The price of integrated Wastewater treatment equipment mainly depends on key factors such as daily treatment capacity, effluent standard, process and material. Prices vary greatly among different specifications. Below are the mainstream market price ranges in 2026 for reference (all based on standard configurations; the final quotation shall be subject to the actual customized plan).
Integrated Wastewater Treatment Equipment
Small Wastewater treatment equipment (daily capacity: 5–20 tons) is priced at 40,000–120,000 RMB per set. It is suitable for scattered rural households, small office buildings, highway service areas, etc., with relatively complete configurations and optional disinfection devices.
Medium-sized equipment (daily capacity: 20–100 tons) costs 120,000–500,000 RMB per set, widely used in residential communities, schools, hospitals and medium-sized farms. It generally adopts conventional A/O or MBR membrane processes with stable effluent compliance.
Medium-to-large Wastewater treatment equipment (daily capacity: 100–500 tons) is quoted at 500,000–2,000,000 RMB per set, applied in industrial parks and centralized township Wastewater treatment projects with customized process design.
Large Wastewater treatment equipment (daily capacity above 500 tons) costs over 2,000,000 RMB per set, mainly used in municipal Wastewater treatment and large industrial projects with complex overall configuration and high process requirements.
Why does the price of integrated Wastewater treatment equipment (click for details) with the same treatment capacity differ by tens of thousands of yuan? Here are the four core influencing factors.
Daily Water Treatment Capacity
The larger the water capacity, the higher the specification of core components such as tank body, fans, water pumps and pipelines, which naturally increases the cost. It is recommended to accurately calculate the actual Wastewater discharge before procurement to avoid inaccurate quotations caused by capacity estimation deviation.
Effluent Water Quality Standard
Class 1 Grade A is a strict discharge standard at present, requiring MBR membrane process, advanced filtration and disinfection equipment. Its price is 30%–80% higher than conventional processes, while the treated water can be directly reused. Class 1 Grade B is a common standard for domestic Wastewater with high cost performance, suitable for most rural and community scenarios. For agricultural irrigation or simple reuse standards, equipment configuration can be properly simplified with lower overall cost.
Equipment Material
Carbon steel anti-corrosion material features high cost performance, good corrosion resistance and low cost, becoming the mainstream choice for buried installation. Fiberglass reinforced plastic (FRP) is corrosion-resistant, lightweight and long-lasting with a slightly higher price than carbon steel. 304/316 stainless steel is suitable for hospitals, food factories and corrosive Wastewater environments with excellent anti-corrosion performance but the highest cost. You can select the appropriate material according to Wastewater characteristics.

Scope of Complete Set Configuration
The final price is directly affected by whether the quotation includes transportation, installation, commissioning, electric control system, disinfection equipment, filler and microbial strains. The bare unit price is relatively low, but you need to bear the subsequent installation and commissioning costs yourself, which is time-consuming and labor-intensive. Although the all-inclusive package price is slightly higher, it is more worry-free. It is recommended to prioritize manufacturers providing one-stop full services to avoid later installation and commissioning disputes.
Here are two key purchasing tips to avoid pitfalls. First, do not simply compare prices. Ultra-low-price equipment usually comes with reduced tank thickness, inferior core parts and simplified electric control systems, leading to high failure rate and expensive operation and maintenance costs in the long run. Second, prefer direct manufacturers to skip middlemen, obtain more favorable quotations and timely after-sales support. It is also recommended to require free on-site survey, customized solutions and precise quotations to ensure the equipment matches your actual demands.
The above covers the cost and purchasing notes of integrated Wastewater treatment equipment, which has been widely used in various industrial and domestic Wastewater treatment scenarios.
