Plastic Igel Ball for Water Treatment

At present, VOCs treatment mainly uses activated carbon. Since activated carbon cannot be analyzed at high temperature, it is replaced regularly. However, activated carbon adsorbed with organic matter is a dangerous chemical with high processing cost.This environmentally friendly adsorbent material is hydrophobic molecular sieve, which is different from ordinary molecular sieve in that it preferentially adsorbs water in gas. It has a highly selective adsorption capacity for organic matter, and can be resolved at high temperature, thus realizing continuous adsorption-regeneration.The adsorption material is made into a cellular structure by a special preparation process. The adsorption capacity of organic matter is more than 2%, which can be adsorbed and regenerated for a long time. Honeycomb Molecular Sieve adopt adsorption system to reduce exhaust gas concentration and air volume, and at the same time cooperate with catalytic combustion technology to reduce operating cost.  

It was invented by Jaeger Tri. Generally speaking, No big surface area is Tri-pack's biggest advantage. The distinctive shaping of ribs, struts and drip rods gives Tri-Packs tower packing media superior wetting characteristics, and the ability to maintain uniform liquid distribution throughout the bed. In the traditional theory of mass transfer, we often think big surface area will increase the mass transfer efficiency. Sometimes, Excess surface area can impede gas/liquid contact and create higher pressure drops,. Finally, it will lead to Packing's channel blocking.Based on this new understanding, Jaeger had invented Tri-pack.  Basically this pack provides maximum surface contract between the gas and the scrubbing liquid by facilitation through continuous formation of droplets by the packed bed. It was recognized best packing in for air stripping,degasifier and scrubber    

It is a type of wastewater treatment process that was first invented by Prof.Hallvard  Degaard at University of Science and Technology in the lates of 1980s.The MBBR system consists of an aeration tank (similar to a activated sludge tank) with special plastic carriers that provide a surface where a biofilm can grow. The carriers are made of a material with a density close to the density of water (1 g/cm3). An example is high-density polyethylene (HDPE) which has a density close to 0.95 g/cm3. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the substrate in the influent wastewater and the biomass on the carriers    

Igel ball is a common biofilter material, which mainly uses polypropylene as raw material and is processed into a prickly multi needle plastic ball by injection molding process. The small cylindrical body is evenly distributed in the ball, increasing the distribution point of vapor and liquid, so that it can fully disperse vapor and liquid.
