Birm Filters

A birm filter is an efficient and economical way to reduce iron from raw water supply coming into your home.  Birm filters are typically installed in the home before any water treatment equipment to reduce the amount of iron capable of entering the water treatment equipment. 

How does a birm filter operate?  The birm filter backwashes on a set number of days according to a water test and are sized based on the flow rate needed in the household.  When water containing iron passes through the filter bed, the active insoluble catalyst made up of the birm media causes the iron to precipitate in the form of a hydroxide. This physical particle is then retained in the media bed until the filter backwashes. Periodic backwashing flushes out the accumulated iron and the filter bed is freshened, and again ready to perform its filtration functions.

The advantages to using a birm filter:

1. No chemicals are needed for maintenance meaning the customer will save money and time by not having to purchase the chemical and the time to install the chemical in its proper place.
2. Birm is a durable material with low attrition loss alleviating expenses for the customer with replacing media regularly.
3. Negligible labor cost to operate the birm filter with only periodic backwashing

Please Note: This type of filter should not be used to remove any odor from a water supply and as with any water filtration system a complete water analysis should be performed to assure that the proper characteristics are in place for the system to work.
