Monitoring turbidity spikes at the water intake is essential for Water Treatment Plants (WTP) during rainy seasons, as sediment runoff can compromise the quality of the captured water.
Heavy rain periods vary by region. A sudden increase in water volume tends to raise the concentration of Total Suspended Solids (TSS) and alter the source's organic load. For plant operators, this scenario demands increased chemical dosing and a systemic view of process stability.
To achieve this, the use of analytical instrumentation for real-time monitoring is vital, alongside the control and transmission of data for assertive decision-making and a more efficient, safe treatment process.
Technologies for Managing Turbidity Spikes in Raw Water Intake
Digimed develops process turbidimeters focused on managing turbidity spikes at the intake, such as the self-cleaning raw water turbidimeter (TB-44A-AL).
Focused on medium and high turbidity readings, the TB-44A uses the reflectance method, protecting the optical bench and ensuring greater durability of the sensor unit, which operates between 0 to 1,000 NTU or 10,000 NTU.

From WTPs and WWTPs to complex chemical processes with explosive atmospheres (Exi), the TB-44A-AL provides the security and reliability required for online turbidity analysis. This version features a self-cleaning function specifically developed to prevent solid particle buildup inside the sensor unit.
Additionally, the TSAC-46 organic load analyzer/controller/transmitter instantly detects variations in organic matter in raw water. This allows for rapid treatment adjustments, reducing the risk of disinfection by-product formation and chemical waste.

The TSAC-46 is a robust, practical online instrument designed to monitor organic matter in drinking water or wastewater using parameters such as SAC 254, CODeq, BODeq, and TOCeq in real-time. It is based on the UV spectrophotometry principle (254 nm), operates reagent-free, and requires low maintenance. Its full plant integration ensures operational agility for fast decision-making, monitoring up to four parameters simultaneously.
To further assist in turbidity spike management, Digimed offers the AI-ZT-HP coagulant monitor, which provides an immediate response to raw water turbidity changes.

The AI-ZT-HP optimizes coagulant and flocculant dosing in drinking water treatment through a fast, automated response (without human intervention). The instrument controls dosing by measuring electrokinetic charges, cations, and free anions based on Zeta Potential. This high-quality monitor features a set-point adjustment for the coagulant in operation with a gain adjustment of up to 20x (ranging from 0.5 to 20x).
