| Abstract | The research program included laboratory process development of a unique physical-chemical wastewater treatment process followed by design, construction, and field demonstration of a 100,000 gpd mobile pilot plant. In the treatment process, raw wastewater is contacted with powdered carbon, coagulated with alum, settled with polyelectrolyte addition and, in some cases, passed through a tri-media filter. The program demonstrated the ability of the treatment process to consistently produce high-quality effluent from raw wastewater. Powdered carbon regeneration was highly successful on the pilot scale. Full capacity recovery was achieved with less than two percent carbon loss per regeneration cycle. Alum recovery was also greater than ninety percent. (Author Modified Abstract) |
