http://www.raindancewatersystems.com/commercialfilters.html 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 iron bacteria or hydrogen sulfide. If the influent water has a pH of less that 6.8, neutralizing additives such as Calcite or soda ash may be used to raise the pH. If chlorinating Birm will not remove any residual chlorine in the water. 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.
Hi tech digital 263/740i control valve. (1.0" connections standard, 3/4" available - please specify). The timer-based unit controls the backwash cycle, to assure dependability and high efficiency.

Filter Media – BIRM

Iron and Manganese removal

Supplied in 25Kg bags

What it is and how it works

Birm is a black granular filter material used for removal of iron and/or manganese from water in pressure or gravity systems.

It contains an active insoluble catalyst to precipitate iron and/or manganese. Because the presence of iron is most common, iron removal is the usual application for Birm. Under suitable conditions, the iron and dissolved oxygen in water react on contact with the Birm filter bed and, as a result, the iron is precipitated in the form of hydroxide. This is a flocculent material which is filtered out in the bed of Birm. Periodic backwashing flushes out the accumulated iron and the Birm is again ready to perform its function. Birm is not consumed in the iron removal operation.

Advantages

·         No chemicals to purchase for maintenance. Regeneration not required.

·         Iron removal efficiency is extremely high.

·         Negligible labour cost. Only periodic backwashing required once in a week.

·         Durable material with a long life. It lasts 4-7 Years according to use.

·         Wide temperature range application.

Conditions necessary for the use of Birm

Iron Removal

·         No hydrogen sulphide present.

·         Organic matter not to exceed 4-5 ppm as indicated by the oxygen consumed value.

·         Oil must not be present.

·         A dissolved oxygen content of at least 15% of the iron. (Example Iron = 10ppm. Dissolved Oxygen = 1.5 ppm or more).

·         A pH of 6.5 or higher.

Note: The correction of waters having a pH of less than 6.5 can be accomplished by several methods. Provide Aeration.

Instructions for industrial and municipal installations

·         Bed depth: 30 ­ 38 inches.

·         Standard graded gravel supporting bed depth ­14 inches or more.

·         Service flow rate: not to exceed 4 GPM per square foot.

·         Freeboard space: 35 to 50% of bed depth.

·         Backwash whenever the pressure loss through the bed increases by 2 to 3 pounds per square inch. Backwashing is usually complete within 20 to 30 minutes.

Instructions for domestic installations

·         Bed depth: approximately 24 to 30 inches.

·         Standard graded gravel-supporting bed ­ 8 inches or more.

·         Service flow rate: not to exceed 5 GPM per square foot.

·         Freeboard space: 35 to 50% of bed depth.

·         Backwashing is recommended every 7 days to 2 weeks. In treatment of high iron content waters, backwashing more frequently is desirable.If 8 gallons per minute per square foot of bed are not available for backwashing fine Birm, an air wash is recommended. This may be accomplished by drawing air through an injector into the water for backwashing.
