Reverse osmotic dirt is a chemical preparation used to prevent stains and pollutants accumulation on the reverse osmosis membrane. The following is a basic formula for a common reverse osmosis dirt:
Organic acid: such as citric acid, oxalic acid, or acetic acid. Organic acid can dissolve and remove alkaline soil ions such as calcium and magnesium.
Phosphate: For example, sodium phosphate or sodium phosphate. Phosphoric acid can form a soluble complex with calcium and magnesium to prevent it from depositing.
Correspondence: For example, EDTA (ethyleine tetharium) or citric acid can form complexes with metal ions to prevent it from depositing.
Surface active agent: For example, sodium (SDBS) (SDBS) or sodium sodium sulfate (SDS). Surface active agents can improve wetting and decentralization, and evenly disperse the stuffing agent in the solution.
Note: The specific formula will be different due to application requirements, water quality, and reverse osmosis equipment. When using a stuffing agent, we should follow the guidance and suggestions provided by the manufacturer, and use it in accordance with the correct proportion and method.
