HQQ-5062 RO cleaning agent - Yunnan Hao spring deal
◆ RO systems up and running in the maintenance and management of the condition, every 3 to 6 months period of time, will also be inorganic fouling of reverse osmosis membranes, colloids, microorganisms, such as the gradual accumulation of pollution, metal oxides, because the RO membrane water quality control can only handle a relatively safe target range, and these indicators, the lower, RO membrane is less possibility of contamination, the longer the period of contamination;
◆ these substances (contaminants) deposited on the membrane surface caused a decrease or reverse osmosis desalination plant output rate of decline, can not meet water requirements; the film pressure increased, even causing irreversible membrane mechanical injury; Therefore, in order good recovery and desalination performance of porous, Yasumasa RO system operating parameters in the most reasonable range, must be timely to develop targeted programs for chemical cleaning of RO membrane;
◆ RO system for cleaning chemicals are all relatively strong acidic or alkaline, these formulas are complex chemicals, the cleaning effect through complex co-synthesis, to restore the purpose of cleaning; and control of cleaning fluid conditions are controlled at the edge of RO membrane can withstand the value of the RO membrane and high pressure pump impeller, etc. There are certainly some damage; Therefore, in daily operation, management and use of fine chemicals targeted routine maintenance is necessary, avoid frequent cleaning of the RO system is necessary.
One. Conditions need to be cleaned
1.1 RO plant routine maintenance, the normal operation after 3 to 6 months;
1.2 RO membrane water yield than the normal water production decreased by 10% to 15%;
1.3 The rate of penetration of salt through the salt than normal rate of increase of 10%;
1.4 RO system, all or part of the pressure difference across the membrane increased by 10% to 15%;
1.5 RO unit stops for long ago;
Under normal operating conditions (temperature fluctuations small), the event any of these conditions, the proposed RO membrane cleaning.
HQQ-5061/5062 special cleaning agent, is designed specifically for high-performance RO membrane cleaning liquid compound formulations for the removal of RO membrane surface of the metal hydroxides, inorganic scale (carbonate, sulfate, silicate, and other chemical sediments, etc.), organic fouling (slime, mucus, gel, algae, etc.);
It applies to all composite RO membrane, membrane sodium, etc. This series of products to remove dissolved strongly attached to the membrane of various organic and inorganic scale, low-foam or no foam, after several sets of 50 tons / hour capacity of water RO systems, and its excellent cleaning effect, the RO system security recovery operation in the most reasonable range of parameters;
This series is divided into basic or acidic organic compound formula, cleaning parameters are controlled within the requirements of RO membrane elements, on the membrane without chemical damage.

"Calculation of the actual cleaning parameters"
IV. Use Description
Cleaning agents are usually the dilution ratio is the volume of the cleaning system 3 to 8%, the specific ratio of RO system based on individual device to be the actual pollution Weibang company by the local service engineer according to the scene to determine the final ratio. HQQ-5061 mainly for biological fouling and colloidal contamination particularly effective; HQQ-5062 mainly for the metal oxide, carbonate, sulfate, silicate, and other chemical sediments, colloids and other pollution are particularly effective.
5.1 Check the cleaning circuit: cleaning tank, hoses and the security filter has been connected with demineralized water clean, wash at least 2 times.
5.2 In addition to inorganic dirt and chemical scale: using reverse osmosis water or demineralized water through the cleaning tank half into the volume of the budget will have a good HQQ-5061/5062 reverse osmosis cleaning agent injected into the cleaning tank slowly, continue to saline injection in addition to 90% of the volume, mixed with a cleaning solution circulation pump; conditions permit, the use of steam heating the mixture to the membrane manufacturer the maximum temperature for better cleaning effect can be.
5.3 cleansing loop, start cleaning the pump, start cleaning, the initial outflow of RO membrane cleaning solution should be discharged out of the system, cleaning the tank volume is about 10 to 20%, cleaning flow, the flow rate should be in accordance with the membrane manufacturer or system supplier's recommended value of 0.5 to 2 hours cleaning time, cleaning is completed the cleaning fluid discharged into the sewage treatment station directly, using demineralized water will wash clean container and loop back;
5.4 start the reverse osmosis system flushing procedure, flush the surface of RO membrane system, 30 to 60 minutes.
5.5 In addition to organic scale: methods with the addition of inorganic scale method.
5.6 The multi-stage RO system, each individual can get the maximum cleaning effect.
