Concentrate Management and NDPDES Permitting For Inland Brackish Water Desalination Utilizing A River Shared By Multiple States
City of Fargo North Dakota has a surface water reverse osmosis system (RO) which requires brine concentrate discharge management back to a river that meets NPDES permit requirements. Contaminants of […]
Development and Application of a Highly Reliable Silica Scaling Prediction Model for Use in Industrial Reuse RO/NF Applications with Complex Feed Waters
This paper describes a new silica scale prediction model and emphasizes the importance of considering cation species and concentrations in any membrane scaling projection. Two case studies are presented, each […]
Organic Micro-pollutants Removal in Nanofiltration Membrane Bioreactor
This presentation outlines the use of Nanofiltration to enhance the retention time of OMPs in a Sequential Batch Reactor (SBR) and the overall removal via biodegradation as well as through […]
Sustainability through Membrane System Optimization in a Beverage Facility
This paper offers a case study on a California beverage facility that set a goal to reduce their water consumption by 20%. In order to achieve that target and still […]
Reduction of high BOD and nutrient loading from fruit and vegetable wastewater with membrane bioreactor (MBR)
Membrane bioreactors (MBR) is used to reduce high BOD organics from industrial food waste streams for discharge to a municipal sewer system. Organic reduction is monitored using COD, BOD, TSS, […]
Performance of an integrated granular media – ultrafiltration membrane process for drinking water treatment
This paper presents a novel approach to reducing the problem of ultrafiltration (UF) membrane fouling. It specifically considers the application of coagulation/sedimentation pre-treatment prior to UF for drinking water supply. […]
Optimization of Conventional Surface Water Treatment for Hollow-Fiber Ultrafiltration
Surface water fed ultrafiltration (UF) membrane backwash water is frequently recycled back to the front of the system to improve system recovery. The impact of recycled membrane backwash water is […]
Impact of Clarification Step On Ultrafiltration Fouling in Drinking Water Treatment Plant
The objectives of the study were to understand the role and impact of different reagents including Powder Activated Carbon (PAC), iron chloride, and anionic polymer used in a large DWTP […]
Membrane Upgrades to Address Aging Water Treatment Infrastructure Challenges in a Small System
Deteriorating water treatment infrastructure and high levels of organics in the raw water created challenges for the Village of Hines Creek in satisfying ESRD?s more stringent treated water quality standards. […]
The RO Retrofit: Making Things Right
This paper details two retrofit case studies for systems located in the City of Toluca and the City of Macomb, Illinois, USA. A reverse osmosis system process or design retrofit […]
