A standard water treatment system usually consists of a pretreatment unit, a core treatment unit, a post-treatment unit, and auxiliary equipment. These parts work together to ensure that the water quality meets the expected standards.

Because it needs to pass through a semi-permeable membrane to remove dissolved solids and microorganisms in the water, the RO system has a higher water pressure requirement. A RO system requires a water pressure of 40-80 psi to operate normally, and the optimal operating pressure is around 60 psi.

Common water filtration media are: 1. Activated carbon 2. Sand filtration and gravel filtration 3. Ceramic filter element 4. Ion exchange resin 5. Ultrafiltration membrane 6. Reverse osmosis membrane Emerging water filtration media are: 1. Graphene membrane 2. Biofilter

The future industrial water treatment system needs to focus on technological innovation, intelligence, and sustainability. Advanced technology, modular design, water resource recovery and zero emissions, and data analysis will become the key to development.
