Perfectly, the trip from China to the Piscataway WRRF WSSC construction site was definitely lengthy, in aspect owing to COVID-19 and offer chain troubles encountered above the past several many years.
A crucial part of the thermal hydrolysis course of action (THP), the cooling heat exchangers (CHEX), are tube-type heat exchangers that decreased the sludge temperature leaving the thermal hydrolysis course of action from 194°F to 100°F prior to arrival at the anaerobic digestion tanks.
These individual models had been created with specialty superalloy piping, sourced out of China, to prevent microbial induced corrosion. The Computer system group produced the models for fabrication in December 2020 and diligently tracked their fabrication and shipping and delivery to the challenge internet site. On Monday, the prolonged journey formally finished. Immediately after a journey across the Pacific to Seattle and then across the place to Maryland, the products was delicately established on the ready concrete pads.
With the CHEX models, each weighing approximately 25,000 lbs, now set in their last posture, get the job done will proceed on the UV and Odor Control Facility as very well as piping interconnecting the THP, the CHEX models, and the anaerobic digesters.
