Field applications demonstrate capabilities of upflow biological reactors
- Celgene Corp., Warren, NJ (United States)
Biological solutions for treating hazardous and non-hazardous waste streams have existed for more than 100 years. Secondary treatment starting with the trickling filter evolved into activated sludge processes that today are used routinely to reduced organics in water streams. However, such treatment processes are limited to relatively narrow operating parameters. Temperature, pH and organic loading are only some of the operating parameters that must fall into narrow ranges to facilitate degradation. Upsets occur when parameters go outside these ranges. Two case studies are discussed where methylene chloride is successfully removed from industrial plant discharges by biodegradation. In another study, phenol and aromatics were effectively removed from industrial waste water by an in-process biotreatment system.
