The patented Hybrid-SAF™ biological process technology employs a submerged moving-bed, fixed-film reactor which treats wastewater with greater energy efficiency than traditional submerged aerated filters (SAFs), in a tighter site footprint whilst meeting environmental compliance.
Enhanced hydraulics for high-rate processing
Site footprint 30% smaller than comparable technologies
Energy saving timer – pulse air from the blower(s) into the process which cuts the amount of energy used to treat effluent by up to 50%
Optimising new or existing vessels of any shape and size
Scalable to accommodate growing populations
Modular off-site build overcome site restrictions and installation time
Containment vessel options - steel, concrete and GRP
Can achieve <0.4mg/l ammonia discharge
Remove phosphorus (P) with additional equipment
Can also be configured to provide anoxic conditions for Total ‘N’
Meets high treatment standards for biochemical oxygen demand (BOD), ammonia, and soluble chemical oxygen demand (COD)
No mechanical or electrical moving parts within the cells
No need to desludge the tanks or drain/remove the media during maintenance
High-level access not required for internal maintenance
Does not require additional equipment or adaptation to scour
Cells can be removed, repaired and reinstalled individually without impacting on the process and discharge standard
Patented process technology
Standardised and custom-built options
Modular cells can either operate as individual treatment plants or connected in series to form larger plants.
Can redeploy elsewhere if existing installation becomes redundant before end-of-life
Factory fitted control kiosks with blowers, panels and optional telemetry equipment
Variable speed drive blowers can deliver 50-100% of design requirements
Above or below ground installations
UK manufacture in a quality-controlled environment
Hybrid-SAF process cells offer the benefit that they can easily retrofit into any onsite existing vessel, regardless of shape or size. This saves on infrastructure costs, minimises disruptions, reduces waste and optimises site footprint. Modular containment vessels come in various materials like GRP (above and below ground), GRP with exoskeleton, steel, stainless steel and concrete.

Higher process treatment capacity is achieved within each vessel, reducing the physical footprint, which in turn optimises energy per m³ treated
The slow-moving media bed and hydraulic design ensure that the suspended solids that normally settle out are carried up and through the process to be captured in the final clarification stage
The hydraulic design ensures even and constant flows of nutrients and oxygen over the high specific surface area media, even during peak and low flow situations, providing ideal conditions for biological growth and treatment
There is no need for high-level access or lids for internal maintenance, however access can be requested to view the wastewater treatment process.
