摘要： The invention concerns a method and a device for the selective extraction of the halide ions from photographic baths. According to the invention, the solutions to be treated are subjected to a first nanofiltration step 2 in diafiltration mode, then to a second nanofiltration step 3 in concentration mode. The method makes it possible to prolong the activity of the fixing or bleaching/fixing baths during the processing of photographic products.

摘要： Spent solutions from photographic processors are fed into a conduit (18) to which subsequently are added precipitating agents from a first source (22) and flocculating agents from a second source (28); so that, well grown or ripened clumps of flocculated solids are formed along the conduit before being emptied into a gravity collecting vessel and shipping container (38) from which clarified liquids are displaced by a mass (50) of accumulated flocculated solids, typically through a filter (58, 142, 150, 158, 162, 166, 220)for removal of any unsettled fines. Many of the clumps of flocculated solids become enlarged enough to individually extend across and substantially fill a cross-sectional area of the conduit. As a result, the enlarged clumps substantially block passage of and strain from the solution remaining fine particles which then adhere to the clumps.

摘要： An electrochemical cell (50) for deionizsation utilizes electrochemical ion-exchange to remove ions from a feed solution. Under the influence of an electric field, ions are adsorbed into, are scored within and pass through a permeable layer (54, 64) of particulate ion-absorbing material and binder, the sheet being several millimeters thick. Water from the feed solution also permeates through the layer (54, 64), so a concentrated solution of the ions emerges from the rear (58) of the layer. The cell does not require separate sources of feed and eluant solutions and can be operated substantially continuously. In a modified cell (70) the flow path for the feed solution passes through a highly porous ion exchanger structure (77), which may be located between two such microporous layers (54, 64). Absorption in such a cell may be effective in the absence of an electric field, elution requiring the periodic application of the electric field.

摘要： It is known to treat the effluent resulting from photographic processing apparatus. Such treatment takes the form of either neutralization where the effluent is mixed with a neutralizing solution prior to disposal, or evaporation where the effluent is heated to form a precipitate and a concentrated liquid portion prior to disposal. However, both these techniques have disadvantages they do not account for toxic particles which may be suspended in the solutions. Described herein is apparatus in which photographic effluent can be treated to provide harmless end products which can be disposed of directly. The apparatus comprises a mixing unit (10) in which the effluent (S1) is mixed with treatment chemicals (S2, S3, S4, P1, P2, P3) and is then passed to a separation unit (20) in which the treated effluent is separated into non-toxic liquid and solid phases. A computer (100) is used to control all stages of the treatment of the effluent.

摘要： The present invention relates to a method for regenerating tetraalkylammonium hydroxide used as developer solution for positive type resist from waste developer solution. Waste solution from developer solution for positive type resist, which contains tetraalkylammonium hydroxide as principal component, is neutralized, and after depositing and removing alkali-soluble organic substances dissolved in it, it is electrolyzed in an anode chamber of an electrolytic cell partitioned by cation exchange membranes, and it is anodized in the anode chamber. Aqueous solution of tetraalkylammonium hydroxide obtained from the cathode chamber is further introduced to an anode chamber of the other electrolytic cell to perform multi-stage electrolysis or it is introduced into an anode chamber of an electrolytic cell partitioned into 3 chambers or more by two or more cation exchange membranes to perform multi-chamber electrolysis. The electrolytic solution of the intermediate chamber is circulated to an electrolytic cell for decomposing organic substances and electrolyzed, and tetraalkylammonium hydroxide, which can be re-used as developer solution, is obtained from the cathode chamber of the final stage electrolytic cell or from the cathode chamber of the multi-chamber electrolytic cell.
