basic information

1. Advanced Treated Water Soil is home to billions of microorganisms at all times, which purify contaminants in wastewater in a short period. By supplying air to the soil and enhancing the activity of soil microorganisms, the granular structure of the soil can be maintained, resulting in consistently clean treated water. 2. Energy-Saving System The equipment used consists only of a wastewater pump and an aeration fan, resulting in very low power consumption. Compared to conventional methods, this significantly reduces electricity costs and greatly contributes to CO2 reduction. 3. Easy Maintenance with Low Running Costs This simple system combines a primary treatment tank and a soil infiltration tank, making maintenance easy. Despite the advanced treatment, the frequency of maintenance inspections is low, at four times a year or more, leading to minimal running costs and reduced lifecycle costs over time. 4. Stable System Unaffected by User Fluctuations In facilities like recreational areas where user numbers can vary greatly week to week or seasonally, conventional aerated treatment tanks may experience functional decline. However, the soil microbial membrane process maintains a constant supply of the necessary microorganisms for purification, allowing for stable advanced treatment regardless of user fluctuations. *For more details, please download the catalog or contact us.*
