Sofi Filter efficiently removed 96.2 % - 97.9% TSS from purifying cooling water in Steel plant.Background: For decades steel manufacturers are relying on Sand Filter technology for total suspended solids (TSS) removal in wastewater treatment. However, this conventional technology fails to efficiently remove small colloidal particles which causes scaling, biofilms, and corrosion in the cooling ...
EnviroChemie supplied an Envopur® microfiltration plant as part of the glycol-water mixture regeneration plant. ...
PERFORMANCE TEST OF INDUSTRIAL SELF-CLEANING SOFI FILTER WITH 1 AND 10 pm ELEMENTS. Sofi Filtration together with Dow Chemical Company conducted tests with Sofi Filter, self-cleaning micro-filtration technology, in order to evaluate the technology's performance under different feed conditions. The testing was done in August 2013 at Aalto University premises, Espoo, Finland. This paper introduces ...
Such fouling can be very difficult to clean using commodity chemicals or even speciality chemicals. This paper explores the use of a novel cleaning process designed to increase the efficiency of membrane cleaning using microbubbles. ...
A comparison of two different medium scale MBRs (ultrafiltration and microfiltration) using respirometric methods has been achieved. The ultrafiltration membrane plant (0.034 µm pore size) maintained recirculation sludge flow at seven times the influent flow, and membranes were backwashed every 5 min and chemically cleaned weekly. The ...
The effect of algae in the early, mid and late phases of growth on membrane fouling, chemical coagulation (alum or aluminium chlorohydrate (ACH)) and hydraulic cleaning on the microfiltration of this effluent was investigated. The effect of M. aeruginosa in the early phase was negligible and gave a similar flux profile and permeate volume to that of effluent ...
This paper investigates the impact of Microcystis aeruginosa in a secondary effluent on the microfiltration filterability and cleaning of the membrane. Alum coagulation and dissolved air flotation (DAF) were investigated to remove the algae and so enhance the volume of effluent processed, and their influence on reversible and irreversible fouling. ...
