The monitoring constructed wetland consisted of some instruments installed at the inlet and outlet including two rain gauges, V-notch weir
with pressure sensor probe for flow measurement, data logger for recording rainfall and flow data, and spread spectrum Radio Frequency (RF) modem and Global System for Mobile communication (GSM) modem to support telemetry system.
The re-coating of the circular primary and secondary clarifier metal work includes the steel V-notch weir
plate, steel scum baffle, steel rake arm, steel skimmer arm, steel scum trough, steel center baffle, steel center support structure and steel rake arm support.
They can be used in reservoirs and drinking water storage, in rivers, boreholes, aquifers, environmental monitoring and for V-notch weir
The KUB pilot plant maintains constant flow by a sampling pump that provides excess flow to a V-notch weir
with a variable overflow.
A variety of built-in flumes and weirs for determining flow rates including Parshall flumes, cut-throat flumes, California-pipe weirs, rectangular weirs and v-notch weirs
The backfill placed inside all drainage chambers located around the site should be excavated, the drainage systems and v-notch weirs
brought back into operation and the chambers protected from public access by suitable covers.
For accurate measurement of small flows, V-notch weirs
