A full CentrO3fier™ system is a combination of six modules — a synthesis of filtration, electrocoagulation, advanced REDOX (reduction/oxidation) processes disinfection, and ion exchange technologies. It’s a technological collection in one complete, powerful system. The following is a highlight of a few of the technologies employed.
The Hydro-Pulsar™ (HP) employs a dynamically advanced, new patent-pending electrocoagulation technology. Although New Earth’s specific technology (which utilizes a broad band approach to contaminate removal) is quite complex, the basic principles of electrocoagulation (EC) are really quite straightforward. Simply put, EC utilizes voltage and electric current to initiate reactions*, coagulate, and stabilize wastestream contaminants. Through coagulation, smaller colloidal particles are grouped into larger, denser particles. With greater density and size, these particles are easier to remove or filter from wastestreams.
Electrocoagulation is conducted by introducing an electrical current and voltage to the contaminated water. The current slowly dissolves consumable electrodes to introduce coagulating metal ions. “The electrolytic addition of these ions has a number of advantages over their addition chemically. There is no addition of anions meaning no increase in salinity of the treated water. The system produces half to one-third of the sludge. Greater [re]activity means less metal ions required and a wider range of pollutants can be removed.” 1
These metal ions coupled with the other synergistic effects of the technology can drive the contaminants to their most stable state, often eliminating the initial toxicity and enabling the residual solids to pass EPA leachability tests. New Earth also has many other enhancements to the old EC concept which will set our patent-pending technology as a benchmark for future industry standards. Some applications can also use non-consumable electrodes.
Electrocoagulation is especially effective when combined with other CentrO3fier technologies including our advanced REDOX (Reduction/Oxidation) process and ion exchange (IX) systems. Through our Hydro-Pulsar™ process electrocoagulation technique, the wastestream is cleansed of the majority of its initial contaminants, thus making ion exchange and other downstream processes more effective and less costly. That’s one of the great strengths of the CentrO3fier — the proper and measured combinations of technologies working in balance to effectively and cost efficiently clean your wastestream.
*Other treatment scenarios include: osmotic pressure changes enhancing cellular destruction and enhanced sludge dewatering, pathogen kill, REDOX reactions with off gas production, precipitation, pH swings towards neutral; dye color bleaching … the list goes on.

The CentrO3fier’s Mass Transfer Degas Reactor (MTDG) is an efficient, compact, patent-pending configuration of cross-bundled technology. Its component design provides the ideal environment to enable the mixing, the contact time, and the waste gas extraction necessary to achieve desired treatment reactions.
In the MTDG, waste slurry is initially sent through a pipe reactor where liquid and/or gasses are injected through an efficient hydrodynamic concept and diffuser. This optimizes initial mixing conditions.
Following this stage, sufficient contact time and turbulence is provided in an energy efficient geometry, allowing the desired reactive conditions to proceed. As gasses are used up or reacted (such as with O3 injection), it is usually necessary to remove spent gas and reinject fresh gas. Such processes ensure the most reactive state will prevail within the reactor.
With the CentrO3fier’s MTDG system, this occurs through a special gas/foam collection configuration which continuously extracts excess or spent gas. Concurrently, foam/solids are filtered and liquid is reinjected back into the MTDG process. All of this transpires with no moving parts…just effective geometry and the application of sound engineering principles.
Whether your need is to provide an oxidation or a reduction environment. Whether your requirements are to inject polymers or other chemicals. If you are striving to optimize any process which requires liquid/liquid or liquid/gas contact; the MTDG Reactor excels. Its design provides the dynamic means of solution injection, mixing, mass transfer, and contact time. The MTDG controls the degas/foam/solids balance necessary for your custom reactions to not only efficiently take place but continue to an effective completion.
