美国采购需求：家庭污水处理厂、Johkasou、集装箱式污水处理厂、成套泵站

I'm looking for a package sewer plant with a capacity of 4,200 GPD that can produce irrigation-grade water. It's crucial that the system is efficient and easily maintainable, as it will be used for agricultural purposes. Please provide details on your available options, including specifications, pricing, and lead time for delivery. Additionally, I would appreciate any information on energy consumption and potential certifications, as sustainability is important for this project. If there are different configurations or upgrades available, please include that as well. Looking forward to your prompt response!
