All kinds of waste, urban sewage and industrial waste water needs to be filtered and separated prior to discharge to the environment, porous ceramic acts as the "environmental Messenger" role. Waste gas and waste liquid often contains toxic and harmful substances, such as vehicle exhaust and factory smoke, heavy metals in semiconductor industry waste water pollution above, if not addressed, will result in serious consequences such as acid rain, water pollution, soil pollution. Using porous ceramics, waste gas or waste water through the porous ceramic bodies, in which particles of harmful substances are adsorbed onto porous structure, purification of gas or liquid can be discharged into the environment.
