Aqueous rinsing liquids (code 12 03 01*) are generated during industrial cleaning, rinsing, and surface preparation processes following mechanical or chemical treatment.
These liquids are used to remove residues of lubricants, abrasive particles, metal dust, and other process-related contaminants.
During use, aqueous rinsing liquids accumulate metal impurities, surfactants, and products of chemical reactions.
Changes in the original composition create potential hazards for the environment and industrial systems.
Hazardous waste management for this category requires control of physicochemical parameters and stability of the rinsing liquids.
Regulated handling of hazardous waste involves separating aqueous rinsing streams according to contamination level and origin.
Special attention is required for storage of hazardous waste, as the liquid form increases the risk of leaks and secondary contamination.
Key storage requirements include:
- use of sealed tanks;
- prevention of evaporation and overflow;
- monitoring of liquid level and composition.
Transportation of hazardous waste is an important stage and is carried out considering corrosive activity and chemical composition.
During transportation, the following measures are ensured:
- resistance of containers to mechanical impacts;
- tightness of connections;
- availability of accompanying documentation.
Recycling of hazardous waste in the form of aqueous rinsing liquids focuses on reducing contaminant concentrations.
Technological methods help optimize the volume of such liquids within production cycles.
Environmental services for enterprises play an important role by analyzing rinse water composition and monitoring waste flows.
A systematic approach ensures compliance with environmental requirements.
Regular monitoring reduces the risk of negative environmental impact.
