This presentation documents membrane system design, procurement, and fabrication considerations for projects that use an original equipment manufacturer (OEM). Topics discussed include specification review, project budgeting, procurement approach, bidding schedule, and fabrication schedule. The presentation concludes with two case studies that prov...

This paper and presentation review the performance of one of the first large-scale membrane systems using Dow ultrafiltration (UF) membranes after 18 months of operation. Performance in terms of membrane integrity, permeability, log removal value (LRV) results, and cleaning requirements are reported over this period. The improvements made to redu...

Pilot testing was conducted at Sun Prairie Village County Water & Sewer District for a new water treatment plant to treat water from a local aquifer with very high hardness, sulfate, manganese and TDS. Extended testing of pressure filtration with different medias was required to provide adequate manganese removal prior to reverse osmosis. The pilot...

In the past 8-10 years, MF and UF modules have become available to system integrators from membrane manufacturers who only sell modules, much the same sales process as for the RO elements. This is a new business model compared to previously when the system integrators had their own proprietary MF/UF membranes. This non-proprietary model has resulte...

In the past 10 years, several MF and UF modules have become available to System Integrators from manufacturers who only sell MF/UF modules, much the same procurement model as for RO elements. This is a new business model compared to previously when the System Integrators had their own proprietary MF/UF membranes. The MF/UF systems using these 'non-...

There is a tendency to to design ultrafiltration systems with as high a flux as possible to minimize capital costs without being too aggressive and making operation difficult. Another approach is to design conservatively with a low design flux, resulting in a higher capital cost but a lot lower maintenance membrane system. This presentation will de...

This presentation covers the pilot study or iron removal filtration followed by reverse osmosis and the subsequent full scale system design and implementation at Prestage Foods in Eagle Grove, Iowa. This treatment system was to provide all site water requirements for the new Prestage pork processing facility. The challenges with iron removal and fo...
