DSS Silkeborg AS of Denmark has launched a new microfihration membrane unit for the cheese brine clarification process used in the diary industry. The BrineClear TM unit removes impurities, bacteria and microorganisms from brining systems, which typically consist of millions of litres of water and 20% salt. The solution is used to preserve and add taste to yellow cheeses over many months, but in the process yeast, mould and bacteria can grow in the brine pool and cause surface contamination unless a filtration process is used to contain the problem. The BrineClear unit is made up of feed pumps, pressure vessels and an Alfa Laval organic spunbound membrane filter with a rating of 0.45 microns. The system, constructed in 316L stainless steel, continually filters small batches of brine to keep contaminates at an acceptable level. The cleaned brine, or permeate, is recycled and released back into the brine pool for use, while 1-2% of the batch is contaminated slurry and is thrown away in a separate waste stream. Available in three standard sizes, the BrineClear unit can be specified with a 100 m 3, 300 m 3 or 600 m 3 brine bath capacity. Larger plants can be engineered individually. The typical operating pressure is 2.5 bar. A semiautomated control system provides automatic shut-off protection, for example, if the temperature increases. Manual startup and shutdown is, however, required at the start or end of a production run to open the valves and activate the pump. Following shutdown an automated clean-in-place (CIP) process is activated to ensure that the BrineClear unit is ready for reuse.
