At a certain headloss, the pulse cycle starts. The effluent valve is closed, but the influent remains open. The backwash pumps force air trapped beneath the underdrain up through the filter bed while additional air is introduced above the bed by a series of diffusers. After about 20 seconds, normal filter operation resumes. equation balancer with work
