Industrial processes, such as metalworking and surface treatment, often release complex wastewater streams contaminated with heavy metals and other harmful substances. These substances – including zinc, copper, nickel, chromium and sometimes even cyanide – can cause serious environmental damage if not disposed of properly. <\/p>\n
Physico-chemical treatment techniques offer an effective solution for treating such wastewater streams. Dissolved metals are converted via chemical reactions into insoluble compounds, which are then physically separated from the water. <\/p>\n
For Mauquoy Token Company, a producer of high-quality metal coins and tokens in Olen, Belgium, TASK<\/span> realised a customised physico-chemical water treatment plant. The challenge in this project was not only the removal of various heavy metals, but also the degradation of cyanide, a highly toxic substance that sometimes occurs in very small quantities in metal surface treatment. <\/p>\n The installation involves several process steps:<\/p>\n Thanks to this installation, Mauquoy now meets the stringent discharge standards. The treated wastewater can be safely discharged, while the contaminated sludge is disposed of by authorised processors. <\/p>\n The approach at Mauquoy demonstrates how flexible and targeted physicochemical techniques can be used to treat complex industrial wastewater streams, even in the presence of difficult-to-remove components such as cyanide.<\/p>\n [\/et_pb_text][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6Ijc4OSIsImVuYWJsZV9odG1sIjoib2ZmIn19@” button_text=”Physico-chemical water treatment” button_alignment=”center” _builder_version=”4.27.4″ _dynamic_attributes=”button_url” _module_preset=”default” button_bg_color=”#3F64CC” global_module=”1927″ saved_tabs=”all” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/task.be\/wp-content\/uploads\/2025\/03\/fysisch-chemische-waterzuivering-voor-zware-metalen.jpg” alt=”physico-chemical wastewater treatment for removal of heavy metals and cyanide from wastewater” title_text=”physico-chemical water treatment for heavy metals” align=”center” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_image src=”https:\/\/task.be\/wp-content\/uploads\/2025\/03\/filterpers-fysisch-chemische-waterzuivering.jpg” alt=”filter press physico-chemical water treatment for removal of heavy metals and cyanide from wastewater” title_text=”filter press physico-chemical water treatment” align=”center” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Heavy metals or other chemical components such as cyanide should be removed from wastewater before discharge to sewer or surface water.
