'The scrubber was now pulling an extraordinary 85,000 acfmOf exhaust-- a 34% increase in capacity.'
Why Are Spreadsheets Still Used in Fieldwork Management?
Spreadsheet software doesn’t cost a lot to license. Sometimes it doesn’t even have a subscription fee. Because of this, and because of the industry’s familiarity with spreadsheet software, many companies are still trying to manage their entire portfolio of site data in Excel. Not matter how you slice it, getting up-to-date information to several different fieldwork teams - spread across dozens of active sites in a portfolio of hundreds - is a big job. Then compiling the incoming data into a...
Don’t Let the Welding Fume Plume Make You Sick
What’s at Stake? Welding poses a unique combination of both safety and health risks to more than 500,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers over a working lifetime. What’s the Danger? The fume plume is the clearly visible column of fume that rises directly from the spot of welding or cutting. Gases from the plume such as helium, argon, and carbon dioxide displace oxygen in the air and can lead to suffocation,...
Pet Crematorium - Bespoke pet cremation facility - Case Study
TodaySure have installed numerous pet crematoria, throughout the World. Our most recent innovative design incorporated two stacked individual pet cremators, fuelled by the exhaust gases of the adjacent automatically loaded mass burn unit, thus minimising fuel input and reducing carbon emissions.
Simultaneous regeneration of exhausted zeolite and nitrogen recovery using an air stripping method ...
Ammonium nitrogen recovery using natural zeolite from the permeates of anaerobic membrane bioreactors was investigated with batch and continuous experiments. Regeneration of exhausted zeolite was compared between mechanical shaking and air stripping, and experimental results showed the superiority of air stripping over the shaking. Liquid circulation and air flow rates were optimized in a continuous zeolite-packed column with a separate recovery system consisting of a regeneration chamber and a stripping column....
High Rate Biological Odour Control Demonstration for Biosolids Exhausts
Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of organic sulphur compounds (OSC), and has proven its effectiveness over more than 2 years of operation. OSC removal efficiencies...
