Comparative Evaluation of Membrane Bioreactor (MBR) and Sequencing Batch Reactor (SBR) Technologies for the Treatment of Landfill Leachate in Sri Lanka
Production of leachate and contamination of water bodies is a major concern in solid waste landfills. The generated leachate must be appropriately treated before being discharged into the environment. It can be treated by different physico-chemical and biological methods and their combinations. In this study, the performance of the membrane bioreactor (MBR) and sequencing batch …
Bio-Based Polyurethane Coatings
Bio-based polyurethane (PU) coatings are more sustainable compared with petroleum-based PU coatings because they can address the public concerns about the use of renewable resources and environmental impact. This review overviews the different categories of bio-based PU coatings: water-borne, solvent-less, powder, UV-curable, and hybrid coatings based on vegetable oils, lignocellulosic biomass, and carbohydrates. The development …
Groundwater Flow Modelling in a Tributary Catchment of the Badulu Oya River, Sri Lanka
This study investigates the regional groundwater flow patterns in the Rambukpotha Oya micro-catchment within the Badulu Oya basin by integrating Geographic Information System (GIS) techniques with numerical groundwater flow modeling. Despite the lack of previous studies on the groundwater flow system in this micro-catchment, the research utilized existing data and information to build a comprehensive …

An Extensive Review of Smart Grid Technology
This research article investigates the improvements and components of smart grid technologies designed to improve energy efficiency and operational reliability. The debate covers important topics such as Energy Management Systems (EMS) for optimizing energy production and consumption, Distribution Automation technologies for enhancing grid dependability, and Advanced Metering Infrastructure (AMI) for real-time data exchange. The study …
Effect of Biochar on Soil Properties – A Review
Biochar is produced by carbonizing organic matter under high temperatures in a little to no oxygen environment. There are seven key factors to evaluate biochar, including pH, volatile organic compound content, water holding capacity, ash content, density, pore volume, and surface volume. The choice of raw materials affects the end biochar product, changing its chemical …
