White cloud in Biodiesel, Visible After Centrifuging

I recently made some biodiesel off of used equipment. When I made the biodiesel, there was a slight haze. I centrifuged the biodiesel to check for sediment and this film/cloud settled to the bottom while the biodiesel itself cleared up. From my experience, this doesn’t appear to be soap or anything else I could find online.

Any ideas on what it is?

Could be a very small amount of water. Monoglycerides can look hazy as well.

After centrifuging, water should’ve settled to the bottom. I tried adding water to it and centrifuging again - it separated below the film
