Milkhouse Wastewater Report (pdf): This report describes milkhouse wastewater characteristics on five Brown County Dairy Farms. The collected data was used to determine what types of treatment systems would be viable and cost effective.

Maraven Report (pdf): During the period of December, 1995 Blue Diamond Water Treatment Company, of Two Rivers, Wisconsin and ESTR Inc. of Brussels, Wisconsin in conjunction with their local representatives, Servicios Blue Diamond de Venezuela, conducted a seminar in Caracas, Venezuela for Maraven. This seminar was presented to Mr. Jaime Gutierrez and Mr. Enrique Garcia Asesors de Protection Ambiental. This seminar focused on the recently developed and patented wastewater treatment technologies and their potential application in the treatment of production water and domestic waste from the oil platforms. Based on the response from this seminar, it was decided to do an on-site pilot test of the technologies to see if they are suited to treat these waste streams.

Pactiv Corporation Paper (pdf): ESTR Inc provided the hydrosparge which was used for ozone injection, as well as provided pilot plant and on site sampling, laboratory and analytical testing capability to assist in the evaluation of the new technology.

Iowa State Paper (pdf): ESTR, Inc. has also worked with Iowa State University's Department of Agriculture and Bio-systems Engineering to improve designs and efficiencies of odor control on manure lagoons. The cooperative effort efficiently reduces odor by treating the entire body of wastewater. The system, including patented ESTR technologies, has a direct impact on microbial interaction with dissolved ammonia providing a reduction in offensive odors.
