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..,

TYPES OF TEST

Viscosity Test Filterability Test Biological Test .etc…,

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.

FILTERABILITY TEST

It is performed by using Filter Paper. It’s mesh is similar to the membrane

BIOLOGICAL TEST

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