Although household sewage reuse is not yet popular, this trend is gradually emerging, especially in some states with relatively scarce water resources, such as California, Arizona, and Nevada. Household sewage reuse usually includes two aspects: treatment and reuse of gray water and black water.

The design of the hemodialysis water treatment system is very complex and requires multiple stages of purification to ensure that the water quality meets the standards. The main steps include raw water pretreatment, RO treatment, pure water storage and distribution, and final monitoring and control.

The names of water treatment equipment vary depending on their functions, technologies and application scenarios. From home water purifiers to industrial reverse osmosis systems to gray water treatment systems, the names and professional terms of various equipment reflect their unique roles in water treatment.

Sewage treatment plants mainly treat seriously polluted domestic sewage and industrial wastewater, with complex processes and large environmental impacts, while gray water treatment plants focus on treating less polluted gray water, with relatively simple processes and small environmental impacts.

A residential water treatment system is a treatment device designed specifically for household water, designed to improve water quality and make it suitable for drinking, cooking, bathing and other daily uses.

Grades of stainless steel are usually classified based on their composition and properties, with the most common classification standards including American Society for Testing and Materials (ASTM) standards and International Organization for Standardization (ISO) standards.

Generally speaking, a water treatment plant with a treatment capacity of more than 100,000 cubic meters/day is usually considered a large water treatment plant. This standard varies depending on the region and water treatment needs.

If the rust particles in the well water are large, a filter of 10 to 20 microns can be selected; if the rust particles are fine, a filter of 5 to 10 microns should be selected.

The faucet water filter is a small filtration device installed at the water outlet of the household faucet. It is designed to remove suspended particles, chlorine, odors, bacteria and some harmful chemicals in the water through simple mechanical filtration or adsorption.

The 2 cubic meters/hour reverse osmosis water treatment system is not suitable for ordinary families due to its high processing capacity and complex installation and maintenance requirements. For most households, a small reverse osmosis system can meet daily purified water needs。
