The counts of bacteria, total coliforms and fungi of pure water in the water dispensers were detected and the regular pattern of bacterial reproduction in water were studied after the dispensers and water were disinfected.

A case study of water dispensers is reported to explain a systematic methodology based on dynamics programming(DP),which is proposed to plan the launch timing of new modules that will replace the existing modules of an evolving product family(PF) architecture.

Objective To observe the germicidal efficacy of ultraviolet rays in water dispenser.

In order to know the sanitary conditions of the bucket drinking water and the parts of drinking water machine during use by the users, the food sanitary microbiological examination method was used for selective examination.

Exploitation of new product for drinking water dispensers based on inverse engineering technology;

Design of Injection Mould for Tap of Potable Water Machine;
