Many people hold a misunderstanding that household water purifiers can ensure safe drinking water, which does not match objective facts. Water purifiers perform well for daily tap water with preliminary treatment, but they cannot properly treat heavily polluted raw water. Relevant test data supports this conclusion. Two groups of water samples were compared: one filtered by household purifiers and the other taken from natural water bodies, with clear differences observed between them. The natural water sample gradually turned turbid during observation, while purified water remained stable. Nevertheless, some water purifier manufacturers use overstated promotional content, leading the public to mistakenly believe household purifiers can filter various pollutants in raw water, an opinion without scientific support.
To acquire accurate water quality data, Online Water Quality Monitoring devices are essential for continuous real-time tracking of multiple indicators. They can detect whether pollutant concentrations exceed standard limits and verify if treated water complies with standards for discharge or recycling.
Water quality monitoring allows comprehensive tracking of regional water environment conditions. Hangzhou Modi Water Quality Analyzers refer to a full series of multi-parameter monitoring devices, covering detectors for COD, ammonia nitrogen, total nitrogen, total phosphorus, heavy metals, biological toxicity, coliform, total residual chlorine, chroma and hardness. Its core products consist of Online Coliform Analyzers, Online Water Biological Toxicity Analyzers, Online Total Residual Chlorine Analyzers and Rare Heavy Metal Online Monitoring Equipment, etc. These instruments feature full-automatic operation and reasonable reagent consumption.
They are widely applied in automatic water environment monitoring systems, sewage treatment plants, cross-regional water monitoring points, water quality laboratories, wastewater discharge outlets and environmental management authorities at all levels. Major applicable scenarios include water pollution monitoring for industries such as wastewater treatment, paper-making, steel manufacturing, pharmaceutical production, electroplating and printing.
