BioMEER offers B.E.D.S. (Bio-Effluent Decontamination Systems) to sterilize pathological waste water from laboratory table drains and wash-down procedures. The unique Triple Tank System by BioMEER can be supplied as a stand-alone B.E.D.S., or we can make it a ‘combo’, the Ultimate Solution to Waste Tissue and Pathological Water in a prudent Research Facility.
When using the ‘combo’ system the low BOD waste liquid discharged from a ‘dry version’ BioMEER Tissue Digester (max. 6,000 BOD) can be sent through the adjacent B.E.D.S. system to further reduce the BOD to the typical output from the BEDS. This BEDS output BOD of 200 or less, can be safely discharged to any municipal sewer system. This combo system still has capacity to accept other pathological waste water from lab drains and process.
The unique tri-tank B.E.D.S. system employs a similar mixing technology in the middle tank as is used in the BioMEER Tissue Digester systems. The decontamination process is as follows: The first tank is for accumulation and pre-heating of waste water received to 200 deg F. Once this vessel is full, the controller checks that the second tank is empty and then opens valves to allow the first tank contents drain into the second similarly sized tank. The second tank heats the water to 240 deg F for minimum 1 hour and agitates the mixture with a proprietary paddle assembly for uniform heating and energy effectiveness. This stage achieves sterilization. Then the controller checks to ensure the third tank is empty and the contents of the pressurized second tank is then transferred to the third tank which then cools the water down to 140 deg F, the safe temperature for discharge into a municipal sewer. By the time the mixture gets to this stage it also has a BOD of 200 or below.
This unique BioMEER tri-tank system provides a very energy efficient batch processing of waste water by minimizing our process vessels temperature changes, and uses the unique BioMEER vessel design and its effective heating/cooling system to do so. The heating and cooling system employs a Mokon heating and cooling unit combined with custom heating and cooling heat exchangers to circulate oil through the outer walls of the BioMEER vessel. This oil system minimizes thermal shock damage of using steam and cool water in the same vessel walls. As with the BioMEER digesters, the sources of heat can be building steam (the best choice), electricity or natural gas of a combination of these three sources. Cooling can be with re-circulating building chilled water (the best choice) or with tap water.
