Cooling Tower Wastewater Storage & Reuse

		Wastewater from cooling towers, also known as blow-down, can reach temperatures over 100°F as well as contain chemical residues and mineral deposits. Before this wastewater can be reused or released back into the environment, it must be treated and cooled. This is accomplished by storing the used water in a holding tank to allow the water to cool and be transferred to the next stage. Because this water may contain toxins that are harmful to plant and aquatic life, accurate measurement of the water level is critical to prevent overfilling. At this power plant an EchoSwitch II is maintaining level of wastewater in a large fiberglass tank buried underground. The EchoSwitch II is equipped with two relays; one high alarm and one low alarm, directly interfacing to a PLC for pump control.
At high alarm the pump starts and moves water to the next stage of treatment. At low alarm the pump turns off to prevent burn out and allows tank to fill again. The EchoSwitch II is perfect for applications involving local area pump control. It is a reliable non-contact level solution to replace your stainless steel float tree that will corrode or fill with sediment. "We Do Your Level Best".
