Meeting the requirements of the Effluent Limitations Guidelines (ELG) means careful consideration of the various options. Both biological treatment and zero liquid discharge (ZLD) approaches have their place, but ZLD may offer more flexibility for the future. "A Comparison of ELG Compliance Options for Flue Scrubber Wastewater” by Aquatech’s Dan Bjorklund, will go into further detail on how companies are using wastewater solutions to meet these new EPA regulations. Here is an except from the article:

"On September 30, 2015, the Environmental Protection Agency (EPA) issued the final effluent limitation guidelines (ELGs) rule for steam electric power generating point sources. These regulations have major impacts on power generating facilities throughout the United States. The ELGs are technology-based regulations, which means the limitations set by the EPA under this rule are established based on best available technology economically achievable (BAT).

As a result of this rule, one of the primary challenges for coal-fired power plants is meeting new discharge requirements for flue gas desulfurization (FGD) purge streams. As such, there has been considerable discussion, study, and planning in the marketplace relative to implementation of the ELGs. The impact of the ELGs and the plan for compliance is specific to each site. There is no “one size fits all” solution."
