Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment devices face difficulties in accurately measuring and efficiently extracting sludge from under lamellar settling cells due to limited access, leading to inefficient sludge removal and cleaning operations.
Innovation Solution
A separator-decanter device with a means of access that traverses the lamellar settling cell, allowing direct measurement of the sludge veil and efficient removal through a sensor and suction pipe, minimizing interference with the settling surface and maintaining laminar flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a lamellar settling cell is used for water treatment, then particle separation and settling efficiency is improved, but access to the storage zone under the cell for measurement and sludge extraction becomes difficult or impossible
Solution Approach 1:
The invention introduces a separate access means (duct or opening) that provides independent access to the storage zone under the lamellar settling cell. This segmentation allows measurement and sludge extraction operations to be performed without interfering with the settling process, resolving the contradiction between maintaining settling efficiency and enabling access for operations.
Solution Approach 2:
The access means acts as an intermediary element that bridges the gap between the external measurement/extraction equipment and the storage zone under the settling cell. This intermediary structure enables precise sludge level measurement and efficient sludge removal while preserving the integrity and functionality of the lamellar settling cell.
2Productivity
If the lower section of effluent channels is closed to maintain laminar flow, then settling efficiency is improved, but access under the settling cell for sludge extraction becomes impossible
Solution Approach 1:
The invention separates the flow maintenance function from the access function by providing a dedicated access means independent of the effluent channels. This allows the channels to remain closed for optimal settling while the access means provides separate entry points for sludge extraction operations.
Solution Approach 2:
The access means is positioned at the lower section of the settling cell, providing access from a different spatial location than the effluent channels. This dimensional approach allows simultaneous maintenance of laminar flow in the channels and provision of access for sludge extraction.
3Ease of operation
If sludge measurement is carried out in an upstream compartment, then access is easier, but the measurement is not representative of actual sludge storage in the settling compartment
Solution Approach 1:
The access means serves as an intermediary that enables direct measurement in the storage zone while maintaining ease of operation. By providing a dedicated access path to the actual sludge storage location, the invention allows external measurement equipment to accurately assess sludge levels without requiring access to upstream compartments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise sludge level measurement and effective sludge extraction, improving the reliability and efficiency of sludge removal and cleaning operations while maintaining the separation and settling process.
Implementation Method 1
The lamellar cell makes it possible to create and maintain a laminar flow making it possible to ensure the separation and settling of the solid particles contained in the treated liquid
Implementation Method 2
These particles then fall into a sediment retention cell, positioned under the lamellar cell, where they will agglomerate to form sludge
