The polypropylene Hakaiden packing produced by Dier Chemical Packing Co., Ltd. in Pingxiang City, Jiangxi Province is an efficient biological carrier packing designed specifically for the biological desulfurization tower of kitchen waste biogas purification systems. It is made of high-quality polymer materials and special processes, with a large specific surface area, high porosity, and excellent biological affinity, which can greatly improve adhesion and metabolic efficiency, and achieve efficient biological desulfurization.

1、 Core characteristics of polypropylene Hakaiden filler

1. Efficient desulfurization performance

Specific surface area ≥ 800m ²/m ³, porosity>95%, providing sufficient growth space for microorganisms.

2. Strong durability

Acid and alkali resistant, anti-aging, long-term stable operation in pH 1-9 and high temperature (≤ 60 ℃) environment, with a service life of many years.

3. Low resistance design

Three dimensional structure optimizes airflow distribution, with a pressure drop 30% lower than traditional fillers, reducing energy consumption.

4. Green and environmentally friendly

Non toxic and harmless, supports natural microbial biofilm formation, and has no secondary pollution.

2、 Technical parameters of polypropylene Hakaiden filler

3、 Application scenarios of polypropylene Hakaiden filler

1. Kitchen waste biogas project (such as clean source treatment plant)

2. Anaerobic digestion and biogas desulfurization in sewage treatment plants

3. Agricultural biogas and landfill gas purification
