Waste Water Treatment Plant (WWTP)

SEWAGE TREATMENT PLANT (STP)


STP Biotank

Domestic sewage treatment system sourced from bathroom, toilet, kitchen, laundry etc.

Advantages:

  1. Complete system in one tank
  2. Easy maintenance
  3. The system can be  applied by planting or on the floor
  4. Does not require much civil work
  5. Fast and easy in the agency

Biotank

This type of tank is widely used in domestic sewage treatment. Manufactured with hand lay up molding system, making it more sturdy and strong because of plus belt molding. Can be applied by planting or in open area. Capacity requirements can be tailored to customer demand.

ADVANCED OXIDATION PROCESS (AOP)

In wastewater treatment applications, AOP refers to two or more specific process combinations involving ozone (O3), strong oxidizing agents such as hydrogen peroxide (H2O2), and UV light. AOP reaction occurs based on two oxidation stages, the formation name is hydroxyl radical (OH) and hydroxyl radical reaction to the contaminant in the liquid waste feed.

Reaction formation ●OH  :

H2O2 + H2O ↔HO2– + H3O+

O3 + HO2– ↔ ●OH + O2– + O2

 

AOP HAVE POTENTIAL VALUE OF HIGH OXYIDATION

ADVANTAGES OF AOP UNITS

  • May include the maximum pollutant spectrum
  • Highly reactive in the oxidation process
  • Oxidize complex organic elements into simpler products
  • AOP design is more compatible
  • Installation and maintenance is easy
  • Zero waste
