Wastewater and process water treatment in the metal industry. Industrial waste water or circuit water in the metal industry can be broken down into many comprehensive, subject-specific areas. AWAS has developed various methods of treatment technology for the metal industry in the last 30 years. Generally we accept any environmental challenge and like to respond to individual problems.
Lead Pb, copper Cu, zinc Zn, tin Sn, manganese Mn, nickel Ni refinement Refinement of various non-ferrous metals
Precious metal refinement (Ag, Au, Pt, Pd)
Liquid electroplating waste
"Washer water" from blast furnaces
Metal finishing wastewater is a common application for ENCON Wastewater Evaporators. There are many types of wastewater generated in metal finishing. These include vibratory / tumbling wastewater, stamping wastewater, die casting wastewater and polishing wastewater. Metal Finishing wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This...
Waste water in this sector has a high concentration of heavy metals, oils and products in decomposition. The oils and emulgents lead to foam production at the water treatment plants. The treatment of these oils is very important.
Manufacturing, metal fabrication and metal finishing require multiple washing processes to remove residue, oil, acids and other lubricants and contaminants before during and following various process steps. This generates large volumes of wastewater containing alkaline, acid solutions, heavy metal wastewaters, paint, plating residue wastewater, and other metal fabrication wastewaters. Wastewater and wash water from spills and floor cleaning must also be properly disposed. These manufacturing waste waters cannot...
VACUDEST vacuum distillation systems. Premium technologies for stainless steel pickling. through stainless steel surface pickling processes, protecting the stainless steel from corrosion. This generates rinse water whose toxic contents make it impossible to discharge. It must either be treated or disposed of at high cost.
When used as part of a wastewater treatment program, Remotox (calcium polysulfide) can effectively reduce and precipitate a wide range of heavy metals. This product has proven effective even when treating chelated and/or complexed metals. Its unique formulation also removes chromates and dichromates without preliminary reduction of the chromium to the trivalent state.
Detection of heavy metal concentration in water, sea water, environmental waters and pre-treated waste water to low PPB levels using a hand held fluorimeter. Test results acquired within one minute. Technology uses DNAzyme based fluorimetric detection.
Water is essential component in the mining and steel industries. The main needs under this aspect are optimizing the management of the resources, improving productivity by treating available water for specific production process requirements and managing environmental risks by treating contaminated pond and underground mine water to remove suspended solids and in particular heavy metals (SS), arsenic and other contaminants for safe discharge into sensitive environment.
Reliably distilling complex and heavy metals: VACUDEST in electroplating applications. No company applying electroplating likes having to deal with the issue of “wastewater”. But what happens when authorities take samples of the wastewater unannounced, and finds the nickel limit has been well exceeded? A horror scenario resulting in a lot of stress, work and expense.
Using innovative recycling technologies in vibratory grinding processes. Rinse water from vibratory grinding processes ca be contaminated with heavy metals, oils and, depending on the process, even a variety of chemicals. It cannot be discharged into the public sewer system, and usually requires to be disposed of with specialized waste management companies expensivly. But there are alternatives: Vacuum distillation with VACUDEST evaporators is an economical, resource-friendly method for treating this industrial...
Proper rinsing is one of the most important steps in quality manufacturing or metal finishing. Plenty of low cost, good quality water for rinsing has been available in the past, so rinse water conservation has been largely ignored. Today, this is no longer true. Tap water costs have increased dramatically. Various new regulations are now in effect which limit the allowable volume of wastewater. Others require wastewater treatment. Still other laws tax the amount of water going down the sewer. These factors have...
Assembly of many electronic components involves multiple washing processes to remove residue, oil, acids and other lubricants and contaminants before during and following various process steps. This generates large volumes of wastewater containing alkaline, acid solutions, heavy metal wastewaters, paint, plating residue wastewater, and other metal fabrication wastewaters. Polishing, grinding and dicing operations in semiconductor manufacturing produce wastewater high in suspended solids, including silica,...
Printing and Photo Processing Wastewater Treatment and Disposal. The printing industry and photographic processing produce a tremendous amount of waste water, from washing prints, cleaning between color changes, cleaning ink shipping containers and cleaning ink delivery systems. The wastewater produced is often contaminated with heavy metals and other highly toxic materials.
