1、 Equipment name: automatic reverse osmosis pure water equipment with frequency conversion and constant pressure water supply system

2、 Specification and model: hdnro-3000

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

1. Mechanical filter:

It is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of the water, make the turbidity of the water less than 0.5ntu, CODMn less than 1.5mg/l, iron content less than 0.05mg/l, SDI ≤ 5. Through the control valve, backwashing and forward washing can be carried out at any time to wash off the dirt on its surface, prevent its blocking and restore its filtering capacity.

2. Activated carbon filter:

Activated carbon has a very strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromatic, peculiar smell, organic matters, etc. in water. As the reverse osmosis membrane is very sensitive to residual chlorine and organics, it is necessary to configure activated carbon to absorb residual chlorine and organics, so that the residual chlorine in the outlet water is ≤ 0.1mg/l, SDI ≤ 4, and the first can meet the water supply requirements of the reverse osmosis membrane. Second, it can greatly improve the original taste of the source water. It can be backwashed at any time through multiple control valves or steam operated butterfly valves to wash away the colloid and other pollutants on the surface, prevent the surface of the activated carbon from being surrounded by impurities, prevent it from blocking, and restore its treatment capacity.

3. Security filter:

After pretreatment, a safety filter is arranged in front of the high-pressure pump to prevent the impurity particles larger than 1um from entering the high-pressure pump and damaging the high-pressure pump and reverse osmosis membrane. The PP filter element (with framework and good strength) is loose outside and tight inside, and the water is filtered from the outside to the inside, which can prolong the time when the filter element is blocked. The upper part has an exhaust valve, which can prevent air from entering the pump and damaging the pump. The lower part has a drain valve, which can discharge the retained impurities at any time.

4. RO unit:

Reverse osmosis technology is a mature desalination technology in the world at present, and it is also a water treatment technology with wide market application and wide application range. It can filter bacteria, viruses, metal ions, salts, pesticides and all kinds of carcinogens in water precisely. It has low working pressure, large water yield and high desalination rate. It is easy to maintain and design automatic washing device, which can prolong its service life. The design of automatic flushing device can prolong its service life.

5. Variable frequency constant pressure water supply system:

It refers to the water supply mode in which the outlet pressure remains unchanged when the water consumption in the water supply network changes. The outlet pressure value of water supply network is determined according to the needs of users. The traditional constant pressure water supply is realized by water tower, high water level tank, air pressure tank and other facilities.

5. Features:
◇ RO membrane automatic and manual operation / flushing, optional touch screen control, human-computer interface.
◇ RO membrane can be cleaned manually with chemicals in the machine
◇ high water level automatic stop, low water level automatic start

◇ Multi stage high-pressure pump water shortage protection and overload and overpressure protection function

◇ voltage loss, undervoltage, overcurrent, short circuit, open circuit, leakage protection

◇ the equipment is made of stainless steel, fully automatic operation, and no need for manual conduct.

◇ performance of direct drinking water:

The water purification process of water supply with different quality is the advanced treatment of tap water. It can remove harmful heavy metals, organic matters, bacteria and viruses in the water through filtration, softening, membrane separation (RO or UF) sterilization and other methods, so as to make it a high-quality drinking water (or purified water) It is directly delivered to each household through special sanitary pipes for residents to use. It is completely separated from the original tap water. The original tap water becomes daily water. In this way, the two pipelines are divided into different water quality, and the mode of supplying drinking water and domestic water is called pipeline high-quality drinking water purification, also known as water supply of different quality.

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.

◇ Electronic industry water integrated circuit, silicon wafer, display tube and other electronic components, PCB washing.

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

◇ pure water is used for other process water motorcycle parts, home appliance coating, coated glass, cosmetics, fine chemicals, etc.

1. The influent water quality is urban tap water or equivalent.

2. Technical indicators of water production:

   (1) Water production flow: 3T / h (water temperature 25 ℃) reverse osmosis

   (2) Water production standard: in accordance with national standard a for reverse osmosis equipment design (GB / t19249-2003)

   (3) In line with the national industrial deionization water quality standard cj94-2005

   (4) Conductivity ≤ 5 μ M / cm (conductivity of raw water ≤ 1000 μ M / cm)

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.
