Ultra-Violet [UV] Water Sterilizers

Ultra-Violet [UV] is a very effective method of sterilizing water for Drinking, Cooking & Other Uses. Advantages include: Very low capital cost.  Near-zero operating costs.  Effective sterilization without any change to the taste or other properties of the water. Other fluids can also be sterilized by UV.

Ultra-Violet Light waves effectively kill bacteria and viruses when given in sufficient dosages. Producing the UV light requires a special lamp containing selected gases that are excited by the flow of electricity through them, emitting UV Light.  Usually, the UV Lamps are contained in quartz sleeves, or the fluid may pass through a quartz sleeve.  Often, reflectors may be added to maximize the effectiveness of the UV Rays.  The UV Dosage is calculated to eliminate the pathogens in the contaminated water, and is measured in microwatts per square centimeter.

Ozone Water Sterilizers

On-Demand Ozonated Water Systems

Ozone Water Sterilizers are a very effective method of sterilizing water for drinking and other uses. Ozone is the only approved method of sterilization for water bottling in most jurisdictions.  Advantages include: Continuing sterilization after treatment.  Modest operating costs.  Effective sterilization without adding any unpleasant taste to the water. In fact, ozone sterilizers generally enhance the taste of the treated water.

Ozone molecules contain three oxygen atoms [O3] while oxygen molecules found in the atmosphere contain two oxygen atoms [O2].  The properties of the two types of oxygen molecules are quite different.

Ozone is a very potent oxidizer, and as such is effective in pathogen destruction. As the ozone attacks pathogens, it breaks down into O2 molecules. Since ozone has a half-life, it continues gradually breaking down into O2 leaving additional dissolved oxygen in the water.  Dissolved oxygen is the most important component of good drinking water taste, so such increase in dissolved oxygen enhances the taste of the water.


In addition to Water Purification & Bottled Water Plants, there are many other uses of Ozonated Water to include:

  • ·        Hand Washing & Sanitizing
  • ·        Meat, Poultry & Seafood Processing
  • ·        Hospitals
  • ·        Nursing Homes

Gray Water Recycling Systems

Gray Water Recycling Systems [GWRS] are specifically engineered to treat waste water from Showers, Sinks, Dish Washers, Laundry Washing Machines and Other Non-Sewage Drainage Sources in Apartment Buildings, Hotels & Commercial Buildings and prepare it for re-use for All Purposes -- except Drinking & Cooking.

These systems typically provide for re-use of about 85-90% of the Used Gray Water normally discharged down the drain.  This saves dramatically on water usage and eliminates most of the waste water loss, which is of increasing importance in localities where water is in critically short supply.

GWRS systems are designed with several technologies that provide synergism by working in concert together.  These technologies include various types of Filtration, Sterilization & Appropriate Membrane Technology.  Activated Carbon Absorption is usually applied as an essential part of the system.

Wash Water Recyclers for Steam Cleaners & Pressure Washers

Wash Water Recyclers offer the ultimate in Efficiency, Reliability & Quality.  Used wash water is recycled using a compact, self-contained, multi-stage state-of-the-art water treatment system.  A Flocculant Injection System is used to aid in the removal of suspended solids that can cause excessive filter replacement costs.  This disinfectant is non-toxic and acts to collect smaller particles together into clusters for easy removal by subsequent system components.

The water next enters the Oil & Solids Separator where oil and grease are mechanically separated from the water for skimming while solids collect at the tank bottom and flow to the Solids Collection Tank.  An Automatic Oil Skimmer separates and removes oil [along with some water] to an Oil Collection Tank.  Re-Cycled Wash Water is collected in a Holding Tank to provide a continuous supply of clean water for washing again – and again – and again.

Glycol Recycling Systems

Standard GRS-M systems include models that produce 2, 4, 5, 7, 9, 12 & 15 U.S. Gallons Per Minute [GPM] of High Quality Re-Cycled Glycol/Water Mixture that can be used again as Engine Anti-Freeze and Coolant.  Custom models can be manufactured to produce any capacity desired in a variety of Fluid Re-Cycling Applications.

