| | I never took a wastewater treatment class or have worked in design of such so here is a real general question. What assumptions can be made to design a wastewater treatment plan to address wastewater coming from a textile manufacturing plant? Wastewater flow, design service area, and waste characteristics are good assumptions I presume. In order to make a very conceptual design, do other factors need to be accounted for such as groundwater infiltration, etc. I apologize that this is very general, but I can always look in a book and find out, but I am interested in your opinions given that you all have more experience. |

| | Here is a couple more. What are the discharge permit requirements. Flow and nutrient flow peaks and minimums. Is it everyday or will it only be during working hours etc. What plant operational , maintenance and monitoring skills are available. What is the availability of chemicals and power and at what costs. What options are there for sludge disposal. Regards TerryF |

| | Thanks. Does anyone know a good online resource to get cost estimation data for pretreatment system (each unit processes) for textile effluent? |

Your question is pretty open-ended. What is the purpose of your inquiry?
"Textile manufacturing," itself, covers a very broad variety of processes. By that term do you mean a "cloth weaving plant," clothing manufacturing (which can be many separate processes), thread manufacturing, a "finishing" plant, a dyeing plant, etc. etc. etc. In other words, it covers such a possible variety that passing along any useful information is impossible.
"Design service area" has no application for an industrial plant, although it would for municipal treatment of domestic and/or commercial wastewater. You would certainly want to know what the waste characteristics were, operating schedule, range of flows, the treatment standards to be met, etc. You would also need to know what the costs for construction and operation might be, as well as what any residual disposal options would be.

| We can give you some assumptions, but every, underline the word, every textile facility is unique based on size, processes. chemicals used, flow, footprint available, discharge limits, discharge receiving stream, etc. Here are some very average numbers, not including color.| Average Flow (mgd) | 1.00 | | Influent BOD (mg/l) | 400 | | Influent COD (mg/l) | 1000 | | Refractory COD (mg/l) | 50 | | Influent TKN (mg/l) | 80 | | Influent Alkalinity (mg/l-CaCO3) | 30 |

| | Textile Manufacturing if it is referred to wet processing then you have to seggregate the processes taking place in the mill. Like sizing, desizing, pretreatment, dyeing and finishing. Each of the processes involved in the textile manufacturing have different load bearing on the effluent. If you tell about the processes involved in that particular mill then something precisely can be suggested. I can however suggest you a report by topic "Identification and Reduction of pollution Sources in Textile Wet Processing" by Brent Smith, Department of Textile Chemistry, School of Textiles, North Carolina State University Raleigh, NC 27965-8302 |
