AI Technical Summary

Benefits of technology

In this new design for an apparatus that uses liquid coolant or other liquids instead of air during thermal cycling operations, it achieves better performance without adding extra weight or space requirements than previous designs. It also simplifies manufacturing processes while reducing its complexity. Additionally, these improvements result in improved efficiency over existing systems due to less expensive components being replaced. Overall, they improve the functionality and effectiveness of the device's function.

Problems solved by technology

This patented technical solution described in this patents solves issues related to disposing excessive amounts of industrial wastes containing harmful substances like salts or metals during manufacturing processes due to their high levels of soluble impurities (such as calcium) which may cause damage if released into waterways without being processed properly. Existing methods involve treatments involving evacuated tanks followed by settling basins, gravity separation techniques, centrifuges, thermal cycling systems, membrane distillations, ion exchange resin columns, and various combinations thereof. However, there exist drawbacks associated with current methodology including higher costs, longer startup times, larger footprint requirements, difficult maintenance, potential hazards caused from overheating, and lack of flexibility in adjustable parameters needed for effective treatment of highly concentrated solutions.
