Seeking help in calculating the wastewater volume for a water plant (urgent! ）
Thread Content
Our factory is planning to build a new wastewater treatment plant. We’re not sure how to calculate the amount of wastewater that will be generated. The factory produces mineral water, with an annual output of 400,000 tons. We would be very grateful if anyone could help us figure out how to determine the wastewater volume – any experience formulas or methods would be appreciated. Thank you.
I couldn’t find it. Could you help check it? Thank you
The wastewater you mentioned should refer to the drainage from office and living areas within the factory premises. To determine this, you can first calculate the floor area used for offices in your company as well as the number of employees, and then use the relevant outdoor drainage standards to make the calculations.
Isn’t this a simple thing? Domestic wastewater plus industrial wastewater constitutes the total amount of wastewater generated by your company. As for the wastewater generated by industry, it can be determined by conducting an investigation in the workshop; by collecting data over several days, an average value can be obtained, and adding 20% to that value gives an approximate figure. Domestic wastewater: Currently calculated at 0.25 m³ per person per day, multiplied by the total number of employees in the company. Add another 15% to the total amount, and handle the facilities accordingly. But you need to consider whether your company will still need a second phase of construction in the next 10 to 20 years. The personnel and facilities were different back then. So you can calculate it based on the actual situation. I’ll check some information at the same time, and then it can be taken care of. How about I introduce you to an environmental protection company that can help you design a plan?
Domestic wastewater plus industrial wastewater constitutes the amount of wastewater generated by your company. As for determining the design capacity, one can refer to the \"Water Supply and Drainage Design Manual\" or use empirical estimates; thereafter, adding a margin of 10%–30% to the calculated capacity will suffice.
