Bipolar reverse osmosis and EDI ultra pure water equipment

Bipolar reverse osmosis and EDI ultra pure water equipmentIt adopts pre-processing and reverse osmosis technologyA water treatment equipment that uses methods such as ultra purification and post-treatment to remove almost all conductive media from water, as well as to remove colloidal substances, gases, and organic matter that do not dissociate from water to a very low level.

The process flow and advantages of ultrapure water equipment,The equipment usually consists of a preprocessing section, a reverse osmosis host section, and an EDI processing section.

1. Pre treatment reasons include quartz sand filter, activated carbon filter, fully automatic water softener, precision filter (our company uses fully automatic control valve head), and ultrafiltration system can also be used as pre-treatment, but usually the engineering cost is high. The main purpose of pretreatment is to remove sediment, rust, colloidal substances, suspended solids, color, odor, and biochemical organic matter contained in raw water. When the hardness of the raw water is high, a fully automatic water softener can be selected, which effectively protects the reverse osmosis membrane and extends its service life.

2. The reverse osmosis host mainly consists of a high-pressure pump, membrane housing, imported reverse osmosis membrane components, online instruments, control electrical components, etc. As long as the number of membranes and the model selection of pumps are appropriate, the desalination rate and water production of the reverse osmosis host can reach the rated indicators, and the effluent conductivity can be guaranteed to be below ≤ 10us/CM (the original water conductivity is less than 500us/cm, and the working temperature is 1-40 ℃)

3. The post-processing part is to further refine the pure water produced by reverse osmosis to produce ultrapure water, usually using ion exchange mixed bed equipment or EDI equipment. According to customer requirements, the effluent resistance can reach 18.2 M Ω CM， If it is applied to the direct drinking water process, a sterilization device, usually a UV sterilizer or ozone generator, can be added to make the produced water meet the direct drinking standard.

Bipolar reverse osmosis and EDI ultra pure water equipmentFeatures:

1: High degree of integration, easy to expand, increasing the number of membranes can increase processing capacity.

2: High degree of automation, automatic shutdown in case of malfunction, with automatic protection function.

3: The membrane module is made of composite membrane rolls and exhibits higher solute separation and permeation rates.

4: Low energy consumption, high water utilization efficiency, and low operating costs.

5: Reasonable structure and small footprint.

6: Advanced membrane protection system, when the equipment is turned off, the desalinated water can automatically flush the membrane surface pollutants clean, extending the membrane life.

The 7 systems have no vulnerable components, do not require extensive maintenance, and operate effectively for a long time.

8: The equipment is designed with a membrane cleaning system and a scale inhibition system.
