Abstract:

A modification to the disinfection process, termed the 'disinfection aid process' for wastewater effluents has been investigated. The addition of a second chemical, 2,2-Dibromo-3-Netrilopropionamide (DBNPA), to supplement the primary disinfectant, chlorine, seems to be an effective method of disinfection leaving little residual and eliminating toxicity problems. Various parameters that have impacts on the disinfection-aid process were investigated.
