Birm Iron Filter System & Fleck 2510 12 Day Timer

Description

Birm is a granular filter media system for reducing dissolved iron and manganese compounds from raw water supplies. This system includes a Fleck 2510 12-day control valve, 1-inch stainless steel bypass, 1 cu. ft. of Birm, one sleeve of gravel, and a funnel and cap. Birm acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and iron compounds, and the media is cleaned by periodic backwashing.

Birm offers an economical iron and manganese reduction method because it is not consumed during operation and does not require chemicals for regeneration. For iron removal, source water should have a pH of 6.8 or more, contain no oil or hydrogen sulfide, and have dissolved oxygen equal to at least 15% of the iron content. Birm works at maximum efficiency with pH levels of 7.2 or greater.
