Technical assistance: Power consumption in municipal sewage treatment plants
Thread Content
This post was last edited by hesonchang214 on 2012-10-27 23:01. Request for help: Does anyone among the forum members know the power consumption per ton of wastewater processed in urban sewage treatment plants? ? ? Urgent! ! ! Processing capacity: 50,000 tons to 300,000 tons, with no limit.
The cost per ton of water increases by 0.07 yuan, while the cost for aeration is over 0.20 yuan per ton of water.
For the municipal BOT wastewater treatment projects we work on, the electricity cost is 0.15–0.2 yuan per ton of water
I have a question: how much is electricity charged per kilowatt-hour?
Thank you so much, but I’m not sure what the daily processing capacity is in tons... Please help... Thanks again
I’ll ask around for you tomorrow; one is the BOT project in Guangxi and the other is the BOT project in Sichuan
The power consumption I’m referring to applies to small and medium-sized sewage treatment plants with a capacity of 50,000 to 100,000 tons per day; for larger plants, energy-saving measures such as frequency conversion control and optimized equipment selection should enable even lower power consumption.
It’s around 0.2 to 0.3 yuan; this depends on the quality of water and the requirements for the treated water. The main energy consumption comes from aeration, that is, the blowers
The power consumption per ton of water treated through frequency conversion control is around 0.15!
About 60% of the operating costs of a wastewater treatment plant are electricity costs, and 60% of that electricity is consumed by blowers.
