 Our SAFE-ZONE LOD Products

 Are the 21st Century hybrid of Aqueous Ozone.  "A Liquid Oxygen-Based Disinfectant"


TheNext Generation in Oxidation Technology

Liquid Oxygen-Based water treatment  

Conventional treatment protocols for municipal water and waste water treatment are not able to eliminate biologic growth in filtration systems, on ultraviolet systems, nor within distribution systems. Chemical applications are not able to address the biologic and chemical contaminants in many industrial waste streams. The technology oxidation has not advanced in more than thirty years. SAFE-ZONE LOD   has brought aqueous ozone into the 21st century by mimicking ozone organically in a safer,user friendly formula.   "A Reactive Oxygen Species."  

The Product Idea: SAFE-ZONE LOD 

The "Reactive Oxygen Species that is NSF APPROVEDhas improved the technology of disinfection and oxidation by mimicking nature. Nature utilizes a variety of “reactive oxygen species” (ROS) and utilizing specific minerals and metals to aid in the distribution of ROS and act as catalysts for ROS reactions against microbes and organic contaminants.

.SafeZone LOD advances water treatment technology by translating what nature does into a simple to use liquid formulation. The result is a higher reactive oxygen range, for the management of viruses, bacteria, molds and bio-film that is more than twelve times that of conventional chlorine treatments, it far exceeds peroxides and it provides a residual protection that ozone is not capable of.

One of the most critical concerns in today's world, is the control of organic contaminants, and pathogen populations, in our water supply, distribution systems and waste streams. Reactive oxygen species is one of the most effective methods of protecting against pathogen contamination in the environment. Ozone is a natural form of unstable oxygen (O3 rather than O2). Ozone releases the extra oxygen atom, in the form of a "free radical". These free radicals act somewhat like an unguided missile; hitting the organic target (contaminant, or pathogen), and destroying the target. The free radical function is very different from that usually found in the use of such products like chlorine. Reactive oxygen species does not poison, it actually destroys the target. The "target" cannot become immune to this free radical action.

The use of "mechanically generated” Ozone has existed since 1860’s, for the control of pathogens in potable water systems. For over one hundred and thirty years we have attempted to prefect an inexpensive method of generating Ozone, by mechanical means. Unfortunately, Ozone still remains an expensive capital investment for the average user in need of environmental control and improvement.

  SAFE-ZONE LOD , was developed to act as a liquid form of free radical oxygen; just as Ozone generates free radical oxygen. SAFE-ZONE LOD ,requires no expensive capital investment; only a simple injection into the water stream to be treated; or SAFE-ZONE LOD , may be sprayed onto hard surfaces, no rinse needed, no harmful residue & nontoxic. By applying Safe Zone to the water enables the user to control cross contamination and the spread of pathogens, and/or organics in water or on surfaces (bacterial slime, algae, fungus, etc.) and eliminating the bio-film where the pathogens are embedded  leaving a completely clean surface. All this performance at drinking water standards.

The only residual after the application of SAFE-ZONE LOD , is in the water, or on surfaces, is atomic oxygen and GRAS mineral oxides. No chemicals, or harmful residuals are left to be a concern.

SAFE-ZONE LOD ,  is a unique mixture of minerals and oxygen in liquid form. When SAFE-ZONE LOD  comes in contact with pathogens or organic contaminants, it releases nascent oxygen. This “release as needed” property of SAFE-ZONE LOD , offers a strong downstream residual.  Also can be frozen and as it melts continues to control cross contamination and eliminate bio-film even after it melts.

What is Nascent Oxygen?

Oxygen, as it occurs naturally, is a compound of two atoms of oxygen. Nascent Oxygen refers to making available a single atom of oxygen.

Why Nascent Oxygen?

It provides the highest efficiency of oxidation. Oxidation is an aggressive reaction that dramatically changes the physical properties of a target compound.

Of the many elements that will cause oxidation reactions, nascent oxygen is the most aggressive agent and gives the added bonus of not producing toxic byproducts.

For pathogen control, the amount of nascent oxygen necessary to eliminate pathogens is much less than other oxidants or disinfectants.

Ballast Treatment with SAFE-ZONE PW 3300  Produce Wash

Are you currently using chlorine, chlorine dioxide, gaseous ozone, peracetic acid, menadione/vitamin K (SeaKleen), Uv or a combination of these chemicals to disinfect your ballast water prior to discharge? Would you like a system that eliminates like ozone and generates water and oxygen molecules as by-products while at the same time ELIMINATE THE BIO-FILM where the bacteria, mold and viruses are embedded.  If you have an ozone generator on-board would you like to minimize another shipboard hazard (pure oxygen, ozone gas scrubber and etc)?


