Nanofiltration (NF) Process In Water and Wastewater Treatment
https://www.yasa.ltd/post/what-is-nanofiltration-nf-process-in-water-treatment Nanofiltration (NF) is a membrane treatment process primarily used to separate dissolved solutes from water. The process of movement of solvent through a semipermeable membrane from the solution to the pure solvent by applying excess pressure on the solution side is called nanofiltration. Nanofiltration (NF) ...

Wastewater treatment using bioreactor with dual functional ceramic membrane
A novel bioreactor including a group of dual functional ceramic membranes was developed and used for wastewater treatment. The ceramic membranes could be used for both aeration and filtration alternately, so fouling to ceramic membrane would be palliated effectively as its dual functions. For 100 days operation, COD removal ratio was 88∼97% for influent COD of 154∼1389 mg/L, and NH4+-N removal ...

Replacement of fresh water use by final effluent recovery in a highly optimized 100% recovered paper mill
A further closure of the water circuit in paper mills with a relative high optimization of their water network is limited by the increase of contamination in the water and runnability problems of the paper machine. Therefore, new strategies for saving water must be focussed on the treatment of final effluents of the paper mill, aiming to obtain high quality water that may replace fresh water use ...

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 ...

Preparation and characterization of fouling-resistant photocatalytic metal membrane embedded with self-organized TiO2 nano tube
A self-organized nano-structured, photocatalytic TiO2 membrane with large surface area of anatase crystallites was successfully fabricated by anodization. The nano-structured anodized TiO2 membrane was characterized using SEM, XRD and TEM techniques and the operational parameters to fabricate such as anodization time and applied anodic potential were also investigated. The anodized TiO2 membrane ...

Commissioning and operating submerged membrane bioreactors: a designer's perspective
Submerged Membrane Bioreactor (MBR) applications for wastewater treatment have taken off in recent years in New Zealand. From designer perspectives, the membrane modules replace the conventional secondary clarifier, thus eliminating solids settling issues and reducing plant footprint. This paper discusses the recent experiences of Harrison Grierson Consultants Limited designing and commissioning ...

Treatment of waste thermal waters by ozonation and nanofiltraton
After their use for heating, e.g. in greenhouses, waste thermal waters may cause environmental problems due to their high contents of ions, and in some cases organic matter (associated with an oxygen demand) or toxic compounds. The aims of this work were to decrease the high organic content of waste thermal water by a combination of ozone treatment and membrane separation, and to investigate ...

Degreasing Liquid Treatment
Degreasing is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials. Degreasing is performed with aid of an aqueous solution containing detergents. The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in degreasing treatment baths ...

Sustainability of decentralized wastewater treatment technologies
In many Countries, small communities are required to treat wastewater discharges to increasing standards of lesser environmental impacts, but must achieve that goal at locally sustainable costs. While biological membrane treatment (membrane bio-reactors (MBRs)) is quickly becoming the industry standard for centralized wastewater treatment plants, and would also be ideally suited also for ...

Dye wastewater treatment by using ceramic membrane bioreactor
Performance of a Micro-filtration Membrane Bioreactor (MMBR) for treatment of dye wastewater was investigated. The experimental results indicated that the removal efficiency for COD, TOC and colour was 85%, 85-90% and 70%, respectively, the effluent COD was below 70 mgl−1 on average. Gel layer resistance of COD was 10%. Particle size distribution of sludge in MMBR was 1-150 μm, and the average ...
