A Case Study of OMND UF/RO Plant in Zap, ND
The presentation will detail the case study of OMND in Zap, ND. This UF and RO system, with secondary UF, began in 2012 after a demonstration pilot in 2010 proved flux and recovery rates were sustainable. The system was then expanded in 2014 to a finished water capacity of 5.2 MGD.
Designing MF/UF Systems for Low Maintenance: 10 Year’s Experience at Two North Dakota Installations
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 […]
Wastewater vs Drinking Water Cleaning
During this presentation I will be showing some of the issues that I have encountered using wastewater in a membrane plant. I will show some of the differences between a drinking water membrane plant and a wastewater membrane plan.
Two Decades of Successful Low-Pressure Membrane Filtration of Surface Water in Tennessee – Lessons Learned
Two Decades of successful operation of the DRUC low-pressure membrane facility have demonstrated that membrane filtration is clearly a normal, not novel process that can be cost effective and extremely reliable. Optimization of the process over the first few years of operation yielded significant power and chemical savings. Fouling trends demonstrate that the membranes easily […]
Case Study: Reverse Osmosis Groundwater Treatment Expansion and Retrofit at the City of Goodyear’s Bullard Water Campus
The Well #26 and Raw Water Transmission Main project is being undertaken to provide needed capacity, redundancy and flexibility for the City of Goodyear’s water distribution system. The project scope includes a new production well (Well 26), with a targeted capacity of 1,500 gpm, transmission main and reverse osmosis (RO) improvements at the Bullard Water […]
Establishing a Baseline of Virus Removal by a Full-Scale Reverse Osmosis Sytem
Recent activity in the potable reuse field incorporates reverse osmosis (RO) processes as a requirement to provide pathogen removal and a reduction of other compounds. California has implemented the 12-10-10 log pathogen removal requirement respectively for virus, Giardia, and Cryptosporidium for proposed groundwater recharge projects. Reverse Osmosis (RO) integrity may be determined with measurements from […]

Advancements in Prediction of Risk and Establishing Plant Performance Criteria from Pathogens in Untreated Wastewater for DPR
Full Advanced Treatment for Potable Reuse in Inland Areas-Yeah it is Doable
Full advanced treatment (FAT) consisting of reverse osmosis (RO) and advanced oxidation process (AOP) has been widely used in indirect potable reuse (IPR) applications in California and some other states and is expected to be a major component of the direct potable reuse (DPR) trains in future. FAT has been proven very effective in reliably […]
