Water is a renewable resource, but sometimes it is necessary to treat it so that it can be used again. The tertiary water treatment is the process of converting the used or dirty water into something that is suitable for what you need for the next use or even returns it to its natural state. Turning wastewater into something reusable is a complicated process and can only be done correctly in a facility such as wastewater treatment systems. This type of treatment removes all solids, bacteria, plants, inorganic compounds, organic compounds, and algae to turn it into environmentally acceptable water that can even be used as drinking water once it has passed through all the different levels of filtration.

The Process of The Water Recycling System

There is a step wise process that can recycle the water by the industrial wastewater treatment, and here is this

1. The Pre-Treatment

Pre-treatment is the process that removes all large easily removable objects. The types of waste that are removed during pre-treatment include fats, oils and fats, sand, gravel, rocks, rags, and feminine hygiene products and any other larger solid that can be easily filtered, and you can trail the industrial wastewater treatment.

2. Primary Wastewater Treatment:

In the first stage of processing, wastewater flows through primary clarifiers that are large tanks. The Wastewater Treatment Plant Design is made as these tanks are large enough for the mud to settle and all the floating material such as grease and oils rise to the surface where they can be skimmed. They are equipped with mechanically driven scrapers that drive accumulated sludge to a hopper.

3. Secondary Wastewater Treatment:

Secondary treatment is where wastewater from human waste, food waste, soaps, and detergents are decomposed and composted through an aerobic biological process that speeds up the process. This bad water treatment plant design is like, After composting, it goes through a series of filters that cleanse all the other little things like bacteria and algae. There are several different types of filters, including a drip filter and aerated biological filters. Drip filters are where sedimented wastewater liquor is spread over the surface of a deep bed made of carbonized coal, limestone chips or a specially fabricated plastic medium that has large surface areas to support the bio films that form. The liquid then passes gradually through the purifying medium to filter all the biological films of bacteria, protozoa, and fungi. The last steps of the filtration process are the filtration of sand, which also eliminates the residual matter and the filtration of activated carbon that eliminates the toxins that remain in the liquid.

4. Nutrient Removal and Disinfection:

Wastewater has the nutrients such as nitrogen and phosphorus, which can be very harmful in large doses in future. Nitrogen is removed by oxidation, which converts it into nitrate and then nitrogen gas that is removed from the water by releasing it into the air. Phosphorus is eliminated through the use of chemical products such as iron or aluminum salts.

The final step that the water goes through is the disinfection stage in which chlorine or ultraviolet light is used to disinfect the water and prepare it for human consumption. With this last step, the water turns from contaminated liquid into useful and clean water.

Many industrial water treatment systems, follow this process to recycle the water through the wastewater treatment plant.
