I'm interested in your sewage treatment equipment and would like to know more about the wholesale pricing. Could you please provide details on your pricing structure, including any bulk purchase discounts or special offers that might be available? Additionally, it would be helpful if you could share information on warranty options, delivery timelines, and any technical specifications that come with the equipment. I'm looking to evaluate my options thoroughly, so any extra info you can provide will be greatly appreciated. Thanks!
