Five Solutions to Remove Pfas from Water

Per- and polyfluoroalkyl substances, better known as PFAS, have become a serious challenge for the water sector as they are difficult to remove and even harder to destroy. As innovations continue to emerge, Aquatech Online looks at five solutions to tackling these harmful chemicals. What is PFAS? Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals, according to the Environmental Protection Agency. Often referred to as 'forever chemicals', these chemicals have been manufactured and used in industries across the world since the 1940s. As of July 2020, there are over 2,200 confirmed sites of PFAS contamination across all 50 states in the US. PFAS has been found in food packaging, commercial household products,

How Cameras Revolutionized The Plumbing and Drain Cleaning Industry

While working the General Pipe Cleaner’s booth at a trade show several years ago, I struck up a conversation with a drain cleaning pro who used our products. He looked around at the different items we had in the booth, pointed at our line of camera inspection systems and said, “You know, I just spent $1,500 getting my

Light Water Reactor Sustainability (LWRS) Program

The Light Water Reactor Sustainability (LWRS) program conducts research to develop technologies and other solutions to improve the economics and reliability, sustain the safety, and extend the operation of our nation’s fleet of nuclear power plants. It has two objectives with respect to long-term operations: (1) to provide science- and technology-based solutions to industry to overcome the current labor-intensive business model and associated practices; and (2) to manage the aging of systems, structures, and components (SSCs) so nuclear power plants can continue to operate safely and cost-effectively.

What Are Microfiltration Membranes?

Microfiltration is a low pressure separation process utilizing membranes with very open pore structures. Microfiltration filters can be made with both organic materials, such as polymer based membranes, as well as inorganic materials, such as ceramic or stainless steel. In selecting the appropriate membrane, spiral-wound polymeric microfiltration filters are often the starting point for consideration, based on spiral MF’s balance of durability, membrane area per unit, and significantly lower membrane unit cost, and equipment capital cost vs. ceramic and stainless options. MF Products Microfiltration membranes have the most open pore sizes of all polymeric membranes. With a pore size range of 0.1 to 10μm, microfiltration membranes are capable of separating large suspended solids such as

Biosolids Disposal And Reuse: Emerging Opportunities

Biosolids Reuse: Why Now? Biosolids reuse and land application is a decade-old strategy, yet we are seeing a current push to innovate as landfill space becomes limited and concern grows over greenhouse gas (GHG) emissions. In Ontario, plans are underway to develop and implement a food and organic waste disposal ban regulation under the Environmental Protection Act. The anticipated regulation would support the beneficial reuse of organic resources, including biosolids and sludge. Coming forth as both a necessity and an opportunity, reusing biosolids is one of the most sustainable ways to achieve a circular economy, ideally by eliminating waste and recovering renewable energy. Reuse Options New and evolving technologies have opened the door to many different resource recovery and reuse

Saudi Arabia’s desalination projects eye sustainability and energy

Saudi Arabia is leading the way with sustainable, energy-efficient desalination projects while maintaining its position as a world leader in desalinated water production. The Middle East and North African region have some of the lowest water availability levels per capita among the world’s most water-scarce regions. This makes the region heavily dependent on desalination, even though desalination directly impacts the issue of sustainability and renewable energy. Developers in the Kingdom, however, aim to maintain their plants and operations in line with the country’s Vision 2030 goals and its leadership position in desalinated water production. Saudi energy firm ACWA Power is moving away from thermal-powered systems and switching entirely to reverse osmosis plants to facilitate efficient

Desalination May Be Key To Averting Global Water Shortage, But It Will Take Time

Clean freshwater is critical for sustaining human life. However, 1.1 billion people lack access to it worldwide. Desalination represents an increasingly popular way of addressing this. Desalination is the process of extracting salt from saline water to make it drinkable. There are two main types of desalination. In the

Rosenberg Worley To Design World’s First Subsea Desalination Plant

Design of the world’s first subsea desalination plant has commenced at Rosenberg Worley in Stavanger, Norway. Waterise’s desalination concept has the potential to meet increasing demand for clean freshwater around the world. It provides a deep-water solution using an energy-efficient reverse osmosis filtration process.

Safe Remote Maintenance of Irrigation and Drainage Pumps

IIoT on construction sites: Turck’s cloud solution enables users and operators of Hüdig’s site dewatering solutions to have access to the device status at any time The Hüdig GmbH & Co. KG in Celle is a pump systems specialist manufactures products that include units for irrigation and dewatering. The irrigation pumps are generally used in agriculture. The drainage pumps are mainly used on construction sites where the groundwater has to be lowered during the construction phase. “These pumps have to run around the clock, because considerable financial damage is caused if the building site pit fills up with water,” explains Lennart Heers, sales manager at Hüdig. Technically, the dewatering pumps consist of two installed pumps. An air pump that creates a vacuum and sucks the water out of the

3 Corrosion Resistant Metal Coatings Compared

Lightweight metals have emerged as the go-to choice in a wide range of industries. Metals such as aluminium, titanium and now even magnesium have become vital in automotive, aerospace and many consumer applications. The combination of their abundance, exceptional strength-to-weight ratios and versatility means they are a preferred choice for product engineers all over the world. Some lightweight alloys offer superior corrosion resistance even when untreated, but it is inevitable that surface treatment will be necessary in a finish product, for performance, longevity and quality purposes. Magnesium is renowned for its poor corrosion resistance - but what is less well know is that some aluminium alloys, such as 2xxx, 7xxx and other high-strength families containing copper or other transition

Water Industry Innovations in 2018

As the human population of the world continues to grow rapidly, bridging the gap between supply and demand and providing access to safe, clean water has become a priority and a strategic imperative that must be continuously addressed. Thus, there is a clear need to seek out fresh ideas and new approaches to deal with the challenges of dwindling natural water supplies. Whilst there is still some methods to follow, advances in science and technology are helping to bridge this gap and drive the industry forward. The goal of many of these advances is to enhance sustainability and efficiency of production whilst reducing power usage and wastage to a minimum throughout water infrastructure networks. And the advances that will reach success will be scalable, at low cost, and ecologically

Desalination to the Rescue

The world has very little fresh water and it is running out. At tens of billions of tons yearly, the fresh water of the ice caps is falling into the salty sea which is already 97 percent of the world’s water. Rising sea levels will cause mayhem with the supplies of most of the world’s cities because they sit low down
