Modular and Scalable System Design:

Liberty Hydro combines patented ZVI Blue™ media, Suspended Bed technology (Patent Pending) and modular reactor vessel design to provide a wide range of options to solve your difficult water pollution control needs:

There are no moving parts inside the reactor vessels minimizing maintenance and service requirements. The patented ZVI Blue™ Media inside the vessels will operate across any operating temperature without loss of efficiency.

Depending on your application and site configuration, the Liberty Hydro Modular design can accommodate:

• Series arrangement where a longer hydraulic contact time is necessary, or Parallel arrangement where the required contact time is shorter.
• Upflow design where the pollutant binds to the reagent, or Downflow where there is significant precipitate generated.
• Gravity Fed or Pump Driven
• Manually operated or Automatically controlled via PLC

The dimensions of the reactor vessels are designed to suit the process flow rate. All reactor vessels are sized to fit on a standard over the road truck trailer and may be moved into place by traditional lifting techniques such as forklifts or mobile cranes.

The reactor vessels may be placed on a concrete pad, or similarly prepared, level surface. This approach requires minimal capital investment in foundations or infrastructure. Vessels are fully self-contained, and no site assembly is required. The modular approach provides a great deal of flexibility to scale up or down your treatment process as the process may change, or to relocate the system if site conditions mandate.

The vessels are interconnected via piping or industrial hoses and easily allow vessels to be added, removed or bypassed. All piping and valves are accessible from grade level.

Typical treatment systems will couple the modular reactor vessels with industry standard prefilters, pumps, acid dosing systems, oxidizers, clarifiers and instrumentation.

When using solid reagents to treat pollutants in industrial water treatment systems, the application technology choices have been limited.

A fluidized bed reactor requires long hydraulic resident times to ensure contact and interaction with the reagents. This leads to large scale, capital intensive installations. This technology relies on mixers, blowers or agitators to keep the reagent in circulation, which adds complexity and expense to the system.

A packed bed reactor using solid reagents has a better contact rate between the water and the reagent and hence consumes a smaller footprint. This technology however can limit flow rate and requires a significant amount of pressure to pass through the packed bed. These systems also face challenges with ratholes and bridging of the media or fluid bubbles that can dramatically limit performance.

An ideal solution is one where the reagent has very high contact rates with the water to be treated, have a small footprint, no internal moving parts, low system pressure drop and no risk of bypassing the reagents.

Liberty Hydro’s proprietary Suspended Bed approach (Patent Pending) delivers just such a solution.

Liberty Hydro’s ZVI Blue™ media binds the reagent to the web of an open-celled foam substrate. The media is engineered to maximize reagent density and facilitate handling. The open-celled structure allows water to flow through the media and ensures high contact rates with the reagent at a minimum pressure drop. When placed inside a treatment vessel handling a continuous flow, the depth of media creates a Suspended Bed of reagents with high contact rates and no internal moving parts.

The Suspended Bed approach combines the best features of both Fluidized Bed and Packed Bed technologies while doing so with a compact footprint, minimal capital cost, no internal moving parts. minimal risk of reagent bypass and low system pressure requirements.

It also allows for a modular and scalable system to meet the specific pollutant control, flow rate and site requirements for each application.

Field tests have shown that ZVI Blue™ has attained among the highest levels of pollution control in the industry, Including:

Selenium in FGD Purge Water	Below 10 ppb
Selenium in CCR Pond Drainage	Below 5 ppb
Selenium in Coal mine runoff	Below 5 ppb
Chromium in Nickel Mine Runoff	Below 20 ppb

Liberty Hydro is pleased to release the next generation of our ZVI Blue™ media. This media is now even more effective in removing pollutants from Industrial process and waste waters.

Our new media has demonstrated:

• A 55% improvement in reducing pollutants from waste waters
• More consistent performance characteristics
• Continued ability to meet the most stringent requirements for effluent pollutant levels
• Lower cost
• Industrial scale manufacturing process
• Better thermal management properties (*)

(*) When tested over a range of deactivation and disposal scenarios.

ZVI Blue™ continues to be among to most effective tools for managing pollutants such as Selenium, Chromium, Arsenic and Mercury. This new media, together with Liberty Hydro’s Modular and Scalable system approach will allow greater flexibility in the size, configuration and price of water treatment systems.
