Ceramic Membranes & Separators

Pharmaceutical Water Purification Systems

Overview

Water used in production processes for medical devices and pharmaceutical products must meet stringent standards. The pharmaceutical (medical/pharmaceutical) water systems from NGK Insulators, Ltd. provides safe, high-quality water to meet your needs through an optimal combination of membrane separation technologies. Additionally, our wealth of experience ensures that our systems are highly reliable and economical for any use from purified water to injection water.

Pharmaceutical Water Purification Systems

Purified Water (Ion Exchange Water)

NGK Insulators, Ltd. provides optimum water purification systems to meet the characteristics of different types of input (raw) water via a combination of technologies, such as pre-processing using reverse osmosis (RO) membranes, continuous regeneration ion exchange, and the conventional ion exchange resin method.

Total Systems for Medical/Pharmaceutical Water

To realize reliable, safe, and high-quality conditioning water and pyrogen-free water, each piece of the equipment as well as the whole water purification system must be appropriately designed and manufactured. Membrane filtration equipment and distilling equipment should operate safely on their own. However, system components, including reservoirs, heat exchangers, and piping, can be combined with the appropriate sterilization system to reliably supply the desired water quality.

NGK Insulators, Ltd.'s comprehensive solutions can meet your demand for water to protect people's health.
