Inline Wastewater Turbidity Monitoring for a Treatment Pipeline in Peru
Continuous high-precision monitoring supports faster process response and stable effluent quality
-
Project Overview
A project-support company in Peru needed continuous turbidity measurement directly inside a DN200 wastewater pipeline. The monitoring point was outdoors in a humid environment, and the customer required accurate, stable data without relying only on periodic manual inspection.
Supmea supplied an online turbidity controller and an inline turbidity probe. The system provides local indication and transmits real-time data through 4-20 mA and RS485, helping the treatment team monitor suspended-solids changes and maintain visibility of effluent conditions around the clock.

Customer Challenges
-
Install the turbidity electrode directly in the pipeline rather than use an offline sampling arrangement.
-
Maintain continuous, high-precision monitoring in wastewater service.
-
Operate reliably in an outdoor, humid environment while providing data to the monitoring system.

Supmea Solution
The solution combines the SUP-DC2000 turbidity controller with the SUP-PTU8011 turbidity probe. The probe is installed directly at the pipeline monitoring point, while the controller provides local display, signal processing, and communication with the plant monitoring system. This arrangement supports continuous visibility without depending on daily manual readings.

Recommended Products
The following related products can be presented beneath the case as website product recommendations. Final selection should be confirmed against the measuring range, installation structure, cleaning requirements, outputs, power supply, and site environment.
SUP-DC2000 Online Turbidity Controller
Recommended as the local display and signal-processing unit for continuous turbidity measurement. It can support connection between the field probe and the plant monitoring system.
Recommended for continuous turbidity measurement where the probe must operate in direct contact with wastewater. Installation and cleaning arrangements should be reviewed carefully for fouling-prone services.
Recommended as a complementary measurement where treatment performance, dosing control, or discharge quality also depends on acidity, alkalinity, or oxidation-reduction conditions.
Recommended when turbidity trends need to be evaluated together with wastewater flow, treatment throughput, or discharge volume.
Paperless Recorder or Data Acquisition System
Recommended when the project requires trend review, alarm records, or centralized storage of turbidity and other process variables.