 GreenAgri has developed a new disinfectant, PW 3300, as an alternative to chlorine, chlorine dioxide, gaseous ozone. PW 3300 is a mineral oxy-chloride ion that reacts in water to generate reactive oxygen species (ROS) (ie. Peroxides, Singlet oxygen, superanion, and hydroxyl ions). ROS molecules react with any microorganisms killing them immediate. Bacteria, viruses, fungi and related biofilms do not develop a tolerance to ROS. PW 3300, is a broad based oxidant that is NSF approved for use in potable water treatment systems up to 100 mg/l. We use ORP to control our dosage and feed rate. In a study using ORP to measure the oxidant potential, the following data was collected:

                              ORP Level            CFU/100ml

                                +200 mV               300        

                                +300 mV                  36 

                                +400 mV                   3   

                                +600 mV                   ND   


Systems using chemical biocides need to be designed to avoid discharging unwanted concentrations of residual biocide. In addition another issue with systems using chemical biocides is the potential for the production of disinfection by products, such as trihalomethanes and halo-acetic acids. The disinfectant must meet G8 and G9 standards of verifying a method that translates the disinfection level.


Discharge limits for Ballast Water Discharge

In a study conducted in California, using a fresh water sample taken from the Delta Bay (Northern California-Sacramento River), we found the microorganism levels (mpn/100 ml) were: 2500+ CFU/100 ml, and E.coli was >4+. Using 10 mg/1 of Safe Zone PW 3300, we were able to reduce the microbiological count (mpn) to: ND/100 ml and non-detect on E.coli in less than 20 minutes of contact time. We also observed an overall improvement in the treatment system. Raw water turbidity was 5.0 NTU and in the settling zone before filtration (using  Safe Zone PW 3300) the turbidity was 0.125 NTU. Before the plant trial, the average turbidity in the settled water was 1.3 NTU. The operator wanted to maintain a free chlorine residual of 0.8 mg/l to 1.2 mg/l. He found that on initial startup, the free chlorine residual dropped slightly because of the removal of the biofilm in the system but returned after several hours. The net results was an overall improved treatment program with non-detect microorganism and a very low free chlorine residual in the ballast water.

Organo-Clay Coagulants & Flocculants

 Why Organo-Clay?

 Have you ever had to wastewater stream that took a lot of coagulant and the finish treatment was still loaded with colloidal particles? Did you have to use a high dosage of a coagulant and still got poor results? Did you ever have a wastewater that was just hard to treat with conventional technology?


Consider using a new innovative technology that incorporates a product that has: 1) high surface area, 2) good charge neutralizing capabilities, 3) good absorption-isothermic, 4) easy to dewater and 5) binds the contaminant preventing leaching.


SZ 1000 series coagulants and flocculants offer a new approach to that “hard to treat” wastewater. The Organo-clay technology works well in high pH and low pH environments, in varying solids loading, and changes in charge demand.


In an oil field production site, SZ 1000 series was used to break the emulsion and capture solids creating a very tight rag layer that was easy to dewater. At this site, tankers would bring is 100 barrel loads of production water which contained varying amounts of free oil, dirt and drilling debris. Each truckload would vary in type and concentration in the wastewater phase. However, using JC 800, we were able to customize each treatment without affecting the dewatering process. The treated water was clean enough for down hole disposal.


In a coal-fired power plant, the wastewater from the wet scrubber contained varying amounts of flyash that had a high pH. The pH was too high for conventional coagulation with inorganic or organic. However, a specially blended Organo-clay coagulant generated a quick settling floc with excellent clarity. The solids dewatered easily and passed the paint filter test for leachate. A side benefit of using the organo-clay coagulant was binding the flyash to prevent airborne contamination from storing flyash.


In industrial applications where CIP (cleaning in place) occurs, the wastewater stream will vary in concentration. It will contain surfactants, dispersants, chlorinated disinfectant, non-chlorinated disinfectants and suspended solids. The Organo-clay chemical will absorb the surfactants and dispersants to neutralize them. The bulk density of the organo-clay provides a nuclear site for mechanical bridging and floc formation/growth to occur quickly. The results are: 1) excellent clarity, 2) lower BOD/COD, 3) lower TSS, 4) lower FOG and 5) low cost treatment per 1000 gal treated.


The applications are endless. If you have a wastewater that seems to defy your best efforts, give us a call and let our engineering staff review your system and offer you an alternative treatment program.
