Reverse osmosis (RO) is a widely utilized process that affects many aspects of our daily lives. For example, RO helps food manufacturers concentrate fruit juice, aquarium operators maintain their tanks, and cities and campers produce drinking water from something dirty or salty. It’s difficult to make it through a day without using a product created with reverse osmosis.
Since the invention of “resistance welding” in 1886 by Elihu Thomson, welding has been an ever-evolving process that has forever changed the manufacturing industry. At the conclusion of 2016, it continues to show no signs of slowing down. The welding industry continues to be a highly competent and cost-effective method for joining metals and non-metals, including plastics and composites.
Lasers were once a spotlight for science fiction, but now they are streamlining the manufacturing industry. Recent projections are now showing “Fiber Laser Cutting” is on the rise and expected to now become a key player in the Ultra Hard Material Cutting Machine market, which is expected to be a 1.8 billion dollar industry by 2024.
Sludge sounds unattractive, and indeed usually is. Defined as, “a muddy or slushy mass, deposit, or sediment,” it’s the kind of thick, viscous goo you’ll find at the bottom of a pond. The thought of activating it conjurors up images of some science-fiction blob slithering through your town or city.
That’s actually not too far from reality. While it’s probably not in your neighborhood, activated sludge may well be just outside your city limits. The good news is that it’s far from harmful. In fact it’s positively beneficial as it forms an essential component of many large-scale wastewater treatment systems.
Measuring fluid flow is difficult. To start with, there’s the question of whether to measure volume or mass. Then within each category there are multiple technologies to chose from. Cost rises with accuracy, and some high-precision methods lack robustness for industrial application, especially in large, distributed plant environments. That’s why, before committing to a flow measurement method, it’s important to step back and consider how the data will be used.
Ground-level ozone is a growing problem in many cities, especially on the US west coast. As noted by the EPA, it causes respiratory problems like throat irritation, tightness in the chest, and increased occurrence of asthma attacks. That’s why, on October 1st2015, the National Ambient Air Quality Standard was lowered from 75 to 70 ppbn. This has implications for the fuel burnt in automobile and truck engines, and supports increased use of compressed natural gas (CNG.) CNG for vehicles is delivered through specially-designed filling stations, which are good applications for ChemTec flow monitors and excess flow valves.
Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
Gas escaping from pipework needs to be detected quickly. Depending on the type of gas, the consequences range from merely wasteful to fatal. Leaking gas can be environmentally damaging, it can create an explosion risk, and it can even kill thousands of people, as happened in the Bhopal chemical plant disaster.
Every year more and more people voluntarily expose themselves to intense laser light. Lasers surround us at work and home, but they can be dangerous, so why would so many choose to do this? Two reasons: vanity and cost. Laser treatments, usually delivered in a clinic or spa setting, are an effective way of rejuvenating aging or damaged skin. They’re also cheaper than the more invasive alternatives. As a result, the market for these lasers is growing rapidly.
Mosquito Misting Systems
Summer is here, and with the long days and rising temperatures come the mosquitos. The top months for mosquito presence are June, July and August and no one is safe from mosquito borne illnesses like West Nile Virus. It’s time to protect your home and yourself, but how do you get rid of them?
