  • Patent number: 10793480
    Abstract: The present invention provides a method for the preparation of multi-nutrient potassic fertilizer, by recovering potassium from sugarcane molasses based alcohol distillery effluent (commonly known as ‘spent wash’). The process involves pre-treatment of spent wash to clarify the aqueous phase and utilization of the treated spent wash in production of potassic fertilizer. The present invention enables utilisation of spent wash for recovery of value-added product (viz., potash fertiliser of >99% purity) and improves ease of ‘Zero Liquid Discharge’ compliance by subjecting the relatively benign process effluent to industrially practiced techniques for water recovery and salt reclamation.

  • Patent number: 10752515
    Abstract: The present invention describes a lithium-substituted magnesium ferrite material based hydroelectric cell and process for preparation thereof. A novel galvanic cell process of generating electric current in distilled water by lithium substituted magnesium ferrite hydroelectric cell has been developed. A synthesis process of ferrite pellet having zinc anode and silver inert electrode has been developed. The material splits water molecules and conducts ions within porous ferrite. Split ions electrochemically react with electrodes and form zinc hydroxide at anode and hydrogen gas at silver electrode. This hydroelectric cell has generated 5 mA short circuit current and 950 mV open cell voltage. Current increased to 20 mA by thermally deposited Zn electrode on a ferrite pellet. The cell is very economical and highly sensitive towards electrolysis of water molecules. It is a green source for producing energy and has a potential to excel from existing electrochemical batteries.
