Process water

Process water is used in industrial operations such as manufacturing, cooling, or cleaning. After use, it may be contaminated with chemicals, oils, heavy metals, or other substances generated during industrial processes. Unlike stormwater, process water has distinct characteristics that influence its treatment.

Consistent flow rates

Process water typically has a stable and predictable flow, as it is continuously used and generated within industrial operations. This contrasts with stormwater, which fluctuates depending on rainfall.

Well-defined contaminants

Since process water originates from specific industrial applications, its pollutants are often well-documented. Unlike stormwater, which can carry an unpredictable mix of contaminants, process water generally contains known chemicals, metals, or organic substances.

High concentration, no dilution

Unlike stormwater, which is diluted by rainwater, process water often contains high concentrations of contaminants. This makes it essential to select the appropriate treatment methods to effectively remove these substances.

Controlled processes

Water flow and discharge within industrial processes can usually be managed and monitored. This allows for adjustments to treatment efforts and immediate action if changes occur in the water’s composition.
