Large municipal reclaimed water systems are being linked to industrial zones and urban landscaping initiatives to improve water distribution and maximize the potential for reuse. Important national and technology suppliers are Veolia, Suez, Xylem Inc., Pentair, OriginWater, and Beijing Enterprises Water Group, which provide cutting-edge treatment technologies, membrane solutions, and smart water management systems. These businesses cater to both public and industrial sectors with unified solutions for effective water reuse. There are considerable prospects in China because of swift urban population increases, industrial growth, and stricter environmental laws. Funding in hybrid treatment technologies, digital monitoring, and intelligent water networks presents significant market opportunities.

China water recycle and reuse market by technology is divided into primary and secondary. In China, the advancement of wastewater treatment technology has progressed swiftly as part of a national strategy aimed at managing pollution and fostering economic growth. At the core of wastewater treatment are primary treatment techniques, which utilize physical methods like screening, grit extraction, and initial sedimentation to eliminate larger solids and suspended materials from raw sewage. These procedures decrease the initial solid burden and safeguard downstream equipment, yet have little effect on dissolved organic pollution levels. Primary treatment facilities are common throughout China’s municipal and industrial plants, especially in older establishments that were constructed before more modern designs, and act as vital pre-treatment before biological methods commence. Moving beyond primary methods, secondary treatment which biologically decreases organic pollutants is now the main focus of China’s technology landscape. The majority of wastewater treatment plants (WWTPs) across the country utilize biological techniques such as activated sludge, oxidation ditches, anaerobic–anoxic–oxic (AAO) methods, and sequencing batch reactors (SBR) as fundamental secondary processes. These systems facilitate the breakdown of biochemical oxygen demand (BOD) and chemical oxygen demand (COD) by microorganisms, aiding treated water in meeting stricter discharge criteria established by national environmental authorities. By the end of the 2010s, approximately 89% of China’s WWTPs combined mechanical and biological treatment, with an increasing number implementing more extensive nutrient removal to lower nitrogen and phosphorus concentrations. A smaller yet expanding fraction of facilities uses tertiary treatment and advanced methods like membrane bioreactors (MBRs), constructed wetlands, and chemical polishing to eliminate persistent pollutants, pathogens, and nutrients that secondary approaches may not sufficiently tackle. These techniques are especially crucial in urban areas with limited water resources and in delicate ecosystems where reclaimed water is reused for agricultural irrigation or industrial cooling.

China water recycle and reuse market by application is divided into industrial, agriculture, municipal, commercial and residential. Within the industrial sector, wastewater often arises from operations in chemicals, textiles, steel, petrochemicals, and mining, often containing significant levels of organic pollutants, heavy metals, and intricate chemical substances. To adhere to environmental standards and avoid fines, industrial facilities typically establish on-site pretreatment systems that incorporate physical separation, chemical oxidation, and biological methods prior to releasing water into municipal sewer systems or nearby bodies of water. This pretreatment diminishes toxicity and ensures consistent effluent quality so that municipal treatment plants can manage it without impeding their operational efficiency. In farming practices, the demands of wastewater are closely linked to the needs for irrigation and managing nutrients. The agricultural industry in China produces excess water that contains high levels of nitrogen and phosphorus, which pose risks of eutrophication in local watersheds. Although centralized wastewater treatment plants generally do not handle agricultural runoff directly, natural systems such as engineered wetlands and integrated rural treatment facilities are being utilized more often to clean irrigation return water before it is discharged or reused. Furthermore, in areas with limited water supply, treated municipal wastewater is deliberately repurposed for agricultural irrigation under strictly regulated conditions, making wastewater treatment a crucial aspect of sustainable agriculture methods. Urban wastewater, produced by homes, educational institutions, and public facilities, constitutes the primary workload of China’s city treatment systems. Municipal wastewater treatment plants usually provide basic and advanced processing, with many larger cities increasingly adopting tertiary treatment to meet strict standards for discharge and reuse. Rapid urban growth has led to the expansion of municipal infrastructure, including enlarging sewer systems and constructing new treatment plants to accommodate rising populations.

China water recycle and reuse market by water source is divided into municipal wastewater, industrial wastewater, agricultural drainage and stormwater runoff each bring unique challenges for managing water quality and resources. Municipal wastewater the largest volume treated in urban areas encompasses sewage from homes, institutions, and city services. China has built thousands of municipal treatment facilities, increased capacity and expanding sewer systems to accommodate the needs of growing urban populations. Industrial wastewater differs in makeup depending on the sector chemical, textile, and heavy industries produce effluents with complex pollutants that can surpass the capability of municipal systems. Regulations stipulate that industrial sites must pretreat such wastewater before it can be released into public sewer systems or directly into the environment. Companies use specialized methods including chemical oxidation and biological nutrient removal to ensure that effluents comply with permit regulations, minimizing environmental risks and protecting infrastructure downstream. This targeted approach corresponds with national objectives to reduce industrial pollution and promote sustainable production methods. Agricultural drainage including runoff from fields, farm operations, and irrigation return water carries sediments, fertilizers, and agricultural chemicals into surface water bodies. In response to these challenges, China implements nature-based strategies like engineered wetlands and retention basins that filter pollutants and encourage natural processes, helping to decrease nutrient loads and protect rural waters. Moreover, the reuse of treated municipal and industrial wastewater for agricultural irrigation helps to preserve freshwater resources in dry areas. Stormwater runoff, particularly in city locations, mixes rainwater with pollutants from urban environments (such as oils, heavy metals, and dirt) and can surpass the capacity of sewer systems in times of heavy rain. China has implemented sponge city programs incorporating permeable surfaces, green swales, and localized storage to collect and manage stormwater at its source, lessening flooding and enhancing the quality of runoff before it reaches treatment facilities or natural water sources.
