The electro-chemical removal of inorganics from waste water. |
|
Enpar Technologies has spent 15 years and millions of dollars in developing a technology which is just now ready for the marketplace. The effective and affordable removal of inorganic wastes from our water streams is becoming an ever more important concept in society. Traditional waste treatment solutions for ammonia and nitrates can require very large capital investments in infrastructure. These systems are based on microbial action that is temperature sensitive (i.e. it does not work under 10 C). Essentially it is expensive and ineffective in cold climates.

Enpar is an electrochemical process based on Capacitive De-ionization (CDI). CDI electrochemically removes ions from waste water and leachates. The waste water stream flows between two electrodes that attract oppositely charged ions. The ions are electrosorbed onto the electrodes, removing them from the process stream, and the deionization cycle continues until the electrodes are saturated with ions. Then, during the regeneration cycle, the two electrodes are discharged or the polarity of the electrodes is reversed. This releases the ions into a separate waste stream, which has a much higher concentration. This residual is then treated elsewhere. The major market advantage that Enpar has over competing technologies is its ability to remove a wide range of ionic contaminants with high recovery rates and do so a lower temperatures. Enpar is able to remove nearly all ionic contaminants – sulphates, nitrates, iron, arsenic and fluorides, along with sodium, calcium and magnesium salts. Pharmaceuticals, neonicotinoids etc. are all removed For example ammonia and nitrates can be internally, directly converted to atmospheric nitrogen, regardless of the temperature. It does so at remarkably low operating costs. Enpar has a much higher water recovery than all other technologies.
