摘要： In an electrolytic bath, an extraction part extracts heavy metal in the internal organs of scallops into an acid solution. A direct current voltage is applied between electrodes, which are provided in the acid solution, to deposit the heavy metal in the acid solution on the electrodes. If the deposit efficiency deteriorates, the polarity applied between the electrodes is reversed from the polarity in the deposition of the heavy metal in a neutral or alkali electrolytic solution. Consequently, the heavy metal is removed from the electrodes. Since arsenic is dissolved in the acid solution, an alkali liquid and a flocculant are added to the acid solution to sediment arsenic.

摘要： An electronic noise attenuation system for attenuating a sound wave propagated from a source of noise by generating another sound wave 180 DEG out of phase and having the same sound pressure with the propagated sound wave from electro-mechanic transducer means disposed in a propagation passage of sound waves. In the electronic noise attenuation system, a drive signal for drive the electro-mechanic transducer means is generated in accordance with output signals respectively output from upstream-side and downstream-side mechano-electric transducer means respectively disposed in the propagation passage with the electro-mechanic transducer means therebetween. Namely, the drive signal is created by performing an operation on a difference signal between the output signal of the upstream mechano-electric transducer means and the drive signal according to a given transfer function. Also, the transfer function is determined in accordance with the difference signal and the output signal of the downstream mechano-electric transducer means.

摘要： Dialysis apparatus has dilution and concentration chambers arranged alternately, which chambers each are defined by ion exchange membranes and frames each disposed therebetween. Passages for introduction of air into the dilution and concentration chambers are provided at lower portions thereof. The air introduced through the passages into the dilution and concentration chambers rises upward between the ion exchange membranes and is exhausted from upper portions thereof out of the dialysis apparatus. By the introduction of the air, solutions in the dilution and concentration chambers are driven to flow upward. Condensed phosphates are added to liquid to be treated before dialysis of the liquid.

摘要： Waste water issued from a wet type desulfurization apparatus and containing thionic acid ions is introduced into ion-exchange towers filled with weak-basic anion-exchange which has to effect anion exchange therein. The weak-basic anion-exchange resin which has adsorbed the thionic acid ions is desorbed by contacting an alkaline solution. The thionic acid ions included in the desorbing solution are decomposed by heating them in the presence of acid. A decomposed solution is issued out of the system after its neutralization.
