🔴 Waste water engineering

♦️ Trickling Filter

🔸 Trickling Filter works on the principle of attached culture system.

🔸 Detachment of attached biofilm from the surface is called Sloughing

🔸 BOD removal efficiency is 75 to 80%

🔸 Types of Trickling Filter

1. Conventional or Standard rate Trickling Filter :-

👉 Depth of filter media :- 1.2 to 2.4 m

👉 Size of media :- 25 to 75 mm

👉 Land required :- More

👉 Hydraulic loading :- 22 to 44 ML/hect/day

👉 Organic loading :- 900 to 1200 kg of BOD/hect-m.

👉 Recirculation system :- Not provided.

2. High rate Trickling Filter

👉 Depth of filter media :- 1.2 to 1.8 m

👉 Size of media :- 25 to 60 mm

👉 Land required :- Less

👉 Hydraulic loading :- 110 to 330 ML/hect/day

👉 Organic loading :- 6000 to 18000 kg of BOD/hect-m.

👉 Recirculation system :- always provided for Increase loading

🔸 operational problems

👉 Psychoda problems :- fly nuisance.

👉 Odour nuisance :- The remedy is Chlorination of sewage.

👉 Ponding problems :- Filters media gets clogged due to growth of alage and fungi and this is called Ponding.

~ Adding chlorine or copper sulphate to the sewage kills alage there by Ponding can be avoided

🔴 waste water engineering

♦️ Activated sludge process (ASP)

🔸 Activated sludge :- It is sludge containing large concentration of highly active aerobic micro organisms.

🔸 ASP works on the principle of suspended culture system.

🔸 Components of ASP

A) Primary settling tank :-

~ Detention time - 1.5 to 2 hr.

B) Aeration tank :-

~ Detention time- 4 to 8 hr

C) Secondary sedimentation tank :-

~ Detention time- 1.5 to 2 hr.

D) Sludge thickener & sludge digestion tank

🔸 Activated sludge process parameters

1. Hydraulic retention time (HRT) :- It is the ratio of volume of tank to the rate of sewage flow into the tank.

2. Volumetric loading rate or BOD loading rate :- It is ratio of BOD applied to unit volume of aeration tank.

3. Food to microorganism ratio (F/M) :- It is defined as the ratio of kg of BOD applied per day to kg of MLSS in aeration tank.

4. Mean cell residence time (Sludge age) :- It is defined as mass of cell in the reactors to mass of cells wasted per day.

5. Sludge volume index :- It is the volume occupied in ml by 1 gm MLSS after settling for 30 minute from 1L sewage sample is known as sludge volume index.

🔸 Usual values adpoted

👉 F/M :- 0.4 to 0.3

👉 MCRT :- 5 to 15 days

👉 Efficiency :- 85 - 95%

👉 Recycling ratio :- 0.25 - 0.5

🔸 Operational problems associated with ASP

1. Rising of sludge :- Settled sludge contains large number of live cells. They oxidise the dead cells and release nitrogen. The nitrogen causes the sludge to risep and increases the Xe value.

~ Remedies :- Increase Qr & Decrease Q

2. Bulking of sludge :- Large number of dead cell in settled sludge and growth of filamentous organisms. Occurs when SVI ≃ 150

~ Remedies :- Bring down SVI (≃ 150), Increase pH, Increase DO, decrease F/M ratio.

🔴 Waste water engineering

Microorganisms Based on oxygen consuming

👉 Aerobic organisms :- It survives in the presence of oxygen.

👉 Anaerobic organisms :- It survives in the absence of oxygen.

👉 Facultative organisms It survives with or without oxygen.

🔴 waste water engineering

Secondary treatment (Biological treatment)

🔸 Unit based on aerobic treatment

1. Trickling filter

2. Activated sludge process

3. Oxidation pond

🔸 Unit based on anaerobic treatment

1. Septic tank

2. Imhoff tank

3. USAB Reactors

🔸 Aerobic treatment of waste water

1. Suspended culture system

👉 In suspended culture system, Biomass is an suspension in the liquid containing organic matter.

👉 E.g. Activated sludge process.

2 Attached culture system

👉 In Attached culture system, biomass is attached to medium and sewage containing organic matter is passed through medium.

👉 E.g. Trickling filter, Rotating biological contactors, Biotowers etc.
