Birm is a relatively inexpensive material which can be used for iron and manganese removal by oxidation. Itrequires a pH of 7 or more for iron removal and pH 8 for manganese removal (it uses dissolved oxygen in thewater to oxidise the metal). As it acts a catalyst it is not consumed so Birm doesnt require regenerating or topping up. Birm also has the advantage of acting as a filter removing relatively high levels of turbidity. It isadvised not to use Birm in combination with chlorination and the water should be free of oil and hydrogensulphide. If the pH of the water is too low pH correction maybe required. Birm requires DO at at least 15% ofthe iron and manganese content to work.
This Birm unit is supplied partailly assembled for shipping. Some assembly will be required. All components and instructions will be supplied.
The Birm unit size is the physical size of the vessel given in inches (eg 10" x 44").
The figure in litres is the volume of the Birm.
The lph (litres per hour) figure is the maximum flow rate.
