COMPARISON of

STP (Bacteria-based)

VS.

NBIRO (Non-Bio)

• PARAMETER-1: NO FOUL ODOR ?

NBIRO STP

****** ***

YES Patented foul odor;

normally placed away

From residential area

• PARAMETER-2: NO AERATION TANK?

NBIRO STP

***** ***

YES Aeration tank,

a standard

equipment

• PARAMETER-3: NO BACTERIA, NO

ENZYMES?

NBIRO STP

***** ***

YES Germs-dependent

Via organic

Purification

• PARAMETER-4: NO TOXIC GASES?

NBIRO STP

***** ***

YES Hydrogen sulfide,

methane, & ammonia

are toxic gases and are constantly

emitted from the

Aeration tank by

huge blowers

• PARAMETER-5: RAPID REACTION IN

MINUTES?

NBIRO STP

***** ***

YES Slow process in days

• PARAMETER-6: NO SLUDGE REQUIRED?

NBIRO STP

***** ***

YES Sludge-dependent

as it cultures Bacteria

• PARAMETER-7: INDEPENDENT OF

TEMPERATURE?

NBIRO STP

***** ***

YES @>37˚C population

is reduced; all dead @ 4o˚C;

Thus needs re-starting;

A problem during summer

• PARAMETER-8: UN-AFFECTED BY OIL

& GREASE?

NBIRO STP

***** ***

YES Oils adhere to bacterial

Floss reducing oxygen

Transfer; @ 20˚C =>

toxic effect

• PARAMETER-9: UN-AFFECTED BY

FOAMING?

NBIRO STP

***** ***

YES Foaming results to

Sludge loss; thus

Poor settling

• PARAMETER-10: UN-AFFECTED BY

ALCOHOL, CHLORINE, AND OTHER DISINFECTANTS?

NBIRO STP

***** ***

YES These kill the bacteria;

Halts the bio-process;

Leads to re-starting

• PARAMETER-11: UN-AFFECTED BY

TOXIC SUBSTANCES: AROMATICS,

HALOGENATED HYDROCARBONS,

METAL SALTS

NBIRO STP

***** ***

YES These stops the

bio-process; leads to

Troublesome re-starting

• PARAMETER-12: UN-AFFECTED BY BAD

INFFLUENT DISSOLVED

OXYGEN (D.O.)?

NBIRO STP

***** ***

YES @<1 ppm D.O.=> Loss of

Sludge; de-nitrification

And high D.O. Causes

Sludge to float

• PARAMETER-13: UN-AFFECTED BY HIGH

CHLORIDES?

NBIRO STP

***** ***

YES @>200 ppm chlorides

would adversely affect

the bio-process

• PARAMETER-14: UN-AFFECTED BY BAD

INFFLUENT pH?

NORMAL RANGE = 6.5-8.5

NBIRO STP

***** ***

YES Bad pH de-activates the

sludge process; acidic

pH produces filamentous

bacteria w/c causes

sludge bulking

• PARAMETER-15: ECONOMIZES ON

WATER?

NBIRO STP

***** ***

YES Not good to re-cycle

due to due to bacteria in

recycling the effluent

• PARAMETER-16: SMALL SPACE

REQUIRED?

NBIRO STP

***** ***

YES Patented huge space

due to the need tocalculate the

retention time in the

Aeration tank;

Vol / Flowrate

• PARAMETER-17: ECONOMICAL UNIT

PRICE?

NBIRO STP

***** ***

YES EXPENSIVE

• PARAMETER-18: ECONOMICAL

OPERATIONS &

MAINTENANCE (O & M)

COSTS?

NBIRO STP

***** ***

YES Very high O/M cost

• PARAMETER-19: EASY TO OPERATE?

NBIRO STP

***** ***

YES Complicated: too

Due to many process

Automatic variables

Controls

• PARAMETER-20: PROVEN TO HAVE

PASSED ALL THE DENR

& INTERNATIONAL

EFFLUENT STANDARDS?

NON-BIO STP

******* ***

YES Not all

• PARAMETER-21: CONSISTENT RESULTS ?

NBIRO STP

***** ***

YES NO

•SOCIAL POSITIONS:

ENVIRONMENT:

CLEAN & HEALTHY

• STP A “NO-NO FOR HOSPITALS :

BECAUSE OF :

1. Foul odor

2. Emission of toxic gases: hydrogen

Sulfide, methane, ammonia, etc.

3. Hospitals are symbols of health

4. Alcohol in the inffluent water.

Germs won’t grow. STP won’t work.

5. Economics of hidden costs: process not working yet pumps & blowers are operating. Owners don’t know.

NBIRO

Definitely, the better system as

compared to STP

Non-Biological and Reverse Osmosis Waste Water Treatment System
