With the development of the world, population growth and climate change, water resources for all humankind are becoming increasingly scarce. Rational use of traditional water resources (such as inland freshwater lakes and reservoirs) and the search for new water sources have become crucial. The water treatment industry is committed to finding ways to maximize the shared use of water resources, ensuring that water supplies can meet demand for as long as possible. Aging production facilities and external water transmission pipelines within the water treatment industry bring frequent equipment repairs and waste of resources.

We provide customers with integrated solutions for every stage of the water cycle, including desalination, transmission, treatment and distribution of water sources using the most effective methods, research and discovery of new uses for recycled water, and ensuring the reliability of wastewater treatment. Through valve products and services, SUFA valves help customers optimize plant operations and pipeline facilities.

Rapid industrialization has been accompanied by severe industrial water pollution. With the rapid advancement of China's industrialization and urbanization, the types and volumes of industrial wastewater have increased sharply, intensifying pressure on surface and groundwater environments and posing a serious threat to ecological safety and residents' health. China's total water resources rank sixth in the world, but per capita water resources are only one quarter of the world average, ranking 88th among the 153 countries continuously tracked by the World Bank — the future water shortage situation in China will be very severe. The mismatch between industrialization and environmental pollution control could well bring this severe situation forward.

The 2014 Report on the State of the Environment in China shows that water quality monitoring was carried out at 968 state-controlled surface water monitoring sections (points) on 423 major rivers and 62 key lakes (reservoirs) nationwide, with Class I, II, III, IV, V and inferior-V sections accounting for 3.4%, 30.4%, 29.3%, 20.9%, 6.8% and 9.2% respectively. In April 2015, the State Council issued the Water Pollution Prevention and Control Action Plan, requiring that by 2020, the proportion of water of good quality (Class III or better) in the seven key river basins should generally reach more than 70%. In fact, with the release and implementation of the "Water Ten Plan", investment in related fields was already advancing. The construction of wastewater treatment plants is moving ahead quickly, with many localities stepping up planning and implementation. In Wanzhou District, Chongqing, 13 township wastewater treatment plants are under accelerated construction; over the following two years, Kunshan City planned to invest another 150 million yuan in rural domestic sewage treatment projects; and under the 2015-2016 eco-water-city construction tasks assigned by the Guangzhou municipal government, the city's water purification company would build or expand 4 wastewater treatment plants and initial-rainwater treatment facilities in Baiyun District.

In the face of years of problems such as direct discharge of industrial wastewater and substandard treatment, the "Water Ten Plan" explicitly called for comprehensive control of pollutant discharge, with "cracking down on industrial pollution" as its top priority task. In addition to banning "ten small" polluting enterprises and carrying out special rectification of ten key industries, centralized treatment of water pollution in industrial clusters has become a new opportunity for the environmental protection industry.

The report "2016-2020 In-Depth Research and Investment Outlook Forecast Report on China's Water Treatment Industry" released by China Investment Consulting analyzed that intrinsic demand arising from economic development and rising living standards — mainly manifested in urban renewal and upgrading, construction of mid-to-high-end residential communities, and new water treatment needs such as park and green space construction driven by higher expectations for the living environment — would mainly promote the development of the rainwater, landscape water treatment and domestic sewage treatment markets.

On the other hand, as China's environmental protection industry started relatively late, an effective water treatment equipment management system has not yet been established either in theory or in practice. In particular, enterprises producing water treatment equipment are scattered across national and local industrial departments, with no single department clearly responsible for unified management; the product market access system is imperfect and industry entry barriers are low, resulting in a mixed industry in which shell companies without production capability abound.

With the advancement of the environmental protection and water treatment market, SUFA's copper-series valves — diaphragm hydraulic control valves, remote-control float valves, adjustable pressure reducing valves, slow-closing check valves, flow control valves, pressure relief/sustaining valves, surge anticipation valves (water hammer preventers), solenoid control valves, pump control valves, differential pressure bypass valves, emergency shut-off valves, proportional control valves, flow-limiting check valves (constant differential pressure valves), filter-piston remote-control float valves, filter-piston pressure reducing valves, multifunctional pump control valves, multifunctional pressure relief/sustaining valves, resilient-seated gate valves, electric resilient-seated gate valves, anti-theft resilient-seated gate valves, combination-lock resilient-seated gate valves, manual flange butterfly valves, hydraulic slow-closing check butterfly valves, buried resilient-seated gate valves, low-resistance slow-closing check valves, low-resistance slow-closing butterfly check valves, hard-sealed eccentric half-ball valves, service inlet pressure reducing valves, proportional pressure reducing valves and other products — have seen expanded orders and inquiries from new and existing customers.
