Environmental Engineering Laboratory

Department of Civil Engineering | BUBT

📌 Overview

The Environmental Engineering Laboratory, under the Department of Civil Engineering at BUBT, is dedicated to the analysis of water and wastewater quality. It supports the CE 2172: Environmental Engineering Lab course, undergraduate thesis and project work, and faculty research. The lab handles comprehensive parameters such as pH, color, turbidity, total solids, total dissolved solids (TDS), total suspended solids (TSS), carbon dioxide, alkalinity, hardness, chloride, iron, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and arsenic. Testing is systematically conducted in accordance with APHA Standard Methods for the Examination of Water and Wastewater, ASTM standards, and other national/international guidelines, providing students with practical experience in environmental monitoring, pollution assessment, and treatment processes.

🎯 Objectives

• Familiarize students with standard analytical procedures used for the physical, chemical, and microbiological characterization of water and wastewater.
• Provide hands-on experience in operating analytical instruments such as digital pH meters, spectrophotometers, DO meters, and turbidity meters.
• Enable students to determine key water quality criteria and understand pollution indicators along with their environmental and public health significance.
• Bridge the gap between classroom theory and real-world environmental engineering practices through guided chemical and gravimetric laboratory investigations.
• Train students in accurate sample preservation, technical data recording, regulatory result analysis, and scientific report writing.

🎓 Learning Outcomes

Upon successful completion of this laboratory course, students will be able to:

• Apply standard analytical metrics to quantitatively measure the raw physical, chemical, and baseline microbiological loads in fluid fields.
• Operate complex chemical monitoring gear safely, including specialized vacuum equipment, thermal ovens, and spectrophotometric instruments.
• Analyze and evaluate collected metrics alongside the regulatory boundary sets found in the Bangladesh Environment Conservation Rules and international guidelines.
• Isolate variance factors or analytical limitations and judge the integrity of experimental findings.
• Correlate quantified laboratory findings with real-world engineering remediation, ecosystem health, and community safety applications.
• Produce comprehensive, high-quality technical records and reports tracking calculated data and final engineering conclusions.
