1000LPH Drinking Water RO Treatment System Water Desalination Plant
Does the frequent start and stop of the drinking water ro system has a great impact on the equipment?
If the reverse osmosis pure water system is designed for continuous operation, in actual operation, there will be start and stop at different frequencies. When the membrane system is out of operation, low-pressure flushing with its produced water or pretreated water should be used to replace the concentrated water with high concentration but containing scale inhibitor in the membrane element. It should also be considered not to introduce air due to system leakage, because if Parts lose water and dry out, and irreversible permeate flux loss may occur.
If the machine is down for 24 hours, no action is necessary. However, if the downtime exceeds the above provisions, the protective solution storage system or the membrane system should be flushed regularly to reduce the impact on the equipment caused by the start-up of the equipment.
Operating environment of drinking water RO system:
1. Indoor ambient temperature: 5~35℃.
2. Temperature: 80% larger.
3, to achieve no pollution, no vibration.
4. The room should be cool, dry, ventilated, and avoid direct sunlight.
5. The installation ground of the equipment is guaranteed to be flat, drainable and water will not leak.
6. The equipment installation room meets the space area required for the equipment to work.

Composition of drinking water RO system:
Drinking water reverse osmosis system includes pretreatment system, reverse osmosis device, post-treatment system, cleaning system and electrical control system. The purpose of pretreatment is to make the raw water meet the inlet requirements of the ro membrane separation unit and ensure the stable operation of the ro purification system. Reverse osmosis membrane system is the most economical and efficient purification method to remove more than 98% ions, organic matter and 100% microorganisms in raw water at one time. The ultra-purification post-treatment system further removes trace ions, organics and other impurities in the reverse osmosis pure water through a variety of integrated technologies, so as to meet the requirements of the final water quality index.
FAQ:
1, What are the inlet water quality requirements for ro water treatment system membrane components?
| | NTU | SDI | Residual chlorine(mg/L) | Fe2＋(mg/L) | TOC(mg/L) |
| Limits | ≤1 | ≤5 | ≤4 | ≤3 |
2. What is the material of ro water treatment system membrane?
Acetate membrane (CA) : mainly because of its resistance to chlorine, so it is still durable. But its suitable pH range is small, easy hydrolysis
Aromatic polyamide membrane (PA) : water almost can not have chlorine, only through a variety of pretreatment chlorine.
3. RO water treatment system configuration:
First-stage multi-stage process: if the recovery rate is not achieved in the first stage (50-65% in the first stage and 65-75% in the second stage), the multi-stage tandem filtration can be used. The effective cross-sectional area of each segment decreases. 2:2 and 2:3 and 4:2:1
Multi-stage process: when the first stage process cannot meet the effluent quality requirements (the first stage is generally ≤20μs/cm), the product water of the first stage process is sent to another reverse osmosis unit.
The arrangement of membrane components can be divided into series and parallel.
