The membrane is considered the most critical component of a Membrane BioReactor (MBR). It is a type of filtration system that is used to remove pollutants, bacteria, and other contaminants from wastewater. The membrane is responsible for trapping and retaining all of the contaminants, while allowing clean, treated water to pass through. Thereby resulting in high-quality effluent.
MBR technology has become increasingly popular in recent years, owing to its superior filtration efficiency and smaller footprint, although it is often considered energy intensive and cumbersome to operate compared to conventional wastewater treatment methods.
Blue FOot's MEMBRANE
Blue Foot combines the advantages of existing systems, without their disadvantages. The Blue Foot membrane sheet is an exceptional filtration solution that consists of two PVDF ultrafiltration membrane layers which are cast directly onto either side of a 3D woven polyester textile during manufacturing. This results in an open channel within the 3D textile, the integrated permeate channel (IPC®). This channel acts as a collector for the treated water which has passed the membrane.
By mechanically anchoring the membrane layers onto the textile surface, a strong bond is created across the whole surface. This guarantees the membrane’s integrity even when under high pressure. Contrary to other polymeric flat sheet membranes the Blue Foot membrane can be backwashed very effectively at pressures up to 2 bar. This results in efficient and reliable wastewater filtration without the possibility of leakage or failure.
The membrane sheets are combined into a single module, the smallest unit in any Membrane Bioreactor. Each Blue Foot module comprises multiple sheets arranged side by side, with their equal spacing being crucial to guarantee an even flow of sludge and air along all membranes.
Overall, the unique composition and design of the Blue Foot’s membrane sheet make it an excellent choice for a wide range of wastewater treatment applications. Its mechanical strength, backwashability, and permeate channel design make it stand out from other flat sheet membranes in the market. Therefore, it has become a popular option for businesses and organizations looking for reliable and cost-effective wastewater treatment solutions.
