Project: Citrus Processing IWWTP Upgrades
Scope of Work: Wastewater Design
A citrus processing facility retained Environmental Engineering Consultants to review existing operational data of an Industrial Wastewater Treatment Plant in central Florida. For this IWWTP Project EEC provided the engineering performance specifications, project budget and price estimation, contractor / vendor bid packages, IWWTP Permit modification package, performance based specifications, a current site plan with modification overlay and piping and instrumentation diagram/drawing (P&ID) for the upgrade of an existing IWWTP at a citrus fruit processing facility. This facility generates a maximum of 5.6 MGD of combined process and domestic wastewater effluent. The existing industrial wastewater treatment plant utilized an Aerated Lagoon and secondary clarifier to process the wastewater generated during manufacturing operations. All proposed modifications to the existing system were to improve Water Quality Treatment and reliability of the Industrial Wastewater Treatment Plant. The essential character of the Biological Treatment System did not change, however specific pieces of equipment were added or relocated in order to provide the improvement.
Major Equipment Installed in IWWTP upgrade
• Primary Dissolved Air Flotation Unit
• Rotary Screen
• Secondary Dissolved Air Flotation Unit
• Four Wilo Submersible Wastewater Pumps
• 30 Aspirator Type Floating Aerators 30 horsepower each
• (3) Floating Aerator 40 horsepower
EEC collaborated with the environmental manager of the facility to provide upgrade scenarios including aeration, clarifier and dissolved air flotation. The entire flow pattern was reconfigured, as well as a new Mixed Liquor Suspended Solids Pumping Station was added. The construction modification was permitted through the Southwest District of the FDEP. In addition to design consultation, EEC prepared Construction Plans and Performance Specifications. EEC also solicited knowledgeable wastewater contractors to bid the project and helped the client evaluate the construction bids. The construction monitoring and oversight was provided by the client, but EEC prepared the as-built drawings and Certifications of Completion to the FDEP.
