Orifice Scrubber is rarely used for absorption. These devices are effective for reactive scrubbing or removing gaseous pollutants that are already very soluble in liquid. They are gas-atomized. Their collection efficiencies range from 80 to 99 percent. A simple orifice scrubber can be operated at increasing energy input. A mathematical model based on eulerian/lagrangian method has been developed to predict particle collection efficiency from a gas stream in an orifice scrubber.

Orthorectification is the process of correcting the imagery for variation in the position of the sensor/platform, for convergence of light, for distortion due to curvature of optical lenses and for irregularity in the terrain. Orthorectification is a form of geometric correction that takes into account the relief of the terrain. Orthorectification involves the removal of distortions introduced into remote sensed imagery caused by changing terrain elevations, sensor location & the earths curvature and requires the availability of a suitable digital terrain model & ground control points.

Oxygen concentrators are molecular sieves that separate nitrogen from oxygen and can usually provide 90-95% oxygen at flows of 4-6 L/min. Humidity can be added to the system by the attachment of a bubble humidifier. These are quiet, produce little heat, and usually weigh no more that 40-60 lb. These also require very little maintenance and are equipped with alarms to warn if the oxygen concentration falls below a critical level.

Pesticide storage cabinets provide needed protection for companies who specialize in lawn care, golf course management, agricultural interests or who handle and store pesticides and poisons. It contains galvanized steel shelves, galvanized steel leveling legs and internal & external welded steel double wall panel.

Pillow tanks are collapsible, flexible storage tanks that provide temporary as well as long term liquid storage. These are useful for oil spill recovery operations, bulk liquid transport, storage of bilge slops, potable water, chemicals, or fuel storage. These tanks are designed for land based operations. It can also be used on the decks of vessels. Smaller collapsible sizes are square shaped; larger tanks are rectangular.
