Industrial Wastewater (Tradewaste) Treatment
On-site tradewaste treatment may be required to achieve compliance and/or reduce disposal costs, whether discharging on-site or to trade wastes systems.
Where tradewaste discharge consent compliance is not being achieved; IWS can assist with a range of solutions to the problem. These include:
- pH correction
- Oil and grease and solvent removal
- Metals removal
- Solids and colour removal
- Segregation of waste streams
- Existing wastewater treatment plant improvement
- Containment of process wastewater
These systems will range from small, “low tech” manual systems, through to complex automated systems, depending on the characteristics and scale of the industry and its wastewater.
IWS has considerable experience with anything from a conceptual design to a “turn key” solution.
