Plant for Technogenic Sedimentation of Low-Grade Slurries

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a facility designed to separate out valuable materials from low-value sludge (such as phosphate sludge) through a controlled sedimentation process. It utilizes specially shaped and arranged rinsing areas with V-shaped walls to direct and manage the flow of sludge, optimizing sedimentation of reusable materials and water separation under regulated rinsing conditions.

Use CasesContent extracted from patent full text and abstract with AI.

• Processing wastewater from phosphate mining or fertilizer production to recover usable minerals.
• Treating industrial sludge to separate and retrieve valuable elements before disposal.
• Improving recyclable material yield in municipal or industrial sludge management plants.
• Environmental remediation at contaminated sites with sediment or sludge containing low-value byproducts.

BenefitsContent extracted from patent full text and abstract with AI.

• Increases recovery of valuable materials from waste or low-value sludge, reducing resource loss.
• Minimizes environmental impact by allowing for better separation and management of potentially polluting materials.
• Optimizes sludge handling efficiency through controlled flow and sedimentation processes, potentially reducing operational costs.
• Facilitates further recycling or safe disposal of residual sludge, supporting circular economy efforts.

Patent Abstract

The plant for technological sedimentation of low-valuable sludge, comprises a rinsing place with a dam (D) or a slope, a rinsing surface (A) and a tailing pond (T), where a sludge stream (S) subjecting a controlled rinsing regime is channeled in flow direction. An extending limiting wall pretends the sludge flow of a flow path dependable flow width in the flow direction. The rinsing places are divided through adjacent V-shaped limiting wall and form areas in the form of opposedly, fortified, isocelses triangle. The V-shaped limiting wall has an opening angle of 30-90[deg] for the sludge stream.

An extending limiting wall pretends the sludge flow of a flow path dependable flow width in the flow direction. The rinsing places are divided through adjacent V-shaped limiting wall and form areas in the form of opposedly, fortified, isocelses triangle. The V-shaped limiting wall has an opening angle of 30-90[deg] for the sludge stream. The low-valuable sludge adjusts the sedimentation area of the concentrated recyclable material in the rinsing area diagonally to the sludge stream in the result of a controlled rinsing regime. The rinsing places are operated in controlled manner so that the sedimentation area of the individual rinsing place concentrated with the recyclable material and the sludge lies in an alignment diagonally to the flow direction of the sludge. The limiting wall comprises diffusers in the area of the sedimentation area concentrated with the recyclable material. A distribution line (V) lies on each dam side for the sludge and a rinsing tube branches off from the distribution line to each adjoining upper rinsing area. A collection line lies at each dam side for beach water and a suction tube branches off from the collection line in each tailing pond. The rinsing regime controls the initial flow rate of the sludge. The sludge consists of phosphate.
