Ultrapure water equipment: laboratory water purification system

Equipos de agua ultrapura para laboratorio is specially used to provide high-purity water for laboratories. It removes impurities, ions, microorganisms, organic matter, etc. in water through a series of water treatment processes to ensure that the water quality meets the experimental requirements.

Equipment composition and working principle

Pretreatment unit:

Filter: removes large particles of impurities (such as sand, soil, etc.) in the water.

Activated carbon filter: adsorbs chlorine, organic matter and other soluble pollutants in the water to protect subsequent equipment.

Reverse osmosis system: removes most of the dissolved salts, heavy metals, microorganisms and bacteria in the water through the reverse osmosis membrane. The ultrapure water reverse osmosis system is one of the core parts of the equipment, which can significantly reduce the conductivity of water.

Deionization resin: Ion exchange technology is used to further remove the remaining ions (such as sodium, calcium, chlorine, etc.) in the water. DI resin exchanges the positive and negative ions in the water with the ions on the resin to produce pure water.

Ultrafiltration: Use finer membrane filters to further remove tiny particles, bacteria, colloids, etc. to ensure the microbial purity of the water.

UV disinfection: UV light irradiates the water flow to prevent microbial reproduction by destroying the DNA of microorganisms and ensure the sterility of the water.

Conductivity monitor: Monitors the conductivity of water to ensure that the purity of the water meets the requirements. The lower the conductivity, the fewer impurities in the water and the higher the purity.

Water storage system: Used to store treated ultrapure water. The water storage tank is usually made of materials that do not contain organic matter to avoid water contamination.

Monitoring and alarm system: detects water quality and equipment operating status, and promptly alarms to remind users to replace filter elements, resins, etc., to ensure the continuous and efficient operation of the system.

Ultrapure water equipment water supply type:

Deionized water: ions (such as sodium, calcium, magnesium, etc.) in water are removed through the ion exchange process, and are often used for general laboratory purposes. It can remove most dissolved salts and organic matter, but is not suitable for experiments with extremely high water quality requirements.

Ultrapure water: After further treatment of deionized water (such as reverse osmosis, ultraviolet irradiation, activated carbon filtration, etc.), almost all dissolved substances, including trace amounts of organic matter and bacteria, are removed. It is usually used for experiments with extremely high water quality requirements, such as high-precision analysis, instrument cleaning, etc.

Distilled water: Impurities and dissolved substances in water are removed through the distillation process. It is suitable for some experiments with lower requirements for water purity, but some volatile substances in the water may still be distilled out.

Reverse osmosis water: Most dissolved substances in water, including bacteria, heavy metals, salts, etc., are filtered through a reverse osmosis membrane. The water quality of RO water is between deionized water and distilled water, and it is suitable for some experiments that do not require ultrapure water.

The purity requirements for water in laboratories are usually high, especially in the fields of chemical analysis, instrument use, cell culture, etc. Ultrapure water purification equipment can provide water quality with a conductivity of up to 0.1 µS/cm or even lower.
