How can you operate STP that are underground?
Underground sewage treatment systems require little upkeep and produce water that is safe to re-use after treatment. These plants are low-maintenance and come in a range of designs. Our sewage treatment plant is corrosion-resistant, heat-resistant, and very successful at providing consumers with clean water. This underground sewage treatment system effectively treats sewage water and provides clean, antibacterial water that may be used for a variety of purposes.
Why should you go underground for constructing sewage treatment plants?
When it comes to establishing a wastewater treatment plant, the site selection method is sometimes a source of contention. Aside from the large size of a typical wastewater treatment plant, local regulations frequently mandate a constant radius of more than 300 meters surrounding the facility's operational area. Despite the huge buffer zone, land prices around a wastewater treatment facility tend to be lower due to the stink and unsightly appearance of traditional facilities. We prefer to use an underground facility as a short-term solution to strike a balance between an undesirable wastewater treatment plant, limited land resources, and environmental preservation, if situations and conditions are limited.
Operation of subsurface sewage treatment plants
1: First, the installation and commissioning personnel must open the water input and exit valves, start the equipment's water inlet lifting pump, and transfer the sewage from the regulating tank to the local residential sewage treatment equipment.
2: When the water level reaches one-half of the height of the equipment for the first time, stop the water pumping, open the fan inlet valve, turn on the fan, slowly open the fan outlet valve, and aerate the contact oxygen pool for 48 hours. Start the water intake lifting pump to add the sewage to three-quarters of the equipment, then aerate the tank for 24 hours.
3: Before continuing to transmit sewage to the equipment, the crew should touch the seasoning with their hands to see if there is a sticky sensation and examine the proliferation of microorganisms in the water body until the biofilm forms. The water volume should be gradually increased until it reaches the intended volume.
4: Monitor the growth of microorganisms in the water on a regular basis, and if any irregularities are discovered, the water intake should be monitored and corrected as needed.
5: The effluent weir must be equally collected in order to monitor the flow pattern of the water flow in the secondary settling tank. In most cases, the sludge must be released every 24 hours. When sludge is discharged, the sludge discharge solenoid valve opens, and the sludge in the secondary settling tank is lifted to the sludge pond.
6: As needed, the subsurface sewage treatment equipment adds disinfectant to the disinfection tank. To achieve disinfection, the water from the secondary sedimentation tank is sent into the disinfectant dosing tank, where the drug is partially dissolved. After around 0.5 hours in the clean water tank, the treated water meets the discharge standards and can be discharged to an outside water body.
7: Once the equipment has been debugged and tested, the system can be turned to automatic operation, and the water pump and fan can be switched to automatic operation on-site.
8: Inspect the effluent quality on a regular basis to check that the equipment is operating normally.
Advantages of Underground Sewage Treatment Plants
1: Underground sewage treatment plants operate in the same manner as conventional treatment plants, purifying water for reuse.
2: The treatment plants free the community from the nuisance of seeing and smelling waste.
3: It is environmentally beneficial because the sewage is treated discretely without exposing any residual stuff to the public.
Conclusion
Nowadays, sewage treatment plants are one of the most significant facilities in residential buildings, commercial office buildings, hotels, hospitals, resorts, and many other commercial sectors, and space constraints are a regular worry in these sectors.
Taking these considerations into account, Netsol Water can customize an Underground STP. These underground sewage treatment facilities require less maintenance and is known for producing water that is safe to re-use or discharge after treatment. These are appropriate for small communities, apartments and complexes, commercial and industrial buildings, resorts, and hotels where space is restricted and aesthetics are a priority. We can offer underground STP structures in a variety of sizes to meet the needs of our clients. We provide design and consulting services for hotels, hospitals, resorts, and other commercial sectors in order to estimate STP sizing and capacity to meet the client's needs.
