My presentation on treating polluted pond water using orange peel as an adsorbent.

2. OBJECTIVE OF STUDY
 To examine the COD reduction in a selected polluted river
wastewater by using natural adsorbents, to minimize the
treatment cost.
To removes the TSS present in the waste water.
To check that it removes the color of trail sample.

3. LITERATURE REVIEW
In our laboratory the work is in progress to demonstrate the
management of solid textile mill sludge (STMS) by
vermicomposting.
Aline Sartório Raymundo, Romina Zanarotto, Marciela Belisário,
Madson de GodoiPereira, Joselito Nardy Ribeiro and Araceli
Verónica Flores Nardy Ribeiro (2010) A methodology involving
sugar cane bagasse bio-adsorbent was developed in order to
remove the carcinogenic congo red dye from aqueous medium.
Teh Ubaidah Bt Noh (2010) Natural materials have been
investigated as potential industrial adsorption media.

4. MATERIAL USED
MATERIAL DEPTH SIZE USES
Coarse Aggregate 20 cm 20mm Filter for waste
water
Fine aggregate 20 cm 4.75mm Filter for waste
water
Carbon 20 cm 2.75mm
Remove dust
Orange peel 20 cm 0.75mm Remove the color

7. SAMPLE COLLECTED
• The sample was collected from the Chandra river
located at Karaikal district in Puducherry.
• The river was located near the Soap factory.
Hence the chemical may contaminated into the river
and polluted.

8. EXPRIMENTS
pH Test,
BOD Test,
COD Test,
TURBIDITY Test,
TOTAL SUSPENDED SOLIDS.

9. RESULT
PARAMETER INFLUENT EFFLUENT STANDARD
ODOUR Muddy smell None None
COLOUR Bluish green 90% remove Colorless
pH 8.67 7.9 8.5
TSS 2900 mg/l 495mg/l 500 - 5000
COD 1640 mg/l 265 mg/l 250 – 500 mg/l
CONDUCTIVITY 10.9 milli-mho 2.3 milli-mho 5 milli-mho
TURBIDITY 32.3 NTU 12.86 NTU 10 NTU

10. MERITS
 Eco-friendly.
 Materials are easily available.
 It removes acidic dyes from industrial effluent.
 It’s a effective method for removing harmful wastes.
 Activated carbon obtained from orange peel via acid
decomposition has been found to be an efficient
material for dye removal.
 Low cost material for removing dyes effluent.

11. demerits
 We can’t implement it for large scale.
 It takes much time to absorb the dyes.
 Maximum removal is up to 87% of wastes.
 Adsorption increases with increase in pH.

12. conclusion
90% of colour has been removed from the water sample.
80% of COD and TS has been removed from the water
sample.
So it is not suitable for drinking purpose but it will
used to unobjectionable industrial uses such as
cooling and non- potable domestically uses .
