Adsorption system
An adsorption apparatus and method of adsorption for treatment of wastewater is disclosed, and comprises an inlet for the wastewater connected to a metals trap which adsorbs metals and a second trap which filters organic materials from the wastewater, positioned between the inlet and the metals trap, wherein the second trap at least partially comprises either a phosphate or an activated carbon. The metals trap can be, for example, fish bone char. A method of manufacturing fish bone char is also disclosed.
1. An adsorption apparatus for treatment of wastewater comprising:
an inlet for wastewater connected to a pH controller;
said pH controller including a pH sensor, said pH sensor measuring a pH of said wastewater and said pH controller adjusting said pH of said wastewater to a predetermined value of from pH 5.5 to pH 7.5;
a first trap, said first trap filtering solids of a predetermined size from said wastewater;
a second trap, said second trap having a composition comprising fish bone char and said second trap filtering organics from said wastewater;
a third trap, said third trap filtering metals from said wastewater and having a composition other than said composition of said second trap; and
said wastewater passing sequentially from said inlet to said pH controller, then to said first trap, then to said second trap and then to said third trap.
2. The adsorption apparatus of claim 1 wherein said predetermined size is about 5 microns or greater.
3. The adsorption apparatus of claim 1 wherein said first trap comprises silica sand, charcoal, coal, or mixtures thereof.
4. The adsorption apparatus of claim 1 wherein said fish bone char in said second trap has a mesh size of from 4 to 400 mesh.
5. The adsorption apparatus of claim 4 wherein said fish bone char in said second trap has a mesh size of from 4 to 34 mesh.
6. The adsorption apparatus of claim 1 wherein said composition of said second trap further comprises activated carbon.
7. The adsorption apparatus of claim 1 wherein said composition of said third trap comprises a metal oxyhydroxide.
8. The adsorption apparatus of claim 7 wherein said metal oxyhydroxide comprises an iron oxyhydroxide, a magnesium oxyhydroxide, a selenium oxyhydroxide, or mixtures thereof.
9. The adsorption apparatus of claim 7 wherein said third trap further includes potassium permanganate, sodium hypochiorite, or a mixture thereof.
10. The adsorption apparatus of claim 1 wherein said second trap further includes potassium permanganate, sodium hypochlorite, or a mixture thereof.
