Introduction
Variable Controlled MLE Process
This specialized MLE process can actively respond to seasonal load fluctuations and
temperature changes and is optimized for nitrogen removal. The compatible tank can be
converted into an aerobic or anoxic condition depending on the operation conditions

Features
VC-MLE
-
-
Application to existing sewage and wastewater treatment plants for process-switch to the advanced treatment -
Active response to load fluctuations and temperature changes through a variable-controlled aeration system -
T-P removal through chemical injection -
Easy maintenance through simplified process -
Energy saving through automatic control of turbo blower according to the dissolved oxygen concentration -
Maximization of oxygen delivery through microbubble diffuser

Application
01
Sewage/Septage/ Wastewater Treatment
- Treatment plant with nitrogen removal challenges
- Treatment plant with low DO concentrations and difficulty in nitrification
- Treatment plant with difficulty in changing existing structures
- Treatment plant with high power consumption due to excessive air pollution
03
Other Treatment Plant
- Sites with significant influent load fluctuations
- Sites where need adjustment due to difficulty in removing nitrogen
