VinoCon RO5

Summary

Product identification

The VinoCon RO5 Series consists of proprietary thin-film reverse osmosis (RO) membrane elements characterized by high sodium chloride (NaCl) rejection. These elements achieve an average rejection of 99.2% on 2,000 ppm NaCl at 25°C and 225 psi operating pressure.

VinoCon RO5 elements provide high flux rates at operating pressures up to 1,200 psi (8,274 kPa) and are designed for periodic hot-water sanitation while maintaining element integrity.

Primary applications include:

• Concentrating grape juice from harvested grapes, requiring stringent sanitary procedures.
• Wine must concentration.
• Wine adjustment and concentration.

Key features include a Durasan* Cage patented outer wrap, standard feed spacers, and polysulfone parts.

Compliance:

• FDA Regulations relevant sections of 21CFR
• EU Framework 1935/2004/EC

Operating limits

• Typical Operating Pressure: 200-800 psi (1,379 – 5,516 kPa)
• Maximum Operating Pressure: 1,200 psi (8,274 kPa)
• Maximum Temperature: 122°F (50°C)
• Sanitization Temperature: 194°F (90°C)
• pH Range: 3.0-10.0
• Maximum Pressure Drop:
  • Over an element: 15 psi (103kPa)
  • Per housing: 60 psi (414 kPa)
• Chlorine Tolerance: 500 ppm-hours (dechlorination recommended)
• Operating pressure in bar multiplied by operating temperature in degree Celsius should not exceed 2000.

Product water

• Sodium Chloride Rejection: Average 99.2% (at 2,000 ppm NaCl, 25°C, 225 psi)
• Typical Operating Flux: 5-20 GFD (8–34 LMH)
• Clean Water Flux (CWF): 16-18 GFD (27–31LMH) @ 425 psi. CWF is the rate of water permeability through the membrane after cleaning (CIP) at reproducible temperature and pressure.

Mechanical / hydraulic

The VinoCon RO5 elements utilize a Thin-film membrane (TFM*).

Cleaning-in-Place (CIP) Limits

Hot Water Sanitization Recommendations

• Prior to first use, new elements must be flushed with clean water for at least an hour, at a transmembrane pressure of not more than 45 psi (3 bar), to remove residual chemicals.
• The system must be started and in operation for a minimum of 24 hours prior to hot water sanitization.
• If new elements are to be hot water sanitized before first use, the system must be flushed at a low transmembrane pressure (up to 45 psi (3 bar)) for a minimum of 24 hours prior to sanitization.
• Transmembrane pressure during hot water sanitization should be maintained as low as possible, not exceeding 45 psi (3 bar), while ensuring some permeate flow for effective sanitization on the permeate side.
• The cross flow to the system should be monitored and adjusted so that the pressure drop is not more than 2 psi per element or 10 psi per housing.

Hot Water Sanitization Procedure:

1. Elements that have been in operation should be cleaned with an approved Clean In Place (CIP) procedure to remove any mineral scales or organic foulants, and then thoroughly flushed for at least an hour before sanitization.
2. Increase the temperature in the system from room temperature to the target sanitization temperature (up to 90°C/194°F) at a rate not higher than 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 higher than 5°C/9°F per minute.

Loss of Permeate Flow After Repeated 90°C Sanitization Cycles: Between 30% and 50% of the original permeate flow rate was lost before the element performance stabilized after repeated heat treatments in a controlled environment with deionized water. Over 90% of this flow reduction occurred during the first heat treatment. With the loss of permeate flow rate, salt rejection increases. The rate of cooling and heating was not more than 5°C per minute, and the differential pressure drop per element did not exceed 2 psi.
