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.

A particle is provided for delivery of humics, and biochar that is water-dispersible into constituent granules. The resulting particles are amenable to broadcast application, for example via rotary or drop spreader. As a result, a dust-free particle is formed that simultaneously addresses the prior art problems of the friable nature of humics and the sooty dusting property of biochar to facilitate ease of handling, broadcast field spreading, and gain the synergistic effects of dosing soil with both humics and biochar. The particle provides improved storage capabilities for materials improving the quality of the delivered material and decreasing negative storage consequences such as odor emanation or degradation. The resulting particles upon dispersion have a pH of between 3.3 and 8.1.

The present invention discloses a mineral soil conditioner produced by coal ash and a preparation method thereof. The preparation method includes: (1) mixing coal ash with a heteroacid to form a mixture, stirring and filtering the mixture under the action of ultrasound to obtain a refined coal ash and a filtrate; (2) mixing the refined coal ash obtained in the step (1) with a calcium-based compound and a potassium-based compound well, performing drying with the residual heat of tail gas of a kiln after granulation; (3) performing calcination and activation continuously after granulation and drying in the step (2), then cooling, and processing by ball milling and molding to obtain a novel mineral soil conditioner. The present invention achieves the efficient utilization of a fuel coal by-product, namely, coal ash in agriculture and reduces the heavy metal content in coal ash and environmental contamination caused thereby.
