Ammonia Bioremediation in Poultry Waste
Specially selected microbes treat poultry processing wastewater to reduce nitrogen and organic waste levels Ammonia bioremediation prevents waste problems at poultry p[roducers. Petrox DN organisms reduced ammonia-nitrogen and BOD levels in the same wastewater reactor. The organisms in Petrox removed 40% of the ammonia-nitrogen in 48 hours. This reduction stabilized the concentrations in ...

Project - Egg washing operation
Egg washing produces a discharge with very high BOD and Nitrogen levels. Many facilities are not on public sewers and therefore require onsite treatment prior to discharge. Protection of groundwater is the primary concern. A secondary consideration is the life span of the disposal field. Walden has provided treatment plants for egg washing operations in the Northeast where winter temperatures ...

The impact of chlorine disinfection on biochemical oxygen demand levels in chemically enhanced primary treatment effluent
The response trends of biochemical oxygen demand (BOD) and organic strength after the chlorination/dechlorination process were explored through a 2-year, 5-month chemically enhanced primary treatment (CEPT) effluent onsite monitoring program and a 2-month laboratory-scale study. The monitoring results showed that better instantaneous mixing at the chlorine injection point reduced the effect of ...
