Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aquaponic systems face challenges in efficiently managing suspended solids, leading to nutrient diffusion limitations and increased costs due to the need for additional filtration components, particularly in mineralized coupled systems where fine particles accumulate on plant roots.
Innovation Solution
A decoupled aquaponic system configuration utilizing a floating bead bioclarifier with a pneumatic backwashing mechanism to capture and transfer solids to an external mineralization basin, where aerobic digestion occurs, producing nutrient-rich water free of suspended solids without additional filtration components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a secondary filter is added between the tank and plant holding systems to offset suspended solids discharge, then root fouling is reduced, but capital and labor costs increase
Solution Approach 1:
The patent extracts and removes suspended solids from the water stream through a settling basin before the water reaches the plant holding systems. By taking out the harmful suspended solids at an early stage, the system prevents root fouling without requiring additional filtration components downstream, thus resolving the contradiction between preventing root fouling and avoiding increased device complexity
Solution Approach 2:
The patent implements preliminary action by using a settling basin to remove suspended solids before they can reach and foul the plant roots. This preliminary removal of harmful particles prevents the need for secondary filtration systems, addressing the contradiction by preventing the problem before it occurs rather than treating it downstream
2Quantity of substance
If suspended solids are discharged into the plant system from the mineralization basin, then nitrogen availability is increased, but nutrient diffusion is limited due to accumulation on plant root fibers
Solution Approach 1:
The patent segments the system into distinct functional zones: a mineralization basin for nitrogen production, a settling basin for solids removal, and a plant holding system for nutrient uptake. By segmenting these functions spatially, the system allows nitrogen to be produced and made available while physically separating the suspended solids that would otherwise accumulate on plant roots and limit nutrient diffusion, thus resolving the contradiction between nitrogen availability and nutrient diffusion
3Quantity of substance
If a settling basin is used to remove suspended particles, then water clarity is improved, but fine particles greater than 100 microns are not effectively removed
Solution Approach 1:
The patent changes the operational parameters of the settling basin by adjusting flow rates, residence times, and particle size thresholds to optimize removal efficiency. By modifying these parameters, the system achieves effective removal of fine particles while maintaining adequate water clarity, resolving the contradiction between particle removal quantity and removal precision

AI summary
An aquaculture system including a fish tank, a floating media bioclarifier, and a mineralization tank. The mineralization tank includes a first influent inlet for receiving sludge having a first solids concentration from the bioclarifier, an effluent outlet for returning to the bioclarifier a fluid having a second solids concentration less than the first solids concentration, and a second influent inlet configured to receive influent from the fish tank which has bypassed the bioclarifier. A hydroponic system is configured to receive effluent from the bioclarifier.
