Birm water filter media

stands out as an efficient and cost-effective solution for reducing dissolved iron and manganese compounds from raw water sources. Whether in gravity-fed or pressurized water treatment systems,

Birm

serves as an insoluble catalyst, facilitating the reaction between dissolved oxygen (D.O.) and iron compounds. Typically found in ferrous bicarbonate state in groundwaters due to an excess of free carbon dioxide, dissolved iron remains non-filterable. Birm's catalytic action promotes the oxidation of Fe++ to Fe+++, leading to the formation of ferric hydroxide, which precipitates and can be easily filtered. With excellent physical characteristics, Birm functions as an exceptional filter media, easily cleaned through backwashing to remove the precipitant. Notably, Birm is not depleted in the iron removal process, offering significant economic advantages over alternative methods.

In addition to economic benefits, Birm boasts a long material life with minimal attrition loss, wide temperature performance range, and exceptionally high removal efficiency. Its maintenance is hassle-free, requiring only periodic backwashing without the need for chemical regeneration. However, certain water quality criteria must be met when employing Birm for iron removal. Water should ideally be free from oil or hydrogen sulfide, with organic matter levels not exceeding 4-5 ppm. Moreover, the D.O. content should be at least 15% of the iron content, with a pH of 6.8 or higher. For influent water with pH levels below 6.8, neutralizing additives like Clack Corosex®, Calcite, or soda ash may be used prior to the Birm filter to raise the pH. Low D.O. levels in untreated water can be addressed through aeration pretreatment.

Regular monitoring of both untreated and treated water is essential to gauge the effectiveness of the filtration system. Elevated manganese concentrations in treated water pre- and post-regeneration may indicate media deterioration or bed capacity exceedance, necessitating corrective measures. Compatibility testing with Birm should be conducted before adding any chemicals to influent or backwash water, as certain chemicals may inhibit iron or manganese removal or coat the Birm media.

Clack Birm

also serves for manganese reduction with equal reliability as iron removal. Birm also known as the

best iron removal media

For optimal results, water to be treated should have a pH of 8.0-9.0. In cases where water contains both iron and manganese, a pH below 8.5 is recommended to avoid the formation of colloidal iron, which is challenging to filter out. Overall, Clack Birm offers a dependable solution for iron and manganese removal, provided water quality conditions are met.
