Klargester Biotec E3


Regular price £5,230.00

The Klargester BioTec is the economical off-mains solution for single houses and uses the tried and tested aerobic biological process for the treatment of domestic sewage.

Klargester BioTec sewage treatment systems are ideal for single/multiple houses and employ the well proven aerobic biological trickling filter process for the treatment of sewage.

Easy to install, the BioTec systems are available in variety of sizes to suit any domestic application.


BioTec E1 - average house (up to 6 population)

BioTec E2 - Two houses (up to 12 population)

BioTec E3 - Three houses (up to 18 population)


The Klargester BioTec E Range sewage treatment plant uses the well-proven aerobic biological process. Treatment is a three-stage process:

  1. Coarse solids are filtered and retained for gradual breakdown
  2. The resulting liquid is continuously distributed over a plastic suspended filter by an integral lift, powered by a remotely sited blower
  3. The solids are allowed to settle and under normal domestic conditions, treated water of 20mg/l BOD, 30mg/l S.S., 20mg/l Ammonia can be achieved


The BioTec sewage treatment plant range is fully compliant, tested and approved to BS EN 12566 Part 3 and is CE marked to meet with the latest Construction Products Regulations July 2013. The BioTec is one of the products that pioneered package treatment plant technology and remains one of the most popular sewage treatment plant in the UK & Ireland.

It is ideal for locations where discharge is to sub-surface irrigation, or to a suitable watercourse (where approved by the Regulator), and where a septic tank will not meet the required standards.
