Why is using ultrafiltration technology more efficient than conventional wastewater treatment?
Mokbel: If we take the example of a sedimentation tank (or clarifier), this requires a very high residence time in order to allow the contaminants to coagulate and precipitate at the bottom of the tank. Ultrafiltration, on the other hand, does not require any residence time. We don’t need to wait for the pollutants to coagulate, as the membrane takes care of separating them. So it’s a lot more efficient because the process is continuous and it doesn’t require a lot of space. This type of equipment is modular, so if a client needs a greater capacity, we simply need to add more modules without the necesity of more civil works. The equipment can be adjusted to treat a certain amount in a first stage, with the ability to treat a greater amount in the future. For example, if we need to double the capacity, it’s very easy to install a second unit, without the need for heavy construction. If we use conventional plants for potable water treatment, for example, if we wanted to double the capaci
