Powerful Landfill-Safe Absorbent
Saturated zeolites that are loaded with toxic heavy metals should be considered as eco-friendly compounds that can be landfilled. The loaded zeolite has high leaching resistance preventing easy release of the adsorbed heavy metals. In particular situations (e.g. when loaded with ammonia and phosphorus) the spent zeolite can be used as a soil amender material and slow release fertilizer. This, ...

NPDES Effluent Guidelines: A Guide to pH
In the United States, before wastewater can be discharged into a lake or river, it is mandatory to meet the National Pollutant Discharge Elimination System (NPDES) effluent guidelines. These parameters – pH (potential hydrogen), TSS (total suspended solids) and BOD (biological oxygen demand) – can be lowered by controlling algal growth. This blog is the first is a three-part series to ...
