  • Case study - CAIROX CR potassium permanganate tablets

    PROBLEM Hydrogen sulfide (H2S) results from septic conditions during the collection and treatment of wastewater. H2S has long been recognized as a major problem for municipal wastewater systems. This colorless gas, known for its rotten egg smell, is produced by the biological reduction of sulfates and the decomposition of organic material. It forms at virtually every point in a system ...

  • Comparison of phosphorus recovery from incineration and gasification sewage sludge ash

    Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty ...

  • Optimization of copper removal from aqueous solutions in a continuous electrochemical cell divided by cellulosic separator

    Copper, as an inseparable part of many industrial discharges, threatens both public and environmental health. In this work, an electrochemical cell utilizing a cellulosic separator was used to evaluate Cu removal using graphite anodes and stainless steel cathodes in a continuous-flow mode reactor. In the experimental matrix, Cu concentration (1–5 mg L−1), electrolysis time (20–90 min), and ...

  • Chemical adsorption of oxytetracycline from aqueous solution by modified molecular sieves

    The removal of oxytetracycline (OTC) from aqueous solution on modified molecular sieve via adsorption was investigated in the present work. The copper(II) modified molecular sieve had the much higher adsorbed amount than unmodified one. The bigger pore, the more adsorption sites benefitted for the adsorbed amount of OTC. The exchanged amount of copper(II) and the acid-base property of solution ...

  • Utilization of two agrowastes for adsorption and removal of methylene blue: kinetics and isotherm studies

    Fresh water streams contaminated with synthetic dye-containing effluents pose a threat to aquatic and human life either by preventing aquatic photosynthesis or by entering into the food chain. Adsorptive removal of such dyes with potent biosorbents is an important technique to reduce bioaccumulation and biomagnifications of the dyes in human life. We report use of betel nut (BN) husk and ...

  • 2016 has been a momentous year

    Solving more waste management problems for more companies and organisations than ever before has been just one of our many achievements. At this time of year it is always good to look back over the previous twelve months and reflect on what we have achieved.  2016, we have to say, has been an excellent year for Matthews Environmental Solutions because in addition to overcoming a significant ...

  • Novel thermoresponsive assemblies of co-grafted natural and synthetic polymers for water purification

    Water contamination and its purification are a global problem. The current approach to purify water is reduction of impurities to acceptable levels. One of the ways to achieve this is by use of water-soluble polymers that extract organic and metallic contaminants, from water. This paper presents a blend of composite polymers that eliminates both the contaminants simultaneously by the principle ...

  • The Magic of Recycling

    “Magic, by its ability to capture the imagination, can change the world” – Cyril the Sorcerer. My presumptions about what makes for good recycling outreach were shattered in the wink of an eye on the day a magician restored a torn-up newspaper into a fully-recycled newspaper. From this point on buttons, posters, marketing, and even social media ...

  • CO2 Capture from Ambient Air by Crystallization with a Guanidine Sorbent

    Carbon capture and storage is an important strategy for stabilizing the increasing concentration of atmospheric CO2 and the global temperature. A possible approach toward reversing this trend and decreasing the atmospheric CO2 concentration is to remove the CO2 directly from air (direct air capture). Herein we report a simple aqueous guanidine sorbent that captures ...

  • Online waste water monitoring system on golfcourse - Case Study

    Validation of BACTcontrol as an online waste water Monitoring System and Microbiological Early Warning System. The presence of dangerous micro organisms in water used in food processing or surface water can be a real threat for human health. The constant monitoring and control of the presence of such dangerous pathogens is therefore of big importance. In a ...

  • Sustainability in the Scottish Highlands with Big Hanna

    In 2010 Glenmore Lodge installed a Big Hanna. Six years later we revisit to take a look at how Big Hanna is doing and what the staff think about composting. Has everything worked out, and is composting really as easy as we claimed it would be? Glenmore Lodge is situated in Cairngorms National Park in the Scottish Highlands, 40 miles (app 65 km) southeast of Inverness. It is Scotland’s ...

  • Are Fines Reducing Your Hydrocarbon Production?

    Although choosing frac sand can reduce completions design cost initially, there can be short-term and long-term issues: Proppant flowback, proppant embedment, and decreased fracture conductivity, in addition to fines, can negatively affect hydrocarbon production. What are fines? Fines are generated by crushing of proppant, by erosion of sand on the fracture face during treatment, ...

  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Why Chiller Efficiency and Maintenance are Key Facility Investments

    Typically, a chiller is the single largest consumer of power and most expensive piece of equipment in a building, so it’s logical to allocate time and budget towards energy efficiency and equipment maintenance. Without routine chiller maintenance, energy usage can double in just a ...
