Solution Overview

Problem

Vinasse, a residue from sugar-alcohol and ethanol production, poses significant environmental pollution risks due to its high organic matter and nutrient content, with existing treatment methods being inefficient and costly, and direct infiltration into soil leading to eutrophication and contamination.

Innovation Solution

A high-performance flotation process is developed to treat vinasse within existing storage tanks, utilizing coagulation, flocculation, aeration, and nano/micro air bubbles to remove pollutants, resulting in concentrated sludge and treated vinasse that can be reused as fertilizer, reducing transportation costs and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If vinasse is disposed directly into the environment, then the volume of vinasse is quickly reduced, but high polluting potential and eutrophication of natural waters occur

Engineering Contradiction:
Improvedisposal speedVSAvoidpollution and eutrophication
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary treatment process using flotation technology with coagulants and flocculants between the vinasse and the environment. These chemical intermediaries aggregate suspended solids and contaminants into removable flocs, allowing rapid disposal while preventing direct pollution of water bodies and soil.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The flotation process extracts and removes contaminants, suspended solids, and pollutants from vinasse by forming separable flocs that can be physically removed. This extraction separates the harmful components from the treated effluent, enabling safe disposal while maintaining speed.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of energy

If vinasse is infiltrated directly into soil for fertirrigation, then transportation and disposal costs are reduced, but contamination of water table and degradation of soil properties occur

Engineering Contradiction:
Improvedisposal costVSAvoidwater table contamination and soil degradation
Core Design Contradiction:
Loss of energyVSObject-affected harmful factors

Solution Approach 1:

The flotation treatment acts as an intermediary processing step between vinasse generation and soil application. By treating vinasse before disposal, the process enables safe fertirrigation with controlled nutrient content, preventing water table contamination and soil degradation while maintaining cost-effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The treatment process changes the physical-chemical parameters of vinasse by removing excess organic matter, suspended solids, and contaminants through flotation. This parameter modification produces a treated effluent suitable for safe soil application, enabling cost-effective disposal without environmental harm.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If conventional treatment methods are used, then some treatment effect is achieved, but high costs and inefficiency persist

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent replaces conventional mechanical treatment systems with flotation technology that uses air bubbles and chemical aggregation. This substitution achieves superior treatment effectiveness for vinasse with lower operational costs and simpler equipment requirements compared to traditional methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The flotation process changes the operational parameters of treatment by using gas-liquid-solid three-phase separation instead of conventional liquid-liquid or solid-liquid separation. This parameter change enables more efficient contaminant removal at lower costs with simpler process control.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If flotation process is applied to treat vinasse, then pollution removal efficiency is significantly improved, but complex equipment and process control are required

Engineering Contradiction:
Improvepollution removal efficiencyVSAvoidequipment and process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flotation process is segmented into distinct functional stages: coagulation, flocculation, flotation, and sludge removal. Each stage uses simple, dedicated equipment performing a single function, which reduces overall system complexity while maintaining high pollution removal efficiency through optimized step-by-step treatment.

Inventive Principle:
Principle #1Segmentation
