Methods and apparatus for controlling the supply of a feed gas to dissolution devices

摘要: The supply of a gas to be dissolved in liquid is controlled by initially sensing the concentration under treatment and subsequently producing appropriate control signals for adjusting setting valve line. A dissolution device emplaceable includes inlet outlet static liquid-gas mixing means therebetween. adapted receive supplied whereby space upper reaches established. also maintained communication with dip tube disposed exteriorly body lower extremity establishing maximum height within device. comprises gravitational fall such that upon detecting an increase or decrease liquid, zone reduced increases, respectively, thereby decreasing increasing rate dissolution. Upon reducing electrical power necessary pump through conserved. In this manner, correlated demand therefor wastage effect gas-liquid substantially avoided.
