Pure water equipment

Pure water equipment mainly uses reverse osmosis membrane technology. Its working principle is to apply a certain pressure to water, allowing water molecules and ionized mineral elements to pass through the reverse osmosis membrane, while the vast majority of inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in water cannot pass through the reverse osmosis membrane, thus strictly separating the purified water that has permeated from the concentrated water that cannot penetrate; The pore size on the reverse osmosis membrane is only 0.0001 micrometers, while the diameter of viruses is generally 0.02-0.4 micrometers, and the diameter of ordinary bacteria is 0.4-1 micrometers.

At present, industrial pure water requires a single-stage reverse osmosis conductivity of ≤ 10us/cm, a bipolar reverse osmosis conductivity of ≤ 3us/cm, and an ultra pure water resistivity of ≥ 10M Ω CM

Ultra pure water equipment adopts pre-treatment, reverse osmosis technology, mixed bed, EDI device, and post-treatment methods to almost completely remove the conductive medium in water, and also remove colloidal substances, gases, and organic matter that do not dissociate from water to a very low level in water treatment equipment. Ultra pure water equipment is also known as: ultra pure water device, ultra pure water machine, ultra pure water instrument, ultra pure water system, laboratory ultra pure water device, etc. The electrical resistivity of the ultrapure water produced by the ultrapure water machine should generally be greater than 10 megaohms, and only water with a resistivity above 10 megaohms is called ultrapure water. Generally, the output of ultrapure water can reach 18.25 megaohms.

Preparation process of ultrapure water equipment

1. Pre treatment system → reverse osmosis system → intermediate water tank → coarse mixing bed → fine mixing bed → pure water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → precision filter → water object (≥ 18M Ω) CM)

2. Pre treatment → reverse osmosis → intermediate water tank → water pump → EDI device → purified water tank → pure water pump → ultraviolet sterilizer → polishing mixed bed → 0.2 or 0.5 μ m precision filter → water object (≥ 18M Ω) CM)

3. Pre treatment → First stage reverse osmosis → Dosing machine (pH adjustment) → Intermediate water tank → Second stage reverse osmosis (positive charge reverse osmosis membrane) → Pure water tank → Pure water pump → EDI device → UV sterilizer → 0.2 or 0.5 μ m precision filter → Water object (≥ 17M Ω) CM)

4. Pre treatment → reverse osmosis → intermediate water tank → water pump → EDI device → pure water tank → pure water pump → ultraviolet sterilizer → 0.2 or 0.5 μ m precision filter → water object (≥ 15M Ω) CM)

5. Pre treatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixing bed → fine mixing bed → ultraviolet sterilizer → precision filter → water object (≥ 15M Ω) CM (Traditional Craftsmanship)
