Application

To meet many of the tertiary quality effluent limits being discharged from secondary wastewater treatment systems an advanced wastewater treatment processes is used The TIPTON tertiary treatment system is available to meet those conditions. This filter is most often used with our secondary treatment systems. The process is called a rapid sand filtration process.

Process

The purpose of tertiary treatment is to polish up the effluent being discharged from the secondary treatment system. This process involves removing a high % of the filterable BOD5 and high % of the suspended solids. In the rapid sand filtration process, the BOD and suspended solids are strained by a mixed media filter, allowing clean effluent to pass through the filter media while the filterable BOD5 will be returned back to the secondary treatment system through the mud well system.

On many effluent discharge permits the quality of the effluent has to be greater than secondary levels. This can be accomplished with tertiary treatment. This can be in the form of a rapid gravity sand filter for BOD5 and Suspended Solids reduction and anoxic zones with oxygen control for TKN (Total amount of nitrogen being released in the effluent) reduction.

Tipton Environmental International, Inc. specializes in the manufacture of rapid sand tertiary filtration systems with flows us to 300,000 gallons per day.

The TIPTON tertiary filter system is a prefabricated factory-built unit complete and ready for easy installation at the project site. The main components of the filter system are: Tertiary filter cells, clear well chamber, backwash pumps, mud well chamber with pump, and automatic electrical controls.

Operation

The tertiary filter unit is designed for automatic operation. When the solids from the secondary treatment system are discharged they enter one of the filter cells. As these solids collect they cause the level to rise in the filtrate chamber to raise. When this level reaches a designated level, the automatic control system will air scour the filter cell causing the concentration of solids to rise to the top level of the filter media. The filtering process will continue if this concentration is insufficient to cause a backwash cycle. Once solids reach a concentration level too great for filtration, the automatic control system will activate the backwash pumps and then water wash the filter media. The dirty water is dumped into the mud well chamber and recycled back to the secondary treatment system. Once the wash cycle is complete, the filter is returned online.

Unique Features

The TIPTON tertiary filtration unit features a compact design, automatic air and water wash control system, quality components ideal for retro-fitting, ease of installation, and simple operation.
