Klargester Biodisc

Klargester Biodisc

NOW WITH 7 YEARS WARRANTEE 

The Klargester BioDisc is the only sewage treatment plant to utilise the "Rotating Biological Contactor" (RBC) system to achieve the breaking down of pollutants plus generation of aerobic bacteria. This cost effective and adaptable solution to a range of domestic waste treatment requirements has been developed by Klargester over some 25 years.
The RBC system is designed and engineered in order to offer superior levels of reliabilty together with extremely low running costs – it is suitable for a wide range of applications.
Here are some of the many applications where the BioDisc system can be used:

  • Domestic dwellings
  • Farms
  • Pubs, Clubs & Hotels
  • Housing Estates
  • Offices
  • Industrial Estates
  • Schools, Colleges
  • Nursing & Care Homes
  • Caravan & Leisure Parks

 

We are celebrating 50 years of the Klargester Biodisc.

In honor of our celebration, we've distributed numerous Golden Tickets within the lid of our Domestic BioDisc. If you've discovered one of these Golden Tickets, simply register to stand a chance to win fantastic prizes such as holiday vouchers, shopping vouchers, and Klargester merchandise. Kindly fill out your information below to be entered into a draw for our spot prizes.

 

BioDisc has been designed to meet the British Standards Code of practice BS6297 which relates to the design of domestic sewage treatment works. Effluent treated by a BioDisc unit can be safely discharged to a watercourse but only where consent to discharge has been obtained from the relevant authority e.g. Environment Agency (EA) or Scottish Environment Protection Agency (SEPA). Here are some of the advantages of the BioDisc system:
Low energy consumption (only 50 watts).
Stable process, the BioDisc gives great performance by producing high levels of purification even under high loads.
Certified to EN12566-3 producing 95% pollution reduction - configured to produce a final effluent quality of 20 mg/l BOD5 (ATU)
Biochemical Oxygen Demand, 30 mg/l suspended solids.
Variable invert options for shallow and deep installations.
BioDisc units are composed of a series of connected reactors and chambers:
BioDisc BA-BG are self contained, single piece units.
 
BioDisc BA-BE are available with varying inlet depths to meet varying site levels.
The main structure of the BioDisc unit is made using Glass Reinforced Plastic (GRP) which makes them tough and durable. The 'business end' of the units is of course where the biological action takes place – this treatment happens on the Rotating Biological Contactor, sometimes referred to as the Rotor, in the BioDisc.This rotor is made from banks of polypropylene discs (called 'media') attached to a horizontal, zinc coated steel shaft which in turn is rotated slowly by an electric motor and gearbox.
BioDisc units benefit from low profile GRP covers, which are sectioned to facilitate easy access access. There is also a free-standing, weatherproof control panel supplied with the BioDisc unit.
 

 

So how does it work? Here is a brief description of the various stages of the BioDisc process:

 

Primary Settlement Tank (PST)
Sewage is received and heavier solids are separated and retained for periodic removal. Liquid levels in the PST fluctuate to accommodate incoming flow surges.
 
First Stage Biozone
Settled liquor moves from the PST to the first stage Biozone where it meets natural micro-organisms (biomass) which in turn colonise the surface of the polypropylene discs or media.
This first stage in the biological treatment process perfoms what is called a 'roughing stage' by absorbing fluctuations both in the Biochemical Oxygen Demand (BOD) and vitally in detergent levels which could otherwise hinder the biological action in the second stage.
BioDisc has a patented managed flow system which then transfers the liquor to Stage 2 of the Biozone at a constant rate.
 
Second Stage Biozone
Biological treatment conditions are now optimised at this stage since the liquid level is constant.
The media is now partially submerged and as it rotates, the biomass is immersed into the liquor for absorbtion and digestion of waste alternating with exposure to the atmosphere for oxygenation – since this is an 'aerobic' biological process the bacteria being used require an oxygen supply.
 
 
Final Settlement Tank (FST)
In this final stage liquor containing excess biomass forms as fine settled solids or 'humus'. This biomass enters the FST via a submerged transfer pipe. Humus is settled out and retained for periodic removal at the same time as the sludge in the PST.
