The NOx purification capability of the NOx storage decomposition catalyst (20) is restored thereby.

Nova Devimar is equipped with the latest facilities with purification systems and machinery, with a capacity of 80,000 kg per day.

While attaining a satisfactory PM combustion efficiency, it is intended to enhance the capability of CO and HC oxidation purification.

Soil has a remarkable ability to absorb and filter contaminants.

The clearance of a molecule in medicine defines the treatment capacity of the molecule by an organ.

The whole body clearance ratio expresses how well the patient responds to a potential cleaning capacity of a dialyzer, which is used to perform the treatment.

In order to improve the cleaning efficiency, it is proposed according to the invention that the clarifying basin (9) be arranged between the lamellar separator (8) and the first compartment (C1).

The smoke alarm unit (18) is housed within a module (16) that fits within the frame of the air cleaner (12) with minimal impact on the cleaning ability of the cleaner.

A blood purifying apparatus having an excellent purification performance (elimination of low-molecular weight proteins, etc.) and being contaminated with little endotoxins flowing from the dialyzate side.

An air purifier having a high air purification powers especially an air purifier which can efficiently remove floating dust, cigarette smoke, a harmful gas, etc. in the air.
