A common application for small scrubber systems is an emergency vent scrubber for laboratories. Envitech's lab scrubber is a packaged packed bed absorber designed for high efficiency removal of water soluble contaminants (e.g. HCl, HF, HBr, SO2, NO2, etc.) from the gas [...]

A Venturi scrubber is a common air pollution control device that is used to remove particulate. Because it is a wet scrubber, collected particulate is purged in a liquid discharge stream called the blowdown. Venturi scrubbers are commonly used for [...]

Envitech is proud to launch a new scrubber service and maintenance program for all users of air pollution control equipment.  Envitech offers the program to provide plant managers, environmental departments, plant engineering and operations and maintenance staffs access to our [...]

For years, many states have exempted industrial facilities from rules prohibiting the release of toxic pollution during startup, shutdown, and malfunctions. That could all soon change.  On May 22, 2015, the U.S. Environmental Protection Agency (EPA) finalized a rule which [...]

With an expanding global population, demand for minerals continues to grow.   Development of non-traditional resources is expected to increase to meet this growing demand. This includes copper resources challenged by high levels of arsenic.  Mining operations may incur penalties for [...]

A geothermal plant produces a sustainable source of energy by converting super heated fluids from the earth’s geothermal resources into electrical energy.  The fluids are recovered in theprocess and re-injected back into the earth. The following YouTube video from CalEnergy provides a [...]

The purpose of a wet electrostatic precipitator (WESP) is to remove particulates that are smaller than one micron from a gas stream.  One of the common industrial applications is downstream of standard pollution control equipment on power plants or pulp [...]

A common application for Venturi scrubbers is potash mining.  Venturi scrubbers are used to remove particulate from industrial dryers that dry the potash material.  A cyclonic separator or chevron style entrainment separatordownstream of the Venturi removes particulate–laden water droplets from [...]

NOx refers to a class of pollutants that is any binary compound of nitrogen and oxygen and is a main contributor to what is commonly referred to as smog.  It is most commonly produced in combustion processes, but can also [...]

Venturi scrubbers are commonly used in pollution control systems as particulate control devices. Particles are collected primarily according to their aerodynamic size through inertial mechanisms.  Good particle collection is achieved by maintaining a high differential velocity between particles in the [...]
