Title: Gregory J Mandigo: Innovator in Wastewater Treatment Solutions

Introduction

Gregory J Mandigo is an accomplished inventor based in Crivitz, Wisconsin, with a remarkable portfolio of five patents. His contributions primarily focus on the innovative treatment and recycling of wastewater, a critical area given the increasing global challenges surrounding water management and environmental sustainability.

Latest Patents

Among his latest inventions is a method for salt production from wastewater. This groundbreaking process addresses the prevalent issue of wastewater streams rich in sulfate and chloride, which are typically discharged into the environment without recovery. Mandigo's invention effectively recovers pure water for recycling and generates valuable pure salts such as sodium chloride (NaCl) and sodium sulfate (Na2SO4) for beneficial reuse. The method incorporates sequential crystallization of salt products with an intermediate purification step, enhancing the purity levels through the addition of a chemical reactant. Notably, this innovative process achieves zero liquid discharge, contributing to the conservation of water resources.

Another significant invention by Mandigo is a method for recycling deoiled water using counterflow falling-film evaporators. This technique is particularly effective for treating produced water, which often contains oils and other impurities. The system employs a vertical tube heat exchanger bundle that distributes the brine in a falling film along the tube walls. By enabling the evaporation of deoiled water while minimizing the evaporator sump volume, this technology offers several advantages over traditional vertical tube co-current flow evaporators. These include lower total installed costs and improved management of water chemistry.
