Birm media

Birm represents a highly effective and cost-efficient solution for the extraction of iron and manganese compounds from untreated water sources. It is applicable in both gravity-fed and pressurized water treatment systems.

Acting as an insoluble catalyst, Birm facilitates the interaction between dissolved oxygen and iron compounds. In groundwater, iron typically exists in the ferrous bicarbonate form due to elevated levels of free carbon dioxide, rendering it non-filterable.

Birm catalyzes the oxidation of soluble iron compounds, converting Fe++ to Fe+++ and resulting in the formation of ferric hydroxide, which subsequently precipitates and can be easily filtered out. The material can be efficiently cleaned through backwashing to eliminate the ferric hydroxide. Importantly, Birm is not consumed during the iron removal process, offering a significant economic benefit compared to various other iron removal media.

Additional advantages of Birm include its extended lifespan, minimal attrition loss, a broad operational temperature range, and exceptionally high removal efficiency. Under optimal water conditions, it does not necessitate the use of chemicals for maintenance, and regeneration is unnecessary. Birm is also effective in reducing manganese levels; for optimal results, the pH of the water should be maintained between 8.0 and 9.0. When both manganese and iron removal is required, the pH should be kept below 8.5.

ADVANTAGES:

• Under suitable conditions, there is no need to purchase chemicals for maintenance, and regeneration is not required.
• The efficiency of iron removal is exceptionally high.
• Labor costs are minimal, requiring only periodic backwashing.
• The material is durable, with a long lifespan and a wide temperature performance range.
