WASTEWATER TREATMENT
Tertiary Treatment System
OVERVIEW
In Ireland, local authorities may specify higher effluent quality levels in specific circumstances and site assessors would recommend a tertiary treatment system based on their findings.
Tertiary treatment treats wastewater to a higher quality for discharges to surface water or for reduction of nutrients and pathogens in sensitive areas.
At Tricel, we design, manufacture and install solutions for such cases.
The tertiary treatment system generally consists of packaged filters installed after the secondary treatment plant. These systems provide additional treatment to wastewater and are ideal for homeowners, engineers, and local authorities alike.
The multiple benefits include considerably reducing the footprint of traditional percolation areas and the risk of clogged or poorly constructed underground percolation areas.
For pressurised wastewater treatment plants, Tricel offers two types of tertiary treatment systems: Tricel Tero and Tricel Sandcel.
Tricel Sandcel Sand Polishing Filter – Tertiary Treatment System
Tricel Sandcel Sand Polishing Filter uses certified sands and gravel layers with a specially designed pipework network to disperse and treat the effluent.
Ideal when…
You want peace of mind:
- It eliminates the risk of substandard non-compliant installations.
- It fully complies with planning regulations.
- A full report is provided for the client and council with all stages photographed and certification provided for components and final system.
- Maintenance schedules are available.
- All drawings and specifications are available for site assessors and planning authorities.
- A full technical backup is provided.
- You have a small site with restricted areas as it is discharged to a gravel base underneath the filter box.
Tricel Tero Packaged Filter System – Tertiary Treatment System
The Tricel TERO is a tertiary wastewater system that purifies the treated effluent from a packaged treatment plant. It has been tested for e coli treatment efficacy, is compact, easy to install & simple to maintain.
Ideal when…
- High water tables as it can be installed above ground
- Ideal for rocky ground where you can’t dig deep
- Perfect for areas where a percolation area isn’t possible due to poor ground or small areas
- Where site conditions allow, the Tero can be buried.
Pumping the effluent to the tertiary systems
Most tertiary systems get positioned above the outlet of a packaged wastewater treatment system. A pump must pump the effluent from the secondary wastewater treatment plant to the tertiary system in such cases.
Two options are possible:
- A packaged treatment plant that includes a pump for ease of installation (Tricel Novo wastewater treatment plants can have an integrated pump).
- A separate pump chamber is located after the septic tank or wastewater treatment plant.
They are both equally viable options and deliver a similar flow.
Importance of the equal distribution of effluent
Tero and Sandcel systems have been designed to accept and evenly distribute the pumped effluent from a packaged wastewater treatment plant. With this design, a low-pressure pipe network takes into account the distance and head from the secondary treatment plant while ensuring the pipe network is adequately pressurised according to the specifications. By designing the system in this way, the media are prolonged and the effluent is treated to the highest level possible before discharging from the unit.
We, at Tricel, have extensive experience with other types of dispersion systems within the Tricel product range, such as tipping buckets and gravity-fed pipe channels. In our testing, we found that these options work better when receiving gravity-fed effluent and not pumped effluent. Consequently, Tricel only offers pressurised networks for Tertiary products. Pressurised tertiary treatment systems such as the Tero and Sandcel guarantee equal effluent dispersion, which allows for better treatment quality of the effluent.

Frequently Asked Questions
WHAT IS PE ?
PE represents the initials of Population Equivalent. Population equivalent: conversion value which aims at expressing non-domestic applications in terms of domestic loading based on 1 person creates 60 g/day BOD5 and 150l/day. (Code of Practice: Wastewater Treatment and Disposal Systems Serving Single Houses (p.e. < 10), EPA)
DIFFERENT PRODUCTS SOLD BY TRICEL
Tricel Novo & Vitae
Both are wastewater treament plant solutions manufactured by Tricel. Wastewater treatment plants offer a superior quality of treatment. For example, the Tricel Novo comprises of three independent wastewater treatment zones and offers an average of efficiency of 95.9% BOD removal.
This is a higher treatment standard than the effluent from a septic tank. Please note: all wastewater treatment plants used in Ireland must comply with the EN12566-3 standard and all septic tanks must comply with the EN12566-1 standard..
Tricel Vento
The septic tank from Tricel is manufactured as a primary treatment. Designed for the settlement of your effluent. This product may need an additional treatment like the Sandcel or Puraflo.
