Principles and Applications of MESR Green Solution

MESR Green Solution has ushered in a new age in wastewater treatment system design, not only helping to enhance treatment efficiency and reduce work area but also contributing to significant cost savings. times when compared to old technology.

What is Green Technology?

Domestic wastewater comprises a variety of contaminants, detergents, grease, bacteria, pathogenic viruses, and has a high nitrogen concentration, as is well known. If wastewater is not treated before release into the environment, it has a direct influence on water supplies and human health, has a detrimental impact on aquatic ecosystems, causes groundwater pollution, and has a variety of additional implications for future generations.

The majority of today’s wastewater treatment plants are designed with conventional thinking in mind, such as collection and then centralized treatment. They are also located away from residential areas and in accordance with natural architecture. However, this accidentally renders wastewater treatment plants large-scale in terms of both capacity and expense, as well as being out of sync with the environment and nature, resulting in waste.

When using the “green” principle to help establish wastewater treatment facilities without buffer zones or tiny buffer zones, lowering the construction area of dwellings, Green Technology is the approach utilized to solve those challenges. It reduces wastewater treatment system running costs, reduces greenhouse gas emissions, and creates green landscape design that is in tune with nature and the surrounding living area.

What wastewater treatment is Green Technology applied to?

Because urban household wastewater is frequently contaminated by organic residues, rubbish, grease, and dissolved organic compounds, green technology is prioritized for application in urban domestic wastewater treatment. COD and BOD5), nutrients (nitrogen, phosphorus…), and pathogens… The goal of a green technology solution is for microorganisms to degrade organic contaminants using the following process:

– Eliminate garbage, grease, easy-to-settle particles in pre-treatment works

– Microbial oxidation of dissolved organic matter with the use of activated sludge and fixed media Green Technology

– Sedimentation and sterilization

Green Technology may be used to treat industrial and production wastewater in addition to treating urban domestic wastewater.

Basic operating principles of Green Technology

Green technology is characterized by the use of a combination of artificial and natural substrates to improve treatment capacity, minimize sludge, and lower energy usage.

A preliminary treatment step separates residues, rubbish, grease, and crude pollutants contained in wastewater before the biological treatment stage. After biological treatment, the water is sterilized to guarantee that it meets microbiological parameters.

The complete wastewater treatment process applying Green technology will include 3 stages:

– Preliminary treatment

– Biological treatment

– Sterilize

Stage 1: Preliminary treatment

+ Coarse trash separation: Wastewater will be carried through a coarse garbage separation ditch before entering the input pump pit to remove large-sized contaminants such as branches, leaves, and plastic bags to prevent blocking the pump suction head and reducing the system’s processing capacity.

+ Fine trash separation: Wastewater will be pushed via the ditch from the inflow pump pit, where the fine garbage separator will further remove particles bigger than 5mm in diameter, reducing their influence on the processing stages. handling in the back

+ Sand and grease separation: Wastewater will be carried through a Sand Separation Tank and grease separation to remove sand and floating grease after it has been separated from rubbish + big impurities.

Stage 2: Biological treatment

The treatment cluster’s goal at this step is to address pollutant metrics like as BOD, COD, suspended solids, nitrogen, and phosphorus using a mix of Green Technology fixed biological medium and biomass. Anoxic as well as the vegetation ecosystem are suspended in the aerobic treatment tank.

The aquatic plant system is also chosen to use in the anoxic and aerobic treatment tanks for the aim of carrying oxygen to the roots to boost the activity of the biological medium while also consuming nutrients. Water contamination as a food source for growth When wastewater flow is constant, this is advantageous because tiny quantities of wastewater or low pollutant concentrations assist to sustain bacterial numbers in the system, resulting in a bigger and more diversified microbial community. Since then, green technology has shown to be more adaptable and resilient than fully activated sludge systems.

Wastewater will be transferred to biological settling tanks after being treated in aerobic and anoxic tanks to separate sludge from water. The addition of PAC coagulant here is for the goal of improving floc settling capacity and wastewater phosphorus treatment. A portion of the activated sludge will be returned to the anoxic tank for recirculation. The remainder is sent to the sludge sump and therefore eliminated from the biological treatment stage, assisting in the maintenance of a manageable sludge concentration.

Stage 3: Disinfection

After the biological settling tanks, this step is added to finish processing the residual contaminants in the wastewater before it is released into the environment. Following the previous phases of treatment, wastewater is passed through a disinfection tank to kill harmful microorganisms and ensure that the output effluent fulfills national environmental requirements. Simultaneously, the automatic monitoring system will measure and record directly the wastewater quality parameters, assisting in the control of the output water parameters and guaranteeing that column A, QCVN 14:2008/BTNMT is fulfilled before the wastewater is discharged into the environment.

Benefits of Green Technology

In terms of environmental resources:

– Green Technology helps to create wastewater treatment plants without buffer zones or small buffer zones

– Reducing the greenhouse effect because trees, in addition to treating wastewater, also perform a good photosynthetic function

– Create a beautiful landscape like a green park, the architecture is in harmony with the landscape of the whole urban area.

– In particular, it does not cause unpleasant odors like traditional wastewater treatment stations.

Economically:

– Compact factory construction area

– Large power reduction in operating costs compared to traditional technology.

Application of Green Technology

– Treatment of domestic wastewater, urban wastewater.

– Scale of the project:

+ Medium to large scale projects.

+ Projects need to save space.
