Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wastewater treatment methods for drilling operations are costly and inefficient in removing sediments from water, leading to increased operational expenses due to stringent environmental regulations.
Innovation Solution
A method and system that uses agglomerating additives to promote sediment agglomeration in contaminated water from drilling rigs, followed by separation using a centrifugal separator, producing treated water with reduced sediment content for reuse in drilling operations, while managing turbidity and pH levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional wastewater treatment methods are used, then environmental regulations are met, but operational costs increase significantly
Solution Approach 1:
The invention changes the physical-chemical parameters of water by injecting steam to heat and evaporate contaminated water, transforming it into fresh water vapor that condenses into purified water, thereby reducing operational costs while meeting environmental compliance requirements
Solution Approach 2:
The invention utilizes phase transitions of water (liquid to vapor to liquid) through steam injection and condensation to separate contaminated water from sediments, achieving cost-effective treatment that meets environmental standards
2Object-generated harmful factors
If conventional wastewater treatment methods are used, then sediments are removed, but treatment efficiency is low
Solution Approach 1:
The invention uses phase transition of water through evaporation and condensation to efficiently separate sediments from contaminated water, achieving high treatment efficiency and effective sediment removal
Solution Approach 2:
The invention replaces mechanical sediment removal systems with a thermal-based phase transition process, simplifying the treatment mechanism while improving productivity and treatment efficiency
3Ease of operation
If contaminated water is released back into nature, then operational simplicity is maintained, but environmental damage occurs
Solution Approach 1:
The invention changes the parameters of contaminated water through steam heating and condensation, transforming it into fresh water that can be safely released or reused, maintaining operational simplicity while preventing environmental damage
Solution Approach 2:
The system uses steam from the drilling operation itself to treat the contaminated water, making the treatment process self-sufficient and maintaining operational simplicity without requiring external treatment facilities
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
The system effectively recycles contaminated water by reducing total suspended solids by at least 100 times, meeting environmental standards and operational requirements, allowing for continuous or batch treatment processes, and maintaining optimal turbidity and pH levels.
Implementation Method 1
dispensing agglomerating additives in the inlet tank and mixing the agglomerating additives in the contaminated water contained therein, the agglomerating additives promoting agglomeration of the sediments into larger particles
Implementation Method 2
separating at least a portion of the sediments from the tapped portion to produce treated water and a sludge including the at least a portion of the sediments
