Ultra-filtration Water Plant
Why Was the Water Plant Upgrade Needed?
What Were the Original Issues?
The plant was old and used chemical-intensive and labor-intensive systems. Efficiency of water treatment was low, expenditures were high, and fines for environmental infractions contributed to financial burden.
What Was the Financial Drain?
In total, the plant lost more than R1 million per month on:
- Chemical purchases
- Sludge removal logistics
- Emergency maintenance
- Excessive labor costs
- Regulatory penalties
It was apparent that the same operational model could not be sustained. A revolution was called for — one that enhanced efficiency, safety, and cost-competitiveness.
Action 1: Electrocoagulation (EC)
Electrocoagulation is a chemical-free process that uses electrical current to destabilize and eliminate suspended solids, heavy metals, and emulsified oils.
How WCSP Used It?
WCSP utilized modular EC units customized based on influent water characteristics. These modules were installed in parallel with minimal footprint and downtime.
Monthly Savings: R180,000
- Replaced more than 70% of chemical coagulants
- Lowered sludge production considerably
- Reduced storage and handling expenses
- Eliminated risks associated with chemical exposure
Action 2: Sludge-Free Bioremediation
Bioremediation employs useful microbes to degrade organic waste, eliminating the use of synthetic chemicals.
WCSP’s Strategy:
WCSP employed specific, non-pathogenic bacteria strains to metabolize wastewater’s BOD/COD—providing a sludge-free, environmentally friendly process.
Monthly Savings: R140,000
- 90% reduction in hauling and sludge disposal
- Fewer clean-outs resulted in less downtime
- Improved effluent quality for reuse
Action 3: Advanced Oxidation Process (AOP)
AOP applies highly reactive hydroxyl radicals to oxidize recalcitrant organic pollutants like pharmaceuticals, dyes, and pesticides.
WCSP’s Installation
WCSP ensured almost complete disinfection and chemical breakdown by incorporating UV + H₂O₂-based AOP units in post-treatment processes.
Monthly Savings: R70,000
- Prevented discharge penalties
- Eliminated need for retreatment
- Enhanced the plant’s compliance rating
Action 4: Moving Bed Biofilm Reactor (MBBR)
MBBR is a mobile carrier-based biological treatment process that offers surface area for bacteria to colonize and break down waste efficiently.
WCSP implemented a high-density media system to manage higher inflow loads without increasing infrastructure.
Monthly Savings: R45,000
- Increased BOD/COD removal capacity
- Avoided expensive system overflows
- Improved shock load resilience
Action 5: SCADA Automation
SCADA (Supervisory Control and Data Acquisition) offers centralized, real-time monitoring and control for industrial processes.
WCSP’s SCADA Integration
WCSP installed sensors, control panels, and dashboards for remote operation and alerts — filtration, flow rate, chemical dosing, and tank levels.
Monthly Savings: R110,000
- 40% less manual labor
- Faster malfunction detection
- Prevented expensive emergency repairs
- Improved energy efficiency with intelligent scheduling
Action 6: Closed-Loop Water Recycling
Treated water is recycled for internal use such as equipment washing, cooling towers, or gardening within a closed-loop system.
WCSP’s System Design
Treated water from the last outlet was diverted to an auxiliary tank and piped to reuse applications — reducing draw from municipal sources.
Monthly Savings: R85,000
- Water procurement costs reduced
- Reduced external discharge volumes
- Enhanced sustainability KPIs
Action 7: Energy Optimization Plan
Energy was optimized by:
- High-efficiency pumps
- Variable Frequency Drives (VFDs)
- Scheduled operation during off-peaks
WCSP’s Implementation
Energy audits pinpointed wastage areas. Systems were retrofitted to align performance demand with minimal use of electricity.
Monthly Savings: R130,000
- Decreased monthly power bills
- Increased equipment life
- Reduced carbon footprint
