Headworks Combined Screen and Grit

Or-Tec Headworks:
Replaces the entire headworks of the WWTP with screening, grit/sand and FOG removal

The Or-Tec Headworks combines two (or three machines) in one. Fitted directly at the inlet of the WWTP this unit completely pre-treats the plant influent. The unit first screens, washes and compacts the influent wastestream. It can be provided with 2mm - 6mm perforations (or 0.25 - 2mm wedgewire for industrial wastes). The screened wastestream is then treated for removal of grit & sand down to 200 microns (.007"). The grit is elevated and can be washed prior to disposal.  The unit can also be provided with an optional oil and grease (FOG) removal system which uses compressed air to aid with flotation and skimmers to remove the oil and grease for collection and disposal.

The Headworks is constructed of Stainless Steel AISI 304 or AISI 316

The screws can be constructed of AISI 304 or AISI 316 stainless steel or epoxy coated micro alloy steel
