Though there has been rapid growth in the low-pressure membrane market for drinking water
treatment, the application of this technology to large water utilities has been limited. Hydraulic
and water quality performance data gathered during a six-month pilot study in Kansas City has
demonstrated that retrofitting granular media filters with low-pressure membranes in large plants
can be an important tool to meet ever-increasing regulatory requirements while substantially
increasing plant capacity.
The overall objective of this project was to identify and examine the key issues related to
retrofitting existing granular media filters with membrane media filters in large water utilities. There were several specific objectives to the project.
The first was to
develop full-scale membrane system design for retrofitting the Kansas City Water Services
Department (KCWSD) water treatment plant with membranes selected for specific
characteristics that make them well suited for the application. These characteristics include
high permeability, high fiber packing density, and chemical compatibility.
The second specific objective was to develop conceptual layouts detailing both gravity-fed and pumped membrane retrofit
scenarios at KCWSD based on the design parameters developed during pilot testing. This
exercise included an analysis of integration issues such as the use of existing infrastructure, ancillary equipment requirements, membrane integrity testing protocols, and operator
training requirements. The third specific objective was to
develop cost estimates for retrofitting existing granular media filters with membrane media
filters at the KCWSD water treatment plant. Discussion of the approach used includes testing site, membranes tested, and testing protocol. Includes tables, figures.
