Overview

In 2017, Napier-Reid provided a Dissolved Air Flotation (DAF) and Sequencing Batch Reactor (SBR) package to a crude oil industrial complex in latin america that processes more than 158,000 barrels of oil a day.

The plant is designed to treat an average flow of 794.4 m³/day, with a total suspended solid level of up to 40 mg/L, a FOG level of up to 35 mg/L, a COD up to 800 mg/L, and a BOD₅ up to 450 mg/L, at 15-27 °C. The plant produces an effluent flow with less than or equal to 33 mg/L of suspended solids, less than or equal to 17 mg/L of oil and grease, a COD < 160 mg/L, and a BOD₅ ≤ 45 mg/L.

The scope of supply for the project includes: a steel holding tank, a DAF system, a package SBR system, and a chemical dosing system consisting of: dosing packages for caustic soda, citric acid, phosphoric acid, demulsifier, coagulants and flocculants, and a chlorine disinfection system. Control equipment and various types of general equipment are also included.
