This presentation will introduce the spectrum of membranes used in home, municipal, and industrial applications. The membranes types will be reverse osmosis, nanofiltration, ultrafiltration, microfiltration, and membrane bioreactors. We will highlight the attributes of each membrane type ranging from what is rejected to the pressures required to ac...

This paper will present the basic considerations for setting up a pilot testing protocol for membrane applications on both groundwater and surface water. A description of the types of pilot units to be considered will be provided. Data on several mid-west pilot case studies will be presented....

This 30 minute presentation will discusses the most effective procedures for membrane cleaning, and explains the role of high pH and low pH cleaning chemicals. As well as the value of normalized data...

The end cap assembly is a critical component within the pressure vessel. Properly maintained and secured end caps reduce safety risks and concerns and ensure that the pressure vessel can continue to operate at full capacity with limited operational downtime. Instituting inspection and preventative maintenance of the end cap assembly will limit fluc...

Lancaster's Upper Hocking WPCF is a novel membrane bioreactor treatment facility with a current rated capacity of 2 MGD and detailed design underway on an additional 2-MGD expansion. Following influent fine screening and biological treatment in a series of vertical loop reactors, mixed liquor enters one of three membrane tanks equipped with 0.1-mic...

This paper will provide an overview of the City of Lancaster's South Water Treatment Plant. A description of the raw and finished water quality goals, high-level design criteria for each of the unit processes, unique features of the plant, and planned upgrades will be presented....
