One of the largest users of gas detection safety equipment are Chemical Storage and Chemical Manufacturing Plants. Toxic, asphyxiant, and flammable gases are commonly used in manufacturing and are also by products of the manufacturing process. Storage of these gases is done on site in large metal cylinders. The transferring of gas into other containers or to other parts of the plant can release these gases into the air. Portable and Fixed gas detections systems work together to provide a safety net of gas detection...
China is a large country in the coal chemical industry. The large-scale development of the coal chemical industry has brought about huge environmental problems. The main components of coal chemical wastewater are coking wastewater, coal gasification wastewater and coal liquefaction wastewater. The components are very complex. COD, ammonia nitrogen, and phenol high content, and also contains fluoride, thiocyanide and other toxic substances, coal chemical wastewater treatment technology has become an important...
Chemical product manufacturing involves the handling of acids, carcinogenic and toxic chemicals, along with the emission of fumes that contain volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and particulates.
Electronic scrap (also named e-scrap) mainly includes discarded household appliance like refrigerator, TV, computer, washing machine, printer, fax machine, cellphone, circuit board, hard discs, CD ect. With the development of electronic industry and information technology, and electronic products’ fast replacement, the problem of e-scrap has become one of the stringent problems which need to be resolved effectively and correctly. Every year the 20 – 50 million metric tons of electronics end up in...
Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”
The first response encounters hazardous gases that need to be identified quickly. Gasmet manufactures portable and powerful gas analyzers for these crucial measurements. Measure a vast variety of gases simultaneously, on-site. Read about our solutions for First Response!
Groundwater hydrology is an interpretive science: we can’t observe the aquifers directly so we must interpolate and extrapolate our understanding from water-level measurements taken from observation wells. Stevens has expertise for measuring both water quantity and water quality.
Chemical processes make very high demands on electronic pressure measuring instruments and hydrostatic fill level probes in two respects: processes may be complex with high dynamic pressures and fast changing temperatures the media are diverse and may be chemically aggressive, explosive, toxic, abrasive and sometimes also dirty and viscous. Add to this top safety requirements, especially in explosion hazardous plant and equipment and the absolute demand for top operational reliability.
Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a...
Illicit substances real-time detection with IONICON PTR-MS. PTR-MS combines all features that are needed for analyzing dangerous and illicit substances like explosives, chemical warfare agents (CWA), toxic industrial chemicals (TIC) and drugs.
Drinking water can be produced from any natural sources like groundwater, lakes and rivers (surface waters) or seawater. Drinking water standards are set by the World Health organisation or by the European Union. Drinking water must be free of suspended solids, microorganisms and toxic chemicals. Mineral concentration recommendation vary from country to country but most of the minerals have a maximum concentration recommended to ensure safe, equilibrated and pleasant water to drink.
The Challenge: Manufacturers of personal protection devices are driven to safeguard the public health caused by airborne chemical contaminants. Removal of these contaminants is technically demanding, and manufacturers must meet this technical challenge while navigating stringent regulations. Jacobi’s understands this unique blend of technical and regulatory challenges for personal protection devices faced by our customers. Jacobi provides many different formats of product that are used in different aspect...
The nation has stockpiled thousands of cylinders and canisters of toxic and deadly chemical weapon agents, including mustard gas (HD), sarin (GB), tabun (GA), and V-agents. Most of these CWAs are stored at DOD facilities around the country and many have been in storage for years and years. As a consequence, DOD requirements specify that the stockpiles have to be monitored regularly for leakages to prevent release to the environment and exposure to personnel.
Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.
Ozone is a very effective alternative to chlorine and other chemicals as a disinfection agent in swimming pools. Ozone can safely prevent the formation of chlorine byproducts, such as chloramines and trihalomethanes which are potentially carcinogenic.
GasFinder2 can be permanently installed to monitor chemical and petroleum plants for both combustible and toxic gases. GasFinder2 can be used to replace arrays of point sensors for perimeter monitoring. A single light path will replace many point sensors. With GasFinder2 perimeter monitoring, all gas dispersed from a facility is detected and logged.
The presence of uranium in water causes radiological pollution as all uranium radionuclides decay by both alpha and gamma emissions. Chemical aspects of uranium toxicity include mainly nephritis and other renal diseases. Mentioned harmful features affect on humans even in low concentrations thus requiring sensitive analysis methods.
Due to toxic, adhesive, sticky or fatty characteristics water management at chemical plants is very challenging. Using LAR`s application-specific technology you can improve your water management efficiency by reliable on-line measurements.
The surface treatment and metal finishing industry covers a large variety of activities whose purpose is to treat metal surfaces, protect them from corrosion, enhance their appearances with metallic coatings, or improve their resistance to erosion or wear. Processes include electroplating (nickel-chrome plating, zinc plating, brass plating, hard chrome plating, silver plating, etc.), chromating or passivation, anodising, phosphating, metal pickling, etching, chemical surface treatment, hot-dip galvanizing,...
