How to Remove Nanoparticles from Your Drinking Water‍

Posted by Anthony DeLoach, President on Jul 22, 2022 1:14:33 PM

If you’ve been reading the news lately, you know nanoparticles are not so great. In everything from cosmetics to water filters, nanoparticles have been shown to cause various health problems. But what exactly are nanoparticles, and how can you protect yourself from their harmful effects? Let’s answer these questions and more with this quick guide on removing nanoparticles from your drinking water.

What are Nanoparticles?

Nano is a prefix that’s used to indicate how small something is. In the case of nanoparticles, it means particles less than 100 nanometers. Water filters that use nanoparticles are generally around 0.2 to 0.3 microns or 2,000 to 3,000 nanometers. That’s pretty small. There are some health concerns with nanoparticles. When ingested, they can cause inflammatory reactions in the body, disrupt normal organ function, and lead to a buildup of fluids in the lungs or other organs. A 2017 study found that the number of nanoparticles in drinking water is higher than expected and that using carbon filtration may make some nanoparticles more likely to leach into the water.

Where Are Nanoparticles Found?

Nanoparticles are found in a lot of modern products. Their small size makes them ideal for air and water filters, sunscreens, and cosmetics. It’s important to note that not all nanoparticles are harmful. Some are beneficial. Nanoparticles of silver are often added to water filters to help remove bacteria and other contaminants from drinking water. There are a few places where nanoparticles are most often found. - In water filters - Nanoparticles are often added to water filters to help remove bacteria and harmful contaminants. - In sunscreens - Some sunscreen products contain nanoparticles of zinc oxide, titanium dioxide, and other minerals that provide broad UV protection. - In cosmetics - Many makeups, lip balms, and other beauty products contain nanoparticles of iron, titanium dioxide, zinc oxide, and other minerals that help preserve the product and provide color.

A Quick Guide to Polymer 3D Printing Technology

Posted by Daniel DiDomenico on Jul 12, 2022 1:00:00 PM

3D printing is a technology that has only recently become commercially available.

Progress in the last decade has allowed the equipment to excel tremendously.

3D print technology was started in 1987 by 3D Systems Corporation. The technology gained traction in the early 2010s. 3D printing is a type of additive manufacturing that creates three-dimensional parts. By successively adding material layer by layer until the part is complete.

To create the part, a 3D CAD model is required. The potential of 3D printing has led to a wide variety of technologies on the market. This blog will go into depth on the most prevalent types of 3D printing and their applications.

Flow Measurement in Water Systems

Posted by Matthew C. Mossman P.E. on Sep 28, 2021 11:45:00 AM

In water treatment systems it is often important to measure the rate at which water is flowing through the system. Data from flow measurement devices can be used to control chemical dosing, set pump speeds, control filter loading rates, inform maintenance programs, and other tasks necessary for operation of a water treatment facility or on key components such as Degasification and Decarbonation systems or Biological Odor Control Systems. As with most types of instrumentation, there is an array of technologies that can be used for the task, each one with various strengths and optimal applications. For modern electronically controlled systems, the most common types of flow sensors used are axial turbine flowmeters, paddlewheel flowmeters, differential pressure / orifice plate flow transducers, and magnetic flowmeters. This article will briefly discuss the technology and features of each of these types.

A turbine flow meter,

consists of a tube that contains supports to hold a multi-bladed metal turbine in the center. The turbine is designed to have close clearance to the walls of the tubing such that nearly all of the water is made to flow through the turbine blades as it travels through the pipe. The turbine is supported on finely finished bearings so that the turbine will spin freely even under very low flows. As the turbine spins, a magnetic pickup located outside of the flowmeter housing is used to sense the tips of the turbine blade spinning past the pickup. An amplifier/transmitter is then used to amplify the pulses and either transmit them directly or convert the pulse frequency into an analog signal that is then sent to a programmable controller for further use elsewhere in the system. One advantage of a turbine flowmeter is that the electronics are separated from the fluid path. The magnetic pickup is the only electronic component, and it is installed outside of the turbine housing, reading the presence of the turbine blade tips through the wall of the sensor body. In clean water applications, this can be advantageous because the magnetic pickup can be replaced if needed without removing the turbine from service. However, the turbine itself covers most of the pipe area and creates back-pressure in the system, requiring increased pumping energy to move a given amount of water. In Industrial Water Treatment or Filtration Treatment,  turbines can also easily become fouled or jammed if they are used to measure water or other fluids with entrained solids, algae or bacteria cultures which cause significant accumulation, or corrosive chemical components that can degrade the turbine bearings.
