The PYWR series of advanced micro-electrolytic fillers is a cutting-edge multi-catalytic oxidation material developed by Puyin Runrun Company to tackle the challenges of treating organic wastewater that is difficult to biodegrade. This innovative filler is manufactured using a multi-metal alloy fusion catalyst combined with high-temperature micropore activation technology, making it a new generation of non-plate-junction, additive-free micro-electrolytic filler. When applied to wastewater treatment, it effectively reduces COD (Chemical Oxygen Demand), minimizes color intensity, enhances biodegradability, and delivers consistent, long-lasting performance. Additionally, it prevents common issues such as filler passivation and caking during operation. As a key component in the micro-electrolysis process, this filler ensures continuous and efficient reaction, bringing fresh energy to the treatment of chemical wastewater.
Longpu Yinwo Run Environmental Protection Technology Co., Ltd. stands out as one of the most professional manufacturers of micro-electrolytic fillers, with extensive experience, high customer satisfaction, and a strong repeat purchase rate.
Puyinworun doesn’t just sell a product; we offer a practical, reliable water treatment solution backed by a comprehensive technical support system. Our technology is designed to meet the real-world needs of industrial and municipal wastewater treatment.
1. How does natural water circulate?
Approximately 71% of the Earth's surface is covered by water, which is why our planet is often referred to as the "blue planet." However, only about 2.5% of this water is freshwater suitable for human use. Out of this, more than 70% is locked in ice caps and glaciers, leaving less than 1% of the total water on Earth available for direct consumption.
Natural water cycles through processes like evaporation, condensation, precipitation, and runoff, driven by solar energy and gravity. This cycle creates various types of water sources, from rivers and lakes to groundwater.
In human society, we extract large amounts of water from these natural sources for daily life and industrial use. After being used, this water becomes domestic sewage or industrial wastewater, which is then discharged back into natural water bodies. This forms what is known as the "social water cycle."
Although the volume of water involved in this cycle is small compared to the total global water supply, its impact on water quality is significant. The pollutants generated in this cycle pose serious threats to natural water systems. Water environmental protection and engineering technologies aim to address these challenges and ensure the smooth flow of both clean water and wastewater in the social cycle.
[Overview of Micro-Electrolytic Fillers]
Micro-electrolysis has proven to be a highly effective method in wastewater treatment, offering numerous advantages. Here are some of the key benefits:
(1) Long service life—up to 6 years—with minimal maintenance. The filler can be replenished periodically without the need for full replacement.
(2) Capable of treating multiple pollutants simultaneously, with a compact design, simple system structure, and easy scalability for industrial applications.
(3) Wide range of applications across various industries, including textile dyeing, electroplating, petrochemical, coking, nitrobenzene, aniline, PCB, silicone, livestock, rubber, and hydrogen peroxide wastewater. It has delivered excellent results in all these sectors.
(4) High treatment efficiency, with proven effectiveness in removing a wide range of contaminants in real-world operations.
