Faq Frequently Asked Question How Do You Calculate The
We recommend that the filtration rate through the sand be less than than 0.4 m 3 /m 2 /hr (or 400 liters per square meter of sand surface area per hour). The V10 concrete BSF has a surface area of 0.06m 2. Maximum hydraulic loading rate = Filtration Rate*Surface Area = 400 L/m 2 /hr* 0.06 m 2 = 24 L/hr. Now, we are interested in the peak rate.
