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)

WATER 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.

6
WASTE 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.

7
CONVENTIONAL 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.

8
PROBLEM 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.

9
OUR 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

10
WORKING 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.

11
METHODOLOGY
  • 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.

SAMPLES FROM
  • Tidal Park
  • Nokia Plant

TESTS 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..,

17
TYPES OF TEST
  • Viscosity Test
  • Filterability Test
  • Biological Test .etc,

18
VISCOSITY 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.

19
FILTERABILITY TEST
  • It is performed by using Filter Paper.
  • Its mesh is similar to the membrane

20
BIOLOGICAL TEST
  • It is used to find out what type of germs
    bacterias available in the Sludge.

21
SCOPE 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.
