Brim Iron Removal Media

Brim is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems.

Brim acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Brim, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of iron and produces ferric hydroxide which makes the iron combine into sediment particles and may be easily filtered.

The physical characteristics of Brim provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Brim is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods.

Other advantages of Brim include:

- long material life with relatively low attrition loss
– A wide temperature performance range and extremely high removal efficiency.

Negligible labor costs are involved because Brim does not require chemicals for regeneration, only periodic backwashing is required.
