Counter Flow fume scrubbers are designed for contaminants, which
are difficult to absorb for all airflow requirements. The Counter
Flow design offers advantages in the efficient and effective use
of scrubbing solutions, as well as in a higher separator efficiency,
especially for deep beds of packing. High removal efficiency is
advantageous where the contaminants are highly offensive or have
recovery value. In this design mist and separating solutions carry-over
at high gas velocity is minimized by the use of dry packed bed
mist eliminators.
Counter Flow separators are available with a variety of tower
internals; each designed to achieve a maximum in efficiency at
a minimum of cost. The separators are available with packed beds
in height ranging from 1.2 metres to 6.0 metres.
The choice between B and C Series separators must be based upon
headroom required separating efficiency and future exhaust requirements.
Series B separator internals may be modified so as to achieve
separating efficiency equal to Series C separator.
Standard
fume separators are packed with 50mm plastic tower fill, eg tellerettes
give a higher target efficiency with mist and light dust problems.
