Reclaimed water, also known as reclaimed water, is the treated sewage to make its quality meet certain use standards and meet the needs of non-potable areas. This concept is originated from Japan. Tap water is called "water supply" and sewage is called "sewage". The quality of reclaimed water is between the two, so it is called "reclaimed water". The reclaimed water is of great significance in solving the problem of water shortage. Its stable, reliable, economical, efficient and environmentally friendly characteristics make it an important part of future water resources management.

Industrial wastewater recycling

Municipal sewage recycling

The purpose of municipal sewage recycling is to alleviate water shortage and realize sustainable utilization of water resources. The municipal sewage recycling can not only reduce the dependence on natural water resources, but also reduce environmental pollution. It is an important way to achieve green, recycling and low-carbon development.

Recycling of high-salt wastewater

High-salt wastewater refers to the mixture with the total salt content ≥ 1% by mass. Concentration above 10 g/L is high brine based on NaCI content.

Technical advantages of industrial wastewater recycling

① High-efficiency and energy conservation: significantly reduce the treatment cost by optimizing the process flow and adopting high-efficiency and energy conservation equipment;

② Resource conservation: zero discharge of wastewater, reduction of water consumption and environmental pollution;

③ Environment-friendly: comply with national and local environmental protection policies and promote green development and social responsibility of enterprises.

Technical advantages of municipal sewage recycling

① High-efficiency treatment: the combination of biological treatment and membrane technology improves the removal efficiency of pollutants, and the effluent quality is stable and reliable;

② Resource conservation: the consumption of natural water resources is reduced through recycling, and the production and treatment costs of sludge are reduced at the same time;

③ Environmental protection and low carbon: reducing environmental pollution and carbon emission, meeting the requirements of green, cyclic and low carbon development.

Technical advantages of high-salt wastewater recycling

① High-efficiency demineralization: remove salt in water, produce high-quality reclaimed water and realize recycling of water resources;

② Recycling: create economic benefits through recycling and reutilization of industrial salt;

③ High-efficiency process: optimize the process flow and use high-efficiency and energy-saving equipment to reduce the treatment cost;

④ Strong adaptability and flexibility: the process design meets different water quality conditions and discharge standards, and adapts to a variety of scenarios;

⑤ Modular design: the equipment adopts modular structure, with small floor area and easy installation and maintenance;

⑥ Sustainable benefits: improve resource utilization rate, reduce energy consumption and emission, and promote environmental green development.
