Transport byproduct and waste to storm drains
As temperature increases, the biological activity of the bacteria will increase
As temperature increases, the flocculation factor of the solids will increase
As temperature increases, the sedimentation tank bottom attract the solids
As temperature increases the settling rate of the solids will increase
The amount of solids that settled out will increase
The biological activity of the bacteria will increase
The flocculation factor of the solids will increase
The sedimentation tank bottom attracts the solids
Coagulation flocculation
Filtration in disinfection
Ion exchange and softening
Screening and sedimentation
To protect the local groundwater

Before or after peak demand months
Before schedule visits by regulatory agencies
When all of the operators are available to help perform this task
When receiving waters can’t assimilate the water discharges
An empty tank could float like a cork in the water surface and caused considerable damage to the tank and piping
Extra pumps maybe needed to drain the hole
Nearby Wells maybe adversely affected by draining the groundwater
The water could drain into a sewer and overload the wastewater treatment plant
By enhancing the intensity of solar radiation
By exposing the process to environmental precipitation
By preconditioning the process sludge with chemical coagulants
By protecting the drying bed from windy conditions
