Structure of industrial RO water filtration system

1.    Pre-filtration equipment

This is the first stage of the water filtration process, helping to treat the raw part of the input water source, meaning the water will be removed from suspended substances and heavy metal chemicals. To do that function, this part is made up of a high-pressure pump system and large filter columns, also known as coarse filter columns.

Each filter cylinder will be structured and have different functions

– Filter column number 1: Contains sand, silica, and gravel, which is responsible for removing dirt, mud, and plankton impurities from the water

– Filter column number 2: Consisting of charcoal and activated carbon, they will remove toxic substances dissolved in water such as ammonia, sulfur, sulfur-based toxins, and phosphorus.

– Filter column number 3: This filter column has the function of softening water, reducing hardness to help prevent residue from clogging the RO membrane behind

– Fine filter column: Helps filter remaining suspended sediments of 5 Micron or more

2.    High pressure pump in the system

To operate an industrial water filtration system, water pressure is needed to pass through all filters, especially RO filters. The high-pressure pump device will take on this task, designed extremely specifically, when operating, they create water pressure high enough for the osmosis process to take place quickly in the RO membrane. The pressure of an industrial pump can reach up to 200 – 230 PSI, with the ability to operate continuously 24/7.

3.    RO filtration equipment in industrial filtration systems

After being processed through the pre-filtration stage, water will be transferred to the RO membrane filtration stage, which is considered the heart of the entire industrial water filtration system.

RO filter can remove TDS, impurities, viruses, and harmful bacteria in water. Depending on the quality of input water as well as filtration capacity, the supplier will arrange different numbers of RO filters. The more RO membranes there are, the greater the capacity to produce pure water

4.    UV ultraviolet lamp

 UV helps eliminate up to 99% of bacteria, helping to ensure safety when we use that water source in daily life. UV is a disinfectant but does not chemically change the taste or smell of water like chlorine.

5.    Control unit

Besides the filter core parts and high-pressure pump, for the entire industrial water filtration system to operate smoothly, a suitable control system is needed. This system includes electronic circuit board systems, pressure gauges, meters displaying input and output water parameters. With these modern control systems, the water filtration process is completely closed implementation.

Installation process of industrial RO water filtration system

Step 1: Receive customer request information

Step 2: Technical staff survey and consult directly with customers

Step 3: Research and provide solutions for RO filtration systems

Step 4: Installation and construction

·      The device must be installed in a dry place, covered from sun and rain to avoid the effects of weather and humidity that can damage electrical equipment and contacts.

·      The installation space must be spacious enough for the operator to operate

·      Place the pure filter in the appropriate location and according to the manufacturer’s standards (The order of the filter columns is sand filter column → activated carbon filter column → water softener column → fine filter column → RO membrane)

·      Devices must be placed on a flat, solid surface

·      The purified water tank is not higher than 1.5m from the outlet of purified water and wastewater

·      Install the input, output and power lines according to the circuit diagram instructions

Step 5: Check and operate the system and evaluate the water output after installation.
