1. Significant economic benefits
Reduce procurement costs: By recycling and distilling, effective components (such as phenidone and metol, etc.) in waste developer solutions can be recovered and reused, achieving a recovery rate of up to 95%. This significantly reduces the need for new liquid procurement, saving 30%-50% of developer costs over long-term use.
Reduce hazardous waste disposal costs: Wastewater from developing processes is classified as hazardous waste, with high treatment costs (ranging from several thousand yuan per ton). Recycling it reduces the volume of waste liquid by over 80%, directly lowering the cost of hazardous waste disposal.
II. Environmental Compliance Advantages
Reducing environmental pollution: The developer contains harmful substances such as phenols and heavy metals, which directly pollute soil and water bodies when discharged. The recycling machine separates them through distillation, concentrating the hazardous components in the residue (accounting for only 5%-10% of the original liquid volume), significantly reducing environmental load.
Simplify hazardous waste management: reduced waste liquid generation, eased pressure on storage, transportation, and declaration processes, and lowered environmental compliance risks.
3. Improvement in Process Stability
Ensure developing quality: The composition of the recovery solution is relatively stable. By mixing it with fresh solution in a proportional ratio, it maintains the consistency of parameters such as developing density and contrast, avoiding fluctuations in solution concentration caused by direct discharge of waste liquid.
Extend the lifespan of the solution: Timely recycling and treatment can slow down the oxidation and degradation of the developing solution. Some models also feature a filtration function to remove impurity particles and reduce haze.
4. Operation Safety Improvement
Reduce exposure risks: The automated recycling process minimizes manual contact with waste liquids, lowering occupational health hazards such as skin and respiratory irritation.
Improve the working environment: Enclosed recycling equipment can reduce the emission of volatile organic compounds (VOCs) and enhance the air quality in darkrooms or workshops.
For industries with high solvent usage, such as printing, imaging, and PCB manufacturing, solvent recovery machines are practical equipment that offers economic, environmental, and process advantages, typically achieving a payback period of 1-2 years.
