COD (Chemical Oxygen Demand) refers to the degree of pollution caused by organic matter (contaminants) in marine and lake environments, represented by a numerical value. A higher COD indicates a greater amount of organic matter (contaminants) in the water, meaning that there are more substances that readily react with oxygen present. BOD (Biochemical Oxygen Demand) is often confused with COD. While both are indicators of water pollution, there are key differences: COD: Represents the degree of pollution in lakes and marine areas, measured using oxidizing agents. BOD: Represents the degree of pollution in rivers, measuring the amount of oxygen consumed by microorganisms over five days. *For more detailed information, please refer to the related links.

• Water quality testing

As the movement to reuse domestic wastewater (gray water) for planting and irrigation spreads, regular monitoring of pH and EC (electrical conductivity) has become a key factor influencing the reliability of wastewater treatment. This article introduces the importance of pH and EC as indicators of wastewater quality management, along with actual measurement examples. Domestic wastewater refers to the portion of water discharged from households, excluding toilet water (such as from kitchens, sinks, showers, and laundry), and is referred to as "gray water" overseas. It is said to account for 50-80% of household wastewater, and if reused, it has been reported that the amount of drinking water used could be reduced by up to 50%. *For more details on the column, please refer to the related links. Feel free to contact us for more information.

COD (Chemical Oxygen Demand) is a measure used to assess the degree of water pollution, and with the increasing environmental awareness nowadays, measuring COD is important. On the other hand, BOD (Biochemical Oxygen Demand) is also an indicator that should be pursued, but it has the drawback of requiring a 5-day incubation period for measurement. Let's also look into whether COD can be used as a substitute for BOD. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

In Japanese plating factories (such as nickel, zinc, and chrome), compliance with wastewater standards based on the Water Pollution Prevention Act is required, and in recent years, reducing water usage and wastewater load has become important from both environmental and cost perspectives. Against this backdrop, counterflow multi-stage rinsing (counterflow cleaning/multi-stage rinsing) has been widely adopted as it can achieve both cleaning efficiency and water conservation. Counterflow multi-stage rinsing involves connecting multiple rinse tanks in series, where new water introduced into the last tank flows sequentially to the preceding stages. This mechanism ensures that parts are cleaned with the most purified water at the end of the process. As a result, it can significantly reduce water usage and wastewater volume while maintaining equivalent cleaning quality compared to traditional single rinsing or continuous spraying methods. *For more detailed information, please refer to the related links.
