Everblue designs, manufactures, and commercializes MBR modules for wastewater treatment since 2000. The use of MBR membrane modules in biological wastewater treatment systems allows the production of water free from suspended solids and with low concentrations of BOD and nitrogen. The water produced by MBR systems can be reused for industrial applications or irrigation.
Everblue has named its MBR module range E-CUBE, which can be supplied either with frame and connections or as a complete MBR unit consisting of the module and a dedicated tank.
Everblue MBR modules are made of Toray flat sheet membranes in PVDF (polyvinylidene fluoride) for the functional membrane layer and PET (non-woven polyester) for the base layer, providing superior mechanical strength and high chemical stability. The nominal pore size of the membrane is 0.08 microns, with a narrow pore size distribution.
Toray membranes are installed in AISI 304 stainless steel frames; AISI 316 stainless steel is also available upon request. The high quality of the stainless steel guarantees a long service life, even in highly aggressive environments.
Everblue MBR modules provide three main advantages:
- Modular design: they can meet all capacity requirements. This feature allows multiple modules to be combined to create larger configurations and to install them in a very compact layout within the MBR tank.
- Better energy efficiency: they consume less energy compared to hollow fiber membrane modules due to a more effective scouring aeration system and lower transmembrane pressure.
- Improved performance and reduced operating costs of the MBR plant: PVDF and PET flat sheet membranes provide greater mechanical resistance than hollow fiber membranes, resulting in longer service life and a significant reduction in maintenance costs. In addition, the high mechanical resistance of flat sheet membranes, combined with an efficient scouring aeration system, ensures better resistance to fouling, allowing the use of coarser and less expensive pretreatment systems and reducing overall operating costs.
