icroBio Engineering Inc (MBE) has introduced their 3.4 m2 Algae Raceway®. The HDPE raceway features a center divider that is integrated seamlessly into the tank for easier cleaning. Typically, other small algae test ponds are assembled with center dividers fastened to the pond floor, which can invite unwanted bacteria to accumulate in hard-to-clean crevices. The new RW3.4 Algae Raceway reduces the time required for operators to clean the ponds after a harvest and quickly inoculate the next batch.
The raceway volume is 950 liters at 30 cm depth and comes standard in white HDPE with a UV stabilizer and uses food grade plastic, and can be custom ordered in a variety of colors.
“The number one request we get from customers is to get a paddle wheel that’s easy to clean,” says Process Engineer Braden Crowe. In response MBE redesigned their paddle wheel to be a simplified clamp-on style, 316 stainless steel, four-blade design that has almost no hardware. The design reduces corners, seams, and hardware that make it difficult and time consuming to clean. The clamp-on style allows operators to completely remove the wheel for thorough cleaning and sterilizing.
Two people can put the whole raceway together in less than 30 minutes. The tanks can now be nested to decrease shipping expenses.
The RW3.4 maintains many of the same features as the previous generation including the optional magnetic coupler between motor and paddle — an added safety feature and valuable option for universities or other educational purposes.
There is a flush 2-inch pipe fitting for complete draining, and 2-inch double-sided bulkhead for standpipes for partial harvests or continuous operation. The HDPE Stand is corrosion resistant and easy to assemble. The NEMA 4X single-phase speed controller accepts European or US standard voltages.
