Harmsco Filtration Products
Filtering industrial water can enable a facility to reuse a quantity of recirculating water that improves water quality and reduces both usage and maintenance costs.
Industrial Water Filtration
There are two methods used for cooling tower systems, including side stream and full stream filtration. Side stream filtration is the most energy-friendly method of removing particulates. This method filters 3-5% the recirculation rate or allows 7-10 turnovers per day.
When considering filtration methods, the following information is needed:
Cooling Tower
- •Total volume
- •Flow rate
- •Concentration ratio
- •Recirculation rate
- •Backwash quality requirements
Facility Limitations
- •Equipment footprint
- •Desired filtration method
- •Investment
- •Backwash volume
- •Maintenance / consumables frequency
Water Quality
- •Particulate size
- •Required quality
Understanding Particle Size
More than half of the cooling tower particulates tend to be less than 10 micron which are considered small (bacteria) while 10+ microns are large. Proposed methods for testing your tower's water includes checking turbidity, total suspended solids (TSS), and particle size distribution (PSA / PSD).
Removing large particles via filtration is helpful, but a high volume of small particles contributes to high TSS. PSD can be performed by a qualified lab with a particle size analyzer, but their equipment may have limitations regarding size and sample concentration. Make-up water can have naturally occurring minerals, but factors (e.g., dust, process fluid, metals) introduced to the open-loop all play a role in fouling a system. Removing a fraction of these elements will have a positive effect on water quality and your system's health.
