A North American railway that prides itself on environmental responsibility recently worked with an engineering firm
to design a new wastewater treatment facility for one of its refueling stations in British Columbia. The
design challenge required a careful balance of meeting the railway’s commitment to environmental
sustainability, while still being able to operate in severe weather conditions – even temperatures as
low as -40 degrees Fahrenheit.
Chemical plants that manufacture or otherwise process chemicals (on a
large-scale) face unique challenges when it comes to wastewater management. While the equipment, technology
and processes used at chemical plants varies, the Environmental Protection Agency’s (EPA) Clean Water Act requires plants
to meet certain performance standards aimed at water pollution prevention and treatment.
Under the Act, the EPA has implemented pollution control programs such as establishing wastewater standards
that require wastewater to be virtually free of oil and other contaminants. Chemical plants that don’t...
This Oil Skimmers, Inc. customer has been a producer of highly
refined mineral oils for more than a century. The company’s white oil products, which are used in the
formulation of lotions, creams, ointments and hand cleansers, require large amounts of water to make. The
oily water from the refining process, along with tank washdowns and runoff, adds up to a substantial
wastewater challenge. In an effort to improve its wastewater treatment process and increase overall plant
In industrial machining
and grinding operations, metalworking fluids are used to reduce heat and friction and remove metal
particles. Fluids can be water-based, including soluble oils and semisynthetic fluids, oil-based, such as
petroleum oils, or a mixture containing anything from oils, emulsifiers and anti-weld agents to corrosion
inhibitors and biocides, among others.
Oil skimmer reduces cost, increases performance and decreases material waste
are tasked with managing oil in the wastewater from their manufacturing processes on an ongoing basis.
Recently, a privately-held snack food manufacturer that produces potato chips established a goal to increase
chip production by 20 percent. However, increasing production also meant increasing the amount of cooking
oil discharged into the wastewater from washing the fryers used to cook the chips....
