Birm is an efficient and
economical method of removing dissolved iron and
manganese compounds from raw water supplies. It
may be either gravity fed or pressurized water
treatment systems. Birm acts as an insoluble catalyst
to enhance the reaction between dissolved oxygen
(D.O.) and the iron compounds. The physical characteristics
of Birm provide an excellent filter media which
is easily cleaned by backwashing to remove the
precipitant. Birm is not consumed in the iron
removal operation and therefore offers a tremendous
economic advantage over many other iron removal
methods.
Birm is furnished
in two grades, regular and fine. Regular is generally
recommended for industrial, municipal, and most
domestic installations. Fine is recommended on
domestic installations where backwash rates are
limited. Birm may also be used for manganese removal
with the same dependability as iron removal. |
