1. Low pressure flushing ro device
The regular ro device for large flow, low pressure, low pH flushing conducive to divest attached on the membrane surface of dirt, maintain membrane performance, or when ro device feed SDI rise suddenly 5.5 above should be carried out when the low-pressure flush, stay SDI value moves to a qualified again after the boot.
2. Ro device etc protection
Due to production fluctuations, ro device inevitably will often lines, short-term or long-term discontinuation necessary to take protective measures, improper handling can cause membrane performance degradation and can be reused.
Short-term preservation applies to 15d service system, which can adopt the following every 1 ~ 3d low-pressure flush ways to protect ro device. Practice found that more than 20 °C temperature, ro device of water storage 3d stink metamorphism, there are large bacterium is progenitive. Accordingly, the proposal is above 20 °C water, every 2d or 1d low-pressure flush again, water temperature below 20 per °C may, when washing a 3d low-pressure after rinse, every time should be shut off water purification equipment reverse osmosis device all import and export valve.
Long-term discontinuation protection applies to 15d service above system, then must use protect fluid (fungicides filling water purification equipment reverse osmosis device to protect. Common fungicides formula (compound membrane) for formaldehyde 10 (mass fraction) and isothiazolinelcetone 20mg/L and hydrogen sulfite of sodium 1 (mass fraction).
3. Reverse osmosis membrane chemical cleaning
In the normal operation conditions, reverse osmosis membrane may also be inorganic scale, colloid, microbe, metal oxide polluted, these substances deposition in the membrane surface will cause water purification equipment reverse osmosis unit output declines or desalination rate drop, differential pressure increases, even on membrane causing unrecoverable damage, therefore, in order to restore good waterproof, and salt performance, except to film chemical cleaning.
Generally 3 ~ 12 months to be cleaned, if every month had to be cleaned, this shows that should improve the pretreatment system, adjust the operating parameters. If 1 ~ 3 months need to be cleaned, is needed to improve equipment operation level, whether to need to improve the pretreatment system more difficult to judge.
