Microdyn-Nadir (Wiesbaden, Germany; (www.microdyn-nadir.com) has signed an agreement with its U.S.-based partner, OVIVO Water, to start the construction of its second Bio-Cel production line in the U.S. Microdyn-Nadir decided to build its second Bio-Cel production line in the U.S. following the globally growing demand for membrane bioreactor (MBR) technology. Construction works will start soon and the start of operation is scheduled for the beginning of 2017.
By means of the second Bio-Cel production line Microdyn-Nadir is confident to be able to react even faster to the market needs. “Local market presence is key to being a meaningful player in the U.S.”, says Walter Lamparter, CEO at Microdyn-Nadir Group. “With our second Bio-Cel line, we will be able to minimize freight costs and realize shorter delivery times and it allows for more flexibility for the fast turnaround of large quantity orders world wide. Together with our local U.S. partner OVIVO Water we offer decades of experience in MBR technology.”
Microdyn-Nadir, with five locations globally, focuses on the production and distribution of membranes and membrane modules and is a leading global supplier of membranes and modules for the micro-, ultra- and nanofiltration market.
In 2005, the Bio-Cel was initially introduced to the market with a membrane area of 10 and 50 m² per module. Since then, several larger module types have followed – the Bio-Cel BC 100 (100 m²), the Bio-Cel BC 416 (416 m²) and the Bio-Cel XL with a total membrane area of 1,920 m2 which is especially suitable for large-scale wastewater treatment plants.
The Bio-Cel is a submerged MBR module for wastewater treatment and combines the best of two technologies – the plate and frame configurations as well as hollow fiber modules. It is based on flat membrane technology. Two membranes are laminated onto both sides of a drainage layer. The Bio-Cel membrane laminate sheets are integrated into the membrane stacks in a unique way so they can move gently with the crossflow. Due to their unique “hollow sheet structure” they are very stable and robust — even after potential damage of the membrane the “selfhealing mechanism” of the Bio-Cel laminate will ensure high permeate qualities. Besides, the Bio-Cel is unsusceptible to braiding and sludge deposition and is backwashable. The MCP — the Mechanical Cleaning Process for the Bio-Cel MBR— not only enables the continuous cleaning of the membrane and therefore constant high permeability of the membrane but also allows for a tremendous reduction in chemical usage.
