In 1985, ADI was commissioned to design and conduct a seven month anaerobic pilot plant treatability study. The on-site pilot was to simulate a proposed full-scale, anaerobic process, and was to be operated at loadings and hydraulic retention times (HRT) anticipated in full-scale operation. The full-scale and pilot anaerobic technology chosen was the ADI-BVF. This is a low-rate digestion process which has proven advantages in the treatment of potato processing wastewaters. Advantages which made this technology the choice process included: ability to treat high concentration of SS, effective and reliable wastewater treatment, ability to absorb shock loads, economical construction and operation, digestion of waste solids from aerobic processes, energy production from biogas, and simplicity of operation.
