Water scarcity is becoming more common as the demand for water grows. The need to devise ways to ensure its long-term viability is becoming increasingly pressing. Experts are currently looking at wastewater processing as a result of technological advancements.
Wastewater treatment is a procedure for removing polluting chemicals and pollutants from water. It handles polluted waters from home and industrial locations and safely restores them to the Environment for irrigation, industrial usage, and drinking. Effective urban water management is required to attain these goals.
Advanced green technologies (AGTs) are a set of realistic approaches and materials that use non-toxic chemical processes, clean energy sources, and environmental monitoring to reduce or eliminate the negative effects of human activities. These attempts are to improve sustainability, by securing societal demands without causing further damage to or depletion of remaining natural resources.
Traditional wastewater treatment processes are costly and hard to operate and maintain. The most popular green solutions for sustainable water management are new wastewater treatment technologies, such as bioreactors and bio-filtration used by sewage treatment technology.
- Bioreactors are containers that hold bacteria and other microbes.
- Water is carried through the biofilm in bio-filtration either up-flow or down-flow, and in a continuous or discontinuous way.

1: Membrane Bioreactor Solutions - These systems combine biological, secondary, and tertiary wastewater treatment into a single process. Its goal is to lower the carbon footprint associated with sludge sewage treatment. It employs a high amount of organic and microbial removal, as well as nutrient removal.
2: Reverse Osmosis Systems (ROS) - This is a supportive treatment that is applied after the water has been pre-treated to eliminate undesired particles. For safer use, the water is desalinated using a reverse osmosis system, which provides an effective barrier against microorganisms. It makes use of a semi-permeable membrane, which is a thin membrane with microscopic pores that allows only pure water to pass through.
3: Ultrafiltration Solutions -Ultrafiltration solutions are widely employed when water is treated for drinking purposes. It employs membrane filtration, in which particles are separated from liquid or gas mixtures by a force such as pressure. Water viruses, bacteria, protozoa, and other pathogens are effectively removed because it is used for human consumption.
4: Electro dialysis Reversal - This is a desalination method in which electricity is applied to electrodes to separate salt and other particles. It is self-cleaning and therefore ideal for murky wastewater. Electrodialysis reversal has one of the best recovery rates in water-scarce settings.
