Purified Water Equipment for Facial Mask Factory Manufacturers

Purified water systems and purified water distribution systems are mandatory inspection items in the technical review of medical mask product registration, so we must perfect the pure water system and design according to the 2015 Pharmacopoeia GMP guidelines. If the water purified system or purified water distribution system does not meet the necessary standards, extensive corrective work may be required at a later stage.

How to produce purified water that meets Pharmacopoeia GMP standards and use it in a mask factory? We give you the answer in this article.

1. What is Purified Water (Pharmacopoeia Water)Mean?

Ordinary water contains various ions, such as chloride ions, sodium ions, calcium and magnesium ions, etc. Purified water can be obtained from daily drinking water through distillation, ion exchange, reverse osmosis, and other water treatment processes. Purified water can be obtained by removing colloids, suspended solids, ions, microorganisms, and other substances in the water through pure water treatment equipment.

In the biopharmaceutical and pharmaceutical industries, companies using purified water equipment, such as mask factories, must strictly follow the purified water indicators specified in the pharmacopeia for process design and installation. In addition, companies also need to verify in accordance with GMP certification requirements.

The following table lists the explicit limits specified by the European Pharmacopoeia (Ph.Eur.), the United States Pharmacopoeia (USP), and the Chinese Pharmacopoeia (CP) for water quality at the point of use.

United States Pharmacopeia European Pharmacopoeia Chinese Pharmacopoeia
TOC ppm C ≤ 0.50 ≤ 0.50 Same as European Pharmacopoeia
Conductivity µS/cm ≤ 1.3 (25°C) ≤ 4.3 (20°C) Same as European Pharmacopoeia
Nitrate (NO3) ≤ 0.2 ppm ≤ 0.000006%
heavy metal ≤ 0.1 ppm lead ≤ 0.00001%
Aerobic bacteria CFU/ml ≤ 100 ≤ 100 Same as European Pharmacopoeia

2. How Does Water Purification Work?

The water purification system is roughly divided into 4 steps: pretreatment (primary purification), reverse osmosis (to produce pure water), ion exchange (to produce 18.2MΩ.cm ultrapure water), and terminal treatment (to produce ultrapure water that meets special requirements Ultra-pure water).

The pretreatment system usually consists of a sand filter, activated carbon filter, softened water filter and precision filter. When the raw water passes through the water filtration system, large particulate matter, residual chlorine and mineral ions in the water are removed, reducing damage to the reverse osmosis membrane and maximizing the role of the reverse osmosis equipment.

Reverse Osmosis System

Reverse osmosis can remove 90%-99% of pollutants and has high purification efficiency. Reverse osmosis membranes have extremely small pore sizes that allow only water to pass through.
The pretreated water enters the reverse osmosis equipment through a high-pressure pump. Water molecules are forced through the semipermeable membrane to the low-concentration side and filter out various soluble salts. thereby obtaining purified water.

Ion Exchange System

Deionized water usually means that the outlet water resistivity reaches 18.2MΩ at 25°C. cm of ultrapure water.
Removing ions through ion exchange system can theoretically remove almost all ionic substances. The principle of ion exchange is to replace unnecessary positive and negative ions in the water with H+ and OH- in the ion exchange resin, thereby achieving the purpose of purifying water.

With the development of technology, electrodeionization systems are gradually used in more fields. Purified water produced through the two-pass reverse osmosis (RO + RO ) + electrodeionization (EDI) process can meet the high-quality water needs of the pharmaceutical and pharmaceutical industry.

Terminal Handling

Usually, engineers will add other water treatment equipment at the end of the system to meet the customer’s special requirements. For example, ultrafiltration is used to remove heat sources, ultraviolet sterilizers are used to reduce total organic carbon (TOC) in water, microfiltration systems are used to remove bacteria, etc. to further produce ultra-low organic, sterile, pyrogen-free ultrapure water.

3. What are the Requirements for Purified Water in Mask Factories?

The medical purified water equipment in the mask workshop complies with the 2015 edition of the Pharmacopoeia GMP certification standard. The essential equipment for the production workshop of disposable medical masks and protective clothing – the two-pass reverse osmosis purified water equipment, from the water quality requirements, material requirements, and pipeline distribution, to ensure compliance with Certification standards.

According to the “Guiding Principles for Technical Review of Medical Mask Product Registration” issued by the National Bureau, based on the intended use and scope of application of the product, it is generally divided into medical protective masks, medical surgical masks, and disposable medical masks.
