Trickling filters with 2H media can be designed to meet stringent standards of new works. They are also utilised as a cost effective add on stage either to decrease the load as pre-treatment where the capacity of an existing works has to be increased or as a special treatment stage to meet new standards dictated by legislation.
The versatility of the 2H media range enables existing assets and treatment systems to be upgraded to meet future needs with minimum costs and disruptions to the treatment capacity.
When a company is faced with tighter discharge consents or higher industrial effluent charges, the 2H high rate filter media offers an economic, simple and reliable option to meet these demands. For the higher BOD/COD concentrations that can be experienced in industrial applications, 2H uses a combination of Cross Flow Media and Vertical Flow Media. Plus it’s really simple to operate and requires not special skills as well as being energy efficient.
Upgrading Existing Filters
One cost effective solution to increase the treatment capacity of an existing filter works is to replace the existing rock media or random media with 2H media. Due to the more open structure and high effective surface area, around 3 times the organic load, and up to 10 times the hydraulic flow, can be applied to 2H media than to rock media.
