Ozone & AOP for STP Tertiary Treatment Over the period of time, many different types of sewage treatment plants are designed & installed. All sewage treatment plant uses primary secondary & tertiary stages in treating domestic, commercial, institutional & industrial sewage water. The core of all treatment is secondary stage where pollutants mainly human fecal are degraded by different types of bacteria & make sewage water environmentally safe. After biological secondary stage the prime role of tertiary stage is disinfection i.e. elimination of carry forward of these bacteria & filtration. For disinfection in most of the sewage treatment plants, chlorine is used in tertiary stage. In many countries & by pollution control agencies use of chlorine in STP is prohibited due to many environmental hazards. Globally ozone is used in tertiary treatment for bacterial disinfection. In fact many environmentalist, scientists & pollution control boards strongly recommend use of ozone in tertiary stage of STP.

In urban cities, where source of fresh water is limited it is necessary to reuse treated waste water. In fact in most of commercial establishments it is mandatory to use treated sewage water in flushing, gardening & cooling tower. When any sewage treated waste water is being reclaimed for non-potable use, expected quality of treated water is very high. It is expected to be free for micro-organisms, color, & odor. So in this situation where high quality of STP treated water is expected ozone technology becomes most effective & efficient.

Increased use of personal body care products, pharmaceutical drugs & many emerging pollutants the sewage water treatment becomes more & more challenging. Advance Oxidation Process [AOP] provides much broader coverage of pollutant spectrum with higher performance. AOP mainly uses ozone with specific wave length of Ultraviolet radiation to produce hydroxyl [OH-] radicals.

Chemtronics offers Laboratory Experimental & pilot plant services to establish the result & efficiency of Ozonation & AOP.
