Title: Sohan Lal Daga: Innovator in Water Desalination and Potash Recovery

Introduction

Sohan Lal Daga is a notable inventor based in Gujarat, India. He has made significant contributions to the fields of water desalination and potash recovery. With a total of 6 patents to his name, Daga's work focuses on innovative solutions that address critical resource challenges.

Latest Patents

One of Daga's latest inventions is an animal-powered mechanical device for water desalination. This device utilizes animal power as a prime mover to desalinate brackish water. It features a unique mechanism that converts high-torque, low-speed animal energy into low-torque, high-speed energy to operate a high-pressure pump. The pump is connected to a reverse osmosis membrane module, enabling villages to obtain safe drinking water from brackish groundwater or seawater resources.

Another significant patent is a process for the recovery of sulphate of potash (SOP) from sulphate-rich bittern. This integrated process uses bittern and lime as raw materials. It involves fractional crystallization to obtain kainite type mixed salt, which is then converted to schoenite. The process further reacts with muriate of potash (MOP) to produce SOP. The method ensures that liquid streams containing potash are recycled, achieving quantitative recovery of potash in the form of SOP.
