Novel Caustic Purification
Learn about our novel caustic purification process available with Malvi-Tech.
Malvi-Tech process is capable of producing high quality caustic from impure caustic contaminated with unwanted anions such as chloride, sulfate, nitrate, azide, etc. Malvi-Tech can tailor the feasibility study for a specific case to assess processes’ cost savings potential to recycle caustic back to the process against the option of disposing it off as a hazardous waste. The option of neutralizing the caustic to render it non-hazardous before disposal may be the best option in some cases. Malvi-Tech offers a non-traditional process to do that without introducing alien ions into the mix and without impacting waste’s volume or amount.
In some cases the sodium compound contaminating the caustic, for example sodium azide, may have a value, requiring its separation and recovery from caustic instead of losing it to waste caustic. Malvi-Tech offers a unique process to separate and recover sodium azide from caustic while simultaneously producing high quality caustic cost effectively. The process is suitable for several other situations similiar to the sodium azide contamination in caustic solution.
