Wastewater systems are vital to the continued environmentally safe and sound performance and growth of communities throughout the world. Wastewater engineers promote stewardship in the operation, maintenance and management of various types of sanitary or foul water collection systems.
Public health authorities in some countries regulate the quality of water in public pools and control water treatment tightly. A typical installation comprises several instruments with a common web-server for access via intranet or internet.
Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l: 0.5 – Japan, Russia; 1 – Argentina, Australia, Brazil, China, EC; 2...
Waste water is any water that has been adversely affected in quality by anthropogenic influence. Municipal wastewater is usually conveyed in a combined sewer or sanitary sewer, and treated at a wastewater treatment plant or septic. Treated wastewater is discharged into receiving water via an effluent sewer.
It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oil and Grease (FOG). With significant growth in the commercial food sector on top of other high FOG producing industries such as metal processors, meat packers, cosmetic manufacturers and industrial laundry establishments, the need for publicly owned treatment plants (POTWs) and industries to regulate and monitor FOG is crucial to public health. Besides clogged sewer lines, high FOG levels also disrupt the effective operation of a...

Oil and gas companies, whether in coastal or offshore settings, use water in various stages of production and for drinking and sanitary purposes. Process water, feed water and wastewater requires disinfection and filtration treatment prior to use, reclamination or discharge. De Nora Water Technologies has been providing water and wastewater treatment solutions to the oil and gas markets for more than 25 years.
The content of water-soluble forms of inorganic cations (ammonium, potassium, calcium, sodium, magnesium) is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.
In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.
In remote locations and mine sites distant from the nearest outpost, WesTech provides package plants for water treatment and for wastewater process that allow for drinking water to be made onsite and basic levels of sanitary safety to be met, allowing for continued production and a healthier site and workforce.
Fresh vegetables and fruits products require ice and/or chilled ice for preservation of quality. Ice and /or chilled water are used at all points in the chain of produce processing – ice is added during harvest process to start removal of the field heat from the product, top icing during processing, and liquid ice injection of boxes prior to shipment to the market, or central processing areas, or the end user. Processing requires continuous temperature control to maintain the best quality and extend the...
