Whether for human consumption, industrial use, agriculture, or environmental sustainability, the quality of water has a direct impact on health, safety, operational efficiency, and compliance with regulations. Water analysis is the critical process that ensures water sources meet the required standards, helping to identify and control contaminants before they cause harm.
At Prei Instrumentation, we recognise the importance of precise and reliable water testing. Our water analytics solutions are engineered for a broad range of applications across industries, ensuring complete control over water quality with advanced technology and trusted expertise.
What is Water Analysis?
Water analysis involves testing and evaluating water samples to determine their chemical, physical, and microbiological composition. This process ensures the water meets the quality criteria for its intended use, whether that’s drinking, industrial processing, or environmental discharge.
Key aspects of water analysis include:
- pH measurement
- Conductivity and salinity
- Turbidity and clarity
- Dissolved oxygen
- Chemical oxygen demand (COD)
- Biological oxygen demand (BOD)
- Presence of heavy metals, bacteria, or nitrates
- Water hardness
Regular water testing is the cornerstone of water safety and effective treatment strategies.
Why Water Analysis Matters
- Health and Safety: Unsafe water can lead to severe health risks such as cholera, hepatitis, and heavy metal poisoning. Water analysis detects harmful bacteria, pathogens, and chemical contaminants that pose risks to human and animal health.
- Environmental Protection: Runoff from industrial and agricultural activities can introduce pollutants into rivers, lakes, and oceans. Water analysis helps monitor these discharges and ensures compliance with environmental regulations.
- Operational Efficiency: In sectors like mining, food processing, and power generation, poor water quality can cause corrosion, scaling, and equipment failure. Continuous water monitoring ensures system longevity and optimal performance.
- Regulatory Compliance: Strict local and international water quality standards must be met. Regular analysis ensures your facility complies with government regulations such as SANS 241 for drinking water in South Africa, or effluent discharge laws in industrial applications.
- Cost Savings: Identifying water quality issues early prevents costly downtime, system damage, and legal penalties. Proactive water management enables smarter, more efficient operations.

Key Water Analysis Parameters Explained
To appreciate the value of water analysis, it’s important to understand the main parameters tested:
- pH Level: Measures the acidity or alkalinity. Critical for chemical reactions and biological processes.
- Turbidity: Indicates the presence of suspended particles, affecting clarity and microbial activity.
- Conductivity: Shows the ionic content of water, a measure of dissolved salts or impurities.
- Dissolved oxygen (DO): Essential for aquatic life; low DO indicates pollution or poor water quality.
- COD and BOD: Determine the organic matter content in water, helping assess pollution levels.
- Microbiological Tests: Identify harmful bacteria like E. coli or coliforms.
- Heavy Metal Testing: Detects dangerous substances like lead, arsenic, or mercury.
- Water Hardness: Ensures accurate assessment of mineral content.
The Future of Water Monitoring: Smart Analytics
At Prei Instrumentation, we integrate smart analytics and IoT to provide facilities with real-time access to critical data. With cloud-enabled water monitoring, organisations can access performance dashboards, track long-term trends, and receive alerts to prevent failures or contamination.
These technologies are transforming how water is managed, moving from reactive measures to predictive maintenance and proactive environmental stewardship.
FAQs About Water Analysis
Who needs water analysis?
Any facility that uses water for drinking, manufacturing, agriculture, or waste discharge requires water analysis to ensure safety and compliance.
How often should water be tested?
The frequency depends on your industry, the type of water source, and applicable regulatory requirements. Drinking water should be tested regularly (monthly or quarterly), while industrial systems may require continuous monitoring.
What’s the difference between chemical and microbiological testing?
Chemical testing evaluates mineral and pollutant levels, while microbiological testing checks for the presence of bacteria and pathogens.
What equipment does Prei Instrumentation supply?
We supply full-spectrum water analytics solutions, including multi-parameter sensors, monitoring stations, data loggers, and smart integration systems.
