Membrane Basics
The presenation will be aimed at individuals that are not familiar with membrane basics and terminology. Basic priniciles of reverse osmosis, ultrafiltration, microfitration, nanofiltration will be reviewed with an emphais on how they function and differ. A short review of the different membrane module and element construction will be given alo...
GWRS - The World's Largest Indirect Potable Reuse Facility
The Orange County Water District's (OCWD) Groundwater Replenishment System (GWRS) is a 100 mgd indirect potable reuse facility located in Fountain Valley, California. This facility has been in operation since 2008 and was recently expanded from 70 mgd to 100 mgd after a three year construction project completed in June 2015. This facility treats ...
Dealing with the Past, Managing the Present and Planning for the Future
his presentation will discuss the lessons learned by West Basin from 20 years of membrane application, discuss West Basin?s current effort to catch up and implement several industry standards, and share how West Basin plans for its future water reliability and expansion. Specifically, the presentation will review West Basin?s past designs, construc...
Checking In on the Chino Concentrate Reduction Facility
The Chino Basin Desalter Authority (CDA) is a Joint Powers Authority consisting of eight members and owns the Chino Desalters (I and II). The Chino II desalter began operation in 2006 with a capacity of 10 mgd, and was expanded to 20.5 mgd in 2011. High brine disposal costs, brine line plugging, and the availability of construction-related grand fu...
Tractor Paint Factory Wastewater Recycle Stream with Kubota MBR
A tractor manufacturing factory is very similar to an automobile manufacturing factory, both using significant amounts of water for the pre-paint washing process. Before the tractor parts are painted, they are washed in several steps to remove dust and oils, and to provide surface coating. The wastewater from each step has different characteristics...
Integrating Membrane Filtration with Existing Slow Sand Filters
n 1999 North Clackamas went on line with 10 MGD slow sand filtration. In 2005 10 MGD of submerged membrane filtration was added to increase capacity and to help when high raw turbidity occurs. This presentation will cover how the two very different processes compliment each others strengths and weaknesses....
La Center Wastewater Plant Overview
The City fo La Center is a Membrane Bioreactor Wastewater Treatment Plant with bilogical nutrient removal. The presentation will be a brief history and overview of the plant prior to a tour of the facility. Discussion about the type of equipment and the operation of the facility ove r the 6 year period the plant has been in operation....
Challenges and Benefits of Conventional Activated Sludge/MBR Parallel Operation
My speech will be about the challenges and obstacles of operating an MBR plant parallel to an activated sludge plant. I'll describe what we have done to overcome these obstacles and how the MBR plant is such an asset to us from a capacity standpoint as well as a regulatory standpoint....
A Year in the Life of an MBR Plant
The City of Hermiston installed an Membrane Bioreactor in 2014 to replace an existing RBC plant. The plant has been operating for over a year now with good results. The challenges associated with startup of a new membrane plant will be discussed. Other topics include the reasons for the upgrade to an MBR system, operation of the existing plant d...
Startup/Testing and Operational Challenges of JBLM?s Low Pressure Membrane System
This session will discuss the process layout, design, performance parameters, and operating procedures of the army base, Joint Base Lewis-McChord's wastewater membrane filtration treatment of secondary effluent. We will discuss the startup and testing of the system in the context of the entire plant startup and testing. And will touch on alternativ...
MBR and the 3 Rs
With over 600 permitted installations in the United States treating upwards of 1 billion gallons per day (BGD), membrane bioreactors (MBRs) are playing an increasingly vital role in water conservation. While many new wastewater treatment plants (WWTPs) are constructed every year, the majority of MBR projects involve the 3 Rs; water reuse, the retr...
The Use of Flat Plate PVDF MBR Modules for Sludge Thickening
Flat Plate MBR membrane modules can be used for thickening waste activated sludge from conventional treatment plants or from MBR waste water treatment plants reducing the cost of sludge handling and increasing the volume of water available for reuse....
Improving Organic Reduction and Overcoming Challenges at an MBR Plant Treating Wastewater from a Polyester Production Process
When a prominent plastics manufacturer encountered issues with settleability and organics reduction in their wastewater plant's secondary treatment system, they consulted several membrane system providers to determine the feasilbility of using a membrane bioreactor (MBR) to solve the problems. They narrowed the field to two manufacturers, and had ...
Failure Testing As A Startup Tool For Membrane Filtration Plants
This presentation summarizes the startup testing methodology that the author has used on 6 microfiltration membrane municipal water plant startups performed in the last 4 years. I will discuss a different approach to testing that provides great benefits to the owner. This presentation explains a testing and checkout process that contrasts to the ty...
On-Demand Gravity Powered Ceramic Filtration Facility: A New Philosophy in Montana
A new filtration water treatment plant (WTP) is required for Basin Creek water in Butte-Silver Bow, MT. The Big Hole water plant struggles to remove an unusually large organic color load during spring, and ecological conditions are making this problem even worse. The Butte-Silver Bow (BSB) water system challenges have DEQ?s attention and BSB will...
Phasing and Pretreatment Considerations for Clifton Water District?s Media Filter to Membrane Filter Conversion
In 2015 the Clifton Water District completed a project to convert the its 34 year old, shallow bed media filters at its drinking water treatment plant to a more robust and reliable membrane filtration system. The conversion took place without interrupting water service to its customers over the 10 month period between ground breaking and the membra...
Hybrid Membrane Processes: Shaping the Future of Drinking Water Treatment
Over tle last 7 years, a large research program has been initaed at Polytechnique Montreal to develop novel hybrid membrane processes (HMP) which combine high concentration PAC reactors with low poressure membranes. The conference will aim to summarize (i) the need for the devlopment of HMP for the water industry, (ii) the potential configurations ...
Keeping Membrane at It's Optimum Operating Conditions
Since the first wave of adaptation of membranes in drinking water industry in early 1990?s, thousands of membrane plants have been constructed around the world.
