Sand Stop G "Ultra Fine Separation Grating"
Solve the maintenance and management issues related to the flow of water from rainwater collection and drainage channels to combined sewer systems with "Sand Stop G"!
Combined sewer systems are facing frequent issues due to heavy rains, which cause an increase in internal pressure within the sewer, particularly placing a significant burden on the joint sections. Additionally, the inflow of solid materials such as soil, gravel, fallen leaves, and branches along with rainwater leads to a phenomenon similar to "wet blasting," where the internal walls are eroded by the water flow during heavy rains, accelerating physical deterioration. Furthermore, when there is no inflow of rainwater, chemical deterioration due to hydrogen sulfide progresses, resulting in a shorter lifespan compared to separate sewer systems. Moreover, underground infrastructure is susceptible to the effects of earthquakes and ground subsidence, and since it is buried, external inspection is difficult. Therefore, it is essential to minimize the factors contributing to internal pipe deterioration as much as possible. In the context where collaboration between the public and private sectors is required to address the maintenance and longevity of sewer systems, "Sand Stop G" plays an important role as one of the solutions. For rainwater catch basins: • Sand Stop G = KAHIRAN: 200x200 - 500x500 For U-shaped gutters: • Sand Stop G = GOMIIRAN: 200 width - 500 width
