| titleOfInvention | Cleaning process for RO (reverse osmosis) membrane for recycling reclaimed water of electrolytic copper foil |
| abstract | The invention discloses a cleaning process of a cleaning combination formula of an RO (reverse osmosis) membrane for recycling reclaimed water of an electrolytic copper foil. The cleaning combination formula comprises alkaline cleaning solution and acidic cleaning solution; the alkaline cleaning solution comprises a first cleaning solution, a second cleaning solution, a third cleaning solution and a seventh cleaning solution; the acidic cleaning solution comprises a fourth cleaning solution, a fifth cleaning solution and a sixth cleaning solution. Through rinsing first washing liquid, the second washing liquid, the third washing liquid, the fourth washing liquid, the fifth washing liquid, sixth washing liquid and seventh washing liquid wash the RO membrane in proper order, can effectively clear away the organic colloid in the RO membrane, the macromolecule organic matter, the micromolecule organic matter, the bacterium, the scale deposit of inorganic salt, suspended solid and alga, the scale deposit of organic salt, mediation RO membrane hole, resume the normal water production of RO membrane, the life of RO membrane has been increased, the rate of utilization of RO membrane has been improved, and then use cost has been reduced. |
