Tennessee has historically and consistently been a leader in the adoption and use of microfiltration and ultrafiltration for surface water treatment. Continuing with that legacy, multiple case studies are shared where Tennessee continues to take the lead on new technologies. SiC Ceramic Ultrafiltration was piloted on varying and complex surface waters, where existing treatment systems ranged from conventional treatment to polymeric membranes. Ovivo, in collaboration with multiple engineering firms, has piloted SiC ceramic membranes at six Tennessee utilities in the past year. The driving need for membranes at these utilities has ranged from water quality changes, increase in water demands, expansion into a limited footprint, and a desire to eliminate replacement of consumable polymeric membranes. One utility is currently a 4 MGD surface water plant with a need to expand to a total capacity of 7 MGD. With a newly occurring algae bloom the past two years on their source water, the utility and the engineer investigated the use of SiC in combination with PAC (powder activated carbon) to tackle taste and odor issues. Over the course of a 3 month pilot, finished water quality was improved over existing conventional multimedia gravity filters, and now the expansion will move forward with ceramic membranes for filtration. Another utility has a conventional water treatment plant with a capacity of 20 MGD. With a reliably consistent surface water source, a 2 month pilot here investigated flux, TMP, turbidity and TOC removal with positive results. Other sites investigated replacing or retrofitting existing gravity filters with ceramic membranes due to space constraints on their site. In addition, utilities with polymeric membrane installations are piloting ceramic membranes for performance improvements, capacity increases or eliminate the need to regularly replace membranes as their recoverability declines. Evaluations for these piloted projects have covered: SiC robustness, flux rate, raw water characteristics, chemical conditioning, water temperature, cleaning chemicals, turbidity and TSS reduction and more. Utilities and engineers are using pilot testing to assist with critical decision making for system upgrades or expansions. Whether the plan is to replace aged gravity filters, replace worn out membranes, or install a new water treatment plant, piloting has provided helpful full scale design plans and operation insight.
