1、 Equipment name: RO cleaning equipment

2、 Specification and model: hdnro

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

At present, the international advanced reverse osmosis membrane separation technology is used to produce industrial ultra pure water. Reverse osmosis technology is an advanced water treatment desalination technology. The reverse osmosis membrane (the liquid separation membrane which uses the reverse osmosis principle for separation) principle for separation, the specific characteristics are as follows:

① Under the condition of no phase change at room temperature, the solute and water can be separated, which is suitable for the separation and concentration of thermosensitive substances. Compared with the separation method with phase change, the energy consumption is lower.

② The separation technology of reverse osmosis membrane (the liquid separation membrane which uses the principle of reverse osmosis for separation) has a wide range of impurities removal. For example, the separation and removal of more than 99.5% of heavy metal ions in water, carcinogens, fertilizers, pesticides and bacteria.

③ High desalination (removal of anions and cations in water) and water reuse rate can intercept solute with particle size more than several nanometers.

④ Low pressure is used as the power of membrane separation, so the separation device is simple, operation, maintenance and automatic control are simple, and the site is safe and sanitary. 　

5. Technical principle:

The phenomenon of deep penetration is common in nature. For example, if a cucumber is put into salt water, the cucumber will become smaller due to water loss. The process of cucumber water molecules entering into saline solution is the infiltration process. As shown in Figure 1, if a water pool is separated into two parts by a membrane that only water molecules can penetrate, pure water and salt water are injected into both sides of the membrane to the same height. After a period of time, it can be found that the level of pure water has decreased, while the level of salt water has increased. The phenomenon that we transfer water molecules through this membrane into brine is called osmosis. Salt water level rise is not endless, to a certain height will reach a balance point. At this time, the pressure represented by the liquid level difference at both ends of the diaphragm is called osmotic pressure. The osmotic pressure is directly related to the concentration of brine.

Electronic, electroplating, electrophoresis, battery, vacuum coating, detergent, cosmetics, glue, chemical industry, pigment, surface treatment, brackish water treatment, etc. 

And can be applied as follows:

◇ RO pure water device is the primary desalting equipment for ultra-high pure water production.

◇ Water for electronic industry: integrated circuit, silicon chip, display tube and other electronic components, PCB flushing water

◇ pharmaceutical industry water infusion, injection, tablet, biochemical products, equipment cleaning, etc;

◇ ultra pure water for other processes, such as water motorcycle parts, home appliance coating, coated glass, cosmetics, fine chemicals, etc.

7、 Equipment advantages:

◇ continuous operation, stable product water quality

◇ regeneration without acid and alkali

◇ no shutdown due to regeneration

◇ save water for recoil and cleaning

◇ produce ultra pure water with high yield (up to 95%)

◇ no recycled sewage, no sewage treatment facilities

◇ no need for acid-base storage and acid-base dilution transportation facilities

◇ reduce workshop building area

◇ safe and reliable use, avoid workers from contacting acid and alkali

◇ reduce operation and maintenance costs

◇ Easy installation and low installation cost

8、 Shutdown maintenance:

The reverse osmosis in production must be flushed every time it is started and stopped for replacement, its purpose is to flush away the accumulated salt on the membrane surface, especially when it is stopped; the specific maintenance methods for the long-term or short-term shutdown of reverse osmosis must be as follows:

1. Shutdown for 1-3 days, Wash the RO system with low pressure (0.2kg-0.4kg) and large flow every day for 15 minutes. It is better to wash with desalted water.

2. After shutdown for more than 7 days, the desalted water flushing method shall be used first, and then 0.5% sodium bisulfite solution shall be used for soaking and sealing.

3. If the system is shut down for more than 10 days, seal it with 0.5% formalin solution and replace it every 30 days.

1. The system equipment is entitled to one-year free warranty, the warranty date is calculated from the date of product acceptance, and the consumable filter material is not listed here.
2. In case of any equipment quality problem (except caused by misoperation or unforeseen factors) during the warranty period, the supplier shall repair it free of charge and replace the damaged parts.
3. After the expiration of the warranty period, only a certain material fee and appropriate technical service fee will be charged.
4. In case of system operation failure which cannot be solved by itself or by telephone, our technical maintenance personnel shall make solutions (including temporary measures) and schedule within 24 hours after receiving the written notice from the demander and report to the competent leaders of both parties.
5. After the delivery of the equipment, our company will have engineers to pay a return visit to understand the operation of the equipment and provide technical services in a timely manner. Users are welcome to ask any technical questions, and we will reply in time.

① the user shall provide detailed data of raw water test, so that our company can carry out relevant selection and arrangement calculation.
② the user shall explain the water quality requirements, use and water yield of the produced water.
③ our company has many types of pressure vessels, membranes, accessories, etc. if the user gives special instructions, we will try our best to meet the requirements.
④ our company provides installation and debugging for the designed and sold equipment and training for the user's operation personnel.
⑤ our company implements the principle of one-year equipment warranty and lifelong service for users, and establishes archives for tracking service to ensure the quality level.

If the above equipment fails to meet your requirements, please contact us, and we will make a detailed engineering plan according to your actual situation, to achieve a low-cost, high efficiency and scientific process combination, so that the water production can meet your ideal requirements.
