The acclaimed VORTEX™ Eco sewage treatment plant is the most advanced system in the UK and uses the least electricity for the highest treatment standard.
It is the ideal sewage treatment plant for 'ECO', sustainable and 'green' sewage treatment projects.
Much cheaper than a new septic tank and soakaway installation - the VORTEX™ sewage treatment plant can discharge straight to a ditch, stream, river, surface water drain or land drain.You don't need an expensive soakaway drainfield.
BEWARE - In-Tank septic tank conversions advertised on the internet are not accepted by the Environment Agency. They quote the BS 6297 1983 which is an outdated standard. Only the EN 12566 standard is allowed.
Unique Features of the VORTEX™ Sewage Treatment System
Outstandingly clean effluent treatment - up to 98.9% pollutant reduction
The VORTEX™ sewage treatment system recycles its own waste products for re-digestion
No Primary Settlement Tank - No Primary Tank Odour.
No need to buy a separate sampling chamber - there is a unique sampling point within the treatment tank. This saves you another £300
Simple and cheap treatment plant to maintain.
Top Quality linear motor compressor. These compressors are much more expensive than the cheaper compressors used by other treatment plant manufacturers, but they are very quiet, use very little electricity and CAN be repaired.
Performs during intermittent use (holiday lets, etc.)
Visually intrusive (large lids, kiosk, etc.)

How the VORTEX™ Sewage Treatment Plant Works
The Vortex Wastewater Treatment Plant Process
(Schematic Diagrams Only)
Wastewater from the building enters the Vibro Screen box (1). Here coarse air bubbles are used to physically break down solid matter in the sewage and form a mixed liquor with the water prior to treatment.
The mixed sewage liquor flows into the Aeration Chamber for treatment (2). A bacterial culture is present in the Aeration Chamber which digests the pollutants in the wastewater. The bacterial culture must have a constant oxygen supply and this is provided by a fine bubble diffuser at the base of the tank.
The mixed sewage liquor then flows into the Clarification Chamber (3) where it is able to separate into clear, treated effluent and sludge. The clear effluent is able to flow past the scum baffle and out of the tank.
The blower is on a plug-in timer and runs 30 minutes on and 15 minutes off, saving a lot of electricity for the treatment process. It also allows the blower to cool down. This was done on its EN Test.
The Sludge Management System (SMS)
In the Clarification Chamber sewage sludge accumulates at the bottom (settled sludge) and top (floating sludge) of the tank (1).
Air from the blower is spurred from the air regulator valves (2) to two sludge return pipes.
This creates a vacuüm that sucks the sewage sludge from the bottom of the Clarification Chamber back to the Aeration Chamber constantly (3).
The valve that removes the floating sludge must be opened once a month for this sludge to be returned. With all other ASP sewage treatment plants, this sludge has to be removed manually.
In all ASP sewage treatment plants, floating sludge accumulates at the top of the Clarification Chamber. This sludge must be periodically returned to the Aeration Chamber. If you do not want to manually open the valve on a monthly basis, then fit the Automatic FSR kit as this makes the process automatic.
The Automatic FSR Kit enables the Vortex to automatically recycle the floating sludge in the Clarification Chamber back to the Aeration Chamber.
This reduces the need for the owner to manually manage the sludge build up in the tank.
No other ASP sewage treatment plant has this ability to manage its own sludge.
The Automatic FSR Kit is an optional extra and not supplied as standard. All Vortex sewage treatment plants are manufactured assuming an Automatic FSR Kit will be fitted. The tank can be easily converted back to manual without the need to buy any other components. It is only an additional £32 plus VAT when ordered with the plant. The FSR kit can also be fitted retrospectively to existing plants very easily.
Principles of the VORTEX™ wastewater treatment plant treatment process
The Vortex™ has an advanced sludge management system not found in any other sewage treatment plant in the UK.
The ONLY electrical component is a small, external linear motor compressor which operates ALL the treatment plant process stages. There are no pumps, motors or any moving parts within the plant. It has a fail-safe alarm as standard.
Incoming sewage is screened to prevent accidental non-degradable products entering the digestion chamber. The innovative Vibro-Screen™ allows organic sewage solids to enter the tank without problems. This is an advanced feature not found on other treatment plants.
The screened sewage is aerated and a microbial 'soup' develops that digests the pollutants and organic matter in the sewage. These beneficial microbes are constantly topped up with the microbes that settle out at the bottom of the final settlement tank,as part of the sludge management system, ensuring a constant 'friendly bacteria' supply for the treatment plant process. There is no need to add extra bacteria at all, as is the case with some other treatment plants.
Benefits of the Unique Sludge Management System
When the treated sewage enters the final settlement chamber, activated sludge bacteria settle out at the bottom. These beneficial live microbes are constantly returned to the digestion chamber to mix with the raw sewage and boost the performance of the treatment plant system.
The bacterial scum or crust that forms on the top of the effluent in the clarification chamber is also able to be returned through a pipe to the digestion chamber. This is a superb innovation unique to the Vortex™. Other activated sludge sewage plants need the removal of this sludge crust and its return to the biozone,manually, by hand, at regular intervals. Click on the video below to see the VORTEX™ sludge management system in action. There are no more pumps involved - it is activated by the same small blower that aerates the plant. This saves a lot of unpleasant work for both the owner and the service engineer, resulting in lower cost servicing bills.
Settled, clean effluent in the central trough then discharges to the watercourse or soakaway. This trough is also the easy sampling point.

Superb Effluent Quality
This is the average attained during its EN 12566-3 2005 Test
Suspended Solids (mg/L)
Ammonia (NH3) (mg/L)
Well below the Environment Agency Requirement of:
Suspended Solids (mg/L)
Ammonia (NH3) (mg/L)
The above unbeatable figures enable the VORTEX™ to be installed in very sensitive areas where no other treatment system in the UK would be acceptable to the Environment Agency or SEPA.
Activated Sludge Plants (ASP's) are known to suffer when underloaded. They are either blowing the maximum amount of air, when 'on' or none when 'off'. However, the VORTEX™ sewage treatment plant has a unique air regulation valve which, by turning down the air supply valve, reduces the air supply to the diffuser. This allows the treatment plant to be 'turned down' to suit lower populations. Below are the EN 12566-3 Test Results for normal 100% flow rate and underloading at 50%.of the flow rate.
