This powerpoint presentation presents a study at the Black Brook Water Treatment Plant for
manganese removal and overcoming operational limitations through
the use of an alternative synthetic green sand media. A history of manganese treatment at the Black Brook Water Treatment Plant is provided, along with a pilot study on media selection that investigated synthetic alternatives and showed consistent manganese removal by Calgon GSR Plus Media
from 0.595 mg/L to 0.018 mg/L, a 97% reduction.
In early 2007 media replacement with Calgon GSR
Plus was completed. The backwash performance of Calgon GSR Plus is presented, along with bed expansion analysis. A summary of study results indicated that optimal filter backwashing is of great importance in
maintaining long term filter performance; and,
synthetic green sand media which can be lighter and
less dense than traditional glauconite green sand has
been shown effective in achieving an optimal
backwash at a water treatment plant with a limited
backwash rate.
Benefits include:
less costs and headaches in long run;
extends life of media;
reduces need for air wash;
longer filter runs;
better manganese removal; and, improved water quality. Includes figures.
