ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to improved means for disposal of digested sewage organic wastes by means of de-watering and safe conditioning said organic wastes.
SUMMARY OF THE INVENTION
The safe conditioning process defined herein increases the number of disposal locations where it would be permissible to dump incinerated and dewatered sewage sludge end product.
Further objectives of this invention are:
To reduce composite cost of sludge disposal resulting from said integrated operations,
Minimize volume of the disposal material,
Speed up processing time,
Improve the measure of control which can be achieved during the processing period.
Uniformity of processed material,
Eliminate formation of objectionable odors during the sludge processing operation as well as after its deposition in land reclamation projects, the sludge safe conditioning process eliminating runoff of undesirable constituents into rivers and waterways in general.
