2STUDY OF DEWATERING OF MBRS WASTE ACTIVATED
SLUDGE (WAS)
AIM
3 AQUA DESIGNS INDIA LIMITED
COMPANY PROFILE
- Aqua Designs is the only Water Treatment Company
in India to have ISO 90012000 Certification for
all the activities which includes Design,
Engineering, Manufacturing, Project Execution,
Laboratory Services, Water Treatment Chemicals
and Operation Maintenance Services. - Aqua Designs supply water and wastewater
treatment equipment to fit the needs of
Industries and Domestic applications. - They are also Doing Operation and Maintenance
(OM)

5WATER TREATMENT PLANT
- The Process of Converting Waste Water into
Drinkable and useful water. - Some of the wastes from,
- Power stations, Refineries, Food Beverage,
Automobile , Petro-chemical , Pharmaceuticals,
Textiles, Oil Gas, Leather Tannery , Metal
Refining, IT Parks, etc.
6WASTE ACTIVATED SLUDGE
- During the process of Dewatering the Sludge is
formed. - Sludge is nothing but Solid Waste mixed with
Waste Water. - In Normal level 8 gm/lit is allowed to MBR
Process. - If it is exceeds 15 gm/lit Sludge is called
Activated Sludge, and it is deposited in the
bottom of the aeration tank.
7CONVENTIONAL SLUDGE THICKENING
- Sludge Thickening is the Process of maximum
Removal of Water from the WAS. - Now thickening is carried out by Conventional
Sand Bed method.
8PROBLEM OF CONVENTIONAL METHOD
- It is Difficult to Thickening the Waste Activated
Sludge efficiently. - The Time taken for the Process is High.
- The Space required for Sand Bed Thickened
Sludge Storage is High.
9OUR NEW SLUDGE THICKENER
- In Order to Overcome Problems of the Conventional
Method, We are going to Develop the New Method. - It is a Mechanical type Thickener. It is Works
under the Principle of Spinning Action of the
Washing Machine
10WORKING PRINCIPLE
- We are Loading the Activated Sludge in the
Machine. - The Spinning Action takes place in the Machine.
- Now the maximum Water Removed from the WAS.
- After that the Sludge is going to Dry for removal
of moisture for easy Disposal.
11METHODOLOGY
- Collection of Samples from Various Plants.
- Test the MLSS Level in the Sample.
- Design the WAS Thickener.
- To analyse the Efficiency , Cost Energy
Consumption of the WAS Thickener.

16TESTS FOR SLUDGE
- Some of the tests are needed to find out the
behaviour of the Sludge, materials and Germs
mixed with Sludge. - Sludge properties are changed depends upon the
type of Plant (ie) Leather tanuries, Chemical
Industries, Canteen wastes etc..,
17TYPES OF TEST
- Viscosity Test
- Filterability Test
- Biological Test .etc,
18VISCOSITY TEST
- Viscosity is directly proportional to the
Concentration of the Sludge. - If the Viscosity of the Sludge is High means the
Concentration of the Sludge is High. - It will reduce the Dewatering ability.
19FILTERABILITY TEST
- It is performed by using Filter Paper.
- Its mesh is similar to the membrane
20BIOLOGICAL TEST
- It is used to find out what type of germs
bacterias available in the Sludge.
21SCOPE OF THE PROJECT
- The maximum Removal of Water in efficient method.
- To Reduce the Space required.
- Low Time Consumption.
- The Sludge Removal is Easy.
- This method is very much useful in future for all
the Water Treatment Plant.
