Domestic Sewage Treatment Plant
Tricel Novo sewage treatment plant in details
Tricel Novo is part of the Tricel sewage treatment plant range certified to CE12566-3. It has been developed to meet a need for efficient and compact sewage treatment solutions for domestic wastewater. Indeed, the installation of a soakaway or drainage field is not always possible due to site constraints such as space (a lack of) and/or soil (clay soil, for example, might not have a sufficient soakaway potential).
Moreover, with the 2020 changes to the septic tank regulations in England and Wales, upgrades of existing septic tanks discharging directly to a watercourse are mandatory. Compact wastewater treatment plants such as the Tricel Novo represent cost-effective solutions to such upgrades.
Let’s now see how a wastewater treatment plant works and what processes are used?
How does a Tricel Novo sewage treatment plant work? The technology used
First of all, Tricel designed the Tricel Novo with a fixed culture treatment process. What is fixed culture, you may ask? It is the process used to create a base of development for the bacteria present in the tank. The bacteria multiply until they reach an optimum level for the treatment of your sewage water. To achieve this, Tricel uses a bacterial honeycomb carrier. The optimum is reached depending on the volume of wastewater to be treated by the treatment unit.
For example: for a Novo UK6, the number of bacteria in the tank will not be the same as if there are two or if you are four occupants in a house.
What happens if the number of inhabitants changes?
The number of bacteria will then adapt to best treat your wastewater (within the limits of the tank). This is particularly the case when you receive friends or family during the holidays.
The opposite is also true when the sewage treatment plant is no longer “fed” with wastewater, the number of bacteria decreases. For example, when you go on holidays for several weeks, the number of bacteria will be reduced. On your return, it is, therefore, advisable to pour into the toilet, a packet of biological activator or an old yogurt. This will help the number of bacteria to increase rapidly.
How does a sewage treatment plant work?
The Tricel Novo has three separate compartments in its tank:
Stage 1: the primary settlement chamber
In the first stage of sewage treatment, anaerobic breakdown takes place in the primary settlement chamber. The wastewater is introduced and the solids drop to the bottom, becoming separated from the liquid.
Stage 2: the aeration chamber
The next stage of the wastewater treatment involves aerobic breakdown. This takes place in the aeration chamber, where masses of naturally occurring bacteria inhabit specially designed filter media. These bacteria are sustained with air, which is continuously supplied from a purpose-built pump in the unit’s top section. As the liquid flows slowly through the filter media, the bacteria feed on the waste and remove it from the liquid.
Stage 3: final settlement chamber
In the last stage of wastewater treatment, the liquid flows from the aeration chamber into the final settlement chamber. Suspended sludge consisting of bacteria is carried with the liquid into the settlement chamber and settles to the bottom of the chamber. From there, a continuous sludge return system pumps it back to the primary settlement chamber. The remaining treated liquid now meets the required standard to be safely passed out of the Tricel system.
Once the process is complete, the treated liquid now meets the required standard and can be discharged from the tank via the outlet.
Key features & benefits
► Compression moulded SMC tank. The compression moulding process is one of the most technologically developed processes available to manufacture structural composites. Components are manufactured under heat and high pressure and have unrivalled strength and durability over standard GRP tanks or PE tanks.
► SMC is unique in the wastewater treatment industry with Tricel SMC tanks operating in some of the harshest climatic conditions for over 50 years with no defects.
► Tricel’s ceramic diffuser is unique in the domestic wastewater treatment plant market and will last twice as long as all standard competitors rubber equivalents. This saves money in both call out fees and replacement parts.
► No concrete backfill for installation on most sites saving up to €400 over lower quality grp/plastic competitors.
► No moving parts or pumps in the plant ensuring reliable operation and minimal maintenance and repair costs.
► Tricel Novo plants are designed with a shallow
