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 high purity of reverse osmosis water means that it lacks necessary minerals, which is not good for freshwater fish. Freshwater fish rely on minerals in water to maintain physiological functions, such as calcium, which plays an important role in bone development and health.

A water ozone generator is a device used to generate ozone and dissolve it in water. Ozone (O₃) is an unstable gas composed of three oxygen atoms. Due to its strong oxidizing properties, it can effectively destroy bacteria, viruses, fungi and other microorganisms in water.

Reverse Osmosis system is a highly efficient filtration technology that can remove up to 90% of dissolved solids in water, including calcium. RO uses high pressure to pass water through a semi-permeable membrane, while calcium and other impurities are blocked on the other side of the membrane.

The pore size of the reverse osmosis membrane is generally between 0.1 and 0.001 microns, which is enough to block most bacteria, viruses and dissolved ions. However, the solid particles in the mud are usually larger than this range, so in theory, the RO membrane can block these particles.

Radon gas is widely found in nature, especially in uranium-rich rock formations such as granite and shale. Radon in water mainly comes from groundwater. When groundwater passes through uranium-rich rocks, uranium decays to produce radon gas, which dissolves in the water.

The cleaning of the mini water filter is mainly concentrated in the filter element and the outer shell. The outer shell of most mini water filters can be unscrewed by rotating. Rotate clockwise or counterclockwise, depending on the design of the specific device.

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.

For some families or offices, the water demand is large, so high-flow reverse osmosis water purifiers are more attractive. Such devices are usually equipped with more powerful pumps and larger reverse osmosis membranes, which can process large amounts of water in a shorter time.

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.
