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.

Odor control in a manufacturing facility is essential.

It prevents potential health risks and discomfort caused by the spread of chemicals, vapors, and fumes. Additionally, excessive vapors can hinder the efficiency of exhaust and natural ventilation systems.

One effective solution for addressing odor issues is the installation of an Odor Control Scrubber Tower. These towers are part of the ventilation system in manufacturing plants and chemical processing facilities.

Odor control scrubbers help to remove noxious fumes and odors from exhaust and air streams. This is an effective way to improve air quality. This process involves utilizing an activated carbon filter and an ionic air filter

Key Considerations for Installing an Odor Control Scrubber Tower:

Health and Safety of Workers:

Industrial environments pose risks of exposure to hazardous fumes and gases for workers. Unhealthy odors emitted in high concentrations can jeopardize their well-being and safety. In some cases, these gases may even be combustible, adding an extra level of danger.

Odor control scrubber towers remove gases from the contaminated air, ensuring a safe working environment. These towers reduce the risk of health issues such as nausea, headaches, allergy symptoms, eye irritation, and loss of consciousness. This helps maintain worker productivity and prevents sickness caused by toxic fumes and gases.

Water turbidity refers to how transparent or translucent the water is when examining or testing it for any use.

 Water turbidity can impact food and beverage, municipal, industrial, and aquaculture operations. Turbidity is caused by suspended or dissolved particles in the water that scatter light which causes the water to appear cloudy or even murky.

Different particles can cause turbidity, including sediments such as silts and clay, fine inorganic or organic matter, algae or soluble colored organic compounds, and microscopic organisms. Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit. The EPA requires a turbidity level no higher than 0.3 NTU in the USA, and if a member of the partnership of safe drinking water, then the level must not exceed 0.1 NTU.

High turbidity can create habitats for other harmful elements, such as bacteria or metals, that can accumulate onto the particles. This increases the health risk for a potable water system. In aquaculture operations, increased turbidity from silts and sediments can harm and harm marine life, so it must be removed to safe levels. For the food and beverage industry, the impact of high turbidity can be both a safety concern and a visual and noticeable quality concern because if the turbidity is high, it can alter the physical look of the final product, for example, a distillery.

The EPA and other world health organizations have sounded the alarm on the dangers and health impacts of being exposed to per- and polyfluoroalkyl substances (PFASs & PFOAs) also known as the forever chemicals.

In response, federal and state regulators are adopting new water quality guidelines and laws to address these contaminants in our drinking water systems and groundwater pollution. It's a pervasive issue, as PFASs can be found in various types and over 4,700 different variations, each with at least three polyfluorinated carbon atoms.

With more than 10,000 types of PFASs introduced into products, it's no wonder that the quality of drinking water in the USA and other countries has been compromised. But what exactly are PFASs? These are fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom. While they do not contain atoms like hydrogen, chlorine, bromine, or iodine, any chemical with a perfluorinated (CF3) or perfluorinated (CF2) component falls under the PFAS category. However, there are a few exceptions.

PFASs can be further classified into subgroups such as surfactants, perfluorosulfonic acids, perfluorooctane sulfonic acids, perfluorocarboxylic acids, and perfluorooctanoic acids (commonly referred to as PFOSs and PFOAs). These persistent organic pollutants, also known as "forever chemicals," pose a significant challenge due to their resistance to environmental degradation. As a result, they are found in humans, animals, and water supplies across the USA.

In water treatment, it is often required to remove small particulate matter from the raw water.

One of the most cost-effective ways to accomplish this is with a pressure filter. Sometimes referred to as “sand filters,” a pressure filter consists of a rigid filter vessel capable of withstanding internal pressure, combined with pipework to distribute and collect water and one or multiple types of filter media. Pressure filters are commonly used in municipal water systems, industrial facilities, residential well water systems, and swimming pools. Typical pressure filter construction is shown below:

 

At the top of the filter vessel, a distributor is used to break up and distribute the water flow so that there are no concentrated flow jets that stir up the media bed. Inflow distributors are usually oriented to direct flow at the top of the vessel to disperse the flow further. Below the distributor is the primary filter bed. The filter bed contains fine-grained media, most often sand, including crushed anthracite coal, activated charcoal, garnet, or other granular bulk products. The media bed is the thickest layer in the filter vessel and is the region that does the actual filtering of the water or other fluid. Below the media bed will be one or more support layers. These will usually be larger-sized gravel that is chosen to support the filter bed while allowing high flow through the support layer and into the outflow header. The outflow header can take several forms but is often composed of a large central pipe with multiple smaller pipes or “laterals” attached. The laterals are slotted or perforated. This allows the pressurized water to flow into the laterals and out through the outflow header into the downstream components of the water treatment system.

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 the 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.

Water treatment towers and storage tanks are high places that require special precautions when entering. While the majority of people who enter these locations for work can be trusted, there are some hazards that make it more important than usual to follow safety procedures.

These locations can get very hot and humid, and can also be filled with harmful chemicals and microorganisms that can cause serious health issues if inhaled or absorbed through the skin. Therefore, the general standard for workplace safety is much higher when entering locations like these.

Make sure you have read and understood the following information about safety when entering a water treatment plant. It will help you understand how to stay safe and protect yourself from harm when entering a water treatment plant. normal installation, maintenance, or even emergency repairs, it is often required to enter into a water treatment tower (degasifier, air stripper, decarbonator, or clear well/ storage tank). When this occurs, full safety protocols should be followed at all times, in accordance with OSHA regulations.  A tower or tank B classification is a "Confined Space" location. For more information visit the OSHA combined space regulations page.

In addition, there are other safety risks that an operator or technician can be exposed to while inside these types of closed locations. The risk can come from fumes of hydrogen sulfide (H2S), chlorine from an injection line, or a lack of oxygen O2. A proper confined space permit should be prepared and only technicians with proper training and certifications should enter into these types of confined spaces.

Industrial water treatment systems play a crucial role in maintaining the quality and sustainability of water used in various industrial processes. One of the key challenges faced by industries is the presence of dissolved gases, particularly carbon dioxide (CO2), and corrosive gases like hydrogen sulfide (H2S) in the water. These gases can have detrimental effects on equipment, cause pH imbalances, and even compromise the overall efficiency of industrial processes.
