What is the best way to dispose of used OPTISHIELD and water mixture after draining a chiller?
It is the end users responsibility to dispose of and handle in accordance with all current local, state, and federal regulations. At this time OPTISHIELD is categorized as non hazardous with respect to Land Disposal Restrictions (LDR). As long as the solution has not become contaminated by outside processes, it may be disposed of as either domestic sewage, per EPA publication 40 CFR part 261.4 or industrial wastewater discharges per section 402 of the Clean Water Act, as amended.
