Membrane Fouling – a Case Study
One of the primary operational concerns with any membrane plant is fouling. This becomes even more of a concern at higher recovery and flux rates. A case study at a […]
Application of Reverse Osmosis on a Challenging Groundwater Supplyin Central Montana
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, […]
Special Filtration Situations
The City of Cottage Grove, Oregon has a 4 mgd Pall membrane plant. Special filtration situations are created by the presence of mine wastes, fluctuating raw water flows, siltation caused […]
Operational Challenges for Membranes Treating Cold Water with High TOC Content
Raw waters with high TOC content present unique challenges to municipal treatment plant operators. These problems are exacerbated when the raw water is very cold. Plants in the Pacific Northwest […]
Retrofitting an Aging Membrane Filtration Plant
The Oden Water Association had an existing media filtration plant treating Oden Bay Water, a bay area off Lake Pend Oreille near Sand Point, Idaho. In 1999 they decided to […]
Case Study -OMND Plant in North Dakota
This presentation will discuss the operation of a 6 MGD pressurized two-stage Ultrafiltration (UF) plant over a 3 year period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility. The […]
Water Quality and Water Treatment Impacts of Watershed Forest Fires
Raw water quality after a forest fire in the watershed is highly impacted and the impacts directly affect the ability of any water treatment plant to produce potable water. Presentation […]
Design and Operation Considerations for Cold Water Membrane Treatment Facilities
Membrane facilities are becoming a common and economical form of water treatment. Special design and operational considerations must be made when using in cold climates, as their efficiencies can be […]
Permeability and Other Membrane Design Considerations
The main focus of this paper is to address several potential design pitfalls as well as other issues during construction and startup that could affect the performance and operatability of […]
Pretreatment and Membrane Effects: After the Fire?
This presentation will summarize findings of a literature search and utility survey on the effects of large wildfires on water quality, especially in regards to membrane microfiltration and pre-treatment systems. […]
