Continuous biowaste sterilization process, the operability of which is
ensured in such a way that during process startup, extreme conditions
possibly coming into question during operation are simulated, i.e. the
greatest possible flow rate and the lowest temperature of the feed flow.
In the startup stage, a liquid to be sterlized is circulated in the
apparatus, until the capacity has been ascertained, whereafter the
discharge stream can be conducted to a sewer system. The apparatus
according to the invention comprises, in the flow direction of the
biowaste-containing liquid, a storage tank, at least one feed pump
capable of delivering a constant flow, at least one heating unit, at
least one cooling unit, and a circulation circuit for circulating the
biowaste-containing liquid through the heating unit, as well as
connecting piping and valves. By means of specific piping and valve
arrangements it is also ensured that all parts of the apparatus can be
sterilized for maintenance purposes.
