Clarifiers used in Cooling Tower Water Treatment for Energy Company Looking for Water Handling Solution

Rain for Rent, Baton Rouge was given an opportunity to provide two 6-inch DV-150 Power Prime™ pumps to complement pumps from another supplier that were being used to move cooling tower water from the flume through a clarifier, then into the Mississippi River.  The competitor's pumps could not keep up with the flow so two additional DV-150s were requested.

Nuclear power facilities are required to clean cooling towers every 16-18 months. After the plant outage, Rain for Rent was given an opportunity to present our complete solutions capabilities and was awarded the contract for the plant's future pumping and piping needs.  The first exclusive project was the April 2006 outage that consisted of five phases.

Phase One:  Pump 4,000 gpm from each of the four cooling tower basins utilizing five 8-inch DV-200c Power Prime™ pumps (one for backup), fused HDPE pipe and Camlock hose.

Phase Two:  Pump 4,000 gpm from the flume to the clarifier utilizing two 8-inch DV-200c Power Prime™ pumps, HDPE pipe, and a 20-foot road crossing; down a 45º slope to a second road crossing through two 440-foot sections of HDPE pipe. The liquid was then discharged into the top of the clarifier.

Phase Three:   Pump 4,000 gpm from inside the turbine building with two 8-inch DV-200c electric pumps (one for backup) through 1,800 feet of 8-inch Victaulic pipe to the sump, where it connected with an existing 4,200-foot line to the Mississippi River.

Phase Four:  Pump clarified water to the sump for recirculation into the backup cooling tower utilizing a 6-inch HD-150 pump, a 6-inch hydraulic submersible pump, and hose.

Phase Five:  Pump cooling water within the turbine building at 400 gpm utilizing two 6-inch DV-150 electric pumps (one for backup) and stainless steel hoses.

A well engineered Solution for each system ensured successful completion of all five phases.
