Setting the Record Straight on Algae Separation hen different technology enters a market, there is always some question about how it compares to what’s been available. That’s the case with spiral plate versus disc stack separating equipment. Disc stack separation has a proven 50-year record in algae dewatering and concentration. With over 300 installations worldwide, the process has been perfected and a significant amount of data collected.
3. G-forces over 10,000 allow for production of pastes that are 11.5% drier.

4. Processing parameters such as speed and ejection time are adjustable on disc stack equipment. This allows production of solids with varying dry matter levels for different customer requirements.
Design elements in disc stack machines allow production of a superior product at a lower cost. Here are the facts: 1. Continuous machine operation allows for maximum up-time during processing. Solids are ejected at regular intervals with absolutely no interruption. There is no need to slow down the equipment and then bring it up to operating speed with a disc stack separator. 2. Automatic cleaning-in-place (CIP) is programmed in the machine, saving time and labor costs.
With six service offices throughout North America and professionals that are experts in algae separation, GEA Westfalia Separator offers the centrifugal separation equipment that can cost-effectively meet your needs. We welcome the comparison between the two separation technologies. To learn more and find out about testing one of our machines, contact Keith Funsch at 201-784-4322 or Keith.Funsch@gea.com.
5. Thirty (30) models are available with capacities ranging from less than 1 m3/hr to over 150 m3/hr. We work with you to find the machine that maximizes production for your current operation. Most machines can be scaled up as needs change. 6. Energy consumption, given the complete range of disc stack machines we offer, is equal to or less than what spiral plate technology offers. Disc stack machines use up to 20% less power.
