Treating over a billion gallons of highly contaminated and varied wastewater sources has enabled us to identify and develop technologies that go beyond looking good in the lab to working effectively and economically at a large, sustainable scale.

Instead of a one-size-fits-all approach, ORION uses several proven technologies that are integrated into mobile treatment units and controlled by a proprietary operating system to provide flexibility and responsiveness to continuously changing water conditions. ORION Water Solution's proprietary automation and telemetry processes makes our systems safer and more effective under challenging conditions in the field, meaning that we can deliver better results for our customers.


Oxidation is used to help precipitate metals and salts, and also acts as a biocide for effective bacteria control. ORION selects an appropriate mix of oxidizing agents depending on the application requirements. Typical oxidizing agents include chlorine dioxide, ozone, hydrogen peroxide, and sodium hypochlorite (bleach). Oxidizing biocides can be more effective, safer to handle, and lower in cost than many non-oxidizing biocides commonly used today.

Suspended Solids Removal

Suspended solids can be removed using chemical and physical separation and filtration methods. ORION uses media filters, inclined plate clarifiers, induced gas floatation, weir tank separation, and ultra filtration to reduce suspended solids to an acceptable level. Selection of the appropriate suspended solids removal system is dependent on both the wastewater characteristics and on the desired quality of the treated water

Anion/Cation Removal

If calcium, magnesium, sulfates, and other metals are a problem, ORION's ion-exchange resins, organoclay, and surfactant modified zeolite can be used to bring contaminant levels into compliance with requirements. ORION Water Solutions has also proven that certain nano filtration elements are very effective at reducing hardness and sulfates in brackish and higher-salinity waters.

Dissolved Solids Removal

Chlorides and dissolved solids up to 150% of sea water salinity are effectively removed using reverse osmosis, a process that ORION has perfected under difficult conditions in Texas oilfields and African refugee camps. In fact, for many applications, no other desalinization technology offers the yield and price performance that ORION's reverse osmosis systems have achieved.

Dissolved Organics Removal

Dissolved organic compounds such as ethanol, methanol, toluene and naphthalene and other water soluble organics can be effectively stripped from wastewater streams through the use of ORION Granular Activated Carbon (GAC) units. Sized to the wastewater content and volume, ORION's modular systems can be rapidly mobilized to strip out dissolve organics down to the sub parts per billion range (pub).


When waste water cannot be efficiently turned into re-usable water, ORION's filter press and centrifuge systems can reduce liquid volumes and cut disposal costs. Dewatering systems can be used in a stand-alone fashion but are commonly used in combination with other treatment steps when solid waste is preferable to liquid waste.
