Why California Emphasizes Seawater Reverse Osmosis Plant and Seawater RO System

In the past five years, California has suffered an unprecedented drought and a severe water crisis. How to improve water supply management and seek economically efficient and environmentally friendly water supply alternatives has become a top priority.

XJY's seaWater Desalination technology has gradually become an important way to solve California's water resource dilemma, bringing new hope and opportunities to the local area.

Why is there a water crisis in California?

The water crisis in California has a long history, and the situation in San Diego is particularly severe. Precipitation is scarce, groundwater reserves are scarce, and more than 80% of domestic and commercial water relies on external inputs. Long-term over-watering of the Colorado River has caused it to almost dry up, and the state government's reduction of irrigation water for farmers in the Central Valley has made the water tension worse.

XJY seawater desalination technology improves desalination efficiency by optimizing membrane materials and innovating processes. Some seawater desalination plants using this technology are already in operation to supplement local water supply. However, the cost of desalination is high, and the energy, equipment investment and maintenance costs limit its large-scale promotion. Although XJY technology has made breakthroughs in cost reduction, it still needs to be explored and improved before it can be widely popularized.

What is XJY's innovative desalination reverse osmosis technology?

XJY's SWRO technology uses the selective permeability of semipermeable membranes to allow water molecules in seawater to pass through the membrane under high pressure, while salt and other impurities are retained, thereby achieving seawater desalination.

What is the process flow of XJY’s SWRO water treatment?

1. Pretreatment: including coagulation sedimentation, filtration, disinfection and other processes to remove suspended particles, organic matter, bacteria and other impurities in seawater, and reduce the turbidity and pollution index of seawater.

2. High-pressure pump pressurization:The high-pressure pump is used to apply pressure to the pretreated seawater to make the seawater reach the working pressure required by the Reverse Osmosis membrane, which is generally around 5-10MPa.

3. Reverse osmosis membrane separation: Under pressure, water molecules in seawater pass through the reverse osmosis membrane to form fresh water, while salt and other impurities are retained on the other side of the membrane to form concentrated brine.

4. Post-treatment: Further treatment of the fresh water produced by reverse osmosis, such as adjusting the pH value, removing residual trace impurities, etc., to make it meet the water quality standards for drinking water or other water.

What are the technical characteristics of XJY’s SWRO water purification?

1. High desalination rate: Generally, it can reach more than 99%, which can effectively remove various salts and pollutants in seawater, and the produced fresh water is of excellent quality and meets the drinking water standards.

2. Low energy consumption: Energy consumption is greatly reduced, which reduces production costs and has great advantages in the case of increasingly tight energy.

3. Strong adaptability: Whether in large-scale desalination plants or in small islands, ships and other application scenarios, it can play a role and can be adjusted in scale according to different needs.

4. Stable operation: The equipment has a high degree of automation, simple operation, easy maintenance, and can operate stably for a long time.

What are the application scenarios of XJY’s SWRO water filter plant?

XJY's SWRO technology converts vast marine resources into fresh water and has found important application scenarios in many key areas.

Water supply guarantee for residents

After XJY's desalination plant is completed and put into operation, the strictly treated desalinated seawater meets or even exceeds the drinking water standard, which can meet the basic living water needs of residents such as daily drinking, cooking, washing, etc.

New water source for agricultural irrigation

After XJY's desalination treatment and allocation, it can meet the growth needs of crops with high economic value and large water demand, such as strawberries and lettuce. Water is delivered to the fields through a precision irrigation system to ensure water supply during the critical period of crops and maintain stable agricultural production.

Reliable support for industrial production

XJY's desalinated pure water can meet the water demand of high-precision production links such as chip cleaning to ensure product quality. It can be used as cooling water, reaction water, etc. in the production process, reducing the pressure on the urban water supply system.

Emergency and special scene applications

XJY's desalination equipment can be quickly deployed to provide water for firefighting operations, without being restricted by the land water supply network, and provide basic fresh water guarantee for the life and work of people in special areas.

What is the future development trend of XJY's SWRO water treatment technology?

Although desalination in California faces challenges such as cost, environmental impact and social acceptance, XJY has increased its investment and R&D efforts in desalination, promoted the healthy development of the desalination industry, and provided valuable experience and reference for solving the global water crisis.
