| Item | Specification |
|---|---|
| Appearance | Colorless or pale‑yellow transparent solution |
| pH (neat) | 4.0‑6.0 |
| Density (g/cm³) | 1.15‑1.20 |
Before long‑term shutdown of large‑scale reverse osmosis systems, thorough cleaning shall be performed to remove inorganic scale, organic fouling and biological slime inside the system. The whole system shall be disinfected with reverse osmosis non‑oxidizing biocide (circulate for 30 min, followed by soaking for at least 2 hours). Rinse pipelines and membrane modules thoroughly with plenty of deionized water to ensure no residual biocide remains in the system. Prepare 3‑4 % working solution of reverse osmosis shutdown preservative, fill the whole system and close all valves for sealing. JQSY technical engineers recommend checking the pH of protective solution once a week. Replace the preservative if pH drops below 3. Normally, replace the protective solution every month.
JQSY reverse osmosis shutdown preservative is normally packed in plastic drums of 25 kg each, or customized as per customer requirements. Store in cool and dry place at ambient temperature. Shelf‑life: 12 months.
This reverse osmosis shutdown preservative is weakly acidic and has certain corrosivity to skin. Take proper labor protection during operation. Avoid contact with skin and eyes. In case of contact, rinse with plenty of clean water.
