<x-charset ISO-8859-1>Franklin, Magnesium sulfate (Epsom Salt) added to your waste wash water will alter the suspended soaps from dissolvable sodium or potassium to insolvent magnesium soaps. These will rise to the water's surface in the form of a greasy solid that can captured and used in a lubricating capacity or burned as a solid fuel.. Aluminum sulfate might also work.
This will mean the chemical substitution of the sodium or potassium "x-oate" with sodium or potassium sulfate, which brings up two points. One, better to use potassium hydroxide as the catalyst as their is greater use for potassium waste products as fertilizing agents than for sodium. Two, the use of the acid/base process reduces total chemical inputs, which in turn reduces waste stream volume, both water and chemicals.

As much as possible I maximized the used of water for washing. I asked my chemist friend if there is a way of removing soap residue in my soap water after washing BD but he gave me more problem than solution such as enzyme, bacteria and others. Any suggestion from our group members of how to treat soap or remove soap before pouring my washing water into city sewer line My initial remedy is I dug a pit deep enough to accomdate my wash water for natural seepage but when rainy day come the pit will be pull of rain water and soap mixed. It a remedial solution and better have permanent remedies to eliminate water pollution.

I will use the bubble washing process. I have made what I think is 3 one litre batches of biodiesel. 2 from new oil and 1 from used oil. All 3 have seperated very clearly. I am going to try to wash the 3 and see what happens. Thanks Rick M Brownstown, Mi I reckon most washing problems are really processing problems in drag. Standard bubblewashing is recommended Rick.
