Membrane treatment of the bleaching plant (EPO) filtrate of a kraft pulp mill
The objective of this study was to evaluate the use of membrane technology to treat oxygen and peroxide-reinforced extraction stage (EPO) filtrate from a kraft pulp mill bleach plant. Three different types of tubular membranes were tested in a pilot plant: (i) tight ultrafiltration (UF); (ii) open UF followed by nanofiltration (UF + NF); and (iii) nanofiltration (NF). According to the ...

Simulation and optimization of an experimental membrane wastewater treatment plant using computational intelligence methods
The optimization of relaxation and filtration times of submerged microfiltration flat modules in membrane bioreactors used for municipal wastewater treatment is essential for efficient plant operation. However, the optimization and control of such plants and their filtration processes is a challenging problem due to the underlying highly nonlinear and complex processes. This paper presents the ...

Electrocoagulation: Effective Treatment of Silica Removal from Water
What is Silica? Silica, the second most abundant element on earth after oxygen, can be found in almost every water supply across the globe. Often known for being a hard and glassy mineral substance, this element can be found in numerous forms including sand, quartz, and granite. The mineral can be found in natural groundwater supplies in the forms of colloidal silica or reactive silica. While ...

Recycling of spent filter backwash water using coagulation-assisted membrane filtration: effects of submicrometre particles on membrane flux
Membrane separation technology has been widely used for recycling of spent filter backwash water (SFBW) in water treatment plant. Membrane filtration performance is subject to characteristics of the particles in the SFBW. A bench-scale microfiltration (MF) coupled with pre-coagulation was set up to evaluate the recovery efficiency of SFBW. Effect of particle size distribution and zeta potential ...

AMONCOURT, France: Skid–Elimination of turbidity and microbiological retention
In 1988, the town of Amoncourt fitted out with first drinking water treatment plant using Ultrafiltration membrane process: the world first. The plant's planned operational life was 7 years. It will haveoperated to full satisfaction for 15 years. The site was specially monitored by the Ministry of Health. On the basis of these results, it gave sanitary approval to the clarification-disinfection ...

Short- and long-term fouling characteristics of reverse osmosis membrane at full scale leachate treatment plant
This research is focused on characterizing the foulants on a reverse osmosis (RO) membrane taken from a full-scale leachate treatment plant in Thailand. The system consists of a physico-chemical pre-treatment unit and RO system and has been in operation for 2 years. Ferric chloride (FeCl3) was added to the open-jet sedimentation tank at 2.0–2.5 g/l dosage for chemical coagulation. The supernatant ...

Northwestern Lancaster, Pennsylvania - Case Study
In August 2011, AdEdge Water Technologies, LLC was contacted by Watek Engineering Corporation to design, manufacture and start up a nitrate removal system and a softening system for the Northwestern Lancaster County Authority in Manheim, Pennsylvania. The existing water system consisted of one well feeding water at 225 gpm to an elevated storage tank which feeds the distribution system. The ...

Assessment of water treatment processes: detailed organic matter characterisation and membrane fouling indices at the Loddon Water Treatment Plant, Victoria, Australia
Recent advances in membrane technology have led to its broad application, and reverse osmosis (RO) systems now represent the fastest growing segment of the desalination market. Its performance is hindered by membrane fouling. In this study pre-treatment methods to reduce RO fouling were investigated including flocculation, adsorption and ion exchange. Detailed organic characterisations were made ...

How to choose the Proper Membrane Cleaner
Cleaning filter membranes is a challenge faced by water treatment facilities across a variety of industries. In addition to municipal water treatment plants, wastewater treatment occurs in the automotive, metalworking, food & beverage, textile, parts cleaning, oil & gas, pharmaceutical, industrial manufacturing, and electronics industries. Keeping filter membranes clean is a concern to ...

Desalination: Looking to the future
Untitled Document Even though the volume of the earth's water is vast, less than 10 million of the 1 400 million cubic metres of water on the planet is of low salinity and suitable for use after applying conventional water treatment alone. The other 97.5% of the water on our planet is to be found in the oceans, where it is officially classified as seawater. Desalination ...

Tundra Tough - Treatment plants specially designed for cold climates provide a solution for two seasonal cabin complexes in Denali, Alaska - Case Study
Grizzly Bear Cabins and Campground in Dcnali, Alaska, needed a larger onsite system to handle a major expansion. Across the road, the undersized system for Dcnali River Cabins complex also needed replacement. Bio-Microbics engineer Reza Shams, Ph.D. helped design engineer Bob Tsigonis, PE., owner of Lifewater Engineering Co. in Fairbanks, to address numerous challenges. Both properties had ...

What will it take to get plastics out of the ocean?
From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards from shore, humpback ...
