Before we move forward, we need to understand the meaning of sewage treatment plant water. A STP plant is a process of removing contaminants present in the wastewater. Sewage water is released from households and industries. It contains a high amount of organic and inorganic matter. Therefore, it needs to be treated before it is discharged into the environment.
Sewage treatment plants include various biological, chemical, and physical processes to remove the contaminants and produce environmentally safe treated wastewater. The treated water from sewage can be utilized for various purposes. Various purposes include landscape irrigation, car washing, and flushing. The advantage of doing this is to reduce the consumption of freshwater.
But it should be kept in mind that the wastewater must be treated properly. Otherwise, it will do more harm than good. The idea behind this is very simple. The sewage wastewater contains organic and inorganic matter such as nitrogen, phosphorus, and biological impurities, which are very harmful. High salinity levels are detrimental to irrigation and gardening. It promotes water retention and affects the growth of plants. It is associated with promoting corrosion.
In STP, pH, organic matter, nitrogen and phosphorus are treated. Total dissolved solids, i.e., the salinity of the soil, are not treated. Therefore, to achieve clarity, the treated water needs to pass through the disinfection unit. Chlorine or ozone is very effective for killing bacteria.
Therefore, the water needs to be treated properly, and it must be clear, colorless, odorless, and free of suspended material. Apart from this, it should also be pH neutral, meaning thereby its pH should be in the range of 6.5- 8.5. If treated sewage water is used for irrigation purposes, it can considerably prove beneficial to the plant’s health and soil quality. It can also decrease the necessity of using fertilizers. It improves the physical properties and nutrient content in soils. Overall, properly treated sewage water is extremely useful for irrigation and gardening purposes since it helps improve the health of plants and soil.
Apart from gardening, it can also be used in the process of flushing after proper treatment. Otherwise it will damage the metallic mechanism of flush tanks and reduce the metallic life of metallic pipes. Therefore, an even RO system will be required to treat the STP water. A simple thing to remember is to treat the water before reusing or recycling it. Reusing and recycling are good and conservative steps towards the environment. But, precautions are needed to avoid the problems faced if it's not treated well.
