| Maintaining a healthy environment requires the treatment of wastewater, and incorporating modern methods can have a big impact on ecosystem health and general safety. Today's integrated vacuum evaporators have shown to have significant potential for treating and managing acid waste efficiently especially coming from a high consumption chemical process in the semiconductor industry. This cutting-edge technology has demonstrated a strong potential for success in reducing the concentration of acid waste streams by almost 57%, fulfilling objectives on the cost of operation with increasing productivity, driving the need for the system to be agile as well as to adhere to the compliance with the visibility aided by automation. One of the best examples of how vacuum evaporators are being used in recovering the acids from concentrated waste streams can be evaluated from the volume generated preliminary of between average 35000 kg of acid reject and post installation of the system where it generates average of 15000 kg of acid reject. The ergonomic on the manual handling during operation which is evaluated using the NIOSH Lifting Index is reduced to zero ergo high risk because the vacuum evaporator used in the procedure automates much of the labour. Aside from the ergonomic and environmental benefits, the capacity of vacuum evaporators to renew acids and other materials makes them a profitable and commercial option which is evaluated through fieldwork studies. Apart of that, in strengthening the result brings to the survey conducted on 100 respondents where analysis covering on key areas like cost of operation, acid recovery, safety and energy efficiency determines the functionality of this technology in the market and the impact towards the industry. Both result coming from the experiment and the Likert scale analysis from the survey; not only will it align with sustainable development principles in terms of energy efficiency, but it also presents a potential cost-saving opportunity of USD 18 000 per annum for sectors that generate and handle acid waste. This could be a convincing factor to the management for the approval of future sustainable projects with high capital investment. |
