Rein and Associates

Our company has worked for clients throughout the United States and Central America. Locally, we work for many municipalities and industrial organizations. Some of our current projects are listed below.

Management and Operating Assistance:

We have contracts with several clients to provide technical and management assistance for wastewater treatment plant operations. Included with these services are: licensed wastewater operators and laboratory technicians, the development of computer systems for plant operation, biosolids land application management, laboratory QA/QC manuals, and pretreatment coordination with industrial users.

We are implementing advanced asset management for a municipal wastewater/water facility and an industrial wastewater facility. We are using asset management software named, "TEAMS". This software was developed by the Maryland Center for Environmental Training (MCET) through a grant from EPA. This software incorporates all elements of advanced asset management. See our publications page for more information on the software.

Dehydrating Plant:

Several years ago we completed constuction of a new anaerobic treatment system for a potato and carrot dehydrating facility in Northern Minnesota. This low rate system is removing 85% of the organic load and producing 200 CFM of methane per day. We continue to provide operating assistance at this facility.

Biological Phosphorus Removal:

Several years ago, we designed a biological phosphorus upgrade to the Fergus Falls wastewater treatment plant. The primary purpose for the upgrade was to reduce chemical costs. However, an added benefit has been achieved - sludge production has been reduced by over 30%! This upgrade has resulted in substantial savings in operating costs. The plant consistantly meets a phosphorus discharge limit of 1 mg/L without the addition of any chemical.

In 2005, we completed a biological phosphorus (bio-p) removal pilot study for the city of Pelican Rapids. This study determined that their current plant configuration consisting of RBCs and a trickling filter was not capable of achieving bio-p; however, the pilot plant did indicate that by using a typical anaerobic-aerobic activated sludge configuration, bio-p removal was possible. Currenty, we are working with Interstate Engineering to determine the best solution for the city of Pelican Rapids.

Environmental Permitting:

We have recently been retained by a private industry to handle all environmental compliance requirements. Included are the following: air emission inventory reports, air permits, stormwater permits, and hazardous waste generator permits.
