Wastewater treatment

Published: 27 Jul 2018

Wastewater treatment is a process to convert wastewater into an effluent that can be returned to the water cycle with minimal impact on the environment or may be reused.

Types of Wastewater treatment

There are two wastewater treatment plants namely chemical or physical wastewater treatment plant and biological wastewater treatment plant. Biological wastewater treatment plants use biological matter and bacteria to break down waste matter. Physical wastewater treatment plants use chemical reactions as well as physical processes to treat wastewater.

Evac wastewater treatment system

United Technical Services partners with Evac to provide Wastewater treatment systems in the region. These systems separate and neutralize organic contaminants in wastewater to comply with national and international legislation.


Evac MBR

The Evac MBR (membrane bioreactor) is an advanced wastewater treatment process that can treat all wastewater streams to current standards. 

The Evac MBR is a biological sewage treatment plant that offers advanced black and gray wastewater treatment solutions. It directly replaces traditional biological units, and with its membrane technology it easily fulfills all current and imminent treatment requirements. In some cases, effluent from the unit can even be recycled for specific uses. In the marine industry, it allows vessels to operate in environmentally sensitive areas, treating and discharging all wastewater generated by passengers and crew without threat to health or the environment. It is based on proven, very low-maintenance membrane bioreactor technology, which is capable of filtering out particles, even those as small as bacteria.
