I'm looking for recommendations on effective deemulsifiers suitable for several specific separation processes. First, I need solutions for separating refined animal fat from water. Additionally, I'm interested in deemulsifiers that can aid in separating refined animal fat combined with fatty acid methyl ester from methanol, particularly under acidic pH conditions. Furthermore, I require products that can effectively separate fatty acid methyl ester from glycerol and methanol in a basic pH environment. It's crucial that the proposed deemulsifiers are non-toxic and environmentally friendly, ensuring they pose no harm to aquatic life or the ecosystem. If you have suitable options, please provide the relevant details, including any technical specifications and application guidance. Thank you!
