Y&S Candies – MBR Internals Installation

Key Accomplishments

• Installed membrane cases and associated diffuser components in accordance with the project installation requirements and ADI Systems' approved shop drawings.
• Coordinated installation activities with ADI Systems to accommodate the equipment arrangement, structural interfaces, and mechanical connections associated with the membrane treatment system.
• The installation was supported by a technical drawing package addressing membrane tank configuration, internal equipment arrangements, anaerobic membrane bioreactor sections, and associated process piping interfaces.
• JCC worked from the project-specific membrane internals documentation, including the referenced membrane installation manual and approved shop drawings for Tank No. 2.
• Supported integration of the membrane internals with the broader wastewater treatment expansion, including coordination with the separate process piping and system tie-in construction activities.
• Completed the contracted installation work as part of the facility's wastewater pretreatment expansion, demonstrating JCC's capabilities in specialized industrial wastewater treatment equipment installation.
• Johnston Construction Company performed membrane bioreactor internals installation services at the Y&S Candies wastewater pretreatment facility in Lancaster, Pennsylvania, for The Hershey Company. Working as Civil Subcontractor under ADI Systems, Inc., the project's Prime Contractor and Design-Builder, JCC was responsible for installing MBR internals, membrane cases, and diffuser assemblies associated with the wastewater treatment plant expansion.
• The project formed part of a larger expansion of the facility's anaerobic membrane bioreactor (AnMBR) wastewater treatment system. ADI Systems' design-build project incorporated additional membrane treatment infrastructure, process piping modifications, mechanical equipment, and associated treatment system components. Johnston Construction Company's separate installation contract focused specifically on the membrane internals required for the expanded treatment facilities.
• A significant component of JCC's work involved installation of the MBR 2 internals and associated membrane cases. These components formed part of the membrane treatment arrangement within the wastewater treatment system. Installation activities required placement of specialized equipment in accordance with the specified membrane tank configuration, installation procedures, and equipment arrangement requirements.
• The contracted work also included installation of diffuser assemblies associated with the membrane treatment system. These components were incorporated into the internal equipment arrangement in accordance with the applicable project documentation. Proper positioning and coordination of the membrane cases and diffuser assemblies were important to their integration with the surrounding treatment equipment and piping connections.
• The technical drawing package for the project addressed the MBR piping layout, submerged membrane unit (SMU) installation, AnMBR tank sections, flush piping, scour piping, permeate piping, and associated treatment system arrangements. These drawings established the broader mechanical configuration and equipment interfaces relevant to the membrane internals installation. JCC's contracted work was performed within this overall treatment system configuration.
• Coordination with ADI Systems was an important part of the installation process. The project required integration of membrane internals with the larger wastewater treatment expansion, including consideration of equipment locations, installation sequences, and interfaces with related mechanical systems. The membrane internals installation represented a separate construction work package from the facility's MBR piping and system tie-in improvements.
