Introduction to recycled water reuse system

Drinking water: Treat recycled water into drinking water standards and directly reuse it in daily life, that is, realize direct recycling of water resources. This treatment method is suitable for areas with extremely lack of water resources, but the investment is high and the process is complex.

Domestic water: Treat recycled water to non-guided drinking water standards, mainly used for water that does not come into direct contact with the human body, such as toilet flushing water, floor car cleaning water, greening water, fire fighting water, ordinary industrial water, etc. This is the usual recycled water treatment method.

Industrial water: Recycled water reuse technology can be used to retreat industrial wastewater that meets the discharge standards to achieve industrial recycling. Through softeners, RO, EDI/mixed beds and other equipment, it can achieve the standards of softened water, purified water, and ultra-pure water, so as to save capital and protect the environment.

Common process flow chart

Main process

Physical treatment method: Membrane filtration method is suitable for situations where water quality changes are large and is used to reuse reclaimed water for industrial production water.

The characteristics of this process are: the device is compact, easy to operate, and less affected by load changes. The membrane filtration method is to use external forces to separate solvents, low molecular weight substances and inorganic ions in the separated solution pass through the filter membrane into the low pressure side from the high pressure side and discharge them as filtrate; while the polymer substances, colloidal particles and microorganisms in the solution are intercepted by the ultrafiltration membrane, and the dirty liquid is concentrated and discharged. Typical processes include: UF+RO(NF), MBR+RO(NF).

Physical and chemical method: It is suitable for situations where sewage water quality changes greatly, and is used to recycle recycled water for domestic miscellaneous water. Generally, the methods used include: sand filtration, activated carbon adsorption, flotation, coagulation precipitation, carbon softening, and ozone oxidation.

The biological treatment method is suitable for sewage with high organic content and is generally used to reuse recycled water for domestic miscellaneous water. Generally, biological treatment methods such as activated sludge method, contact oxidation method, and biological turntable are used. The above methods can be used alone or in combination, such as contact oxidation + biological filter, biological filter + activated carbon adsorption, turntable + sand filtration and other processes.

Compound process: that is, a process that combines biological treatment method, physical and chemical method, and membrane filter tank. This process is the most commonly used method for reuse of industrial wastewater from production water. Its typical processes include:

1) Biochemical treatment + sand filtration + UF + RO(NF):

2) Biochemical treatment + MBR + RO(NF);

3) Biochemical treatment + advanced oxidation + UF + RO(NF).
