- But can filtration be done more sanitary with lower
energy consumption?
- SANI Membranes have created a more sanitary and
energy efficient solution
- The Hollow Plate™ technology
SANI Membranes 3
WHY chose The Hollow Plate™ Technology??
The Hollow Plate™ technology delivers several benefits:
• Reduces energy consumption by 30-50%
• Sets new sanitary standards - improving cleanability and inspection
• Sharper cut-off and optimal flux on all membrane area
• Very low and uniform TMP - leading to new MF and UF opportunities
• Higher concentration, viscosity and solids load

Unique Operation key features of the Hollow Plate™ Module:
• Free Flow – 1.7mm membrane to membrane distance
• Energy efficient – minimized pressure loss reduces energy consumption by 30-50%
• Very uniform TMP throughout the system – sharper cut-off
• Can handle very difficult feeds with high viscosity, high solids loading etc.
• 100% Drainable – no product loss
> Energy efficient, higher concentration, sharper cut-off
The Hollow Plate™ Technology
Unique Sanitary key features of the Hollow Plate™ Module:
• Open and Clean design – Sanitary
• No feed or permeate spacers – Sanitary
• No flow dead areas - Sanitary
• 100% Drainable - faster CIP, reduced water & chemical consumption
• Permeate side can be CIP cleaned
> Shorter cleaning time, less water & chemicals

”Novozymes is consciously working on reducing energy consumption in our production processes.
It was here possible to achieve very clear reduction in energy consumption compared to current
membrane filtration process” Sune Jakobsen, Senior Manager R&D, Novozymes A/S
“It seems possible to achieve significant reduction of energy consumption and perhaps even
simultaneously achieving improved filtration process that could eventually lead to new products”Niels Ottosen, Senior Food Scientist, Research and Development, Arla Foods Ingredients Group P/S
