Comparative Capiltal Costs for Ceramic and Polymeric Membranes
Ceramic Microfiltration (MF) membranes are compared cost wise to polymer based MF and ultratfiltration (UF). Present Worth Cost of 20-years show comparable long term costs. Ceramic membranes are said to be more robust, have higher pressure ratings, and chemical resistance when compared to polymer membranes....
Novel Segmented Ceramic Monolith Ultrafiltration Membrane Provides Improved Pre-Treatment For Power Plant Cooling Tower Blowdown ZLD System
This presentation will describe the pilot testing results used and the conceptual design and operating cost estimates of the full-scale upgrade of the Cooling Tower Blowdown (CTBD) treatment plant, which benefits from the use of ultrafiltration ceramic membrane used in the process....
Hydraulic Cleaning Methods for Ceramic Membranes - A More Conventional Approach to Facilitate Retrofits
This paper will present hydraulic cleaning design summary options for ceramic and polymeric low pressure membranes as well as field testing data comparing more conventional to more aggressive methods. The paper also presents some retrofit case histories where ceramic has replaced polymeric membranes....
Data And Economic Analysis of Ceramic Ultrafilter Membranes In Backwash Water Recovery and Waste Water Reuse Applications
With the latest advances in ceramic ultrafiltration (UF) membrane manufacturing the capital costs are now competitive to polymeric UF membranes. The presentation will review performance data of the latest ceramic UF membranes in installations and pilot trials treating backwash water recovery and secondary effluent for reuse. The data highlights th...
High-Turbidity Backwash Waste Recovery for Potable Use at Surface Water Treatment Plant
A common complaint for water treatment operators when it comes to hollow-fiber MF/UF systems is the frequent repairs and production downtime needed for fiber breakage issues. At a Midwestern surface water treatment plant, treating backwash waste (variable turbidity) from the primary MF skid to increase recovery for potable water production is neede...
Ceramic Membrane Retrofit of Polymeric Hollow Fiber Systems
Nanostone Water has sucessfully retrofit a number of polymeric MF and UF water treatment plants with its CM-151 ceramic ultrafiltration module. The CM-151 was designed to be easily mounted on existing racks with minimal plant downtime and modifications....
Ceramic UF Retrofit of Existing Polymeric MF at Surface Water Treatment Plant: Retrofit and Commissioning Experience
Nanostone Water ceramic UF retrofit of polymeric MF at a drinking water plant in SD, USA. This paper discusses the retrofit experience and methodology and also compares performance of the ceramic UF to the primary MF system at the same location, running side-by-side....
Ceramic Membranes on the Boise River
This presentation discusses the advantages of ceramic (CM) ultrafiltration membranes (UF) for surface water treatment for municipal drinking water applications. Nanostone piloted their ceramic membrane technology for 2 years on the Boise River, and has been retrofitting other polyeric membrane plants in the last few years. This presentation will di...
Effectiveness of Ceramic Ultrafiltration for SWRO Pre-Treatment
Desalination is becoming vital for securing a strategic and sustainable source of water around the world, and membrane-based seawater reverse osmosis (SWRO) desalination is a popular desalination technology. An effective pre-treatment process for SWRO impacts the performance and costs of the overall plant. Pre-treatment processes for SWRO are eithe...
Upgrading a Drinking Water Membrane Plant with Ceramic Membranes
Membrane treatment plants represent efficient and effective means of treating various source waters. Microfiltration (MF) and ultrafiltration (UF) membranes are capable of removing particulate, bacteria and some viruses. When membrane plants run well, water quality is consistent, production capacity is dependable, and consumers can count on water t...
The Effectiveness of Ceramic Ultrafiltration as a Pre-Treatment for SWRO at TUAS Spring Singapore
SWRO pre-treatment with polymeric MF/UF membranes initially gained a wider acceptance mainly due to its reported superior removal of particulate and colloidal foulants (absolute filtration), low footprint and its benefits in terms of consistent and reliable performance, and operational flexibility. It was hoped that this approach would also solve p...
