Fecal protozoa from inadequate sewer infrastructures, break through filtration layers.

Higher infectious risk pathogenic microorganism infection.

> Tap water must be boiled for drinking, or drinking water can be obtained separately as bottled water.

> Protozoa has chlorine resistance.

Protozoa removal requires strict turbidity control.

> Manned operation.

> Skilled operators.

Secures stable filtrate quality, even raw though water quality fluctuates.

Removes pathogenic microorganisms, no membrane deterioration & membrane breakages.

> Higher reliability.

Only periodic chemical refill.

> Unattended operation.

> Less skilled worker.
