal maintenance requirements. They make a great alternative to the traditional septic tank, and may actually be a better solution if your site is a good fit for one.

Domestic sewage treatment plants are more compact and require only a single treatment to be equally effective as septic tanks.

What is the fixed bed process?

A domestic sewage treatment plant consists of a number of treatment stages:

• Primary settling chamber
• Aeration
• Final settling chamber

Let’s take a closer look at each of these phases of the process.

The primary settling chamber

This is the first step of purification in a domestic sewage treatment plant. Heavy elements of effluent and sludge sink to the bottom of the tank, thus removing the major pollutants from the greywater.

Aeration

This is where oxygen is introduced into the tank. This enables the bacteria to flourish, and they go on to consume the harmful waste from the sewage.

The oxygen is injected via a small compressor which runs very efficiently. Operating costs are extremely low and it will not add much to your carbon footprint.

The final settling chamber

At this stage, residual sludge sinks to the bottom as it has a denser mass than water. This is the final stage of separating the effluent after the cleaning work the bacteria performs.

Once the final separation is complete, the water is purified to the extent required by environmental standards. This means it is ready to be removed from the tank and returned to nature.

Choosing the right system

It’s crucial to only have a high-quality, proven domestic sewage treatment plant installed. An inferior product may not perform efficiently and it might not meet the strict environmental standards required. Therefore, you should only opt for a reputable provider to supply and install your system.
