Puretech - Model GENESYS -Purified Water Systems

Purified and highly purified water applications

Purified water is used as an excipient in the preparation of non sterile products and as a starting material in the preparation of water for injection and pure steam. It’s also used for rinsing purposes and in the preparation of cleaning solutions. Highly Purified water is used in the preparation of medicinal products where bacterial endotoxins need to be controlled, except where water for injection is required.

Operating principle 

The pretreated (softened) water is passed through a filter housing (typically 5 µm) and analysed for free Chlorine prior to entering the RO feed tank. The filtered water then enters the stainless storage tank, if the tank is full the softened water is returned to the raw water tank to ensure constant movement to minimise the risk of bacterial proliferation. The softened water is then pumped at high pressure using a stainless steel multistage centrifugal pump, through the RO membranes. The RO permeate is then fed through a membrane degasser to remove dissolved Carbon Dioxide, followed by a CEDI unit in order to remove ionic contaminants. The purified water is then passed through a UV irradiator unit before being fed to the storage vessel.

Control system

The GENESYS™ utilises the latest technology with touch screen HMI to allow ease of operation and monitoring. The GENESYS™ allows control and monitoring from a single interface with data logging facilities and links to user systems eg, BMS, DCS or SCADA. The GENESYS™ control system has the flexibility to operate complete turnkey packages allowing customers to reduce costs and simplify operation using a single access interface for pre-treatment, purification, storage and distribution. The GENESYS™ control system ensures safe operation, protecting the system and the operator, giving you confidence and peace of mind.

Trusted technology, safely implemented

The GENESYS™ Purified Water System is designed to generate Purified water in accordance with the International Pharmacopoeial specifications for Purified or Highly Purified water. The system has been designed to allow automatic hot water sanitisation of the complete unit including the pipework feeding the Purified water into the storage vessel. The GENESYS™ units utilizes the following major components within a fully protected skid so that the system can be kept clean and prevent any injuries to operators during sanitisation.

Key components

Softened water tank

This 316L stainless vessel is used as a reservoir for sanitisation and can be used for the automatic CIP cycles.

Reverse osmosis

RO technology involves using a variable speed pressure pump to force a portion of the feed water through semi-permeable membranes. The permeate flow is kept constant, independent of variables such as the feed water temperature.

Continuous electro deionisation

The water passing through the CEDI is deionised to Purified Water using an electric current. The concentrate water exiting the CEDI unit is reused and mixed with the RO feed water.

Ultraviolet irradiation/ultrafiltration

The pure water exiting the CEDI passes to a UV unit or a 6,000 NMWL Ultrafilter to give added security in achieving the Purified and Highly Purified water specifications.
