The technicians at Pioneer Industrial know that plant wastewater disposal can be difficult and expensive. Chemical, pulp, raw sewage, and petrochemical plants must ensure concentrations in wastewater effluents comply with the local and national regulations. Otherwise, treated water cannot be being released into rivers, lakes, or oceans. Certain plants even rely on internal water recycling before proceeding with primary treatment, cleaning, and disposal. Issues such as high concentrations of carbon dioxide in municipal wastewater can threaten biological processes and cause environmental damage. Cleaned water also must meet biochemical oxygen demand standards.
