This is a compact unit that delivers a fixed amount of treated water from the Johkasou tank to the next chamber.Adjust the flow with partitions and weirs to alleviate sudden inflows. It suppresses load fluctuations in downstream aeration, sedimentation, and disinfection, contributing to stable operation.

The main body is made of PVC, which has excellent corrosion resistance and chemical resistance, and is highly rigid, making it suitable for stable shape inside the tank. The lid is made of PE, which is chemical resistant and impact resistant, making it resistant to scratches and cracks during handling.

With a float, the inflow will stop when a certain amount of water is reached.

Without a float, the water level is not controlled, so it always flows in.
