Just some of the advantages of Birm Media 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 Birm does not require chemicals for regeneration, only periodic backwashing is required.

KDF 85 media removes or reduces iron and hydrogen sulfide from your water supply.
KDF 85 water treatment media also controls bacteria, fungi, and algae
KDF 85 media removes or reduces iron and hydrogen sulfide from your water supply.KDF 85 water treatment media also controls  bacteria, fungi,scale and algae.
KDF 85 process media can remove up to 99% of water-soluble lead, mercury, nickel, chromium, and other dissolved metals.
KDF 85 media controls the buildup of bacteria, algae, fungi and scale, making it ideal for use in GAC beds, ion exchange resins, carbon block filters and inline carbon filters.
 

CAC Carbon is a catalytic, high activity granular activated carbon manufactured by steam activation of select coconut shell charcoal.

The catalytic activity of this activated carbon makes it highly effective for the removal of chloramines and hydrogen sulfide from potable water.

 

Mixture of KDF 85, Birm and Catalytic Carbon Media. 5 LBS is enough to fill a 20" Big Blue Filter

Birm® 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. Birm® acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) 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.

Birm®, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and may be easily filtered. The physical characteristics of Birm® provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant. Birm® is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods. Other advantages of Birm® 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 Birm® does not require chemicals for regeneration, only periodic backwashing is required. When using Birm® for iron removal, it is necessary that the water: contain no oil or hydrogen sulfide, organic matter not to exceed 4-5 ppm, the D.O. content equal at least 15% of the iron content with a pH of 6.8 or more.

If the influent water has a pH of less that 6.8, neutralizing additives such as Clack Corosex®, Calcite or soda ash may be used prior to the Birm® filter to raise the pH. A water having a low D.O. level may be pretreated by aeration. Additions of chemicals to influent or backwash water which contacts Birm® media may inhibit iron or manganese removal or may break down or coat Birm® media.

Chlorination greatly reduces Birm®’s activity. High concentrations of chlorine compounds may deplete the catalytic coating. Polyphosphates are known to coat Birm® and reduce Birm®’s ability to remove iron or manganese. Before adding any chemical to the influent or backwash water, the chemical's compatibility with Birm® should be thoroughly tested. Clack Birm® may also be used for manganese reduction with the same dependability as iron removal. In these applications the water to be treated should have a pH of 8.0-9.0 for best results.

If the water also contains iron, the pH should be below 8.5. High pH conditions may cause the formulation of colloidal iron which is very difficult to filter out. All other conditions remain the same for either manganese or iron removal.

 

CAC Carbon is a catalytic, high activity granular activated carbon manufactured by steam activation of select coconut shell charcoal.

The catalytic activity of this activated carbon makes it highly effective for the removal of chloramines and hydrogen sulfide from potable water.

Its large micropore volume makes it particularly well suited for the removal of low molecular weight organic compounds and their chlorinated by-products such as chloroform and other trihalomethanes (THMs).

An important feature of this material is its superior mechanical hardness and the extensive dedusting during its manufacture ensures an exceptionally clean activated carbon product.
