Waste Water Desalination in Pulse Flow Regime
The standard waste water RO desalination technology based on two or three stages RO train arrangement. Standard Process include chloramine dosing to prevent bio-fouling, and antiscalant addition to prevent scaling […]
Fully Carbon Membrane for Wastewater Reclamation
We demonstrated the fabrication of a polymer-free and fully carbon membrane (FCM) to be used for water treatment. A FCM combines the advantageous properties of polymer and ceramic membranes and […]
Analysis and Removal of Contaminants of Emerging Concerns from WWTP Primary Effluent by Novel MF/RO Treatment Process Pilot Study
Cal Poly Pomona, Carollo Engineers, Inc., and Pall Corp. are participating in a water reuse research funded by Bureau of Reclamation to evaluate novel treatment train ?integrated membrane anaerobic stabilization […]
Membrane Activity for Water Treatment in North America
Pilot Testing of Nanofiltration To Minimize TOC Levels and DBP Formation
The presentation describes the pilot testing arrangement with an infiltration supply well, ultrafiltration pre-treatment system and three stages of NF membranes to simulate full scale operation to reduce TOC to […]
Potable Water Production: Different Membrane Technologies for Organics Removal from Surface Water
This abstract compares two different membrane technologies: low pressure membranes and a newly developed hollow fiber nanofiltration membrane. The ultrafiltration plants in Scandinaviaemploy a unique method of integrity testing that […]
The Causes and Cleaning Strategies for Microfiltration Membranes Fouled by Iron
Membrane fouling caused by iron or the combination of iron and organic matter is very common operating issue in membrane plants. Iron species in natural water can be dissolved, via […]
Is Organic Fouling Making Your Life Difficult? Mitigation of Organic Fouling of Low Pressure Membranes Using LC-OCD
This paper will describe the use of a unique organics characterization method, liquid chromatography with on-line carbon detection to identify the primary cause of organic fouling in two fouling scale […]
Removal of Colloidal Particles through Online Monitoring to Lower Microfiltration Membrane Fouling
Fouling of microfiltration (MF) membranes results in increased energy demand, increased cleaning intervals, and membrane replacement frequency. MF membrane fouling is largely due to deposition of colloidal nanoparticles
A Better Place to Be in than Utopia: Successful Reuse Facility Design Using Multi-Objective Optimization
This paper presents a successful story for optimizing the design of an industrial reuse facility using MF/RO/UV. Design parameters were established based on pilot testing and engineering evaluation. However, the […]
