Study on the treatment of copper-electroplating wastewater
Yijiu et al. [16] studied the treatment of copper-electroplating wastewater by chemical trapping and flocculation recently. The electrolytic process does not generate sludge (requiring disposal by
The electrocoagulation process was successfully applied to the treatment of an electroplating wastewater sample. Its Cr (VI) ion concentration and COD were effectively reduced under the admissible
Treatment of Electroplating Wastewater Containing Cu2
Treatment of Electroplating Wastewater Containing Cu2+, Zn2+ and Cr(VI) by Electrocoagulation Article in Journal of Hazardous Materials 112(3):207-13 · September 2004 with 2,937 Reads
Electroplating industries discharge large amounts of heavy metals, including chromium (Cr), iron (Fe) and zinc (Zn) ions in wastewater resulted from technological processes, including in sludge
Utilization of nickel-electroplating wastewaters
Some approaches have been taken by using the slurries produced after the chemical treatment of nickel electroplating wastewater, in the manufacture of construction and building materials such as ceramic breaks, tiles, cement, concrete, etc. (Yin et al., 2008); however, all these products face the risk of leaching of heavy metal ions during

From sulfuric acid electroplating wastewater (g/dm³: 4,16 Re; 0,34 W), containing impurities of sodium fluoride, potassium perrhenate was precipitated by potassium chloride or hydroxide. It was established that the best precipitant for this solution is potassium hydroxide.
Efficiency of oxidation ponds in wastewater treatment (78.93 KB) A research was conducted at Kauma oxidation ponds, a Sewage water treatment plant found in Lilongwe, Malawi with an aim of establishing the efficiency of these sewage treatment ponds in treating sewage wastewater.
gold cyaniding neutralization
Gold electroplating is a very safe process when done by professionals. One concern with gold plating, however, is that it masks the other metals. If you have a metal allergy, you may be exposed to the allergen as the gold plating tarnishes and the coating wears away. Read More → leach tank acid equipment m traiteur.ch

- What are water treatment chemicals?
- 2. Water treatment chemicals – the full picture Water treatment chemicals are the solid core of water treatment processes. They became essential about a hundred years ago, after an expert panel discussion on the chlorination of potable water as a means of preventing waterborne diseases [ 9 ].
- What are the different types of water treatment?
- A separate type of water treatment is desalination water treatment, where minerals from sea water can be removed to make the sea water usable for industrial, agricultural, or domestic applications (Lattemann and Höpner 2008).
- What technologies are used in water treatment?
- So, new and innovative technologies have been introduced, such as membrane filtration, sonication, photocatalysis, redox mediators, and enzymatic therapies. These developing technologies could offer better solutions to current IWW and public health treatments. Various water treatment technologies are summarized in Figure 3.
- What is the global market for membrane water treatment chemicals?
- Indeed, the global market for membrane water treatment chemicals was worth around USD 14.70 billion in 2015 and is expected to exceed USD 20.71 billion by 2025, with a CAGR of 7% forecast during the period 2017–2025 [ 16 ].
