Why We Are Able To Solve These Problems

With our hands-on experience in designing and building wastewater treatment systems, we have acquired the knowledge to overcome the obstacles listed above. Having built wastewater treatment plants, collection systems, pump stations, chemical feed equipment, and control panels, we have improved our designs to prevent these issues from occurring in our plants. Originally, earthTek designed and built the first low pressure sewers with grinder pumps, recirculating media filters, and drip irrigation systems in the State of Indiana. Additionally, we also designed and built the first “modern” municipal SBR plant in Indiana.

At earthTek, we aren’t satisfied with mediocre. We want our systems to be great, work great, and to provide our customers with a positive and stress-free experience throughout the entire process.

How We Solve These Problems

Our wastewater treatment plants solve the issues described above. We custom design each plant to meet the requirements of that specific project. We utilize state-of-the-art computer analysis to model the design to ensure the plant will perform as expected. Complete with built-in capacity for higher than expected organic or hydraulic loads.
Our SABRE sequencing batch reactor (SBR) contains built-in speed adjustments, which automatically operate the plant at the proper speed for the current daily flows.

The SABRE SBR eliminates the need for return sludge, the problems of return flow rate adjustments, and the issue of clogged pipes. In addition, the SABRE SBR has no clarifier, which eliminates solids washout and scum. We utilize dissolved oxygen sensors and variable frequency drives (VFD’s) to automatically adjust the airflow to the amount needed for the process. earthTek also employs separate mixing to ensure all solids stay in suspension.

Lower temperatures do not pose a problem in our plants due to our tanks typically being buried below grade, which maintains a constant temperature year-round. This provides excellent ammonia nitrogen oxidation, and eliminates freezing issues in cold climates.
earthTek typically provides primary treatment, which eliminates most fats, oils, and grease (FOG), and the scum associated with the FOG. Primary treatment also reduces organic loading, energy use, and provides free anaerobic digestion of waste sludge.

  • Energy Efficiency: The SABRE SBR is designed to operate with minimal energy consumption. By optimizing the sequencing and aeration patterns, energy requirements for mixing and aeration can be reduced, resulting in lower operational costs and environmental impact.
  • Process Control: The SABRE SBR is highly automated, which provides excellent control over the entire treatment process. The ability to program and adjust the sequencing of the different treatment stages allows for precise control of process parameters, optimizing treatment efficiency and performance.
  • Sludge Management: The SABRE SBR process produces a more settleable and compact sludge compared to other treatment methods. This facilitates easier and more efficient sludge handling, dewatering, and disposal, reducing overall operational costs.
  • Odor Control: The batch operation of the SABRE SBR minimizes odor issues commonly associated with continuous flow treatment systems. Our enclosed and buried tank design prevents the release of odorous gasses, improving the overall odor control of the treatment plant. We frequently get told that people don’t even realize it is a wastewater treatment plant.
  • Ease of Retrofitting and Upgrading: SABRE SBR’s can easily be retrofitted into existing wastewater treatment plants, or used for upgrading older treatment facilities. The modular nature of our SBR process allows for gradual expansion or modification of the treatment capacity to meet future requirements.
