MARLEY WATERGARD™

Marley WaterGard Water-Saving Filtration System

Reduce cooling tower water usage and wastewater while supporting reliable system operation.

How Marley WaterGard Reduces Water Usage

Cooling towers provide highly efficient heat rejection but require water use through evaporation and blowdown. Marley® WaterGard™ pre-conditions makeup water through membrane filtration, enabling higher cycles of concentration that can reduce water usage and wastewater discharge. WaterGard works alongside existing water treatment programs and is not intended to replace water treatment.

WaterGard is ideal for facilities seeking to reduce water consumption while maintaining effective cooling tower performance.

MARLEY WATERGARD PROCESS

How Marley WaterGard Reduces Water Usage

Marley WaterGard uses membrane filtration technology to pre-condition cooling tower makeup water, enabling higher cycles of concentration and reduced water usage. By reducing the mineral content of makeup water, the system can help decrease blowdown volume and wastewater discharge while supporting reliable cooling tower performance.

WaterGard is designed to augment existing water treatment programs, helping facilities conserve water and operate more efficiently. This approach supports sustainability initiatives while maintaining effective cooling tower operation.

Treats Cooling Tower Makeup Water

WaterGard pre-conditions incoming makeup water before it enters the cooling system, improving water quality and enabling more efficient operation.

Removes Dissolved Minerals

A membrane filtration process physically rejects minerals such as chlorides, calcium carbonate, and silica that commonly contribute to scale and water quality limitations.

Enables Higher Cycles of Concentration (COC)

With fewer dissolved solids in the makeup water, cooling towers can safely operate at higher cycles of concentration without increasing scaling or corrosion risks.

Reduces Blowdown Requirements

Higher operating COC means less water must be discharged through blowdown, reducing wastewater generation and treatment chemical losses.

Lowers Overall Water Consumption

Because less blowdown occurs, the system requires less replacement makeup water, helping facilities significantly reduce total water usage.

Delivers the Same Cooling Performance with Less Water

WaterGard helps facilities maintain reliable cooling performance while potentially reducing water usage by up to 59% and wastewater discharge by up to 88%, depending on source water quality.
