  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Comparative applications of bioreactor and shake-flask systems in the laboratory treatment of oily sludge

    This study investigates the remediation efficiencies of a locally fabricated bioreactor system and a shake-flask system, using samples of oily sludge with varying concentrations of NPK fertiliser. Hydrocarbon removal efficiency of 46% and 24.2% was recorded for the stirred slurries containing 15- and 0-g NPK, respectively, in the bioreactor; whereas values of 40.1%, 33.2% and 18.9%, respectively, ...

  • Laboratory, pilot and industrial-scale validation of numerically optimized reverse-flow gas cyclones

    This paper addresses the experimental validation of the optimum design of reverse-flow gas-cyclones, obtained through the solution of a numerical non-linear optimization problem, viz. maximizing cyclone collection. The simulation model is based on the predictive properties of a finite diffusivity model, where the particles' turbulent dispersion coefficient is estimated through an empirical ...

  • Laboratory Studies Using edible oils to support reductive dechlorination

    In laboratory microcosm tests, single additions of corn oil, beef tallow, melted corn oil margarine, coconut oil, corn oil, soybean oil, or partially hydrogenated soybean oil supported complete reductive dechlorination of perchloroethene (PCE) or trichloroethene (TCE) to ethene when a dechlorinating population was present. TOC production from the edible oils continued for up to 200 days. More ...

  • A laboratory assessment of the impact of brewery wastewater discharge on sulfide and methane production in a sewer

    The impact of brewery wastewater discharge on sulfide and methane production in a sewer was assessed. Experiments were carried out on laboratory scale sewer reactors consisting of both an experimental and a control reactor. The control reactor was intermittently fed with real fresh sewage while the experimental reactor was fed with a mixture of brewery and domestic wastewater at two different ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...