Membrane-Based Anti-Freeze Recyclers [GRS-M] are very effective in producing high quality product with Reduced Chlorides & Lowered Total Dissolved Solvents [TDS] as required for commercial applications.  Membrane based systems remove all or nearly all color, all oils, 99% or higher of heavy metals, and all or nearly all suspended solids.

Glycol sources with high oil content should be pre-treated prior to treatment by membrane-based systems.  In addition to Membrane-Based Reverse Osmosis (RO) systems, we also offer Filtration Type Anti-Freeze Recycling Systems.

Wastewater & Sewage Treatment

Wastewater & Sewage Treatment is the process that removes the majority of contaminants from Wastewater & Sewage to produce both a Liquid Effluent & Sludge.  Conventional Treatment of Wastewater & Sewage in a Normal Activate Sludge System includes Primary Aeration & Settlement of the Incoming Liquids & Sewage, followed by Final Settlement of the Sludge and Bio-Mass.  This type of treatment requires regular removal and discharge of Sludge from the Primary Settlement Tank, as well as removal of Surplus Bio-Mass from the Final Clarifier.

Extended Aeration -- Activate Sludge System

We use an even more effective variation of the Activated Sludge System as a combination of Extended Aeration & Activated Sludge Technology.  Such combination of technologies is ideal for Modular Unit Expansion, offering greater flexibility in the design of the Composite System & Site Lay Out.  The individual units are easy to install, operate and maintain, while it is possible to make considerable upgrades at later stages.

Sewage treatment systems that do not employ Extended Aeration Treatment require continuous draining and disposal of sludge.  In the Extended Aeration Process wastewater passes through a Bar Screen that keeps out any large solids.  A diffuser system introduces air into the aeration chamber.  The air bubbles that are generated provide the oxygen necessary to sustain the bacteria and also provide the agitation necessary to reduce solids to small particles

After a suitable retention time, the solution is displaced from the Aeration Chamber to the Clarifier Chamber.  There any remaining solids settle to the bottom in the form of Activated Sludge that is returned to the Aeration Chamber to maintain a High Active Bacteria Level.  The clear liquid at the top of the Clarifier Chamber flows into the LS3 Wastewater Purification System to kill any disease-carrying bacteria that remain.

The Activated Sludge Process is a biological method of wastewater treatment that is performed by a Variable & Mixed Community of Micro-Organisms in an Aerobic Bacteria Aquatic Environment. Aerobic Bacteria work much faster than Anaerobic Bacteria.  An Aerobic System injects and circulates air inside the treatment tank.  Such addition of oxygen accelerates and speeds-up the Wastewater and Sewage Treatment Process.

The Bacterial & Other Micro-Organism Cell Mass [Bio-Mass] that is generated by cell reproduction is separated from the liquid being treated prior to discharge, collected and mixed with incoming sewage.  Such Bio-Mass Recycling increases the rate of decomposition of the solid waste coming into the system since such incoming sewage almost immediately comes in direct contact with a hungry relatively-dense population of bacteria.  This is called the Activated Sludge Process.

All of the incoming sewage is food for the Cell Mass -- generating Cell Activity & Reproduction in the processes called Respiration & Synthesis. The Extended Aeration -- Activate Sludge System totally destroys and eliminates all solid waste products and then recycles the clean effluent for reuse in Vehicle & Equipment Washing, Fire Protection, Irrigation of Golf Courses, Trees, Shrubs, Ground Cover & Flower Beds and Other Non-Potable Uses.

The normal processing time for an Extended Aeration System is 24 hours to produce High Quality Effluent that after chlorination meets purity standards to be discharged into a ground aquifer.  By comparison, our Extended Aeration -- Activate Sludge System is twice as efficient so the total processing time is reduced to only 12 hours.  This allows our system to be only half the normal size and at much less cost. 

Instead of a less efficient and more costly system to process 1,000,000 gallons per day [GPD], one of our systems half the size and at much less cost can produce 500,000 gallons in 12 hours or 1,000,000 gallons in 24 hours. The savings in cost can be used to purchase a 1,000,000 GPD Water Recycling & Purification system that can produce Potable Water for Drinking & Cooking from the remediated wastewater.

With the Extended Aeration -- Activate Sludge System:

There is NO SLUDGE to dispose of.

There is NO ODOR.
