Sewage Treatment Plants
The Sewage Treatment Plants
The Tricel Novo submerged aeration sewage treatment plant is suitable for domestic and light commercial or communal applications. The plant offers its own treatment system while using simple proven fixed bed technology. Each system of the wastewater treatment plant is made of three independent treatment zones, all fulfilling three different stages of the wastewater purification process.
These highly functional plants can cater for ranges from 1 to 50 PE (Population Equivalent).
Tricel Novo products are manufactured from one of the strongest glass reinforced plastic materials available, SMC. This guarantees a very robust and durable product.
How do sewage treatment plants work?
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.
Stages of treatment in a Tricel Novo
- Wastewater enters the plant
- Primary settlement chamber
- Aeration chamber
- Final settlement chamber
- Treated effluent exits the plant

Tricel Novo wastewater treatment plant has an overall efficiency of 95.9% BOD removal.
The treatment efficiencies are as follow:
- BOD5 = 11mg/l
- SS = 16mg/l
- NH4-N = 8mg/l
Key features & benefits of sewage treatment plants
► 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 invert to reduce both installation and time costs.
► Factory fitted alarm on all systems.
► Integrated pumped outlet available on all systems.
