A managed and optimized pickling or milling process with Scanacon reduces the overall amount of waste resulting from the pickling or chemical milling line. Reducing the primary by-products of pickling and milling – metal oxide sludge’s, waste liquor, acid gasses and acidic waste water from rinses – reduces the quantity of hydroxide sludge that results from it’s treatment by 40% or greater. Pickling and milling results in the production of environmental pollutants in the form of solids, liquids and gasses, all of which require appropriate treatment prior to disposal or discharge. In some instances stainless and speciality alloy producers are coming under increased regulatory pressure to limit releases of nitrogen bearing wastes such as NO /NO2 gas and nitrate (NO3-) ions into the environment. Reducing overall water usage and it’s discharge is quickly becoming a focus of stainless steel and speciality alloy producers, worldwide. A closed loop pickling or milling line while technologically possible remains at present a challenge given the complexity and economics to achieve it. Nevertheless, reductions of 90% or greater in fresh water usage and up to 60% of the nitrate (NO3-) associated with the pickling line is economically achievable with existing technology today.



An increasing environmental awareness of society and governmental legislation today is a constant reminder of the impact of industry on the environment. Discharge of contaminants to water and air as well as resource usage are issues found in the industry all over the globe.


With our products, systems and services, Scanacon minimizes pollutants and waste volumes resulting from the finishing processes used in the production and fabrication of Stainless Steels, Titanium, Zirconium and other specialty alloys.


Our proven technology has demonstrated significant environmental benefits around the world. Each kilogram of nitric acid saved means nearly one kilogram of nitrate eliminated from the environment and considerable precious water resources preserved.


One kilogram of nitrate released into environment requires more than 100,000 liters of water to dilute it to a level considered safe for human consumption. Scanacon offers a better solution than “dilution” – a single Scanacon ModuFlex system in a year can save more water than what is used by the entire city of New York in a week.


With over 30 years experience, Scanacon has the knowledge, equipment and expertise to help deliver solutions to environmental issues combining financial, environmental and production improvements for the customer.
