APPLICATION
Stormwater management is the practice of controlling and directing rainwater runoff to prevent flooding, erosion, and water pollution.
PROBLEM
Stormwater can carry pollutants like sediment, oil, heavy metals, and nutrients that degrade water quality. Discharge limits, monitoring, and treatment requirements are set by environmental regulators to ensure stormwater meets water quality standards before entering natural bodies of water. Some systems use chemical treatment (e.g., coagulants) to bind and remove pollutants. These systems need to be highly automated and flexible to account for changing conditions. Poorly managed systems can result in environmental or infrastructure damage, with heavy fines for operators.
SOLUTION
Walchem’s Intuition-9 controller can facilitate the entire stormwater management process.
One example involves a municipality who manages stormwater in large underground vaults. The Intuition-9 continuously monitors influent and effluent pH, as well as final effluent residual polymer and turbidity. EWN dosing pumps with PosiFlow feed verification automatically dose flocculants and coagulants into the settling basin. If the final effluent is within limits, discharge is permitted. If the final effluent is out of spec, it is returned to a holding vault for further treatment. The Intuition-9 controller is used in conjunction with ultrasonic level sensors and variable frequency drives to control the water level in the stormwater holding tank and the settling basin. The Intuition-9 controller is also used to collect critical process data providing proof of compliance to the client and regulator.
The result is improved water quality and environmental protection with reduced chemical usage.
