@Cassie Ann Hoffman Yes, you have raised my primary design problem which is how to meet different models and specifications in different companies and countries.
Well, the way I see it, I have two options.
1. Make some kind of arrangement with major washing machine manufacturers and make the dive assembled in every product that will be sold in the future.
2. Build different model based on the different output of wastewater which contains the micro fibres.
That is why I am working to get the attention of washer manufacturing companies by publishing the innovation in different sites like https://contest.techbriefs.com/2019/entries/electronics-sensors-iot/9471 or https://contest.techbriefs.com/profile?user=89682
Yes, I am familiar with Cora ball method but with full confidence, it is not as effective as this mechanism capturing all the microfibers in a single wash because as you know there can be minimum of 700,000 tiny microfibres in a single wash. This mechanism can sort microfiber 100%.
