The DVS contains an internal high-flow bypass weir system which diverts excess flows around the
settling chamber, minimizing the risk of resuspension of pollutants and allowing for either online or offline configurations.
Investigation of sediment transport and flow properties that is involved during the operation of sand trap chambers is very important in order to finds out that whether components of vertical and horizontal velocities in the
settling chamber is lower than critical velocity or otherwise.
From this main circulation pump, the oil passes through a cylindrical section, a round bellows, a round-to-square transition, a five-vane diffuser, and a rectangular bend (flow distributor) before entering the
settling chamber. The
settling chamber has several screens and a honeycomb for flow quality conditioning.
It draws air from the atmosphere through a very fine mesh filter and delivers it to a
settling chamber through a well-designed conical divergence.
Dubbed a baffled bioreactor (BBR), Wang's system modifies the conventional activated sludge process by using baffles to create a maintenance-free intermediate
settling chamber for sludge return.
Veidekke will build a new
settling chamber, penstock and a power station.
The wind tunnel consisted of a blower,
settling chamber with filters and a bell mouth nozzle giving a low turbulence level in the flow.
Biologically treated TMP-water was pumped from the
settling chamber of the bioreactor by a circulation pump to the bottom of the ozonation column and ozonized.
As a final point, the waste tube where the sand and fine contaminants drop from the
settling chamber of the separator is sealed at the bottom by a small rubber flapper or dribble valve.
