looking for a Biocycle Unit?

If you’re exploring options for a biocycle unit, the Tricel Novo is a high-quality alternative worth considering. This compact wastewater treatment plant is efficient, durable, easy to install, and simple to maintain—making it ideal for both new builds and system upgrades.

Unlike traditional septic tanks, the Tricel Novo offers advanced treatment performance while remaining cost-effective and reliable. Tested to EN12566-3 standards, it ensures compliance with Irish environmental regulations and delivers consistently clean effluent.

Whether you’re replacing an existing biocycle unit or planning a new installation, the Tricel Novo provides a practical and long-lasting solution.

How does the biocycle unit by Tricel work?

Tricel Novo has a 3 stages:

Stage 1: the primary settlement chamber

On the first stage of wastewater treatment, the grease and solids are separated from the water. The grease will stay on the surface and the solids will go to the bottom of the tank.

Stage 2: the aeration chamber

In this compartment, the wastewater treatment involves aerobic breakdown. Masses of naturally occurring bacteria inhabit specially designed filter media.

The aerobic bacteria is going to digest the pollution from the wastewater. This bacteria is sustained with air, which is continuously supplied from a purpose-built pump in the unit’s top section.

Stage 3: final settlement chamber

In the third stage of wastewater treatment, the suspended sludge containing 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.

Features and Benefits of the Tricel wastewater treatment plant

  • Compression moulded SMC tank. SMC is exceptional in the wastewater treatment industry, with Tricel SMC tanks operating in some of the harshest climatic conditions for over 50 years with no defects.
  • Components are manufactured under heat and high pressure and have unparalleled strength and toughness over standard GRP tanks or PE tanks.
  • Tricel’s ceramic diffuser is a first in the domestic wastewater treatment industry 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 consistent operation and minimal maintenance and repair costs.
  • Tricel Novo plants are designed with a shallow invert to reduce both installation and time costs.

The size of your Tricel Novo unit

This is a crucial step, as choosing the correct size goes hand in hand with the overall efficiency of the treatment system. Without proper sizing, a domestic wastewater treatment system may fail to function effectively. As a result, the effluent can contaminate the local environment, leading to serious consequences such as damaged wells, polluted water sources, and broader public health issues.

How to Determine the Size of Your System?

To size a residential wastewater treatment system accurately, the most commonly used metric is the Population Equivalent (PE).

In simple terms, PE represents the load a system must handle, based on the wastewater typically produced by one person. According to the OECD, population equivalent refers to the amount of oxygen-demanding substances that, during biodegradation, consume as much oxygen as the wastewater produced by one individual.

For calculation purposes, one PE is generally considered to equal 54 grams of BOD (Biological Oxygen Demand) per 24 hours.

So, how do you calculate the PE for your home?

In most cases, the PE value is based on the number of bedrooms in the house. The more bedrooms you have, the greater the expected occupancy, and therefore, the higher the wastewater load.

To help guide you, the table below outlines the typical PE range based on bedroom count:
