Abstract

The floating ball bio-filter, according to this invention, comprises at least one chamber accommodating layers of balls floating in the water to be treated, each ball having staggered slots with bacteria deposited in them, the bacteria being selected to react with, and degrade, the impurities in the water to be treated passing through such slots; the balls in each layer having predetermined densities less than the density of the water, enabling them to float at predetermined levels in the water.

Description

DESCRITPION
TITLE OF THE INVENTION
A FLOATING BALL BIO-FILTER
INVENTORS & APPLICANTS:-
(I)NARENDRA GHORPADE (2) RANGANATHAN SRINIVASAN (3) VANKIPURAM RAMAMURTHY RAMRATHNAM (4) SATISH PATEL, 225 METTUKUPPAM, OKKIAM THORAIPAKKAM, CHENNAI 600 096, TAMILNADU, INDIA, ALL INDIAN NATIONALS
(i) Technical Field to which the Invention Relates:-
This invention relates to a floating ball bio-filter, more particularly, though not exclusively, a floating ball bio-filter for use in sewage water treatment plants.
(ii) Background Art of the Invention:-
In sewage water treatment plants a stage is reached when, particularly, after clarification of the water, at the primary stage, the water is required to be further treated in the course of purification. An object of this invention is to propose a floating ball bio-filter which achieves this object. It is also an object of this invention to propose a floating ball bio-filter which is compact and efficient, so that it is space saving and highly result oriented.
(iii) Disclosure of the Invention:-
The floating ball bio-filter, according to this invention, comprises at least one chamber accommodating layers of balls floating in the water to be treated, each ball having staggered slots with bacteria deposited in them, the bacteria being selected to react with, and degrade, the impurities in the water to be treated passing through such slots; the balls in each layer having predetermined densities less than the density of the water, enabling them to float at predetermined levels in the water.
(iv) Description of Invention with reference to Drawinqs:-
This invention will now be described with reference to the accompanying drawings which illustrate, by way of example, and not by way of limitation, one of possible embodiments of the bioreactor proposed herein.
Fig. 1 illustrating a separate view of a ball
Fig. 2 illustrating three of such balls, and
Fig. 3 illustrating layers of such balls floating in the water to be treated.
A chamber C accommodates two layers L L of balls B floating in the water to be treated, each ball having slots S with bacteria deposited in them. The bacteria is selected to react with, and degrade, the impurities in the water to be treated passing (in the direction of the arrows A) through such slots.
The balls B in each layer have predetermined densities less than the density of the water, enabling them to float at predetermined levels in the water.
The water to be treated passing in the upward direction, thus gets thoroughly clarified/filtered during its upward journey through the slots in the balls by interaction with the bacteria in the slots, which degrade the impurities in the water, and also by passing through the staggered slots in the balls. The balls are preferably made of plastic. The impurities degraded and physically filtered collect at the bottom of the chamber while the bio-filtered water rises to the top and is taken away for further processing, if necessary.
It will be appreciated that various other embodiments of this invention are possible without departing from the scope and ambit of this invention.

Claims

We Claim:
1. A floating ball bio-filter comprising a chamber, accommodating layers of balls floating in the water to be treated, each ball having staggered slots with bacteria deposited in them, the bacteria being selected to react with, and degrade, the impurities in the water to be treated passing through such slots; the balls in each layer having predetermined densities less than the density of the water, enabling them to float at predetermined levels in the water.
2. A bio-filter as claimed in Claim 1, wherein the balls are made of plastic.
3. A floating ball bio-filter substantially as herein described with reference to, and as illustrated in, the accompanying drawings.
