OR-TEC, Incorporated products

The world`s only super fine mechanical bar screen with openings down to 1mm. The Micro Bar Screen is a superfine mechanical bar screen with openings as small as 1mm (0.03"). The Micro Bar Screen removes the vast majority of hairs, rags and stringy material which pass through screens with larger openings. These smaller openings help to prevent matting or ragging forming on items such as pumps, mechanical seals, diffusers and rotating equipment. Maintenance on these items is reduced to practically zero as ragging and matting no longer builds up.

A grit removal system which automatically adjusts based on flow. The OR-TEC Blue Micro Bar Current Grit System completely replaces a traditional headworks of a wastewater treatment plant and provides an easy to install, flange in/flange screening and grit system. Gone is the need for concrete channels for screens, concrete settling or vortex grit chambers. All that is needed to install the OR-TEC CGS is a level concrete pad and access to power and washwater. The OR-TEC CGTS Headworks is manufactured from stainless and has two distinct sections.

Quick disconnect hook up, multiple washdown points, blockage free operation. The OR-TEC Septage Receiver screens, compacts and washes screenings directly from the septage hauling vehicle. The unit is simple to install and it ensures that the septage entering the plant has been thoroughly screened. Screenings are washed, compacted and elevated to a convenient height for disposal. The Septage Receiver body is constructed of stainless steel. The screw can be constructed of stainless steel or epoxy coated hardened steel.

An efficient and affordable wastewater screen. An efficient and affordable wastewater screen. The OR-TEC Screw Screen Compactor screens, compacts, washes and lifts screenings to a convenient height for ease of disposal. The unit is provided with perforation sizes ranging from 2mm to 6 mm for municipal wastewater and 0.25mm to 2mm wedgewire for industrial applications. The unit can be mounted at an angle in a channel, in a tank or supplied for vertical installation. The shaftless design of the screw auger prevents rags or stringy material from becoming wrapped around the screw. Units are available without compactor where screening only is required. The Screw Screen Compactor body is constructed of stainless steel. The screw can also be constructed of stainless steel or epoxy coated hardened carbon steel

Perfect for Membrane Bioreactors (MBR) and the headworks of WWTP. The OR-TEC Rotary Brush screen is manufactured from stainless steel and is designed to remove fibers, hair and other foreign objects from a waste stream. It uses a static stainless steel perforated semi cylindrical screen bed for this purpose. This bed is continually cleaned by a stainless steel armature with brushes. The brushes are selected based on the particular waste and gently sweep the screen bed. This action cleans the screen bed but puts no pressure on the screen bed. This prevents the distortion and wear that can occur on other types of perforated fine screens. The brushes are cleaned by a stainless steel scraper blade and discharged outside of the machine. OR-TEC Rotary Screen brushes have approximately 1 inch of adjustment so even in situations with aggressive or abrasive wastes the brushes last many years.

Semi cylindrical bar screen perfect for the headworks of wastewater treatment plants.

A compact screen ideal where low flow, low cost screening is required. The OR-TEC LO-FLO SCREEN offers the advantage of high quality small orifice screening and compaction with the lowest capital cost on the market today. The LO-FLO is easy to install, operate and maintain. The unit comes in three sizes and can be used in applications requiring screening as small as 2mm.

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.

OR-TEC True Grit Systems are used in the separation and removal of sand and grit from the influent of wastewater treatment plants. The system features an in-ground concrete tank with mechanical mixers and paddles manufactured from stainless steel. These mixers and paddles create a vortex which settles the grit/sand. An air pump removes the settled concentrated grit to a grit classifier system where further settling and consolidation of the grit occurs. The classifier then elevates and washes the grit prior to disposal.

An inexpensive, extremely durable manual bar screen. The OR-TEC Manual Bar Screen can be provided with screen bar openings as required. Screenings are removed from the waste stream, elevated to a perforated drying deck with a manual bar screen rake specifically designed to penetrate and clean bar screen openings. The screen tank, bar rack and flanges are stainless steel. Installation is simple with flange connections provided for the influent and discharge.
