The VORTEX sewage treatment plant enters the UK market

Product News Wednesday, April 4, 2012: Water Technology Engineering Ltd.

WTE Ltd. are proud to have been chosen as the UK distributers for the VORTEX^TM Sewage Treatment Plant

Unique Features of the VORTEX™ ECO Sewage Treatment Plant

• Outstandingly clean effluent - up to 98.9% pollutant reduction
• Odourless - complete aerobic digestion throughout the sewage treatment plant.
• Very small footprint enables installation where space is limited.
• The VORTEX™ has a unique debris screen - tampons do not cause serious problems as with other similar sewage plants.
• Unique SLUDGE MANAGEMENT SYSTEM - enhances performance and reduces the servicing requirements and cost.
• The VORTEX™ 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 tank. This saves you another £300.
• Simple and cheap to maintain.
• Top Quality 'NITTO' linear piston compressor - these compressors are much more expensive than the cheaper diaphragm compressors used by other manufacturers, but they are almost silent, use very little electricity and CAN be repaired.
• Cheap, easy installation.
• 10 year tank warranty - no metalwork to corrode inside or outside the tank.
• Can accept sewage pumped into it if required.
• Versatile inlet depths - Vortex™ sewage treatment plants can be supplied for up to 850mm inlet invert levels.
• EN 12566-3 2005 + the much more stringent A1 2009 Certification required for FRANCE.
• Unbeatable ammonia reduction - incredibly down to 0.4mg/L. Very important for sensitive watercourses.
• Accepted by the Environment Agency for discharge to watercourses and ditches (subject to Permit)

How the VORTEX™ works

The Vortex™ has advanced activated sludge management features 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 process stages. There are no pumps, motors or any moving parts within the plant.

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. This is an advanced feature not found on other 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 digestion process. There is no need to add extra bacteria at all, as is the case with some other plants.

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 system.

The bacterial scum or crust that forms on the top of the effluent in the clarification chamber is also continually returned through a pipe to the digestion chamber. This is an innovation unique to the Vortex™. Other activated sludge plants require the removal of this sludge crust, by hand, at regular intervals.
