Process Tech, LLC (formerly Bio-Aeration Engineering, Inc.) is a soil, water and wastewater environmental remediation company with its main office in New Harmony Indiana and fabrication facility in Evansville, Indiana. We specialize in custom fabrication of aeration systems which provide low cost aeration solutions to the water and wastewater industry. Since each job and process control is different, every aeration system we install is different. Our team works to find the best low-cost solution that works for you! We treat the problem NOT the symptoms. We can demonstrate repeatable reduction solutions - in solids, ammonia, odor and activated sludge.
