System Design Approaches

The problems described above can be eliminated by adhering to sound engineering practices when the system is designed and applying prudent management principles in the operation of the equipment. 

One effective design approach is depicted in figure attached herewith. This system contains the purification components and includes recirculation pump. The pump provides for recirculation of water within the system whenever a low flow or no flow situation exists. This serves not only to reduce bacterial proliferation, but also maintains system purity. The design also incorporates ultraviolet sterilizers and media trap filters. The sterilizers destroy bacteria in the purified water stream. The filters remove particles from the water stream, which could shield bacteria from the ultraviolet radiation, maximising the efficiency of the sterlizers.

Some of the salient features of Storage and Distribution, Instrumentation and Sanitization are highlighted below, enabling to achieve the objective with proper optimisation.
