Growing of mankind, society, science and technology in our world is reaching to higher level of human civilization. Therefore, a sustainable treatment procedures are required in order to prevent the consequences of growing civilized situation to the environment. Magnetism has been used as physical treatment for particles or contaminants removal from wastewater. In this experiment, comparison between locations of steel wool has been carried out in order to determine the highest suspended solid removal. Variables has been set such as magnetic strength was 1.4Tesla, flow rate was 1mL/s, 80 gram of steel wool and experiment took 24 hours of circulation time and data recorded for 24 hours. Data were recorded involving control, non-inverted magnet and inverted magnet structure. Non-inverted magnets consists of magnets on same poles while inverted magnet on different poles. As a result, steel wool located inside of pipe was exhibited the highest removal (88.2%) compared to outside of the pipe (83.3%) and both occurred in inverted magnet structure. Therefore, it was indicated that longer exposure time to magnet resulted in greater improvement in removing pollutant. The results obtained and suggests that steel wool located inside of tube with inverted magnet position can be successfully treat wastewater effectively.

The use of conventional flocculants such as Aluminum sulphate (Alum) alone to treat the wastewater may be insufficient to get the required turbidity, suspended solids removal as well as it requires relatively a long residence time. Magnetic flocculation is one of the used techniques for increase the efficiency of the turbidity removal. In the present study, three sets of experiments are carried out in order to investigate the possibility of increasing the suspended solid removal efficiency from Al Doura oil refinery wastewater using iron oxide (Fe3O4), Nickel (Ni), and Cobalt (Co) ferromagnetic powders with alum. The following operating conditions namely, pH, alum dose, ferromagnetic powder dose, and initial turbidity are studied. The results revealed that an improvement in turbidity removal efficiency is satisfied, as well as, a reasonable reduction in the sedimentation period is achieved. The highest turbidity removal is 99.88% that obtained for 122NTU sample for alum dose 120 mg/L+ Nickel dose of 80mg/L and pH of 6.5.

Several studies have described the effectiveness of vegetated buffer strips, interposed between the cultivated areas and water bodies, in removal of suspended solids and other pollutants such as Glyphosate conveyed through surface runoff. This monitoring study has quantified the effects of a 5-metre wide herbaceous buffer zone, adjacent to a vineyard, built according to the Standard 5.2 of Cross-compliance (M.D. 27417). The amount of runoff generated was 3.9% of the total annual rainfall, with negligible differences in terms of volume after flowing through the buffer zone. The effectiveness of the buffer zone in suspended solids removal was, in terms of mass balance, of 45.5%. The glyphosate outputs from the vineyard, unlike in other experiences, were negligible and therefore it was not possible to evaluate the efficiency of the buffer zone in removing it. This is due to the low rainfall occurred in the period following distribution that has favoured <em>in situ</em> degradation of Glyphosate.

The paper presents the results of analyzes of the granulometric composition of suspended solids in backwash water from biological activated carbon (BAC) filters and its changes during sedimentation. Backwash water samples were taken during backwashing of two pilot filters after different filtration time. It was found that regardless of the concentration of suspended solids in the collected backwash water, particle sizes vs. their percentage volume contributions for all samples were similar. Particle sizes were in the range of 2–100 μm. However, the two-hour sedimentation for most of the samples proved to be effective (total suspended solids removal up to 93%), which is caused by self-coagulation of the sample.

Solids Removal

At the outlet of the Vermicelli catchment—a peri-urban area located in the campus of University of Calabria (Cosenza, Southern Italy)—a sedimentation tank is located, aiming at collecting the basin surface runoff and improve its quality. First, experimental results of the treatment effects are here presented and analyzed. In addition, a monitoring campaign was conducted in order to characterize the particles transported by surface runoff and to determine the treatment efficiency of the tank. The analysis showed the presence of a pollutant load in the surface runoff of the Vermicelli basin and provided information on its particle-size distribution (PSD). Results were considered in terms of the treatment efficiency of the sedimentation tank, showing a good overall removal efficiency value, together with a high variability of the removal sedimentation efficiency. This variability is mainly due to the different grain size of the suspended solids and the characteristics of the rainfall event.

The aim of this research is to evaluate the feasibility of the fibrous media for removal of total suspended solid and oil grease from palm oil mill effluent (POME). Wet lay-up method was adopted for filter fabrication where empty fruit bunches (EFB) were matted together with chitosan in non-woven manner. Chitosan-filled filter media were tested for their ability to reduce Total Suspended Solids (TSS) and Oil & Grease (O&G) from palm oil mill effluent. Filtration process results indicated that chitosan-filled filter media filtration only removed up to 28.14% of TSS and 29.86% of O&G.

Abstract A study of the Yamaska River in Québec in the period 1985-1987 has revealed the occurrence of fifteen dyes in water, suspended solids and sediment downstream from textile mills. The dyes were found in 1985 and 1986, but not in 1987, possibly because of improved waste treatment procedures. The most contaminated area was downstream from Granby, which has the largest concentration of textile mills in the basin. Three dyes were positively identified — Disperse Red 60, Disperse Blue 26 and Disperse Blue 79, the most widely used dye in the world. In addition, a mutagenic degradation product of Disperse Blue 79, 2-bromo-4,6-dmitroaniline, was identified in sediment at a location about 6 km downstream from Granby. This product is a result of the reductive cleavage of the azo bond of Disperse Blue 79 in anaerobic sediments. Most of the dyes found are expected to be moderately stable in aerobic environments, but may degrade under anaerobic conditions. This is the first demonstration of the occurrence of dyes in the Canadian environment.
