VinoCon RO3

Summary

Product identification

The VinoCon* RO3 Series are proprietary thin-film reverse osmosis (TFM*) membrane elements. They are characterized by high sodium chloride (NaCl) rejection and a smooth, fouling-resistant membrane surface. These elements are designed for high crossflow, daily Clean-In-Place (CIP), and can handle suspended solids and periodic hot-water sanitization while maintaining element integrity.

The VinoCon RO3 Elements feature a Durasan* Cage patented outer wrap, standard feed spacers, and polysulfone parts.

Applications:

• Concentrating grape juice in wineries.
• Wine must concentration.
• Wine concentration and adjustment.

Regulatory Compliance:

• FDA Regulations relevant sections of 21CFR

• pH Range: 3.0-10.0
• Maximum Pressure Drop:
  • Over an element: 15 psi (103 kPa)
  • Per housing: 60 psi (414 kPa)
• Chlorine Tolerance: 500 ppm-hours (dechlorination recommended)

Hot Water Sanitization Recommendations:

Before first use, new elements must be flushed with clean water (RO permeate strongly preferred) for at least an hour at a transmembrane pressure not exceeding 45 psi (3 bar). If hot water sanitization is to occur before first use, the system must be flushed for a minimum of 24 hours prior to sanitization, at a low transmembrane pressure (up to 45 psi / 3 bar).

During hot water sanitization, transmembrane pressure should be kept as low as possible, not exceeding 45 psi (3 bar), while ensuring some permeate flow for effective sanitization. Cross flow should be monitored and adjusted so that the pressure drop is not more than 2 psi per element or 10 psi per housing.

Procedure for Hot Water Sanitization:

1. Elements already in operation should be cleaned with an approved CIP procedure to remove mineral scales or organic foulants, then thoroughly flushed for at least an hour before sanitization.
2. Increase the system temperature from room temperature to the target sanitization temperature (up to 90°C / 194°F) at a rate not exceeding 5°C / 9°F per minute. Maintain the target temperature for 30 to 60 minutes.
3. Cool the system to room temperature at a rate not exceeding 5°C / 9°F per minute.

Permeate Flow Loss after Repeated 90°C Sanitization Cycles:

The percentage of permeate flow rate lost from high temperature sanitizations varies, depending on factors such as temperature ramp rates, presence of other species, feed flow rate, heat transfer rate to the membrane, and the thickness/geometry of the feed spacer.

Under optimum conditions with deionized water in a controlled environment, between 30% and 50% of the original permeate flow rate was lost before performance stabilized after repeated heat treatments (over 90% of this reduction occurred during the first treatment). With permeate flow rate loss, salt rejection tends to increase. Pilot testing based on the noted criteria is recommended to determine the best operating parameters for specific applications.
