Customer challenges
in water and wastewater treatment

Water and wastewater treatment are critical processes that improve the quality of water and wastewater to make it suitable for a specific end-use. They are key infrastructure elements, and securing their continuous operation is crucial to sustaining safety and sanitation in modern society.

It’s important to understand the challenges of the technology in Water and wastewater treatment plants and what are the easiest solutions to technologically challenging problems. Water and wastewater treatment plants are prone to serious power quality issues with various non-linear loads like variable frequency drives (VFDs) always operating in process control. The control circuitry of modern electrical equipment can be designed for a pure sinusoidal waveform and critical processes may be interrupted when harmonic currents created by non-linear loads distort the ideal sinewave. Operating under a distorted waveform can cause several problems, resulting in costly repairs. These include repeated equipment malfunctions, overheating of transformers, nuisance tripping, premature failure of sensitive devices, loss of operations, higher energy costs, or increased overall system downtime. Critical loads in water and wastewater treatment plants also require immunity against power outages and voltage sags.

Applications such as desalination plants, pumping stations, wastewater treatment plants, irrigation systems, etc.
