Title 22 (TOrCsOx®)

Our TOrCsOx® technology has been Title 22 validated by Carollo Engineers and our self-contained systems can be utilized in a variety of applications to treat process water and secondary/tertiary waste water effluent for reuse.

H2O Engineering designed compact, safe and reliable ozone technology that can be skid, trailer mounted or containerized for easy installation and transportation. H2O Engineering’s TOrCsOx® technology can be used in many applications such as iron and manganese oxidation, disinfection, TOC removal, mitigation of trace organic compounds and color/odor removal.



Aeration is the process by which air is circulated through, mixed with or dissolved in water.

Chemical Delivery & Distribution

Chemical delivery & distribution systems are designed to deliver a controlled amount of chemical product to a water source typically by way of pumps, automation and controls.

Color Removal

The poor aesthetic qualities of colored drinking water can be caused by organic compounds and suspended particles. Suspended particles can be removed by filtration and organic compounds can be destroyed through oxidation.

Contaminant Removal

The removal of a chemical or undesirable constituent from a water source.


Water disinfection is the process of neutralization and/or removal of pathogenic microorganisms.

Enhanced UV Treatment

Ultraviolet disinfection technology provides a safe and effective method for destroying most pathogens as a final step in many treatment processes.

Filtration Pre-Treatment

Filtration is often utilized to enhance the operation of many common downstream membrane technologies such as ultrafiltration (UF), nanofiltration, reverse osmosis (RO) and oxidation.

High Purity Water

High purity water is utilized in the manufacturing of pharmaceuticals, semiconductors, and many other products requiring very tight chemical tolerances.

Microorganism Removal

Microorganisms are removed during the disinfection step of a more complex treatment process.

Odor Removal

Oxidants, such as ozone, remove odors in water by destroying compounds, particles and bacterias that cause unpleasant smells.


Oxidation is the process of adding an oxidizer, such as ozone, to a water source in order to remove electrons from the substance or contaminant(s) of interest.

Particulate Removal

The process of removing undesirable suspended solids and biological contaminants from a water source to achieve an acceptable quality of water.

Service and Maintenance

H2O Engineering offers comprehensive service and maintenance contracts for the water treatment industry as well as free technical support for the lifetime of your equipment.

Stringent Biological Discharge Requirements

Due to the varying discharge requirements of local agencies and water scarcity issues facing many areas, wastewater treatment train design is paramount in meeting those requirements while minimizing waste volume.

Suspended Particle Removal

Suspended particles can be removed through a variety of filtration processes to reach the required quality of water.

System Integration

H2O Engineering specializes in combining complex water treatment subsystems into a single, optimized and robust treatment train.

Taste Removal

Unpleasant tastes found in drinking water can be caused by both organics and inorganics. Both are easily treated by a variety of filtration and oxidation processes.

Water Delivery and Distribution

H2O Engineering can design and implement automated delivery systems including pumps, instrumentation and control systems

“H2O Engineering is a valuable contributor to ongoing research in ozone disinfection and advanced oxidation for non-potable and potable reuse applications. Their ozone technology has been proven for Title 22 applications and we are excited to add them to our treatment toolbox.” Andy Salveson, Carollo Engineers, Inc.
