Chemical water treatment equipment mitigates the formation of scale, calcium carbonate deposits, in process water systems such as cooling towers, boilers and heat exchangers by controlled chemical addition and system monitoring.
Coagulation equipment promotes the destabilization and initial aggregation (flocculation) of finely divided, suspended solids by the application of a magnetic field, the addition of a coagulant, or a biological process.
Composting equipment is used to create compost, a dark, rich soil conditioner (humus) which is created through the biological reduction or organic material.
Condensate polishers use ionic exchange to remove mineral contaminants that can limit performance and reduce system life in boilers, heat exchangers, HVAC cooling towers, steam turbines, nuclear power plants, and industrial processes.
Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.
Deionizers remove the ionized minerals and salts (both organic and inorganic) from a solution by a two-phase ion exchange procedure.
Desalination equipment is used to remove salts and other minerals from water or soils, typically for drinking water, oilfield, and process separation applications.
Distillation equipment and solvent recovery systems are used for steam and wastewater stripping, chemical product purification, and solvent recovery.
Downdraft tables are self-contained, portable filtration systems that remove harmful particulates and return filtered air.
Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams or to remove granular solid pollutants from exhaust gases prior to venting to the atmosphere.
Electric and magnetic water filters use electrical charging and magnetic energy to treat water and wastewater.
Emission concentrators route contaminants from large volume, low concentration exhaust streams into low volume, higher concentration streams, typically by use of a rotor concentrator.
Fixed growth treatment systems attach microorganisms to a surface that is exposed to water.
Gas flares, alternatively known as a flare stacks, are used to eliminate waste gas, which is released via pressure relief valve when needed to ease the strain on equipment.
Groundwater monitoring equipment includes pumps and other instruments that tap into the water table for water quality assessment, testing for pollutants, and the identification of other compounds.
High-efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters are designed to screen particles larger than 0.3 µm
Incinerators are used for burning organic material, gases, fumes, hazardous waste, and municipal trash or sewage sludge at a high temperature, sometimes to produce energy.
Ion exchange equipment adjusts the ionic content of water.
Membrane bioreactor systems combine ultra-filtration technology with biological treatment for municipal, commercial and industrial wastewater treatment and water reuse applications.
Mist collectors reduce the amount of mist in the workplace atmosphere.
Neutralization equipment promotes the chemical process that produces a solution that is neither acidic nor alkaline.
Nitrification systems are used to control ammonia levels. Denitrification systems are used to turn nitrate into gaseous nitrogen species.
Oil in water monitors are used to detect the presence of hydrocarbons in water.
Oxidation equipment sterilizes wastewater via oxidative chemical processes.
Pond and lagoon aerators are devices that bring air into contact with water, often by spraying water through air or bubbling air through water.
Precipitation systems promote the phenomenon that occurs when a substance held in solution passes out of solution into a solid form.
Refining and recovery equipment include systems for the purification and treatment of metals, precious alloys, oils, fuels, and other valuable constituents from waste streams or raw materials.
Rotating biological contactors are large discs on rotating shafts that are mounted in wastewater tanks, but only partly submerged. As the discs turn, the microorganisms on them repeatedly contact both air and the organic substances in the water.
Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.
Selective catalytic reduction (SCR) systems inject ammonia into boiler flue gas and pass it through a catalyst bed where the nitrogen oxide gas (NOx) and ammonia react to form nitrogen and water vapor.
Sequencing batch reactors (SBR) are fill-and-draw activated sludge systems for wastewater treatment. Wastewater is added to a single "batch" reactor, treated to remove undesirable components, and then discharged.
Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum.
Spill containment systems are used to capture and contain unintentional spills of liquid media. They are also called secondary containment systems.
Submersible mixers can be immersed totally in wastewater to maintain a mixture of fluids and solids.
Suspended growth treatment systems freely suspend microorganisms in water.
Thermal oxidizers and catalytic oxidizers are used to destroy volatile organic compounds (VOC) in process gases.
Ultrapure water equipment is used to provide high-purity deionized water (DI water) to the semiconductor and pharmaceutical industries.
UV light systems provide ultraviolet light for identification, tracing, curing, disinfection or processing applications.
Vacuum cleaners are capable of picking up large quantities of material and/or liquids. They can be portable devices or part of a central vacuum system.
Wastewater pumps are used in the collection of sewage, effluent, drainage and seepage water.
Wastewater treatment equipment is used to treat, remediate, and process effluent wastewater.
Water disinfection systems treat water to inactivate, destroy, and/or remove pathogenic bacteria, viruses, protozoa, and other parasites. Common methods include chlorination and alternative disinfectants.
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.
