Water is a precious and scarce commodity. Ongoing drought conditions and additional environmental impacts are expected
to contribute to a 61 percent increase in wastewater by 2025. The United States (along with other countries
across the globe) are looking to potable reuse. This system treats wastewater in order to
achieve drinking water quality. In fact, scientists have even built a recycling system similar to
that of reverse osmosis (RO) that can turn astronauts’ urine into both clean
drinking water and energy. Systems such as this make long-distance space travel viable. However, recycled
water is currently most commonly used for nonpotable (not for drinking) purposes. Industries such
as agriculture, landscape, public parks, and
cooling water for power plants & oil refineries are just
some of the most popular fields for which the
reverse osmosis system is used.
Due to the need of reducing total
dissolved solids, reverse osmosis is one of the key factors involved in a recycling wastewater treatment plant .
The RO system relies on pressure to force a solution (in this case, water) through a membrane
that retains the solute on one side and allows the pure solvent to pass to the other side. Water used
in paper mills and carpet dyers, toilet flushing, dust control, construction activities, concrete
mixing, and artificial lakes are also great examples that benefit from the reverse osmosis system.
Every RO water filtering system
utilizes a number of pumps. Each and every one these
pumps contain mechanical
seals. Frank Jasionowicz, Colonial Seal’s product manager for
mechanical seals, knows all too well that mechanical shaft
seal failures have become one of the main
causes of pump downtime. High quality seals from Colonial Seal have improved reliability and reduced downtime in these wastewater pumps.
