Title:
PROCESSING METHOD FOR WASTE PHOTOGRAPHIC PROCESSING LIQUID
Document Type and Number:
Japanese Patent JP3187175
Kind Code:
B2
Abstract:
PURPOSE: To simplify a power source, to facilitate the recovery of silver and to enable the recycling of the electrolyzed liquid after silver recover as a photographic processing liquid as it is by making it possible to use the waveform of an AC power source for household use after waveform rectification by a current rectifier circuit.
CONSTITUTION: This method consists of electrolytic processing of waste photographic processing liquids by using the single phase incomplete current rectification power source, increasing of the quantity of electricity on the minus side of a cathode base larger than the quantity of electricity on plus side at this, using a single phase incomplete current rectified power source obtained by waveform shaping of the waveforms of the AC power source for household use by a current rectifier circuit or a single phase incomplete current rectification power source obtd. by rectifying house hold power and regulating the period.
