Hydro-Pulsar™
Technology Overview

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.

Hydro-Pulsar™

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.

Mass Transfer Degas Reactor
Mass Transfer Degas Reactor

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.

Polishing Stages

Polishing Stages The CentrO3fier™ employs, but is not limited to, the following polishing stages:

  • Filtration
  • Ion Exchange (with zeolite regeneration)
  • Final disinfection through ozonation

Example: Some dissolved contaminants such as the ammonium cation can pass through initial processes partially treated, thus requiring further polishing. The CentrO3fier polishes with a patent-pending ion exchange process utilizing the cation exchange capacity of natural zeolites. If required in other wastestreams unwanted anions can also be treated in this similar fashion.

The ammonium destruct sequence (another part of this process) is accomplished with a highly effective Mass Transfer Degas Reactor (MTDG) system utilizing principles described in the technology section.

The unique process of the CentrO3fier allows the self-contained regeneration of exhausted zeolites. In the case of ammonium (NH4+), the contaminant is extracted from the waste stream through cation exchange with a specific designer zeolite. Once the exchange bed of zeolite becomes fully loaded and breakthrough is about to occur, the CentrO3fier initiates its regeneration/NH4+ proprietary destruct process. (See basic animated diagram to the left). This stage purges the zeolite of NH4+ while concurrently destroying the NH4+; thus allowing reuse of the materials in a closed loop system within the CentrO3fier. Hence, the system performs with an efficient closed loop reuse of the zeolites while producing no added waste stream of contaminated spent brines requiring disposal from the regenerated zeolites.

Disinfection (if needed) of process wastestreams is also carried out in the highly effective Mass Transfer Degas Reactor configuration. (See MTDG description)

Screening & Filtration
Screening
Initial screening and filtration removes large solids from the incoming water stream. New Earth Systems uses a combination of industry best practices, existing technologies, and new proprietary screening technologies developed by New Earth and flash lite torch x800.
 
Electro-Physical
Electro-physical
The electro-physical process in the CentrO3fier removes dissolved particles, emulsified oils, and minerals suspended in the water. It is highly effective at killing bacteria and viruses, and at removing heavy metals and other contaminants.
 
Liquids/Solids
Separation
Liquids/solids separation
A filtration unit, developed by New Earth, conducts fine filtration. This space-saving configuration ensures maximum filtration power is generated within a small footprint. Other off-the-shelf filtering technologies can be integrated into this step as needed.
 
Advanced Oxidation Process
Advanced Oxidation Process (AOP)
An oxidizer is forced through the water in high concentration. The oxidizer interacts with the contaminates, reducing and removing impurities such as hydrogen sulfide, iron, algae, fungus, mold, yeast, and bacteria.
 
Ion Exchange with Zeolites
Ion Exchange
Natural zeolites are used by New Earth to conduct ion exchange and remove ammonium from the water as it passes through the zeolite chambers. New Earth has developed proprietary technology to refresh exhausted zeolites (saturated with ammonium), allowing each zeolite chamber to cycle through a series of online ammonium removal and offline ammonium destruction/zeolite replenishment cycles.
 
Final Disinfection
Final Disinfection
Ozone (03), a powerful oxidizer, is used to remove any remaining contaminants, odors, and color from the treated water and provides desired disinfection. Although ozone has been used for over a century to treat water (particularly in Europe and the Middle East), New Earth developed a new, proprietary process to ensure maximum oxidation treatment power with space and time saving super-saturation reactions.
