What is the difference between ultrapure water equipment and pure water equipment?
In addition to different working principles, there are many differences between ultrapure water equipment and pure water equipment. Next, the editor of Volardda will explain the difference between them.
The difference between ultrapure water equipment and pure water equipment:
One of the differences between ultrapure water equipment and pure water equipment: different uses.
The use of ultrapure water equipment includes the production and cleaning of ultrapure materials and ultrapure reagents, the production of electronic and battery products, and the production and cleaning of semiconductor products.
The use of pure water equipment includes: chemical water treatment in power plants, preparation of food, beverages, drinking water, and drinking pure water from small pure water stations.
Difference The relationship between ultrapure water equipment and pure water equipment is that the conductivity of water is different.
Pure water is industrial pure water, drinking pure water.
What is the difference between pure water equipment and ultrapure water equipment? Literally, there is an extra word "super". "Super" is mainly reflected in three aspects: process flow, electrical conductivity (resistivity) and application field.
What is the difference between pure water equipment and ultrapure water equipment?
First, the process flow is different
A. Pure water equipment: raw water → raw water pressure pump → multi-media filter → activated carbon filter → water softener → precision filter → first-stage reverse osmosis → PH adjustment → intermediate water tank → second-stage reverse osmosis (reverse osmosis membrane The surface is positively charged)→purified water tank→pure water pump→microporous filter→pure water
B. Ultrapure water equipment: pretreatment → reverse osmosis → intermediate water tank → water pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → 0.2 or 0.5μm precision filter → ultrapure water
Second, the conductivity (resistivity) of water is different
A. The conductivity of the water produced by the pure water equipment is between 2-10us/cm, and the water quality generally meets the new version of the "New Standard for Industrial/Drinking Water".
B. The water quality of ultrapure water equipment has relatively strict requirements. Generally, according to the particularity of the industry, ultrapure water equipment with different levels of conductivity such as 12MΩ, 15MΩ, 17MΩ, 18MΩ, and 18.2MΩ are chose.
Third, Different application fields
A. Pure water equipment is mainly used in fine chemicals, daily chemicals, petrochemicals, water-based coatings, biochemicals, wind power, biomass energy, silicon materials, food and beverage, medical equipment, hospitals, pharmaceuticals and other industries.
B. Ultrapure water equipment is mainly used in microelectronics, semiconductors, electronic components, circuit boards, batteries, optoelectronic materials, optoelectronic displays, optical fiber communications, photovoltaics, lighting and other industries.
