| dc.description.abstract | Microalgae is an industry that has been evolving a lot throughout the later years and has quite some advantages especially to the environment, from the consumption of carbon dioxide to the replacement of fossil fuel with biofuel. But, in order to produce microalgae, they need a medium to grow that needs, later, to be separated in order to obtain only the microalgae. There are several ways to separate the algae from the medium, among which are centrifugation, flocculation and sedimentation, but they have their disadvantages as they are time-consuming, uneconomic and bad for the environment. On the other hand, there is the filtration that has more advantages as being able to recover all the processed biomass, having a limited addition of chemicals and it has a low energy consumption. On this case an ultrafiltration system will be optimized for the microalgae to be harvested and passed through this system to separate them from the medium. The problem with this system is that it is a very low-pressure system, making it very hard to clean after the filtrations. The goal is to find an efficient way to clean it that is less time consuming and that allows the system to be ready to use every time an harvest is due. | pt_PT |
