How the Klargester BioDisc® Works

Central to the operation of each Klargester BioDisc® is the Rotating Biological Contactor (RBC), which supports a biologically active film or biomass on to which aerobic micro-organisms, naturally found in sewage, become established. Natural breakdown of sewage can then occur as described below.

The Breakdown Process

Wastewater and sewage flows into the primary settlement zone (1) where solids are settled out and retained. This accumulated sludge should be drawn out periodically.

 Partially clarified liquor containing fine suspended solids flows upwards into the first stage Biozone (2) for breaking down by micro-organisms on the RBC. Suspended solids return to the primary settlement zone and the liquor is transferred to the second stage Biozone (3) for further treatment.

 Any solids remaining are settled out in the final settlement tank (4) . The very high effluent quality is discharged to a watercourse.

 The RBC comprises banks of vacuum formed polypropylene media supported by a steel shaft. This is slowly rotated by a low energy consumption electric motor and drive assembly.

 Note:The Klargester BioDisc® is designed to deal with normal domestic sewage. If the sewage is likely to contain unusual substances, please seek expert advice on 01296 633000.

Frequently asked questions

A domestic wastewater treatment plant is essentially a system that can break down sewage so that is safe enough to be released back into the watercourse. Generally, domestic sewage systems are a kinder choice to the environment, and should be considered in the first instance as your primary choice for wastewater treatment, as opposed to installing a septic tank.
There are a whole host of benefits if you decide to invest in a domestic wastewater plant. These benefits include:
  • Environmentally friendly – domestic wastewater treatment plants use natural biological processes to break down sewage and safely process harmful compounds. This reduces pollution and is vital for protecting the local flora and fauna.Preserves your drainage field, unlike a septic tank which only holds solids and therefore the treatment occurs in the drainage field, leading to a high risk of ground pollution. The risk of a failed soakaway is much higher with a septic tank.
  • Safety – untreated sewage, or old sewage systems can release hazardous materials into your local watercourses.
  • A sewage treatment plant actually treats the wastewater and you can sample it to see whether it’s working correctly.
  • A long term solution - Most modern plants also have a long life-span, and are a solid investment for any property.
  • Efficiency – the overall treatment process is efficient at breaking down sewage and there is a far lower chance of suffering annoying blockages.
Domestic wastewater treatment involves letting the wastewater settle and then using an aerobic process, to allow bacteria to break down the sewage. This process helps purify the water, allowing it to either be rerouted back into the mains sewer system, or discharged safely and sensitively into the local environment.
In the UK, any unit going into the ground may require ‘consent to discharge’ from the local Environment Agency / SEPA office, even if you are using just a storage tank. Planning permission is required from the local Building Control department.
One of the most important factors in determining the choice of sewage treatment product is the site’s drainage properties. Both septic tanks and sewage treatment plants typically require a drainage field into which they discharge effluent. Testing the ground for its permeability is usually done by professional installer using a percolation test; the correct procedure is described in BS 6297:2007. Note: your property will need to be located on highly permeable ground if you want to install a septic tank otherwise the drainage field will fail. At least half the UK sits on a clay substrate, ruling this solution out and making a sewage treatment plant the only viable option.
 
The propensity of the site to flood and the height of the water table are also important considerations. Both H2 building regulations and BS 6297 state that the water table must be at least one metre below a septic tank outlet. In this instance, and if your property is in a flood risk area, you will need to install a sewage treatment plant.
Our wastewater treatment plants are designed so that maintenance is low level, however, it’s always recommended that a service engineer checks your domestic wastewater system every year. This ensures that your treatment plant continues to work well, and future-proofs it for many years to come.
We generally recommend that you allow a professional service engineer to install your domestic wastewater treatment plant. This will allow you to feel confident that the system has been correctly hooked up to the mains sewage system or directed out to the right channels. We also have a network of Kingspan Klargester accredited installers. If you would like us to put you in touch with a local installer, contact us on klargester@kingspan.com.
You can tell if your Klargester product is fully operational by arranging for a Kingspan Service engineer to attend site under an annual service agreement.
 
We would recommend that you contact our service team in reference to this and we can advise on best course of action to give peace of mind that your unit is fully mechanically and electrically operational.
If this happens we would recommend this be actioned as quickly as possible and our service team should be contacted to arrange a site visit or a tankering. This would help address and rectify the problem with a prompt and professional turn around.
