Klargester BioFicient PRO 1 - 6PE Sewage Treatment Plant
Compact, Efficient Wastewater Treatment for Smaller Properties
The Klargester BioFicient 1 PRO is the smallest model in the BioFicient PRO range, providing a compact and efficient sewage treatment solution for properties serving up to 6 people.
Designed for domestic applications where mains drainage isn't available, the BioFicient PRO 1 combines biological treatment technology with a compact footprint and flexible installation options. Its relatively small size makes it particularly well suited to individual homes, cottages, rural properties and smaller off-mains developments.
The system is supplied with a control panel, alarm and beacon, while its connectable design allows for monitoring and early fault diagnosis. A low-energy 50W blower provides the aeration required for the biological treatment process.

If you order a tank and find it is too big, too small, or unsuitable for your requirements, it can be expensive to return. Our cancellation & returns policy explains this in more detail — see Terms & Conditions.

Looking to avoid shipping charges?
All our tanks are available for collection ex works. Our suppliers are based all over the UK — please call if you wish to collect.
Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
