Sewage treatment plants the best sewage treatment plant suppliers in Delhi collect, treat, and discharge wastewater, providing a service essential to the environment and public health. The sewage treatment plant treats wastewater from the sinks, baths, washing machines, and toilets and treats and discharges it.
Without the proper treatment, sewage will remain in the environment and contaminate the ecosystem. The plant runs wastewater through multiple treatment stages that include primary treatment, secondary treatment, and tertiary treatment.
1. Primary treatment: This step involves adding a coagulant and aims at removing grits, coarse solids, oil, and grease if they are present. It results in the sedimentation of solids and the formation of an effluent that floats above the sludge. The effluent undergoes secondary treatment where the fine solids settle out by means of bacterial activities.
2. Secondary or biological treatment: This stage converts the organic matter into stable forms via biological activities, resulting in secondary sedimentation. Trickling filters and activated sludge methods are common approaches.
3. Tertiary treatment: The effluent undergoes tertiary treatment by using UV radiation or chlorination. Other methods like sand filters and reverse osmosis may also be used instead for this stage based on the sewage nature and the effluent from secondary treatment.
Advantages of the sewage treatment plant
STP purchased from the renowned sewage treatment plant suppliers in Delhi effectively removes pollutants, contaminants, and harmful substances from the sewage water and produces clean water. The treated water fulfills various needs like agriculture, industrial, and horticulture.
1. Saves labour: Sewage is traditionally removed and collected manually. However, nowadays it is extracted, organized, and transported using technology and can be handled by fewer workers. Also, modern STP can treat huge amounts of sewage, thus minimizing the long labour hours.
2. Generate energy: Sewage contains significant amounts of organic matter that is used to generate energy. Anaerobic digestion that breaks the sludge down produces methane gas that provides power to the grid. It can also provide the energy to run the sewage treatment plant and supply power to the residential areas.
3. Producing fertilizer: The sludge obtained from the treatment carries a substantial amount of biodegradable matter, phosphorous, and nitrogen. So, when the sludge is treated sludge drying method, is a bio-degradable fertilizer, which is used for agriculture and gardening use.
4. Minimize the public health risk: The sewage treatment plant reduces the public health risk as it removes most of the contaminants from the wastewater before releasing it into the natural water stream.
5. Eco-friendly: The sewage treatment plant treats water in many ways to remove the large solid particles, harmful substances, chemicals, and microorganisms and the treated water is safe for re-use.
As a lot of investment is required for installing a sewage treatment plant, it is important to purchase the same from a reliable STP manufacturer and supplier so that you get the best quality STP that meets your needs.
