Heat Sanitizable Membrane

For applications requiring hot water sanitization eliminating
sanitization by chemicals.
Toray’s Heat Sanitizable RO membrane elements provide superior permeate quality
for hygienic purified water applications. RO elements use a cross-linked fully aromaticpolyamide composite membrane.

Heat Sanitization

Conditioning procedure:

Toray HSRO-series elements are sanitized with hotwater as the preferred method in food andpharmaceutical applications eliminating the need forchemicals and other disposals.
New Toray HSRO-series elements must be preconditioned prior to initial use by exposure to hotwater. Conditioning water must be high-quality
chlorine and oxidant free non-scaling, non-foulingwater. RO permeate is preferred (Water from an RO
that has been in operation for at least 24 hours)

1.

Flush water to drain with non-scaling water at low pressure, maintaining low permeate
rates.

2.

Recycle warm water 40–45°C at less than 25 psig (1.7 bar) trans-membrane pressure(TMP). The maximum differential pressure is 2 psi per element or 10 psi per vessel.

3.

Introduce hot water to the circulating system to increase the temperature to 175–185°F(80–85°C).

4.

Maintain this temperature and a TMP less than 25 psig (1.7 Bar) for 80 minutes.

5.

Allow the circulating system to cool to 113°F (45°C).

6.

The maximum temperature increase or decrease is 2° C/minute.

7.

Flush to drain with clean water maintaining a TMP of <25 psi and a maximum feed
pressure of 45 psi ( 3 bar).

8.

Factory pre-conditioned HSRO elements are available. Contact Toray for details.

NOTICE
1.

Elements are preserved in sodium meta-bisulfite. Appropriate personal
protective equipment should be worn when handling.
