Established Practices, Innovative Design, and New Products: A New Generation of Ultra High Pressure Desalination
In common parlance, reverse osmosis (RO) is often described as removing salt from water. In practice however, these processes squeeze water from a salt solution resulting in concentrate to be […]
A Novel Method for Modeling Brine and Permeate pH in RO and NF Systems
Concentrate pH in RO and NF applications plays a significant role in the formation of certain scales and the rejection of various contaminants. Incorrectly predicting pH can lead to excessive […]
Evaluation of an Integrated Tertiary Treatment System for Ultra-Low Level Phosphorus Removal in Hayden, Idaho
The Hayden Wastewater Treatment Plant process consists of a headworks, equalization, enhanced biological nutrient removal, oxidation ditches, and secondary clarifiers. The facility produces typical effluent total phosphorus (TP) concentrations in […]
Filtration with Inside-to-Out Ultrafiltration Membranes of Wastewater Containing Powdered Actgivated Carbon
This study presents and compares results obtained with inside-to-out polyethersulfone ultrafiltration membranes operated on three different wastewater streams in two locations. The first stream tested originated from a wastewater containing […]
