RO cleaning agent 
 One. Introduction: 
 Membrane tubes weak acidic cleaning agents are the main components of the type of organic acid composition, specifically designed to remove iron oxide blockage of membrane cleaning agents, while the mild removal of calcium carbonate scale also has a good effect. This weak acid commonly used membrane cleaning agents, they must first ensure that all of the organic membrane have been to get rid of. 
 Two. Functions and features: 
 ? High concentration of active ingredient 
 ? Blockage can be removed with mild iron oxide, calcium carbonate and other scale 
 ? Weak type of organic acids will not cause damage to the membrane 
 Three. To add: 
 1 using low pressure reverse osmosis water production first rinse to remove the device and run the water when the concentration of pollutants. 
 (2) to free chlorine (chlorine free) dilution of reverse osmosis product water production, preparation of the concentration of 4% w / w solution. Cleaning solution adjusted to pH of about 2.5-4.0, the temperature about 20-30 ℃; necessary, ask membrane manufacturers and system builders to determine the most appropriate cleaning pH and temperature. 
 3 The initial cleaning should be the beginning of the first 20% of cleaning solution as the membrane flushing, and their emissions out, do not return to the RO cleaning tank, but also emissions from the system off the top of the water. 
 4 can be segmented cleaning cleaning cleaning time depends on the membrane were blocked with iron oxide scale the extent to which the general cleaning time is 2 to 3 hours, it is recommended to take turns every 15 minutes for the interaction cycle and soak operation. 
 5 cleaning, if the cleaning solution pH rises above 0.5, said cleaning agent has been consumed more, please re-add the product to the original cleaning solution pH. Please use this product after the lye to be in and prior to his discharge. 
 6 After the washing step, the product must be low-pressure water wash membrane to remove any residual drug, this can be instructed by the pH meter reading to determine, with drainage into the water when the pH value of the same, that is be sure to complete cleaning. Line on the system before the first phase of mining water 5 to 20 minutes or more, please adopt water discharge, the water will not be taken to ensure that residual cleaning agent. 
 Four. Drug standards:
