The VORTEX Sewage Treatment Plant is an advanced activated sludge wastewater treatment system designed for domestic and commercial properties not connected to mains drainage. Featuring the innovative Vibro-Screen™ and exclusive Floating Sludge Return (FSR) technology, the VORTEX delivers exceptional treatment performance while reducing maintenance requirements and servicing costs. Engineered for reliability and energy efficiency, the system continuously recycles beneficial bacteria to optimise the treatment process, eliminating the need for chemical additives or supplementary bacteria. Its adjustable airflow control allows the plant to perform effectively even during periods of low occupancy, making it ideal for permanent residences, holiday homes, and rural properties.
With no pumps, no internal motors, and no moving parts inside the tank, the VORTEX offers low running costs, outstanding durability, and dependable long-term performance. Powered by a single low-energy external air compressor, it provides an efficient, low-maintenance solution for off-mains wastewater treatment. The VORTEX Sewage Treatment Plant combines advanced activated sludge technology, low operating costs, outstanding effluent quality, and innovative self-cleaning features to provide one of the most efficient and reliable off-mains wastewater treatment solutions available in the UK.
