Household water purifiers must also be environmentally friendly? Lisheng tells you why

At present, people across the globe are increasingly focused on environmental protection and sustainability. To ensure a better living environment for future generations, sustainable development has become a top priority. In the home appliance industry, many manufacturers are shifting towards "green" solutions, aiming to provide consumers with healthier and more eco-friendly products. Among these, water purifiers have gained significant recognition as part of the green appliance movement. With rising living standards and growing health awareness, the domestic water purifier market has experienced rapid growth in recent years. The number of brands and product options is expanding, and many consumers are now asking: which one should I choose? I find it quite confusing when it comes to selecting a water purifier. That’s why we’re here to share some practical tips on buying household water purifiers, with an emphasis on both environmental responsibility and cost-effectiveness. When it comes to choosing an environmentally friendly water purifier, the “waste water ratio” is a key factor to consider. Different types of water purifiers have varying levels of wastewater production. Currently, two main types dominate the market: ultrafiltration membrane water purifiers and reverse osmosis water purifiers. Reverse osmosis technology uses a semi-permeable membrane to filter out impurities by applying pressure in the opposite direction of natural osmosis. This process effectively removes inorganic ions, dissolved salts, bacteria, viruses, and other contaminants, resulting in pure water. On the other hand, ultrafiltration membranes work by allowing only water, minerals, and small molecules to pass through while blocking larger particles like suspended solids, colloids, proteins, and microorganisms. This makes ultrafiltration a gentler and more natural filtration method. One major difference between the two technologies is that ultrafiltration retains beneficial minerals and trace elements in the water, making it more suitable for direct consumption. Reverse osmosis, however, removes almost all minerals, leaving behind mostly purified water. Additionally, ultrafiltration membranes typically have a pore size of 0.01 microns and operate using water pressure alone, meaning they produce little to no wastewater. In contrast, reverse osmosis systems require electricity to function and generate a significant amount of wastewater—often three times the volume of the purified water produced. This not only increases energy consumption but also leads to higher water waste, making reverse osmosis less eco-friendly compared to ultrafiltration. From a cost perspective, ultrafiltration water purifiers are generally more economical. They have longer filter lifespans, reducing the frequency of replacements and maintenance costs. This makes them a more sustainable and user-friendly option for most households. Choosing an ultrafiltration system can help you save money in the long run while still enjoying clean, healthy water. Lisheng, a leading brand in ultrafiltration membrane technology, has been dedicated to developing and promoting this eco-friendly solution since 1992. As the world's largest ultrafiltration membrane production base, Lisheng is one of the few companies capable of independently producing high-performance ultrafiltration membranes at an industrial scale. With numerous patents in the field, their products are widely used in homes, schools, offices, factories, and government institutions. Their ultrafiltration water purifiers are praised for their efficiency, reliability, and environmental benefits.

51.2V Lifepo4 Battery

High security:
As a positive electrode material, lithium iron phosphate has a low risk of thermal runaway, and it is not easy to explode or catch fire even at high temperature or overcharge, and has a high safety.
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose, and the decomposition temperature is about 600 ° C, so even at high temperatures or overcharging, it will not collapse and heat or form strong oxidizing substances like lithium cobalt oxide.
Long life:
Lithium iron phosphate batteries have a long cycle life, usually reaching more than 2,000 cycles, and are more durable than other lithium-ion batteries.
Under the same conditions, the life of lithium iron phosphate batteries can reach 7-8 years, far more than lead-acid batteries.
Fast charging:
Lithium iron phosphate batteries have low internal resistance and can tolerate higher charging currents, so fast charging can be achieved, and the battery can be fully charged in about 1-2 hours.
High discharge rate:
Lithium iron phosphate batteries can provide higher discharge rates and are suitable for applications requiring high power output, such as power tools, electric vehicles and energy storage systems.
Environmentally friendly and renewable:
Lithium iron phosphate batteries do not contain heavy metal harmful substances, have little impact on the environment, and their materials can be almost completely recycled and reused, with high renewability
