This is a set configuration of a decomposition device for nitrogen and phosphorus that can easily and quickly decompose and measure total nitrogen and total phosphorus in lakes, ponds, dams, etc., along with a spectrophotometric multiparameter water quality measuring instrument.

■Space-saving design & easy operation: Compact design approximately the size of A3 paper. After starting operation, it automatically performs standard liquid calibration and blank measurement at user-defined intervals. ■Easy maintenance: Essentially only requires reagent replenishment! The electrode activation function also simplifies electrode maintenance. ■Compatible with diverse samples: Suitable for a wide range of applications in freshwater and seawater. Measurement principle is resistant to coloring and turbidity. ■Environmental consideration: The reagents used do not contain harmful components, reducing the burden of wastewater treatment. ■Automatic measurement with a minimum cycle of 10 minutes: Capable of measuring 24-hour temporal changes that are difficult with manual analysis or laboratory equipment.

**Challenges Faced by Wastewater Treatment Plants** - High power consumption (over 50% due to aeration and mixing in reaction tanks) - DO levels fluctuate with a delay from ammonia treatment - Conventional DO control leads to excessive aeration - In combined sewer systems, DO levels fluctuate due to rainfall - Excessive addition of hydrogen donors (such as methanol) **What the Online Ammonia/Nitrate Sensor VARiON Can Do** - Clarifies the timing of nitrification completion for controlling aeration flow rate - Measures in disinfection equipment to adjust chlorine dosage - Controls the injection amount of methanol and other substances that promote denitrification = Reduction in power consumption and chemical costs

I will explain the long-term test regarding the measurement methods for COD and nitrate without the use of reagents, conducted at the Paisenberg wastewater treatment plant. The test began in early November 2015 and was carried out to evaluate the effects of seasonal changes.

In wastewater and drainage treatment, technologies for removing phosphorus and recovering it as a resource are gaining attention, and the demand for controlling and monitoring phosphate concentration is increasing. "Alyza IQ PO4" minimizes reagent consumption and can monitor phosphate concentration stably over a long period. ● High-precision measurement even in low concentration ranges ● Reduced maintenance burden ● Approximately 1/10 the amount of reagent compared to conventional products ● Equipped with self-diagnosis function for automatic reagent management ● Capable of measuring up to 2 channels

● Direct measurement of ammonium and nitrate during the process ● Automatic correction of potassium and chloride ● No sampling, no reagents required ● No calibration needed, long-term stability

The ammonia meter "AT-2000 type" using the electric titration method is a device that allows for the rapid, accurate, and easy measurement of ammonia (NH4-N) across a wide range of applications from freshwater to seawater. The measurement time is approximately one minute, and by inputting the pH and water temperature values, the concentration of un-ionized ammonia can be easily determined. The electrode activation function reduces the frequency of electrode maintenance. 【Main Features】 ■ Easy Operation → Short measurement time: about 1 minute (measurement range: 0 to 20 mg/L) → No calibration required ■ Simple Maintenance → The electrode activation function reduces the frequency of electrode maintenance. ■ Compatible with Various Samples → Wide measurement range from low to high concentrations → Accurate measurements unaffected by color or turbidity ■ Uses environmentally friendly specially developed reagents → Does not contain boron for pH adjustment * A sister model capable of automatic continuous measurement is scheduled to be launched this spring (2014). For more details, please contact us or download the catalog.

This is a set consisting of a UV-visible spectrophotometer and a decomposition device that can perform measurements based on the specified measurement method under the total amount regulation of the Ministry of the Environment.

The IQ Sensor Net system helps collect the necessary data for monitoring and controlling processes by freely combining 21 types of sensors. It supports small-scale operations with 2 sensors up to large-scale processing processes with a maximum of 20 sensors, providing optimal water quality management tailored to users. It also supports remote monitoring, allowing data to be viewed from anywhere using a smartphone, tablet, or computer as long as there is an internet connection. This enables operation from outside the facility when urgent on-site response is needed. Types of sensors: DO (marine water compatible model available), pH/ORP (marine water compatible model available), conductivity (marine water compatible model available), turbidity (marine water compatible model available), color, SS (marine water compatible model available), MLSS, ammonia, nitrate, nitrite, organic matter, sludge interface.
