Reality of Membrane Cleaning Onsite
Onsite CIP systems vary significantly depending on manufacturer or system budget. RO CIP process will also vary depending on the type and degree of fouling in the RO system. This presentation will show some examples of various types of CIP systems while discussing the benefit or challenge their specific design poses. Determining foulant type and […]
Designing RO Systems for Effective Cleanings and Maintenance
Designing RO Systems for Effective Cleanings and Maintenance
Clean in Place System Design
Key features of effective clean-in-place systems used for RO will be explained. Examples showing design alternatives for clean-in-place system configuration will be presented.
Getting Back to the Basics of Cleaning – Rules of Thumb
Membrane cleaning has changed both quantitatively and qualitatively in the past 40 years but there are basic steps that should be followed. Cleaning time, temperature, hydrodynamic conditions, and concentration of cleaning agents all affect membrane-cleaning efficiency, Cleaning membranes can be costly and ineffective cleaning more so. Most membrane cleaning is done in place, generally when […]
The Importance of Data Normalization in Optimizing UF/RO Operations
A review of real-world membrane facility (UF/RO) operating data, highlighting the importance of implementing a normalization program. Raw operating data will be compared to normalized data illustrating the impact of parameters like feed temperature or conductivity. Data normalization enables daily variations in operating conditions to be accounted for so that key performance indicators can be […]
Uses of Analytical Techniques in Optimizing UF/RO Cleanings
Membrane fouling is typically multifaceted meaning cleanings can often leave non-targeted foulants behind. Matching the appropriate chemical to remove the corresponding foulant on the membrane surface is the greatest hurdle in achieving an effective cleaning. A variety of techniques exist to help identify what is fouling the system and by extension, which cleaners are best […]
Cinco MUD No. 1 Brackish Groundwater Desalination Plant
Presentation will show the challenges associated with impaired water that includes arsenic, iron, gas, boron, heat, and the membranes selected for the RO system and the pretreatment system consisting of MicroFiltration. The major plant components includes chemical addition prior to PALL MicroFiltration system as a pretreatment to the conventional brackish reverse osmosis plant . The […]
Case Studies on MBR Technologies Currently Being Implemented in Texas
Because of the historical cost and perceived complexity of MBR technology, there are still a limited number of large MBR facilities in operation in Texas (the majority of the existing facilities are package plants, less than 0.1 MGD). The goal of this presentation is to review case studies for different MBR facilities in Texas (some […]
Designing MBR Systems with Flexibility in Mind
This presentation provides an overview of membrane bioreactor (MBR) processes and identifies options for incorporating flexibility in design. Several case studies are presented that show examples of flexible MBR designs while highlighting the suitabiblity of MBR as a technology for retrofitting existing wastewater treatment facilities.
Closed Circuit Reverse Osmosis – A Dynamic, Decoupled & Data-Driven RO Solution
CCRO has emerged as the industry leader in high recovery, high reliabilty and flexible RO operation. The technology has been implemented in over a dozen industries and applications across the globe with system sizes ranging from 10 gpm to over 10 MGD. In this presentation, we’ll review the performance of three (3) of the 250+ […]
