35 results about "Septage" patented technology

Landfills and their methods of operation are disclosed. Through the controlled introduction of septage into solid municipal waste, refuse decomposes faster to achieve additional landfill space. A business method of operating the landfill is also disclosed.

A batch process for the treatment of an aqueous solution so that the treated product is more desirable for disposal includes obtaining an influent batch of aqueous solution for treatment, treating the batch of solution by an advanced oxidation process. The advanced oxidation process including causing ozone to be mixed with the solution, maintaining the mixture of solution and ozone at a pressure above atmospheric for a time of at least two seconds. In a preferred embodiment of the process, the process includes continuously recirculating the fluid to be treated, through a recirculation conduit, the recirculation conduit including an ozone injector and the ozone injector is adapted to inject ozone into the aqueous solution as the aqueous solution circulates through an ozone injector. Influent to be treated may be selected from the group including sewage, septage, leachate, ballast or other aqueous solutions where it is desirable to treat the fluid prior to disposal, further treatment, or reuse. The process is carried out to improve a level of disinfection and / or denutrification of the effluent.

Treatment of an aqueous solution to yield a product is more desirable for disposal by an advanced oxidation process. Ozone is mixed with the solution, and maintaining at an elevated pressure for a time. The process may include recirculation past injector that injects ozone into the solution. Influent may be sewage, septage, leachate, ballast, and so on. The process disinfects and / or denutrifies the effluent. It may include (a) back-to-back processing of batches (b) overlapping processing with a previously treated batch (c) off-gassing (d) repetitive high pressure and low pressure cycles (e) post processing steps, such as retention without addition of ozone for a period of time to permit flocculates longer to form (f) post process filtering to remove flocculates (g) simultaneous post-processing of one batch while another batch is being processed. The process may include the treatment of solutions containing pharmaceuticals.

The invention relates to a process for concentrating and dehydrating ultra-fine tailings, which is characterized in that the process comprises the following steps: 1) stirring the tailings slurry to make it into a suspended slurry; Slag separation to remove sundries; 3) Preparation of flocculant, adding to the slurry after separation of slag and stirring twice; 4) Mixing of flocculant and pulp, using a high-efficiency thickener to concentrate the pulp; 5) Concentration underflow It is sent to the filter press for pressure filtration, and the overflow is clarified and used as industrial circulating water. This solution greatly reduces the moisture content of the tailings, the filter cake is loose and does not need to be broken up, the forklift shovel does not stick to the bucket, the car transport unloads the material without sticking to the box, and there is no dripping during transportation. The quality requirements of the calibrator improve the utilization rate of tailings resources.
