Solving Common High Turbidity with Chlorine in Emergency Water Treatment: A Case Study
Introduction
High turbidity in water sources presents a critical challenge for water treatment facilities, particularly during emergency situations such as natural disasters or infrastructure failures. Turbidity not only affects aesthetic quality but also complicates disinfection processes, increases treatment costs, and poses significant health risks. This case study details how ENVO CHEMICAL successfully resolved a high-turbidity emergency at a municipal water treatment plant in Southeast Asia, demonstrating the effectiveness of chlorine-based solutions in critical water treatment scenarios.
The Challenge: Emergency Turbidity Crisis
In March 2023, a severe monsoon season triggered flash flooding across a major river basin serving a population of 500,000 residents in Southeast Asia. The floodwaters carried unprecedented levels of suspended solids, causing the raw water turbidity to spike from a normal 15 NTU to over 350 NTU within 48 hours. The existing water treatment facility, designed for 50 NTU, faced imminent operational failure. The high turbidity levels compromised the effectiveness of conventional coagulation and filtration processes, resulting in:
- Inconsistent disinfection efficacy (reduced chlorine residual)
- Frequent filter clogging
- Non-compliance with WHO drinking water standards (turbidity limit: 1 NTU)
- Risk of waterborne disease outbreaks
The local water authority urgently sought a solution to prevent a public health emergency while maintaining operational continuity.
ENVO CHEMICAL’s Solution: Chlorine-Based Turbidity Management
ENVO CHEMICAL’s technical team was contacted within 2 hours of the emergency, leveraging our global service network and rapid response capabilities. After analyzing the water chemistry, our specialists recommended a two-phase approach:
- Immediate Turbidity Reduction: Implementation of ENVO’s proprietary chlorine-based coagulant enhancer (ENVO-CL-500), which combines chlorine with optimized coagulant chemistry to effectively bind suspended particles.
- Sustained Disinfection: Deployment of ENVO’s stabilized sodium hypochlorite (ENVO-CHLOR-25) for consistent disinfection despite high turbidity.
Unlike conventional approaches that require complete system shutdown for coagulant adjustment, ENVO’s solution was implemented within the existing treatment process with minimal operational disruption.
Implementation Process
Our technical team executed a precise, phased implementation over 72 hours:
- Phase 1: Emergency Response (0-24 hours)
- ENVO’s logistics team delivered 5 tons of ENVO-CL-500 within 12 hours of order placement (leveraging our Asia-Pacific distribution hub)
- On-site technical specialists trained plant operators on the new dosing protocol
- Initial chlorine-enhanced coagulation setup integrated with existing treatment infrastructure
- Phase 2: Optimization (24-48 hours)
- Continuous turbidity monitoring (using portable Hach turbidimeters)
- Adjusted dosing rates based on real-time water quality data (0.5-1.2 mg/L ENVO-CL-500)
- Enhanced chlorine residual monitoring to ensure disinfection efficacy
- Phase 3: Stabilization (48-72 hours)
- Implementation of ENVO-CHLOR-25 for consistent disinfection
- Documentation of optimized dosing protocols for long-term use
Quantifiable Results and Cost-Benefit Analysis
Within 72 hours, the treatment facility achieved remarkable improvements:
| Parameter | Pre-Implementation | Post-Implementation | Improvement |
|---|---|---|---|
| Turbidity (NTU) | 350+ | <2.0 | 99.4% reduction |
| Disinfection Efficiency | 65% | 98% | 43% increase |
| Filter Run Time | 1.5 hours | 8 hours | 433% increase |
| Chemical Consumption | 12 kg/day | 7.5 kg/day | 37.5% reduction |
| Compliance Rate | 0% | 100% | Full adherence to WHO standards |
Cost-Benefit Analysis:
- Total emergency solution cost: $14,200
- Traditional alternative (system overhaul): $185,000
- Savings: $170,800 (92.3% cost reduction)
- Operational savings: $2,500/day from reduced chemical usage and extended filter life
The solution not only resolved the immediate emergency but also provided a sustainable approach to managing seasonal turbidity spikes, with the facility reporting a 30% reduction in annual chemical costs post-implementation.
ENVO CHEMICAL’s Global Support Advantage
This success was made possible by ENVO CHEMICAL’s integrated global service model:
- 24/7 Technical Support: Our regional water treatment specialists provided real-time guidance via WhatsApp and video conferencing, eliminating time zone barriers.
- Rapid Logistics Network: Leveraging our distribution centers in Qingdao, Singapore, and Rotterdam, we delivered critical chemicals within 24 hours globally.
- Customized Product Solutions: ENVO-CL-500 was specifically formulated for this high-turbidity scenario based on water chemistry analysis.
