What is the Ecoflo biofilter?

The Ecoflo biofilter is the most sustainable wastewater treatment system on the market thanks to its 100% natural, renewable, and compostable coco filter.
This simple, compact, and energy-free solution can help you meet Irish wastewater regulations in one of two ways:
- Secondary treatment: The unit receives effluent from your septic tank and cleans it to a higher standard. Models for this use are available for 5 to 50 PE (population equivalent).
- Tertiary treatment: The unit receives effluent from another sewage treatment plant and polishes it to meet the most stringent environmental standards. Models for this use are available from 16 PE and up.
Ecoflo gives you peace of mind that you're choosing a proven and reliable solution. It is fully certified to meet EN12566-3 for secondary treatment, EN12566-6 for use after septic tanks that are in compliance with S.R. 66:2015, and EN12566-7 for tertiary treatment.
This system is ideal for:
- homes and rural holiday cottages
- singular and multiple glamping sites
- camping sites
- hotels
- golf courses and off-grid sporting facilities
- off-grid locations
Ecoflo is the sustainable septic solution
Premier Tech Water and Environment transforms coconut husk fragments into an effective filtering medium, giving new life to a valuable resource and ensuring no part of the coconut tree goes to waste.
Thanks to the organic nature of coconut husks, our all-natural filter is both renewable and fully compostable.
This makes our filter the eco-friendly solution for treating wastewater — one that continues to protect the environment even after its use.
How does the Ecoflo biofilter work?
The Ecoflo system filters wastewater through all-natural coconut husk fragments. No energy is required for treatment, making this sewage treatment plant the sustainable and economical system of choice.
Step 1: Wastewater inflow
Wastewater flows from your septic tank or secondary wastewater treatment system into the Ecoflo biofilter for additional treatment.
Step 2: Non-mechanical tipping bucket
Inside the Ecoflo biofilter, a non-mechanical tipping bucket scatters wastewater across perforated distribution plates. These plates allow wastewater to evenly trickle across the coco filter.
Step 3: Coco filter
The coco filter is the heart of the Ecoflo biofilter. It creates a physical treatment barrier that cleans effluent to an even higher standard.
Step 4: Final discharge
After percolating through the all-natural coco filter, wastewater is then discharged directly to a correctly sized stone bed or to an off-set stone bed.
