This powerpoint presentation presents the AwwaRF Report #3030, "Desalination Product
Water Recovery and Concentrate Volume
Minimization."
Project goal includes the following:
assess and investigate
technologies to maximize recovery
and minimize concentrate volume. Phase I included technical assessment of 22
configurations and technologies. Phase II evaluated a hybrid approach to
concentrate minimization at bench-scale. Bench scale experiments and modeling were
performed to evaluate and optimize the hybrid
approach. Four water matrices were tested to represent
different brackish groundwater types. Concentrate treatment with the hybrid
approach achieved 10% to 20% recovery
enhancement. Key assumptions were established
for the cost estimates. Costs were developed for three scenarios to
allow a meaningful comparison. Presentation conclusions indicate the following:
new paradigm in concentrate management -
concentrate minimization;
concentrate minimization makes several
disposal options more amenable;
hybrid configuration conceived and
evaluated - RO, precipitation, ED/EDR;
concentrate volume via hybrid configuration
reduced by over 70%; and,
hybrid approach is cost-competitive,
likely lifecycle cost advantage compared to
conventional RO plus brine concentrator or ZLD. Includes tables, figures.
