Mr. Sundine has more than 40 years of experience in the horticulture, wastewater, and environmental fields. Mr. Sundine graduated from Colorado State University with a degree in Horticulture. He is President and Chief Technical Officer of Sundine Enterprises, Inc., a soil and water consultancy company.  He is a specialist in both natural and mechanical water and wastewater remediation, insitu bioremediation, erosion control, soil amendments, biological oxygen, microalgae and weed control, oil patch production water and industrial reuse and reclamation, and animal waste remediation.  His specialty and experience is in the application of electrocoagulation used for the destabilization of contaminants in aqueous solutions. Electrocoagulation kills bacteria, viruses, and personal care products and is used in place of lime softening, chlorine, UV, and ozone.  Mr. Sundine has extensive experience with the marketing of products for both start-up companies (Innova Corporation) and for established companies (Sumitomo Corporation of America). Mr. Sundine is the national expert on Isolite®CG, a porous ceramic used in both bioremediation and the green industry. He has developed technical training and educational programs, and providing necessary research and development protocol for a variety of soil and water related studies. Mr. Sundine's responsiveness and thorough follow-up has earned him the respect of his peers and customers alike.

 

POSTER PRESENTATION

An Efficient Method of Removing Metals, Emerging Contaminants, and Pharmaceuticals from Wastestreams

Electrocoagulation [EC] will successfully remove heavy metals, silica, pharmaceuticals, and other emerging contaminants from aqueous solutions such as production wastewater. With the use of clean electricity, EC efficiently removes a wide range of contaminants with a single system. The EC makes constituents in the water “separable”. Heavy metals are converted from ion forms to oxide forms, allowing them to be disposed in a non-hazardous landfill. Because electrocoagulation utilizes methods that precipitate out large quantities of contaminants in one operation, the technology is the distinct economic and environmental choice for industrial, such as mining operations, commercial and municipal wastewater treatment. The capital and operating costs are usually significantly less than chemical coagulation and other treatment options. 

Untreated water is introduced into the bottom of the chamber and is dispersed evenly as it moves upward through the blades. Direct current is applied to the first and last blade. This results in a flood of electrons into the water, neutralizing charged particles, causing them to precipitate out of solution. In addition, the metal blades react to the current by releasing charged metal ions that act similar to chemical coagulants. The EC also contains an automated clean-in-place (CIP) system and an air purge system that fluidizes precipitants and reverses polarity in order to extend metal blade life and prevent contaminants from coating the blades. No chemicals, other than for CIP, are required for the treatment process. The acid solution used in the automated cleaning cycle is recycled and, when exhausted, is routed through the EC system for final disposal. EC has become recognized as a very effective means for economically treating a wide variety of challenging water treatment applications and is available in sizes ranging from 1.5 gpm to parallel multiples of 2,400 gpm.
