plastic bubble cap tray
Plastic Bubble Cap For Chemical Industry
Bubble cap tray is a flat perforated plate with risers (like pipes) around the perforations, and caps in the form of inverted cups over the risers.The caps are usually equipped with slots or holes through which vapor comes out. The cap is mounted so that there is a space between riser and cap to allow the passage of vapor. Vapor rises through the riser and is directed downward by the cap passing through slots in the cap, and finally bubbling through the liquid on the tray. As vapor has to pass through many passages this lead to higher pressure drop and lower capacity than other conventional trays. Liquid and froth are filled on the tray to a depth at least equal to the weir height or riser height, giving the bubble-cap tray a unique ability to be used for reaction applications.

bio ball filter
Plastic Bio Ball Packing for Water Treatment
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    
MBBR packing for water treatment
Plastic MBBR for Water Treatment
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
