[Super Sol Construction Case] Subsurface Flow Reed Bed Artificial Wetland for Purification of Dairy Wastewater
Case study of purification of dairy farm wastewater using a subsurface flow constructed wetland with reed beds at a private K ranch.
We will introduce a case study of the construction of an artificial wetland using the lightweight material "Super Sol," which is made by crushing and sintering waste glass to create a foamed glass material. This project involves the purification of dairy wastewater from a subsurface flow reed bed system. Developed through a collaboration between industry, academia, and government by the National Agriculture and Food Research Organization, this wastewater treatment system purifies high-concentration organic wastewater mixed with manure and milk from dairy farms to a level suitable for river discharge. Super Sol is used as a lightweight floating material on the surface of the wetland. It prevents clogging and provides thermal insulation, allowing for wastewater treatment to begin immediately after construction. 【Construction Case Study】 - Project Details: Purification of dairy wastewater using a subsurface flow reed bed artificial wetland - Application Category: Dairy Farming / Lightweight Floating Material / Parlor Wastewater Purification - Client: Private Sector - Construction Location: Bekkai Town, Hokkaido - Required Performance: Porous, Lightweight, Insulating For more details, please contact us or download the catalog.

Company information
"Super Sol," made by crushing and sintering waste glass, is a lightweight material with countless holes, characterized by its porous structure. It is an artificial lightweight aggregate with an irregular particle size ranging from 2 to 75 mm. There are products with varying specific gravities and water absorption rates to suit different applications. Composed of soil components, it is an eco-friendly product with an eco-mark. **Features of Super Sol:** - **Lightweight:** It is 1/6 to 1/5 the weight of soil, with a proven track record as a lightweight fill material. By combining it with crushed stone, the unit weight can be controlled between 4 kN/m³ and 11 kN/m³. - **Drainage:** It can be used as a drainage material in civil engineering and greening projects. - **Aeration and Water Retention:** It can be used as an inorganic soil amendment for greening. - **Workability:** Its lightweight nature makes it easy to handle, facilitating construction in distorted terrains and narrow spaces. Like crushed stone, it can be installed through spreading and compaction without the need for curing time or special techniques. - **Stability:** Being mineral-based and inorganic, it is physically and chemically stable and does not corrode. - **Safety:** Since it is made from naturally derived glass, Super Sol is also composed of soil components, making it a highly safe material for the surrounding environment.
