Installation of a SAF™ System for Pre-Treatment of Municipal Wastewater Effluent for Title 22 Unrestricted Wastewater Reclamation / Tertiary Filtration
(Click image to enlarge)
Heron Innovators manufactures Suspended Air® Flotation (SAF™) systems for removal of suspended solids from wastewater. SAF™ solutions are backed up by years of process knowledge and manufacturing ability. This particular project required the removal of specific components - algae and colloidal material - from the pond effluent. The goal was to extend filter cycle times, and achieve <9NTU water clarity prior to filtration for unrestricted reuse of wastewater.
The Model SAF250 system supplied by Heron Innovators was fabricated from stainless steel using various precision fabrication methods. The dual compartment conditioning tank, the tallest component within the system, measures 8 ft. diameter x approximately 10 ft. high and has a 3,500 gallon capacity. Also supplied were a Model CF250 ClearFloater™ flotation tank and two Model F50 froth generators, one serving as an installed spare. Prior to installation, a pilot test was conducted by the project engineer using a Heron Innovators complete treatment system on a trailer. As performed on all Heron Innovators systems complete functional testing was completed prior to delivery of the equipment, in this case the pilot trailer, to the site. Following the successful pilot test, a public agency single-sourced the system based on the test results. This SAF™ system is fully integrated with the customer's SCADA system.
