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 hot
water. 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.)

Flush water to drain with non-scaling water at low pressure, maintaining low
permeate rates.
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.
Introduce hot water to the circulating system to increase the temperature to
175–185°F (80–85°C).
Maintain this temperature and a TMP less than 25 psig (1.7 Bar) for 80 minutes.
Allow the circulating system to cool to 113°F (45°C).
The maximum temperature increase or decrease is 2° C/minute.
Flush to drain with clean water maintaining a TMP of <25 psi and a maximum feed
pressure of 45 psi ( 3 bar).
Factory pre-conditioned HSRO elements are available. Contact Toray for details.
