movable sewer treatment plant

1. PROPOSAL OF PRE
SELECTION MOVABLE
SEWER TREATMENT
SYSTEM FOR MILITARY
ESTABLISHMENTS

2. Introduction
 Every year water and sanitation problems cause more deaths than
war and the lack of sanitation is the world’s biggest cause of
diseases.
 48% of the world’s population does not have access to adequate
sewage treatment.
 Therefore need to proper treatment system in every sector.
 A treatment plant’s primary objectives are to clean the sewage
and meet the plant’s discharge standards.
 The treatment plant personnel do this by reducing the
concentrations of solids, organic matter, nutrients, pathogens and
other pollutants in sewage.

3. Objectives
1
• Identify the problem
• Sewer treatment technologies
2
• Design aspects for the sewerage
treatment
3
• Design of sewerage treatment for mobile
application

4. Identify the problem
 Consider in military establishments, most of establishments are
not a permanent cantonments.
 Military person are involve in sudden disasters in the country (ex:
war, flooding, landslides, pandemic situations).
 Nearly 300 to 500 heads basically movement in cases of the
military establishment.
 At that case nearly 49000L to 8200L sewerage discharge per day.
 Also need to minimum 20 days sewerage disposal and treatment
process.

5. Identify the problem
 Normally military people effluent BOD nearly 300mg/L.
 Before discharge the effluent need to design movable sewerage
treatment plant for reduce BOD level up to 25mg/L.
 Other thing is the latest disaster in the world is Covid pandemic
situation.

6. Sewer treatment technologies
 Physical treatment
 Screens
 Grit chamber
 Clarifiers

7.  Biological treatment
 Trickling filter
 Activated sludge
 Rotating biological contractors
 Pond system
 Chemical treatment
 Chemical reaction

8. Sewer treatment process

9. Literature Survey

10. Research gaps
1. Most of the cases using MBR system
 Impacts on their cost, relative to their design & operation
 Membrane surface fauling,clogging
 Member surface cleaning
 Member aeration
2. Treated effluent is not meeting biochemical oxygen demand (bod)
targets
 Incomplete wastewater treatment due to organic overloading
 Low oxygen concentration
 High algae or sulphur bacteria growth
 Low hydraulic detention time

11. 1. Downstream equipment is failing due to a build of large solids, hairs and fibres
 Downstream plant and equipment from any possible damage
 Accumulation of unwanted material that will interfere with the wastewater
treatment process
1. Treated effluent is not meeting total nitrogen (TN) target
2. A direct consequence of odour issues associated with the sewerage treatment
plant

12. Proposal
1. Primary treatment/screening
 Mechanical pre-treatment on top of the container
 Install compact units for grease separation and sand remova
 Tanks collect the removed waste constituents for separate disposal
 Primary treatment can be built into the system by use of settling in a
pre-treatment tank
1. Biological treatment
 process can incorporate an SBR type system
 The type of biological treatment depends on the wastewater type and
concentration
 biological treatment process and all necessary controls are fully built into the
container

13. 1. Clarification
 effluent is use separators built into containers providing high flow capacity
final clarification prior to discharge.
1. Tertiary treatment
 where stringent discharge limits exist and require the integration of tertiary treatment
modules into the treatment process such as chemical dosing, phosphorous reduction and
disinfection
