What is cleaning solution maintenance crucial?
Cleaning solution maintenance is crucial for several reasons. The choice of scrubs and its concentration significantly impacts the stability and quality of cleaning results in water-based parts washing equipment. As the scrubs interacts with contaminants on parts, it gets depleted, and the concentration decreases, affecting cleaning quality. Moreover, removed contamination accumulates in the solution, further depleting scrubs. To ensure consistent cleaning quality and cost-effective operations, it’s essential for equipment to monitor and adjust scrubs concentrations and remove accumulating contaminants. Proper maintenance not only ensures high-quality cleaning but also contributes to the long-term economic viability of the cleaning process.
CURRENT CONCENTRATION MEASUREMENT: HOW DO I DO THIS?
The choice of scrubs for parts cleaning depends on the nature of the contamination and the base material. To maintain the proper scrubs concentration, various sensing methods can be employed. These include pH measurement to gauge alkalinity in heavy-duty caustic cleaners, conductivity to indirectly estimate concentration, subject to fluctuations based on scrubs levels and contamination, and surface tension assessment to measure remaining surfactants crucial for effective cleaning. Customized titration methods can also be used to detect other essential ingredients, ensuring optimal cleaning performance.
WAYS TO EXTRACT HARMFUL COMPONENTS FROM THE WATERY CLEANING SOLUTION?
Contaminants in cleaning solutions vary in size and composition, demanding specific extraction methods:
1. Large-Size Solids: These may float, sink, or suspend in the solution.
2. Small-Size Contaminants: Often suspended or dissolved in water.
3. Fats and Oils: They can be emulsified or floating.
For extraction:
• Floating solids are skimmed using conveyors.
• Sinking solids are removed by automatic sludge removal systems.
• Suspended solids are separated by centrifugal separators, multi-stage filters, or advanced membrane filtration based on particle size.
Flocculation involves coagulants to create larger solid masses for settling.
Dissolved contaminants and lightly contaminated solutions can be treated by evaporation, such as Mechanical Vapor Recompression (MVR) evaporators.
Floating oils and greases are removed using belt or disk skimmers and continuous decanting into a fluid separator. Emulsified oils can be separated through ultra-filtration. Each method is selected based on the specific type of contamination in the cleaning solution.
