VARIABLE VELOCITY FILTER TECHNOLOGY

	Standard vessel range are manufactured from heavy guage certified 316L marine grade stainless steel.
	Specialist coatings and linings in conjuction with carbon steel vessels can be supplied for process specific applications.
	All internal components manufactured in various material combinations for relevant feed water conditions: 316 2/S - Super Duplex - PN16 rated PVC - Polypropylene
	VVF Technology is manufactured to world wide patents specific to Aqua-Sol Engineering Ltd.
	This technology enables 100% media cleaning efficiency during every backwash cycle.
	Backwash efficiency results in media replacement not being required in certain applications therefore eliminating cost of removal, disposal and replacement.
	Backwash efficiency also ensures that bacterial colonisation and bio-film & lipid build up in the media is prevented.
	Backwash efficiency ensures that flow rates are maintained within system design parameters.
	True low velocity linear flow rate through selected filtration medium.
	VVF technology allows in operation changes in throughput flow velocities without compromising filter bed definition, therefore allowing the use of inverter control for energy saving running modes and system performance variations.
	Smaller footprint required therefore reducing construction infastructure costs.
	Vessel available in split and multi layer bespoke design to therfore minimise facility downtime for refurbishment projects where restricted plant room access is an issue.
	VVF technology provides the most effective environment for the use of flocculant additives for the entrapment of chlorine resistant pathogens such as cryptosporidium.
	Our standard stainless steel vessel range can be recycled or re-used at the end of it's substantial lifecycle.
	The commercial spa Jacuzzi and Hydrotherapy range of the VVF filter has been designed specifically for the special requirements of these particular type of commercial water feature, where the performance requirement's outlined above are even more crucial for the provision of a safe filtration plant which does not encourage and support the colonisation of the filter media with opportunistic bacterial pathogens common to commercial installations of this type such as Pseudomonas aeruginosa.

Aqua-Sol VVF Filters have been widely used throughout the commercial swimming pool industry for the past 20 years and produce the highest standard of water.
