Control periods when plants are unmanned
Many water treatment plants still use manual control for coagulant dosing (usually alum or ferric). Whilst the raw water quality is steady this is an effective method to set a coagulant dose, however, when the raw water changes then manual control of the coagulant dose breaks down, particularly when plants are unmanned overnight or over…

Dissolved Oxygen Monitor Offers ‘AutoClean’ and ‘AutoVerify’ to Reduce Sensor Fouling
Dissolved Oxygen Monitor Offers ‘AutoClean’ and ‘AutoVerify’ to Reduce Sensor Fouling The most common application for a dissolved oxygen (DO) controller is an aeration lane in a wastewater treatment plant. The harsh environments that the DO sensors operate in almost inevitably lead to sensor fouling, and sensor drift as a result. Controlling the level of…

Online Conductivity Meter to Monitor Pure Water Production
Online Conductivity Meter Installed to Monitor Pure Water Production Conductivity is the ability of a solution to transfer (conduct) electrical current. The value of the electrical conductivity is dependent on the ability of electrons or other charge carriers to move within a liquid. The inverse of this is resistivity. Resistivity describes the ability of a…
