Sustainable sludge handling for the 21st Century
Purification of municipal and industrial waste waters leads to the generation of a residue-called “excess sludge”. This material when mechanically dewatered is typically 75-90% water. The balance of the dewatered sludge consists of organic compounds (solid waste, biomass) and inert materials (sand, salts, and metals). These sludges have been to date dehydrated to reduce the aqueous fraction ...

What Is Dissolved Air Flotation?
In dissolved air flotation (DAF), fine bubbles attach themselves to suspended matter in a liquid, floating them to the surface for removal Dissolved air flotation (DAF) is a water treatment technology often used for the pretreatment of source water, but what exactly does it entail and how does it fit in with other technologies? DAF is a type of coagulation-flocculation technology typically ...

Reusing water for industrial processes and irrigation in Saudi Arabia
Water is a scarce resource in Saudi Arabia and the public administration and private companies implement water reuse whenever possible. A reverse osmosis plant installed in the Eastern Province of Saudi Arabia helps to treat industrial waste water streams to quality levels that permit water reuse for industrial applications and irrigation. Kemira KemGuard antiscalant is used to prevent deposit ...

Industrial level cartridge filter – design, quality and description!
Cartridge filters refer to a simple piece of tubular filtration equipment which is designed for various industries for filtration requirements. The cartridge filters are most commonly used for filtration of water from all particles, chemicals, and other impurities. The cartridge filters are used to purify liquids, solvents, and water; it is designed to remove submicron particulates up to the size ...

How to Make Wastewater Treatment Flocculation Sustainable, Non Toxic, and Efficient
If you manage a water treatment plant or consult those who do, you know wastewater treatment flocculation is essential to delivering clean, safe, and reliable water. Following coagulation water treatment, flocculation encourages small, suspended particles in water to clump together into flocs, making them easy to be removed by post filtration. However, although flocculation helps remove ...

What is Ultrafiltration’s Role in Water Treatment?
Ultrafiltration with semipermeable membranes can play an important role in water purification because of its compactness and efficiency Ultrafiltration (UF) is a water purification process in which water is forced through a semipermeable membrane. Suspended solids and high-molecular-weight solutes remain on one side of the membrane, the retentate side, while water and low-molecular-weight ...

Interview with Pumps Africa Magazine: Solutions To Food Security and Clean Water in Africa
Africa’s water scarcity is not necessarily caused by a physical lack of water. In fact, much of the region is generally considered to suffer from what’s called “economic water scarcity,” which means that investments in water resources and relevant human capacity are not substantial enough to meet water demands in an area where the population does not have the financial ...

How has UF Water Treatment Systems Assisted Oil/Gas Companies
In the oil and gas industry, water and wastewater treatment comes into play in mining operations and refineries. UF water treatment systems are used in tertiary process applications in these industries to assist oil/gas operators and oil/gas refineries to obtain suitable water for produced water reuse for fracking operations or sustainable discharge. Mining for oil happens both on and off-shore. ...

How to Improve Water Availability in India
Water plays a critical role in sustaining societies, economies, and ecosystems—but it’s becoming increasingly scarce despite the growing demand. Experts predict that by 2030, global freshwater demand will outpace supply by 40% to 50%. For countries like India—now the world’s most populous nation—these stats are not encouraging. So, how do we improve water ...
