We will perform well cleaning and maintenance of the pumping pump to ensure comfortable water lifting. 【Maintenance of Water Lifting Wells】 ◎Diagnosis of Well Clogging We use a camera directly in the pipe to check the level of dirt inside the well. We mainly check the degree of dirt accumulation and blockage at the strainer section (where water is extracted). Additionally, we also determine well clogging through pumping tests. ○Brushing We use a brush to move up and down and rotate at the strainer section to remove dirt attached to the well wall. ○High-Pressure Cleaning We attach a cleaning nozzle to a high-pressure cleaner to wash the well wall at the strainer section. ○Air Lift We send compressed air and water to collect the scale accumulated at the bottom of the well pipe along with the water. ○Water Lifting We collect fine mud at the bottom of the pipe along with water.

Our company provides a one-stop service for burial treatment, from investigation to disposal, handled by professionals. 【Investigation and Measures for Buried Waste】 ◎ Searching for and locating buried items (identifying burial sites using buried object detection technology) We apply buried object detection technology to identify burial sites. Depending on the characteristics of the buried items, we utilize various detection methods such as ground-penetrating radar, electrical surveys, and metal detectors. ◎ Identifying burial depth through boring surveys Based on the results of the buried object detection, we determine the boring locations and identify the burial depth. We analyze the buried items obtained through boring and consider disposal methods, as well as assess potential soil contamination in the surrounding area if hazardous substances are present in the buried items.

**Overview of Multispark** ● Evolution from Traditional Technology To shorten the time required from ignition to the completion of the combustion cycle, the traditional method of combustion in gasoline engines accelerates gas flow through compression and swirling. Most engine types have only one spark plug that generates a spark and ignites the flame, which limits the spread of combustion throughout the combustion chamber and the combustion rate. However, to use multiple ignition sources, the optimal layout of the intake and exhaust valves in the combustion chamber must be compromised. ● Simple Configuration with Minimal Additional Requirements The Multispark system appears to be just a slightly thicker cylinder head gasket. Therefore, it does not require significant changes or special equipment for implementation. This configuration allows for the existing head gasket to be replaced with the Multispark unit, providing advantages or rapid combustion. The number and position of ignition points can be easily modified to fit many engine designs and adapted accordingly.

**What is Low-Concentration PCB Waste?** Low-concentration PCB waste refers to PCB waste with a concentration of 5,000 mg/kg or less, most of which consists of insulating oil and electrical equipment such as transformers. According to the law (Special Measures Law for the Proper Disposal of Polychlorinated Biphenyl Waste), it must be processed by a specified deadline. Furthermore, in order to process it, it must be entrusted to a specialized processing contractor that has received certification and permission. Depending on the specifications of the contractor, the method of transportation, the shape and weight of the waste, and the condition of the casing, adjustments to the packaging may be necessary.

**Disposal of X-ray Equipment Using Beryllium** - **Physical Properties and Uses** Beryllium has a low atomic weight and density among metallic elements, giving it a high permeability to X-rays. It is used as metallic beryllium in X-ray tube windows and X-ray detector windows in X-ray equipment. - **Treatment and Disposal Methods** Considering the risks associated with beryllium dust, our company dissolves the relevant parts and then performs neutralization and dehydration treatment (insolubilization treatment). **Isocyanate Compounds** - **Physical Properties and Characteristics** Isocyanates are compounds that contain isocyanate groups (R-N=C=O) and come in various types. They are used in many industrial products as raw materials for paints, adhesives, and polyurethanes. - **Risks** Due to their very high reactivity, isocyanates undergo polymerization reactions with water, alcohols, amines, etc., which are exothermic and result in solidification. Therefore, they require careful handling, including avoiding heat, light, and moisture, storing in sealed containers under refrigeration, or using inert gas for storage. - **Treatment and Disposal Methods** Given the risks of reactions with other substances leading to solidification and gas generation, our company has established a dedicated processing line for incineration to ensure safe treatment.
