Oil-In-Water Monitor 2410

The Aqualert 2410 Oil-In-Water Monitor utilizes a set of optical sensors to measure absorbed and scattered light in the sample stream. The measurements distinguish between oil droplets and turbidity. A microprocessor calculates the ppm oil concentration from the sensor signal which it receives. The monitor registers the concentration of oil continuously and activates alarms and valves as necessary.

Boiler Condensate Returns:

When low pressure steam is used to preheat fuel oil, any tiny leak in the heater can allow traces of the fuel oil to contaminate the condensate. The oil returns to the boiler with the feedwater. Over time, even small amounts of oil will accumulate on heat transfer surfaces causing overheating of the boiler tubes. This results in lost efficiency and in some cases failure of boiler tubes. The oil may react with the boiler treatment chemicals to cause foaming and carryover. If leakage occurs, the Model 2410 provides warning before damage occurs.

Process Cooling Water:

When a process stream containing oil is cooled, if there is a leak in the cooler, oil can contaminate the cooling water stream. Contamination can result in both pollution of the environment and loss of product. The oil-in-water monitor lets the operator know if oil gets into the cooling water.

Process Stream Monitoring:

Edible oil processing plants may use steam to aid in the extraction of oil. Regardless of whether the condensate is recycled to the boiler or sent to waste, all traces of oil must first be removed. The Model 2410 monitors the effectiveness of the separation process.

Waste Water:

Treated wastewater from oil-handling facilities can be monitored to assure that treatment processes are effective.
