The Roberts Filter Group - WW Block - Tertiary Filtration System

TERTIARY FILTER SYSTEMS

DEEP BED FILTRATION

The Roberts Deep Bed Filtration System is based on a combination of established technology as well as the latest developments in filter design. 6 foot media bed depths of relatively large media allow for a high solids retention capacity and great flexibility in filter operation. Extended filter run times at high loading rates are the norm.

Proven through over 100 years of experience, the Roberts’ system features a simultaneous air and water wash of the filter media which provides a very thorough cleaning of the media bed.

Roberts utilizes the latest technologies in filter control, underdrain and air scour design to optimize deep bed filter backwash and operation. A variety of options are available to provide the right solution for any application.

DENITRIFICATION
Fixed Film Biological Process

Combining fixed film biological denitrification with deep bed tertiary filtration.

The deep bed media configuration serves as both an excellent means of removing suspended solids, and as a perfect environment for denitrifying organisms.

The use of coarse monomedia optimizes the surface area contact with the wastewater while still minimizing headloss build-up. Dual and mixed media configurations are also available.

The Nitrogen gas which accumulates in the filter bed is removed through time-tested methodologies. Conventional air/water backwash is utilized to remove entrapped particles from the filter bed. Backwash cycles are initiated on time and headloss.

Existing tertiary filters can be converted to denitrification through the introduction of a carbon source and the addition of the ARIES^® Managed Air Scour System
