Case Study: Consistent Efficiency & Lower Operating Costs with Ultipleat
Municipal Water Treatment | Global
In order to supply 700,000 residents and an influx of summertime tourists with drinking water, the Empresa Municipal Aguas de Málaga (EMASA) installed a desalination plant that came online in 2005. One major source, the Guadalhorce reservoir, is fed by a salty stream with salinity as high as 15 g/l. Overall, 80-85% of the feed water needs to be desalinated at EMASA. The original plant design called for pre-filtering to protect the reverse osmosis membranes. As regulations require, the plant regularly revisits the cost of those filters and other consumable supplies in order to deliver safe drinking water.
The design committee evaluated the Pall Water Ultipleat® High Flow filter system. The Ultipleat High Flow is an absolute rated filter that delivers a consistent efficiency that would result in a reduction of downtime for the Reverse Osmosis membranes and cost-savings.

Solution Overview
- Reduced Downtime: Superior reverse-osmosis pretreatment filtering efficiency
- Quality Filters: Reliable performance, longer filter lifetimes, and intelligently designed for easier changouts
- Reduced Cost: Combining extended filter life, less filters needed, and less labor hours for changeouts significantly reduces operating costs

The Solution
The design committee evaluated the Pall Water Ultipleat® High Flow filter system. The Ultipleat High Flow is an absolute rated filter that delivers a consistent efficiency that would result in a reduction of downtime for the Reverse Osmosis membranes and cost-savings. The Pall Water solution reduced the footprint, stock needs as well as capital expenditures for items such as pipes and valves.

The Results
The plant has achieved lifetimes as long as one year between Ultipleat cartridge replacements. In fact, because of the consistent performance of the Pall Water filters, the time between replacements has become a benchmark for the rest of the operation.
