Principal Applications
Cooling Tower Enhancement
Cooling Tower Performance Enhancement
Investigations on cooling tower have shown that the quality of the water has a direct effect on the thermal efficiency of the system. On site tests in the USA have shown that filtration on a side stream basis to 10 micron can improve heat transfer by 10-15%.These test also show that the solids remaining in the system with 10 micron filtration are significant.
The use of side stream filtration can reduce heat transfer losses and improve maintainability of plant in the cooling circuit. There are a number of options to assist in this enhancement.
CrossFlow MF
This is the definitive technology to improve cooling tower performance, with filtration down to 0.45 micron and removal efficiencies of greater than 99.999% on recirculation systems , this is the best available technology, and gives significant operator benefits
- Thermal efficiencies have been shown to improve to equate to design performance with this technology,
- with the removal of solids and organics down to 0.45 micron the chemicals used can be reduced by up to 20%, with improved performance, because they are only dealing with the issues for which they are designed.
- Reduced maintenance- the use of clean cooling water can only reduce the equipment failure levels within the circuit
- Reduced risk - the correct and effect application of chemicals can reduce significantly the risk of Legionella contamination
SpinClean Disc Filters
This technology is less effective than CrossFlow but still has its place for this application. When solid loads are high, and full flow filtration is the recommended process ( generally solids generated by the process) the SpinClean is the most cost effective solution. The process generated solids can be removed for the protection of the whole cooling system. When combined with a side stream CrossFlow the ideal partnership can be achieved. The SpinClean is effective for removal down to 20 micron
For cooling tower which take the feed from high temperature processes such as in the steel industry, these are beyond the limit of the SpinClean range , and can be replaced by the use of the Pressure screen filter systems. Again these are generally used as full flow systems, but can be used as large flow side stream when the application warrants is
However filtration is only down to 50 micron and this single pass surface filter is not as effective as SpinClean. Again this can be used in combination with side stream CrossFlow to achieve optimum operational control
This technology relies on the specific gravity of the particulates being present to be much higher than that of the fluid being processed, and as such they have little use on most applications. They are particularly good when high density solids are to be removed, such process examples would be
- Removal of coarse sand and grit (but not fine sand or silt)
- Removal of hot metal scale
- Removal of lead and other high density shot
Some applications can lend themselves to the inclusion of the GDS system, were the process water is flowing under gravity to a lower level sump, the inclusion of the GDS can reduce down time and reduce the solid levels within the water collection pit. This can improve system performance and reduce maintenance on the plant generally
