Evolution Meets Innovation
Innovation starts with a need. Membrane bioreactors allowed for water reuse and development, but many were poorly designed and experienced operational challenges since the early 1990’s. FibrePlate™ was born from lessons learned, derived from our pioneers who invented and commercialised the first-generation immersed membranes. More particularly, the FibrePlate was designed to address the following problems:
- Membrane sludging
- Debris accumulation
- High OPEX costs:
- High cleaning chemical costs
- High aeration costs
- Footprint matters
- Low pathogen removal
FibrePlate™ is a horizontal, hybrid 0.04 um ultrafiltration PVDF membrane. The hybrid flexible sheet membrane combines the best advantages of hollow-fibre and flat-sheet technologies into one and then innovates upon them further, delivering the most robust and reliable membrane on the market today, with operating advantages ensuring the lowest capital and operating costs available .
FibrePlate™ is an immersed membrane combing the best of Hollow Fiber and Flat Plate technologies into one hybrid, tight UF membrane. The resulting net effect is greater than the sum of its parts.
A FibrePlate module consists of (16) triple reinforced sheets, potted in a permeate header. Each module has 500 ft2 of filtration surface. The (16) membrane panels are mounted horizontally to form the only horizontal membrane in the market, which results in its open flow configuration and resistance to debris accumulation. FibrePlate’s unique header design provides unobstructed flow paths through the membrane, eliminating hydraulic restrictions, debris collection areas and ensuring 100% active surface area and low flux rates over the membranes life.
Our stainless steel cassettes are single, double or 3 module stacks and house a flexible number of FibrePlate modules that adjust to the flow needs of your plant, allowing for the “Plug-&-Play” of modules within cassette assemblies. Each cassette is designed as an integrated self-supporting unit with the ability to house from 2 to (84) membrane modules. Membrane cassette configurations are flexible and allow for the use of single, double or triple stack designs, depending on applications. All required permeate and air connections are built into the cassette frame, reducing the number of connection points and potential leaks. As the cassette is self-supporting, insertion and removal of it from a train is easily accomplished.
Our Membrane trains are flexible and go with the flow. We can configure our cassettes in typical long membrane tanks as seen in the industry or retrofit a circular clarifier. The configurations of our membrane cassettes are limitless providing flexibility and customization of design whether for new greenfield projects or the retrofitting of any existing tank.
Smaller, Safer, Stronger
Some of The Benefits of FibrePlate
Unobstructed Flow Path
A primary benefit of FibrePlate horizontal configuration is that there is no top header and that the modules and cassettes have an open flow configuration with nothing to trap debris. Without restrictions or obstruction, solids go with the flow.
The FibrePlate membrane configuration allows for a higher packing density which translates into smaller and optimal tank utilization than other types of immersed wastewater membranes. The combinations of increased packing density, increased hydraulic efficiency and not requiring “flow around” space between the cassettes and tank walls results in a significant footprint advantage compared to Plate-and-Frame and Hollow-Fiber membranes. Smaller footprint means lower civil work costs and lower capital costs as the membrane tanks can be made smaller or with capacity for future expansions.
A smaller membrane footprint means that any membrane plant can increase its current flow capacity by retrofitting existing membranes with FibrePlate. Since FibrePlate cassettes are designed to easily fit with the membrane train of other manufacturers, capacity upgrading is fast and simple. Depending on the type of membranes being replaced, Fibracast can double, triple and even quadruple plant flow.
Lower Opex Costs
The FibrePlate membranes are the only membranes that use the combined effect of aeration and mixed liquor cross filtration to continuously clean the membrane surfaces. This results in an effective continuous surface cleaning which reduces the need for chemical maintenance cleans. Using the return activated sludge flow to scour the membranes can also translate into lower energy costs since the cost to pump the RAS is lower than the cost of aeration.
FibrePlate™ for Direct and Indirect Potable Reuse Applications
The FibrePlate membrane is a tight ultrafilter with a nominal pore size smaller than 0.04 microns. This means that our membranes do not only remove Protozoa and bacteria that are much bigger than our pores, but also a large number of viruses since many viral species are larger than our pores. This makes the FibrePlate membranes particularly efficient for water reuse applications.
