The WTC 500 uses reverse osmosis process with multiple barriers to remove pollutants. Water is pumped through the system's single-stage (single pass) or two-stage (double pass for highly contaminated raw waters) filtration. The double pass system is optional and is necessary only for highly contaminated water conditions like after attack or industrial catastrophes.
