This gas is typically well dispersed through the brine initially as very minute incipient gas bubbles that will accumulate and separate from the brine, given sufficient time. A method is herein provided for quickly and efficiently clarifying the brine by passing the cloudy brine through a filter zone providing a pressure drop across the zone of greater than about 20 p.s.i. g.
