Wastewater Treatment
in South Africa

Smart packaged MABR technology treats domestic wastewater so it can be reused for non-potable purposes, and ultimately to drinking water quality

Location:

Durban, KwaZulu-Natal

South Africa

 

Solution:

MABR smart packaged technology
treats domestic wastewater so it can be safely discharged and reused for potable and non-potable purposes

Technologies:

Fluence Aspiral™ S1 - Membrane
Aerated Biofilm Reactor (MABR)

Challenges

  • COVID-19 travel restrictions made it challenging for project managers to visit the site

  • July 2021 Civil Unrest in KwaZulu-Natal made it challenging for MEB personnel to visit the site, the plant was monitored and operated remotely

  • South Africa power shortage i.e the plant operation being affected by load-shedding

Challenge

 

In South Africa, there’s a growing demand for clean water, however local water supplies are diminishing as a result of climate change, population growth, drought and economic growth. In some regions, water is completely unavailable. To address this issue, South African municipalities are considering ways to make the most of their precious water resources.

Solution

One attractive solution to the water shortage is to treat and reuse wastewater.


MEB installed an Aspiral™ plant in KwaZulu-Natal.  The Aspiral™ achieve high removal rates resulting in very high effluent quality and the systems can easily be designed to allow even higher effluent quality if required.
The packaged plant was seamlessly installed with remote support due to COVID-19 travel restrictions.


In the second phase of the project , additional post-treatment will be added to bring the effluent to full potabilization, so residents can safely drink the water.

Results

01

After stage one (AspiralTM), the effluent is demonstrating <10 mg/l TSS and <20 mg/l BOD, compliant with South Africa’s general limits requirements of the National Water Act (1998) for discharge of wastewater into a water resource and indicating   the effluent can be used for high quality irrigation and agricultural purposes..

02

The effluent meets China’s Class 1A and California’s Title 22 regulatory frameworks

03

The client (district municipality in KwaZulu-Natal province of South Africa) was very happy with the results, endorsed the achieved operational results, and looks forward to phase two  of the project.

 

Moreover, following successful completion of phase 1, the client supports the MABR technology for consideration in future wastewater projects within the guideline of Supply Chain Management regulations.
