You receive the machinery test report and an outgoing-inspection video. - **Materials for your water:** Carbon steel with anti-corrosion coating, SS304, SS316 or FRP — chosen for the chemistry, not the price list. - **Export-ready delivery:** Seaworthy packing, full export documents and FOB Shanghai or CIF delivery to your port. - **Support after start-up:** English manuals, video guidance, spare parts and on-site commissioning or training when you need it. ## How we work 1. Send your data (flow, influent, target, power supply) 2. Process proposal 3. Quotation and GA drawings 4. Fabrication 5. Test run with report and video 6. Shipping and commissioning support ## FAQ ### What is the minimum order quantity? One set. Most buyers order a single machine or one complete treatment line; larger projects are split into several units only when it helps transport or redundancy. ### How do I get an accurate quotation? Send the flow rate (m³/day or m³/h), the type of wastewater, sludge or waste, any lab analysis you have, the discharge or output target, your power supply (voltage, phase, frequency) and the destination port. An engineer replies within one business day with a recommended model or process and a quotation. ### Can the equipment be customized? Yes. Capacity, materials (carbon steel with anti-corrosion coating, SS304, SS316, FRP), voltage and frequency, control level (manual or PLC) and layout are configured to each project and confirmed in the drawings sent with the quotation. ### Is the equipment tested before shipment? Yes. Machines are run before dispatch and buyers receive a machinery test report and a video outgoing inspection, so you can see the equipment working before it leaves the factory. ### Which certifications do the machines have? Models are offered with CE and ISO 9001 certification; the certificates that apply to your exact model are listed in the quotation and supplied with the shipping documents. ### What warranty and after-sales support do you provide? Standard warranty is one year. Support includes online video guidance, spare parts supply and, where required, field installation, commissioning and operator training by our engineers. ### Which trade terms and shipping options do you offer? We quote FOB Shanghai, CIF to your port or other Incoterms on request. Equipment is packed for sea freight, with containerized or flat-rack shipment depending on size. ### Do you supply complete treatment lines or single machines? Both. We can supply one dewatering machine or flotation unit, or engineer a complete line from screening through biological treatment, clarification, disinfection and sludge dewatering as a single package. ## Contact - Email: inquiry@waste-water-equipment-factory.com - WhatsApp / Tel: +86 176 2154 1688 - Quotation form: https://www.waste-water-equipment-factory.com/contact/ - Company: Shanghai Mars Industrial Co., Ltd., Shanghai, China
