Shandong Ecolink Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of wastewater treatment system in China, featured by quality products and good service. If you're going to wholesale high quality wastewater treatment system, welcome to get more information from our factory.
Product Introduction
Wastewater treatment equipment is specially designed for industrial-source wastewater, solving the pain points of chemical plants, food processing plants, electroplating plants, printing and dyeing plants and other enterprises where "wastewater discharge fails to meet standards and environmental fines continue."
Unlike domestic sewage, industrial wastewater often has characteristics such as high COD, high salinity, high ammonia nitrogen, strong acidity or strong alkalinity. Our equipment adopts a three-stage process combination of pretreatment + biochemical treatment + advanced treatment to ensure stable compliance of effluent.
Core value for buyers: one-time investment, ten years of peace of mind, completely eliminating the risk of environmental fines.

FAQ
Q: Can wastewater treatment equipment handle acidic wastewater?
A: Yes. Depending on pH value and composition, materials such as 316L stainless steel, PP, PVDF or FRP are selected, which are resistant to acid and alkali.
Q: Is the treatment effect stable?
A: Stable. Equipped with online pH meter, DO meter, and level controller, PLC automatically adjusts aeration and dosing to avoid human error.
Q: Can it be customized?
A: Yes. We customize process, materials, size, and control methods based on customer-provided wastewater analysis reports.
Q: How is after-sales handled?
A: 2-year warranty. Provide operation videos and remote guidance. Long-term spare parts supply.
Q: What is the MOQ?
A: Starting from 1 set.
Q: How long is the delivery time?
A: Standard 25–35 days, complex customization 45–60 days.
Q: Are operating costs high?
A: Electricity cost is about 0.3–0.8 RMB per ton of water, chemical cost 0.2–0.5 RMB per ton (depending on water quality). High-concentration organic wastewater can produce biogas for recovery, further reducing net cost.
Q: Does the equipment require large space?
A: Saves 40–50% space compared with traditional civil structures. Can be designed as multi-level or underground layout for limited sites.
