Voltea, the world’s leader in membrane Capacitive Deionization (CapDI©), has performed a detailed technical analysis supported by field data from various installation sites that compares CapDI technology to that of Reverse Osmosis (RO), now at 2,000 ppm TDS. In the desalination/water purification technology field, CapDI has often competed with RO in all aspects of the business, from capital and operating expenses (including energy consumption and consumables costs), to operational efficiency and water recovery rates. Voltea’s CapDI technology costs have now reached parity with that of RO, and this document details all aforementioned aspects of measure with CapDI consistently at the advantage. We recently released this data at a 500 ppm TDS level, and due to client feedback are able to provide the same data at this higher salinity level.

CapDI vs RO 2000 ppm
If your business uses RO, or if you are considering the purchase of an RO unit, ask yourself if you are satisfied with the expected costs, energy consumption, and predicted water recovery to fully understand the true cost of ownership. By evaluating the attached document, you can see how CapDI dwarfs RO in savings, performance and sustainability, and we would like to challenge you to find a situation where RO is a more desirable and sustainable option subject to similar process conditions.

Voltea, the world’s leader in membrane Capacitive Deionization (CapDI©), recently installed a system on location in Canada, where new governmental regulations on manganese levels in municipal water are being enforced.

Currently, Toronto ground water contains manganese levels in the 150 – 200 parts per billion (ppb) range. These new regulations will enforce that waste water going into municipal water treatment plants cannot have manganese present above 50 ppb. Consequently, ground water removed from construction sites during de-watering for foundation construction must be treated to reduce the manganese levels to below 50 ppb before the water can be sent to municipal sanitary or storm drains.

CapDI was tested to evaluate its efficacy as a chemical-free way to remove manganese below the regulatory requirement level of 50 ppb. The results were a smashing success! Testing that was performed included 3 conditions: 40, 70, and 95% electrical conductivity removal, with the manganese removal as noted:
