Currently in water filtration, reverse osmosis membranes and nanofiltration membranes are the most commonly used membrane elements, but many users have a vague understanding of reverse osmosis membranes and nanofiltration membranes. Today Jun Xin will introduce to you what the differences between RO and NF membranes are, as well as the commonalities and differences. Read More

The microstructure and filtration mechanism of reverse osmosis (RO) membranes, the most efficient filter membranes for contaminant retention, has been a hot topic of research. So, is an RO membrane a porous or non-porous membrane? The knowledge and answer to this question will have a direct impact on the understanding of the filtration mechanism of RO membranes. The answer to this question is changing with the advancement of technology and the deeper analysis of the microstructure of RO membranes. Read More

Reverse osmosis membranes are now used in a wide range of industries, but do you know their origins and history? This article takes you through the history of reverse osmosis membranes. Read More

The invention and large-scale application of Reverse Osmosis (RO) is a landmark achievement in the development of modern water treatment technology. As an advanced membrane separation technology developed after the 1950s, RO has been widely used in desalination, brackish water desalination, domestic water purification and wastewater reuse, etc. In 2018, more than 11 billion tonnes of desalinated water were produced worldwide using RO technology, which could be used by 320 million people. Over the past 70 years, many important scientists, entrepreneurs and a large number of technology companies have joined forces to perform a fascinating history of the development of reverse osmosis technology.

Reverse osmosis technology is currently the highest of all water production technologies mastered by mankind, through reverse osmosis components to improve the purity of water, cleanliness of almost 100%, to remove impurities and salt contained in the water. In the selection of reverse osmosis equipment, we are mainly concerned with two indicators: the desalination rate and the recovery rate, the former determines the quality of the water produced and the latter determines the utilisation rate of the water.

Reverse osmosis membrane is the key equipment of the reverse osmosis system, the system for a long time in continuous operation, the water calcium and magnesium plasma will be constantly precipitated and attached to the surface of the reverse osmosis membrane, the formation of scaling blocking the membrane pores, which will affect the efficiency of the reverse osmosis system water, damage to the reverse osmosis membrane. As the reverse osmosis membrane is more expensive, so in the operation of the system, to increase a section of the dosing system, water treatment equipment in the water with reverse osmosis scale inhibitor, delay the precipitation of calcium and magnesium ions and membrane surface scaling.

For each membrane unit, people want it to function to the maximum, hoping for the highest desalination rate, maximum water permeability and the longest possible life. A reasonable pre-treatment is essential for the long-term safe operation of the reverse osmosis plant. Read More

Photovoltaic power generation systems can be divided into grid-connected photovoltaic power generation systems and stand-alone photovoltaic power generation systems according to whether they are grid-connected or not. Grid-connected photovoltaic power generation systems mainly refer to photovoltaic systems that are connected to the grid and receive grid dispatch, such as various centralised or distributed photovoltaic power plants. Stand-alone photovoltaic power generation systems mainly refer to a variety of photovoltaic power generation systems that operate independently of the grid, such as solar street lights, rural household photovoltaic power supply, etc. Read More

Energy has always been a topic of great concern to society as a whole. In today's world, energy is the essential basis for all productive work. Currently the most widely used energy sources are mainly traditional fossil energy sources such as coal and oil, but due to the environmental degradation and sharp reduction in resources caused by their massive use, people are increasingly expecting green energy sources and are urgently seeking new clean energy sources to replace them.

Building a solar photovoltaic power station is a very time-consuming and labour-intensive project, and the slightest carelessness may have an impact on the subsequent operation of the plant. So today we are going to introduce some of the problems in the construction of solar PV power stations, such as the impact on buildings, the environment and the power grid. Read More

As we all know, energy storage can be divided into mechanical energy storage and chemical energy storage. Mechanical energy storage can be divided into pumped storage, compressed air storage, flywheel energy storage; chemical energy storage (also known as batteries) can be divided into lead-acid batteries, nickel batteries, lithium batteries, liquid flow batteries, sodium-sulphur batteries.

An inverter is a device that converts direct current energy (batteries, storage batteries) into alternating current (generally 220v50HZ sine or square wave). In layman's terms, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of an inverter bridge, control logic and a filter circuit. Read More
