Did you know that we’re making great progress in Wastewater Treatment Plants?
This is a big step towards creating a cleaner and more sustainable future!
With more people on the planet and increasing environmental concerns, there’s a growing need for effective Wastewater Treatment Plants that don’t harm the environment.
The WOG Group has extended the use of its industrial water treatment technology. The systems ensure that no water will be wasted and that the ecosystem won’t be harmed. We are committed to creating long-term remedies for commercial wastewater discharged into aquatic environments.
They’re using state-of-the-art filtering techniques and resource recovery methods to remove contaminants and save valuable resources like energy and nutrients. Not only does this help the environment, but it also saves money and contributes to a circular economy where waste is treated as a resource.
Importance of sustainable wastewater treatment
There are several benefits of Sustainable Wastewater Treatment. Some of them are listed below:
- It protects public health by removing pathogens and contaminants from wastewater before releasing it into the environment. This prevents the spread of diseases.
- It prevents pollution of water bodies like rivers, lakes, and oceans. Untreated wastewater contaminates water sources.
- It ensures the availability of clean water resources. Sustainable treatment helps in recycling wastewater for various purposes like agriculture, industrial use etc.
- It complies with environmental regulations. Proper treatment as per standards is necessary.
- Also, supports environmental sustainability goals. Newer technologies optimize resource usage and reduce carbon footprint.
Discuss Traditional wastewater treatment methods
Traditional Wastewater Treatment Methods:
Primary Treatment:
- It screens out large particles via meshes/bars and settles sludge via sedimentation tanks.
- It removes 30-35% of Biological Oxygen Demand (BOD) and Total Suspended Solids (TSS).
Secondary Treatment:
- Biological processes like activated sludge treat dissolved and suspended waste.
- Microorganisms break down organic pollutants further removing 80-90% BOD and TSS.
- Common variations are extended aeration and trickling filters.
Tertiary Treatment:
- It polishes the effluent further to remove nutrients like nitrogen, phosphorus and residual contaminants.
- Several processes include chlorination, sand filters, membranes, and lagoons.
- Meets stringent discharge limits for reuse in various non-potable applications.
- This also ensures wastewater receives multiple stages of treatment before being safely released or reused.
Membrane bioreactors (MBRs) for enhanced treatment efficiency
Here are some key points about membrane bioreactors (MBRs) for enhanced wastewater treatment efficiency:
- MBRs combine a suspended growth bioreactor with a solid-liquid separation process using a membrane filter (microfiltration or ultrafiltration).
- The membrane replaces the sedimentation process in conventional activated sludge, allowing much higher mixed liquor concentrations (10-15 times more biomass).
- This results in a smaller footprint for bioreactors as the bacteria growth is not constrained by settling requirements.
- MBRs can achieve very high-quality effluent with around 99.9% removal of total suspended solids and biological oxygen demand.
- They also remove chemical contaminants, pathogens, parasites and viruses from water down to sizes of 0.1 microns, producing almost drinking water quality.
- Being a completely mixed system, MBRs are less affected by variations in flow and are tolerant to shock loads.
- They provide flexibility in loading several wastewater streams together in one reactor.
- MBRs have lower sludge production due to the retention of solids in the mixed liquor for longer retention times.
- The membranes require periodic cleaning but result in overall reduced energy usage compared to secondary treatment.
Why Is a Wastewater Treatment Facility Necessary?
ETPs employ various techniques to remove all dangerous pollutants from the water. In effluent treatment plants, some contaminants are heated in addition to being treated chemically and biologically. Our experts’ knowledge and experience enable them to provide trustworthy water filtration solutions. Before releasing water into the atmosphere, it is necessary to remove all hazardous compounds using wastewater treatment plants. Government guidelines for the treatment of industrial wastewater stipulate that recycling is a must for all businesses. ETP establishment in the industry is currently necessary. Nowadays, wastewater from ETPs is put in for many different purposes.
The Price of a Facility for Purifying Wastewater
When estimating the cost of wastewater purification systems, there are numerous factors to consider. If the plant runs consistently at a lower flow rate, the building costs of the wastewater treatment system should go down. A wastewater treatment plant installation typically costs between 3 and 5 lakhs. If the plant runs more often and with a higher flow, the equipment’s capital cost will usually be higher. As a company, it nonetheless contributes to preserving the ecosystem for the next generations. Solutions combine high output, low operating costs, energy efficiency, and little environmental impact. The cost of wastewater treatment services varies depending on geography and the types of industries in which they must be implemented, so it is advisable to consider all the variables involved in building the system and put this into your budget. Finding sources of renewable energy is its main objective.
Energy-efficient wastewater treatment processes for industries
A large amount of wastewater is produced by industries, and this wastewater needs to be treated to comply with environmental standards and save water resources. Industries can minimize their environmental impact, cut operating costs, and consume less energy by implementing energy-efficient wastewater treatment procedures.
The following are a few typical industrial applications for energy-efficient wastewater treatment processes:
-
Membrane bioreactors (MBRs):
MBRs do not require secondary clarifiers because they integrate biological treatment and membrane filtration. More bioretention systems (MBRs) can produce high-quality wastewater with less area requirement than traditional activated sludge systems. In addition to allowing for the recovery of clean water for industry reuse, the filtration process lowers the energy consumption linked with aeration.
-
Anaerobic digestion:
As previously stated, anaerobic digestion is the breakdown of organic matter without the presence of oxygen. High-strength organic wastewater streams, such as those produced in brewers, distilleries, and food processing facilities, are frequently treated with it. Biogas is produced by anaerobic digestion and can be collected and utilized as a renewable energy source for treatment plants or even other industrial processes to provide heat and electricity.
-
Sequencing Batch Reactors (SBRs):
SBRs are a type of biological treatment method that uses less energy and can achieve high treatment efficiencies in batches. Aeration, settling, and decanting are just a few of the treatment processes that these systems incorporate into a single tank. Energy-intensive processes, like as aeration, may be optimized and operated with flexibility thanks to SBRs.
By carrying out more research and development, we give our professionals the capacity to continuously improve water filtration. Industrial effluent water treatment is currently very important since different industries produce different toxins. Environmental contamination increases when industry develops and grows. They require a specific form of cleanup for wastewater. Clean water is discharged into the ecosystem to stop chemical pollutants from damaging it. Different harmful or non-biodegradable industrial effluents are common, depending on the industry.
