The invention relates to a waste gas system for bioreactors having a hydrophobic sterile filter, arranged at the end, and a heat exchanger which protects the sterile filter against blocking by liquid media. The gas outflow duct for discharging waste gas from a bioreactor vessel is divided in a cooling zone of the heat exchanger into a multiplicity of subducts and is extended in a heating zone of the heat exchanger to a calming zone. Due to the multiplicity of subducts, a considerably larger surface area for the removal of heat from the waste gas is available, with the result that in the case of laminar flow of the waste gas through the subducts a high effectiveness of the separation of liquids from the waste gas can be achieved. In the heating zone, the waste gas can heat up again due to the reduced flow rate until it reaches the hydrophobic sterile filter by way of taking up heat from the surroundings to a such a degree that the relative vapor contents are below 100% and separation of liquids from residual vapors at or in the hydrophobic sterile filter is precluded.

The invention discloses a method for preparing chromium salt. The method is characterized by comprising the following steps: sufficiently and uniformly mixing a raw material containing chromium oxide (chrome ore or chromium slag) with sodium carbonate, carrying out oxidizing roasting at the roasting temperature of 900-1100 DEG C for 0.5-2.5 hours in an atmosphere with the oxygen content of higher than 20% by using microwaves as a heat source, leaching the roasted product with water, and preparing chromium salt from the leach solution.
