Electroplating deionized water equipment, industrial pure water treatment equipment, 5t/h ultra pure water device

1、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hOverview of Ultra Pure Water Device:

Deionization ultra pure water equipmentIt is mainly composed of reverse osmosis and mixed bed. The reverse osmosis device is mainly powered by the pressure difference on both sides of the membrane, allowing only water molecules to pass through while intercepting other ions except for hydrogen and oxygen ions. The removal rate of various ions is also different due to its structure and principle. According to statistics, the removal rate of trivalent ions by reverse osmosis is about 95% -99%, the removal rate of divalent ions is about 92% -99%, and the removal rate of monovalent ions is about 70% -95%. The removal rate of divalent anions is 80% -90%, the removal rate of monovalent anions is around 75% -95%, and the removal rate of nitrate ions is 50% -75%. Reverse osmosis membrane is the core component of purified water, and Green Health Company's reverse osmosis membrane mainly uses American brands such as Heideneng or Dow, with 5 8-inch RO membranes. pass throughReverse osmosis pure water machineThe water still cannot meet the purity requirements for process water, so a mixed ion exchanger is added for deep desalination. The mixed bed section is equipped with a mixed bed booster water pumpMixed ion exchange bedComposed of resin catcher and mixed bed regeneration device.

Mixed ion exchanger, abbreviated as mixed bedCation exchange resinThe chemical desalination equipment, which is placed in the same exchanger and mixed evenly during operation, produces high purity effluent.

2、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hDesign parameters for water production of ultrapure water device:

1) Deionized water production: 5T/H;

2) Produced water quality: SiO2 ≤ 20.0 μ g/L;

3) The resistivity is ≥ 10 megaohms.

3、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hAuxiliary configuration of reverse osmosis system in ultrapure water device:

The reverse osmosis device is equipped with an automatic fast flushing discharge valve. Stainless steel valves and fittings are used for the high-pressure pump section, and UPVC fittings are used for the low-pressure section to ensure the normal operation of the entire process. The reverse osmosis device is also equipped with flow meters, conductivity meters, pressure gauges, and other indicators to monitor the operating conditions of the RO device. Each set is equipped with a sampling valve and a centralized sampling disk, which can be used to sample and detect water quality at any time.

Chemical cleaning water pump is installed for reverse osmosis concentrated water, and the water pump can be turned on for cleaning when the reverse osmosis membrane is clogged.

4、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hComposition of mixed bed in ultrapure water device:

The mixed bed booster pump is mainly used to provide the necessary water supply pressure and flow rate for the normal operation of subsequent equipment. The system uses the raw water booster pump from Southern Pump Company, which has the characteristics of small volume, high efficiency, and low noise.

Mixed ion exchange bed: The system is equipped with one mixed ion exchange bed with a diameter of 600, and each mixed ion exchange bed is configuredresistivityThe tester controls the resin regeneration cycle based on the output water resistivity parameter value. When the water resistance value of a mixed ion exchange bed is less than the set value, it stops running and regenerates, while the standby mixed bed is put into operation.

Resin trap: Install one resin trap in the outlet pipe of each mixed ion exchange bed, and install a backwash pipe to facilitate the emptying of resin from the resin trap.

Regeneration device: Install a set of mixed ion exchange bed regeneration devices that are compatible with the system, consisting of one acid-base metering box, two sets of water injectors, and one regeneration water pump.

The mixed bed produced water is stored in a desalination water tank after adjusting its pH value through an ammonia addition device. The ammonia dosing device consists of a metering pump and a metering tank, and the pH value is monitored online by a pH meter. The desalination water tank is equipped with a liquid level sensor that can detect, display, and control the liquid level of the desalination water tank at any time. When the desalination water tank reaches a high liquid level, the mixed bed will automatically shut down; When the desalination water tank reaches the intermediate liquid level, the mixed bed will automatically start.

5、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hKey operating points of ultrapure water device

The cleaning and regeneration of pure water equipment, as well as the pre-treatment of quartz sand and activated carbon filters, mainly involves regulating valves. During operation, the filter operates in an upward and downward manner, while backwashing and regeneration allows water to enter and exit underwater. Wastewater is discharged through the drain valve. Generally, quartz sand is replaced once every 1-2 years,activated carbonReplace once every 1-2 years. Reverse osmosis pure water equipment is widely used for drinking in daily life, such as drinking pure water, bottled drinking water, seawater desalination, industrial chemical pure water, mechanical flushing pure water, coating pure water, and so on

6、 Electroplating deionized water equipment,Industrial pure water treatment equipment, 5t/hAttention should be paid to the following points when installing ultra pure water equipment:

1. Reverse osmosis installation should be placed indoors, such as installing a ceiling outdoors.

2. Reverse osmosis should be placed horizontally.

3. Before running reverse osmosis, the quartz sand and activated carbon should be repeatedly washed to determine the clean position of the effluent. The ion exchanger should also be regenerated and cleaned

4. When starting the equipment, pay attention to starting the front booster pump first, and then starting the high-pressure pump.
