Abstract

The levels of amonnia and sulphide, when exceeded the critical limit became
toxic to aquatic life in brackishwater systems. An experiment was conducted in
laboratory to test the efficiency of commercially available materials viz. health
stone, BN-10 and zeolite powder in removing ammonia and sulphide from
brackishwater. Health stone + BN-10 combination was significantly (P<0.05)
superior over other treatments in decreasing ammonia (71.6%), whereas, other
treatments including bioaugmentors were not effective when applied alone.
Zeolite was not effective in brackishwater system for ammonia removal. Sulphide
removal was 100% by 3rd day with zeolite alone and health stone + BN-
10 combination
