Customer Pain Points-DIEN Water Treatment

Black and odorous rivers/lakes, pollution of water sources, affecting ecology and water supply safety; Water treatment equipment has frequent operational failures, large fluctuations in water quality, and a lack of professional maintenance.

Excessive Organic Pollutants

High concentrations of COD, BOD₅, and TOC can lead to poor biodegradability of water bodies and easily cause eutrophication;
Excessive Nitrogen and Phosphorus

High levels of ammonia nitrogen, total nitrogen, and total phosphorus are the core causes of black and odorous water and blue-green algae outbreaks;
Suspended Solids/Turbidity Exceeding the Standard

Wastewater contains a large amount of solid residue, sediment, and colloids, making the water turbid and increasing the subsequent treatment load;
Excessive Pathogenic Bacteria/Microorganisms

Hospitals, medical facilities, and domestic wastewater contain bacteria, viruses, and pathogens, which can easily cause the spread of epidemics;
Abnormal Acidity or Alkalinity

The pH value in acid pickling, chemical, and mining wastewater is too high or too low (strong acid/strong alkali), which corrodes equipment and damages water ecology.
Trace Pollutant Residue

After regular treatment, the reclaimed water still contains trace amounts of COD, ammonia nitrogen, phosphorus, and suspended solids, which do not meet the industrial production water replenishment standards;
Excessive Salt Ions

The high content of inorganic salt ions such as sodium, chlorine, and sulfate ions in high salt wastewater from coal chemical, power, printing and dyeing industries can easily cause equipment scaling and process failure when reused;
Hardness/Alkalinity Rebound

During the storage or transportation of reclaimed water, calcium and magnesium ions, as well as alkalinity, increase again, affecting the safety of reuse;
Trace Heavy Metal/Organic Residue

After basic treatment, electroplating and chemical wastewater still contains trace amounts of heavy metals and recalcitrant organic compounds, which can affect product quality when reused;
Total Dissolved Solids (TDS)/High Conductivity

The total amount of soluble salts in the water body is too high, and the conductivity exceeds the standard, making it unable to meet the high-precision production water demand.
