WHAT IS THE BASIC USE OF ZEOLITES ?
Asked by | 27 Feb, 2013, 06:14: PM
answered-by-expert Expert Answer
Pollution Control
Increases biological activity, reduces nutrient levels, cuts sludge volume and odours, reduces ammonia and BOD levels in ion exchange columns or bed effluent, can be back flushed and regenerated, with ammonia recovered for fertiliser, increases sewerage plant capacity and life cycle.
Mining
Remediation of mines through absorption and retention of dangerous heavy metals and other metallurgical wastes.
Crops/Pastures
Higher yields through making fertilisers more effective by preventing leeching and holding valuable nutrients such as ammonium nitrate, potassium, magnesium and calcium as well as trace elements for slow release as needed. Also produces long term soil improvements.
Horticulture
Retains nutrients longer to lower fertiliser costs; substantial yield improvements; less nutrient leeching; long term soil improvement.
