Advanced treatment technologies depend on good feedwater conditions.

Before water reaches membranes, pumps, or other sensitive equipment, contaminants may need to be reduced through pretreatment.

What Does Pretreatment Do?

Pretreatment prepares incoming water for the main treatment process.

Depending on water quality, it may include:

• Multimedia filtration

• Activated carbon

• Water softening

• Chemical dosing

• Other filtration technologies

The goal is to reduce contaminants that could interfere with downstream treatment.

Protecting Membranes

Suspended solids, hardness, chlorine, organic matter, and other contaminants can affect membrane performance.

Appropriate pretreatment can reduce fouling and scaling risks while helping maintain more stable operating conditions.

More Than Membrane Protection

Pretreatment also helps protect pumps, valves, piping, and other components.

A properly designed treatment train can reduce unnecessary stress throughout the system and contribute to more reliable operation.

One Configuration Does Not Fit All

Pretreatment requirements depend on the source water.

Groundwater, surface water, municipal water, seawater, and other sources can have very different characteristics.

American Water Solutions offers pretreatment solutions including multimedia filters, activated carbon, and softeners, integrated according to project requirements.

A strong treatment system starts before the main treatment technology.
