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 ...

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 ...

Design of Ventilation and Deodorization System for Sludge Drying Workshop of Underground Sewage Treatment Plant
With the rapid development of the city, the number of sewage treatment plants and sewage treatment capacity increase simultaneously, leading to a rapid increase in the amount of sludge. In the past, concentrated sludge was only treated to 80% water content by mechanical dehydration before relevant disposal. There are secondary pollution and other problems that seriously affect the sustainable ...

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 ...

Transparent exopolymer particles: Potential agents for organic fouling and
Transparent exopolymer particles (TEP) are ubiquitous in marine and freshwaters, and have been subject to intensive study by oceanographers and limnologists over the past 15 years. These microscopic organic particles (visualized by Alcian Blue staining for acid polysaccharides) may be considered a planktonic form of exopolymeric substances (EPS). Two aspects relating to the potential involvement ...
