A reuse plant replaces municipal potable water with treated wastewater for industrial use
The severe drought that first gripped Western Cape province in 2014 drove local municipalities to enforce stringent water restrictions and increase water tariffs on all water users. ArcelorMittal took a proactive approach to the crisis and replaced a significant portion of their potable intake with treated and polished wastewater for use in their industrial processes. In addition to alleviating stress on the municipal grid, the client was able to achieve cost savings and future water security.
PROXA integrated a new plant upgrade and expanded the existing plant to replace the potable feed intake with treated wastewater. PROXA’s fast-track programme ensured water security and cost savings for the client.
HOW PROXA ADDED VALUE
PROXA’s ability to deliver a cost effective solution, coupled with our access to global procurement, made further expediting possible to meet the tight delivery deadline. Innovation in terms of a compact design and construction enabled rapid installation, reduced site work requirements, and a shortened project programme. A thorough knowledge of the downstream membrane treatment process enabled the team to integrate the solution and maximise the reuse of existing equipment.
- 3.2 MLD per day
- Air assisted disc filtration
- Micro filtration
- Reverse Osmosis (RO)
- Brine treatment
- Chemical dosing
The plant was designed and built by a highly experienced team who optimised the existing processes on site to ensure reliability of the new plant configuration. The site operations team is supported by PROXA’s local technical centre.
ENVIRONMENTAL PROTECTION AND COMMUNITY INVOLVEMENT
The implementation of this plant has made additional potable water available on the local municipal grid for domestic use. All generated wastes are managed and treated within the existing plant to ensure that no additional brine is discharged from the site.
