Surface water fed ultrafiltration (UF) membrane backwash water is frequently recycled back to the front of the system to improve system recovery. The impact of recycled membrane backwash water is addressed and how to mitigate fouling of the UF....

The town of Jupiter operates a unique nanofiltration (NF) plant that includes an innovative system of split-feed pressure vessels configured with center-port concentrate outlets. When the plant was designed, the split-feed concept was considered a promising design innovation to reduce feed pressure. Now, with seven years of successful operation and...

Today?s industrial reuse challenges require innovative solutions. This presentation will share the successful planning and design of an innovative tertiary membrane bioreactor (TMBR) facility. This facility will provide flexibility to meet future water quality challenges, reduce costs to enable water reuse while preserving potable water, and manage...

This paper discusses results of an extensive pilot study conducted for City of Dunedin to evaluate pretreatment options for treating groundwater containing Fe and Mn with RO. Processes tested include several oxidants (Cl2, ClO2, O3, KMnO4 and combinations of some of them), 3 types of media (sand, greensand plus, pyrolusite), two UFs (ceramic and po...

This paper will discuss an emerging approach to developing holistic data management tools for membrane systems. Several case studies will be presented which will demonstrate to operators, engineers, and management staff how dashboards and modern data analytical innovation can address a variety of challenges and inspire proactive operations....
