Supply pure water equipment

1. Technical characteristics and selection principles of pure water equipment
Reverse osmosis uses physical methods without phase change to desalinate and remove salt water at room temperature. At present, the desalination rate of ultra-thin composite membrane elements can reach the above, and can simultaneously remove colloids, organic matter, bacteria, viruses, etc. in the water. Using imported reverse osmosis membranes, the desalination rate is high, the service life is long, and the operating cost is low.
, Use fully automatic pretreatment system to achieve unmanned operation
, Use imported Grundfos booster pump, high efficiency, low noise, stable and reliable
, Online water quality monitoring control, real-time monitoring Water quality changes to ensure water quality safety
, fully automatic electronic control program, and optional touch screen operation, easy to use
and personalized design that meets local water quality to meet all needs.
The equipment occupies a small area and requires little space.
The reverse osmosis device has a high degree of automation, and the workload of operation and maintenance and equipment maintenance is very small.
Water treatment only relies on water pressure as the driving force, and its energy consumption is the lowest among many treatment processes.
There is no need for a large amount of chemicals and acid and alkali regeneration treatment, no chemical waste and liquid discharge, and no environmental pollution.
. Reverse osmosis can continuously operate water production. The system is simple, easy to operate, and the product water quality is stable.
2. Pretreatment system
It is very important as the basis for pure water production. Therefore, if you want to produce pure water, you must choose a place with better raw water quality. Such as mountain springs, deep wells, etc. A very important index involved here is conductivity. Generally speaking, the conductivity is lower. The purer the water. The water treatment processes currently used are based on the desalination rate that the treated water can generally achieve, which is a component of this system.
Water Pump
The raw water pump is used to provide raw water pressure for the raw water pretreatment system. If the raw water has pressure, you don't need this equipment at all. Generally required raw water pressure
Water tank
The function of the raw water tank is simpler and is used to store raw water. This is because we are afraid that the raw water will be transferred if the supply of raw water is not available (usually adding a float switch will make the entire system more automated).
Yingsha filter
Quartz sand filter material is used to remove larger suspended solids, sediment, impurities, etc. from raw water and reduce water turbidity. It can also remove a large amount of organic matter, bacteria, viruses, etc. in the water as the turbidity decreases, and creates good conditions for post-filtration disinfection.
Activated carbon filter
Use the adsorption capacity of activated carbon to effectively adsorb organic matter, free residual chlorine, colloids, particles, microorganisms, certain metal ions and decolorization in raw water.
Chemical system (dosing system)
Utilize the exchange performance of ion resin to remove calcium and magnesium ions in raw water to prevent subsequent equipment from being affected by scale. However, the operation is labor-intensive and material-intensive. Now add antiscalant directly to it instead.
Reverse osmosis system
The reverse osmosis system is the core component of the entire pure water system. Only through reverse osmosis can the standard of pure water be achieved. Reverse osmosis systems mainly use membrane filtration technology. Water molecules can then pass through the reverse osmosis membrane. Other ions such as calcium, magnesium, sodium, etc. are discharged with the wastewater. The following are the components of this system.
Dense filter
This filter mainly filters large particles in the water.
A high-pressure pump
Generally, the high-pressure pump we use here is the Southern Special Pump. Provide strong power for reverse osmosis equipment.
Osmosis membrane
Reverse osmosis membrane uses membrane filtration technology. The purpose of purifying water is to allow water molecules to pass through which other ions cannot pass.
Auxiliary systems
For example, ozone sterilization system, light inspection, and filling system. Ultraviolet rays can also be used for sterilization. Ultraviolet rays will not leave any residue. Nowadays, many people abroad like to use ultraviolet rays
