The UAE has one of the highest per capita water consumption rates, despite a scarcity of easily available freshwater. Industrial Wastewater treatment is essential because sustainable development represents our best chance of preserving the planet’s health and beauty. Many concerns exist around industrial wastewater globally.
People are interested in cleaning up the contaminants in this water so that it can get for home and industrial reasons. The method may be advantageous in many ways, even if it is time-consuming and expensive. Emvees expert team will guide you in making a sustainable wastewater management process simple.
Wastewater Treatment Process
Wastewater is defined as contaminated or unusable water from the domestic, commercial, or agricultural sectors. Water treatment is the process of eliminating impurities from water so that it gets reused. This is a lengthy procedure with several stages.
STEP 1: Screening – Odour Treatment and Girt Removal
- Wastewater from households is drained into treatment plants. As industrial wastewater contains a significant quantity of chemical waste, it is collected separately from sewage.
- An odour-control treatment gets into practice in the collected water. The components discharged into the air get removed via vapor-based odor treatment.
- The liquid phase treatment eliminates odorous pollutants from the water. It gets followed by several treatment and purification steps.
- Rags, wood, plastic, oil, and other things get removed initially. As a next step, girt is removed, which consists of sand, gravel, and other materials.
- Following these screening processes, wastewater gets pumped into primary settling.
STEP 2: Primary Settling
At this point, the settled material and floating particles are pumped off. The removal of phosphorus is yet another step in this process.
STEP 3: Removal of Biological Particles
The next step involves utilizing microorganisms to eliminate suspended and dissolved biological particles. Sludge or bio-waste is produced, and this gets handled separately.
STEP 4: Disinfection & Aeration
Disinfection is the next step. This phase, also known as effluent polishing, entails the elimination of colloidal particles and, if necessary, aeration. Popular disinfection techniques include UV and chlorination treatment.
STEP 5: Sludge Treatment
The sludge generated by the biological treatment is thickened and digested by enzymes. This is then dried (dewatered) and may be utilized as fertilizer. It is not recommended for usage in food crops.
Benefits of Wastewater Treatment
Reduces wastage
The key benefit of wastewater treatment is waste reduction. Reusing water extends the life of groundwater. Wastewater is harmful to both humans and the environment. Water treatment provides both resource savings and pollution control.
Production of Energy
The industrial sector consumes a large quantity of power. As a result, energy saving is an urgent necessity. Sledge from wastewater treatment is used in anaerobic digesters to generate methane gas. This can be utilized to generate electricity for industries
Fertilizer Production
Sludge (bio-waste) from the water treatment process can be utilized as fertilizer. Industries can help to create a green environment by encouraging water treatment and the reuse of biowaste.
Optimization of Water-Based Processes
- Water treatment is a mandatory requirement to optimize water-based operations in the industry.
- Supplying enough water sources for cooling, heating, processing, cleaning, and rinsing can significantly minimize operational costs and threats.
- Eliminating organic material, metals, and other dangerous substances from wastewater allows it to be safely reused in plant operations.
- This saves money by lowering transportation and disposal expenses.
- Traditional contaminants like grease, oil, ammonia, chromium, and others are often difficult to treat.
- Proper treatment can eliminate these harmful substances from this water, allowing it to be used for industrial purposes.
Beneficiaries
Water treatment benefits all businesses. Nonetheless, certain businesses have a high demand for reused water. Water treatment saves money and provides other benefits to these industries:
Dairy Sector
The dairy industry may employ water treatment technologies to minimize waste and water usage. Cleaning, sanitization, heating, cooling, and washing outdoor spaces require vast volumes of water. Treated water is utilized to clean the outside area while avoiding contact with food products.
Food Processing Industry
Water is required in this business as an ingredient, a cleaning agent, for boiling and chilling purposes, raw material conditioning, transportation, and so on. Reusing water might be advantageous for businesses that manufacture food and beverages since waste and pollution are extensive.
Iron and Steel Industry
- A country’s iron and steel industry contributes to its economy. It also makes up a sizable portion of the toxicants.
- Water is necessary for the iron and steel industry’s cooling, descaling, processing, and other processes.
- Toxic substances like benzene, toluene, xylene, ammonia, phenols, and cresols are frequently in waste from the steel sector.
- Installing a water recovery system, however, can reduce the amount of water pollution caused by these companies. This is both eco-friendly and economical.
Breweries
Significant volumes of wastewater are produced during the brewing process. It produces solid wastes and effluent that can be handled in an environmentally friendly way at a reasonable cost, making the industry less harmful to the environment. Brewing, cleaning, and cooling procedures all need water. Discovering ways to treat brewers’ effluent can help to minimize water use and waste.
