How the VORTEX Sewage Treatment Plant Works:

Incoming sewage is screened to prevent accidental non-degradable products entering the digestion chamber. The Vibro-Screen™ allows organic sewage solids to enter the tank without problems.

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, ensuring a constant supply of bacteria for the digestion process. There is no need to add extra bacteria at all, as is the case with some other plants.

The treated sewage then enters the final settlement chamber where activated sludge bacteria settle out at the bottom. These beneficial microbes are constantly returned to the aeration chamber, via the Vibro-Screen, to boost the treatment system performance.

The bacterial scum or crust that forms on the top of the effluent in the clarification chamber is returned through a pipe to the Vibro-Screen via the FSR  pipe.  This is an innovation unique to the VORTEX. Other activated sludge plants need this crust removing, by hand, at regular intervals.

It saves a lot of unpleasant work for both the owner and the service engineer, resulting in lower cost servicing bills.

Most sewage treatment plants struggle to work when they are under-loaded. A good rule of thumb is that if a system is working below 50% of its design capacity, there is not enough 'food' from the toilet solids to either grow, or maintain, a working bacterial population. VORTEX has solved this problem by having a simple hand-turned valve that can turn the amount of air required either up, or down, depending on the number of people using it. Such a SIMPLE solution to a complex problem.

VORTEX has advanced activated sludge sewage treatment plant features not found in any other treatment plant in the UK.

The ONLY electrical component is a small, external linear motor compressor which operates ALL the process stages. There are no pumps, motors or any moving parts within the plant. Click for How the VORTEX plant is so energy efficient

Description

The WTE VORTEX GRP is a compact sewage treatment plant which uses an Advanced Sludge Process (ASP) to provide an extremely clean effluent. The effluent from this plant can be discharged to a watercourse or drainage field.

The VORTEX 15 has a population equivalent of 15. This makes it an ideal treatment plant for a property with up to 13 bedrooms or a small group of 3 x 3 bedroom houses. In addition to domestic installations, this plant can be used for commercial applications.

The outstanding feature of this plant is that it can be adjusted by simply using control valves to account for lower occupancies, whilst still providing a compliant effluent discharge. In fact, the VORTEX has been tested at only 10% loading and still exceeds the national effluent standard. This makes the plant ideal for campsites, wedding venues, caravan parks and other applications where there is seasonal demand, as the process can be easily adjusted to suit.

Benefits include:

  • Fully tested and certified to EN 12566-3
  • Fully adjustable to suit the number of people using it.
  • Odourless - complete aerobic digestion throughout the sewage treatment plant
  • VORTEX has a unique debris screen - The Vibro-Screen™ keeps tampons, wipes, etc. out of the biodigester chamber of the plant, where they can cause damage, but lets organic solids through.
  • VORTEX recycles its own waste products resulting in less sludge to remove.
  • Top Quality linear motor compressor - these compressors are much more expensive than cheaper compressors used by other manufacturers, but they are almost silent, use very little electricity and CAN be repaired.
  • Cheap, easy installation.
  • 20 year tank warranty- no metalwork to corrode inside or outside the tank.
  • Can accept raw sewage pumped into it if required.
  • Versatile inlet depths - VORTEX sewage treatment plants can be supplied for different inlet invert levels - 550mm to 1,500mm.
  • Excellent ammonia reduction
