City of Clovis Expands their Membrane Water Treatment Plant to 22.5 mgd by Changing their Pretreatment Strategy and Adding Racks
The City of Clovis, CA operates a 15 mgd surface water treatment plant (SWTP) that receives its source of supply from the Kings River via the Enterprise Canal. The plant […]
Removal of Inorganic Scale from RO Membranes using Dissolved CO2
Membrane fouling is a major operational issue in reverse osmosis (RO) desalination plants. In particular, plants treating brackish groundwater can encounter troublesome inorganic membrane scales. A novel cleaning method is […]
Case Study: The Impact of Ferrous Ion Oxidation on Silica Scaling In RO Systems
A 6 MGD reverse osmosis plant in South Texas that was using chlorine to oxidize arsenic for improved membrane rejection was experiencing severe membrane fouling. The ferrous ions in the […]
Spiral-Wound Membrane Performance Monitoring for System Optimization
Spiral-wound water purification elements (e.g. reverse osmosis, nanofiltration) were developedin the 1960s in response to increasing water demand. Since then, the need for pure water has evolved to include not […]
Silt Density Index: A Fresh Perspective on an Old Index
This paper demonstrates the need for consistency in the use and selection of silt density index (SDI) filter pad chemistries by membrane treatment plant operators for their specific facility. While […]
Operations and LRV Calculations at North Dakota?s Southwest Pipeline Project OMND Water Treatment Facility
This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility. The […]
Correlation of LRV Calculation to Virus Rejection
Challenge test data from both loose ultrafiltration (UF) membranes, where the virus log removal value (LRV) is not correlated with LRV calculation model from the Membrane Filtration Guidance Manual (MFGM), […]
Maximizing Sustainability of Water Production through Split-Feed Nanofiltration Addition to Existing Multi Process Water Treatment Facility in Jupiter, Florida
The Town of Jupiter, FL decided to add nanofiltration to their existing RO/lime softening/ion exchange facilities for long term compiance and sustainability. A split feed concept was utilized to maximize […]
State Regulations and the Efficacy of Various Testing Methods for RO System Design
Normally membrane technologies are approved if they meet national and state drinking water regulations, but the flexibility and strictness of the approval process depends on the State. A key finding […]
