The principle of laboratory ultrapure water machine is to filter through layers of screening and filtration to finally get pure water.
The main technologies used in laboratory ultrapure water machine are as follows:
Pre-treatment: pre-treatment filters usually use coarse filtration and activated carbon adsorption technology, which can remove large particles, suspended solids, algae, colloidal substances and organic matter in the water.
Reverse osmosis: reverse osmosis technology is a semi-permeable membrane will be driven by water pressure to the outside of the membrane molecules diffusion, so as to remove most of the ions and organic matter in the water.
Ion exchange: The water after reverse osmosis is passed through an ion exchange resin to remove ions with low conductivity.
Ultraviolet sterilization: UV sterilization technology, on the other hand, kills microorganisms in the water, including bacteria, viruses and fungi, through ultraviolet irradiation
