Treated biochar for use in water treatment systems
A method and system is provided for treating water to remove contaminants using treated biochar placed in the water flow pathway of a water treatment process. The system further includes the further treatment of the treated biochar after its use in the water treatment process for use in agricultural or animal applications.
1. A method for collecting biochar fines from biochar for use in the water pathway of a water treatment process, wherein 95% of the biochar fines are between 0.1-0.5 mm in equivalent diameter, the method comprising the step of:
treating biochar with a treating solution; and
adding one or more flocculant and/or coagulant chemicals to the treating solution to create a biochar slurry.
2. The method of claim 1 further comprising the step of placing the biochar slurry in the water pathway of a water treatment process.
3. The method of claim 2 where the biochar slurry is de-watered prior to placing the biochar slurry in the water pathway of a water treatment process.
4. The method of claim 1 where the flocculants and/or coagulants chemicals improve the adsorptive properties of the biochar fines.
