Thanks to the Clean Membrane concept from Watershare, membrane fouling can be effectively managed. The concept is the product of more than 20 years’ experience in membrane fouling, particularly in the preparation of drinking and process water.
The Clean Membrane tool calculates possible scenarios of membrane fouling or damage, based on design and operational plant data. It can assist you in identifying the type and severity of membrane fouling and membrane damage, and generates suggestions for a curative or preventive strategy to control membrane fouling.
Clean Membrane benefits:
- Insights into the type and severity of membrane fouling and damage.
- An optimal strategy in combating membrane fouling and damage.
- Management of membrane fouling and damage.
- Stable operational management of membrane installations.
Clean Membrane contains a comprehensive manual on how to evaluate membrane fouling and membrane damage, and offers effective strategies to control membrane fouling or to identify membrane damage.
The manual takes into account the most important membrane fouling and membrane damage mechanisms occurring during membrane operation, and helps to determine the most appropriate membrane cleaning strategy. Clean Membrane offers both a curative and preventive approach to membrane operation, depending on the specific plant operational data input. The final outcome is a better membrane plant operation and reduced costs.
Clean Membrane determines the optimal cleaning or membrane replacement strategy as a function of the specific membrane plant data.
Clean Membrane implementation steps:
- Information collection:
completion of a questionnaire about the operational conditions of the membrane installation.
- Information processing:
the tool calculates different possible scenarios (e.g., membrane fouling, membrane damage) on the basis of critical membrane plant performance indicators.
- Results presentation:
the tool offers a problem identification and a curative or preventive strategy to control membrane fouling and/or damage.
in some scenarios, additional questions are asked, to further define the causes and consequences of fouling or damage. This might lead the tool to suggest an additional strategy.
There are several forms of support available to ensure that you optimize your use of the Clean Membrane tool, and that you are updated on all the latest developments. Specifically, you can make use of the following options to suit your particular situation:
- A short introductory course on the Clean Membrane tool for you and your clients.
- A more elaborate course, if you want to complement the tool by on-site testing or a membrane autopsy study.
- Expanded or modified Clean Membrane functionalities to create tailored solutions.
- Consultancy services, including technical process management and reporting.
- Access to Clean Membrane-related projects or research.
