Abstract:

Flocculation has been widely adopted as one of the most effective methods to remove colloidal particles in water or wastewater treatment. Synthetic flocculants are conventionally used because of their high flocculating efficiency and cost-effectiveness. However, they have been reported to have hazardous properties and implicated in some serious health problems including senile dementia and neuro-toxicity, as well as being recalcitrant in the environment. Consequently, efforts are being geared away from the use of synthetic flocculants in water and wastewater treatment. Hence, the need for safe

Tjörn is a cluster of islands, located in Västra Götaland’s county, on the west coast of Sweden. A fishing industry called Kädesholmen Seafood AB is located at Kädesholmen, one of the larger islands of Tjörn. The industry produces different types of fish preserves. The resulting waste water is polluted with mostly nutrients and organic matter in high concentrations. In lack of other treatment alternatives, the waste water is collected and transported to Trollhättan for biological degradation.

Bioflocculants produced by two identified bacteria: Actinobacterium sp. Mayor and Methylobacterium sp. Obi were investigated with regard to their physicochemical and flocculating characteristics.

The optimum culture conditions for the bioflocculant production were similar for all strains except in the case of Actinobacterium sp. Mayor and the consortium, where glucose was replaced by sodium carbonate as a carbon source. Multi-nitrogen source was the best nitrogen source compare to individual sources for both strains.

Abstract:

In Nordic countries, surface water is a common source for potable water production. Such waters are often characterised by high Natural Organic Matter (NOM) content, resulting in high colour, very low turbidity, low alkalinity and low hardness due to natural conditions. Treatment of such waters basically comprises the removal of NOM and colour, corrosion control and disinfection. Although the largest part of NOM is not harmful, some fractions can cause colour, taste and odour problems or can even be toxic.

Abstract:

As populations continue to grow, the demand for fresh drinking water is increasing. This puts a lot of pressure on drinking water producers to strive for more efficient solutions and techniques. Many producers worldwide use surface water as a raw water source, which they often treat through coagulation and flocculation techniques. This is done by adding coagulant (e.g. metal coagulants), creating instability in the suspension, causing flocculation. In this work, PIX-311 (a FeCl3 coagulant produced by Kemira) and Al2(SO4)3 (Kemwater ALG) were used as primary coagulants and CaCl2 (produced by TE

Abstract:

<p> Jar testing is one of the most common tools that water treatment facilities use to determine the treatment conditions necessary to meet finished water quality goals. A six-place stirrer is normally used for jar testing to provide identical mixing conditions while coagulant dose and pH vary in each jar to create “floc” that is removed via sedimentation. There are some utilities that are unable to utilize jar testing, since the current jar testing procedures do not identify optimum treatment conditions for their water supply. This is particularly true for those utilities treating

Coagulation and flocculation processes are important parts of water and wastewater treatment. Coagulation or destabilization of colloidal suspensions results in aggregation of colloidal particles by physical and chemical processes. Flocculation results in the formation of larger and settleable structures by bridging. Alginate, a polysaccharide obtained from marine brown algae, produces a gel structure when mixed with calcium ions, which is expected to be a potential coagulant in water treatment.

Abstract:

The aim of this research was to find a suitable alternative medium of scarce freshwater for textile dyeing, and to recycle and reuse the dyebath using a combined coagulation/flocculation and novel filter media. Simulated seawater (SSW) was tested as the alternative dyeing medium with a salt concentration of 3.5% where NaCl was the major component. Fibre/dye systems of wool/acid and metal complex, wool/reactive, polyester/disperse, nylon/acid and metal complex, and acrylic/cationicdyes were tested in simulated seawater and the performances of dyed fabric were compared to conventional dyeing sys

Abstract:

A proposta deste trabalho foi utilizar quatro diferentes coagulantes - sulfato de alumínio, cloreto férrico, hidroxicloreto de aluminio e sulfato ferrico; construir os diagramas de coagulação; e assimilar as regiões de maior ou menor eficiência da remoção de turbidez ou da cor. Para permitir uma avaliação de custos na utilização dos coagulantes, observo-se nos diagramas as regiões onde os valores de turbidez remanescente são aproximadamente iguais para diferentes coagulantes. Com essa consideração, foi stabelecida a relação entre consumo e custo dos produtos quimícos utilizados. Os coagulantes

Abstract:

The provision of clean drinking water typically involves treatment processes to remove contaminants. The conventional process involves coagulation with hydrolysing metal salts, typically of aluminium (‘alum’) or trivalent iron (‘ferric’). Along with the product water this also produces a waste by-product, or sludge. The fact of increasing sludge production — due to higher levels of treatment and greater volume of water supply — conflicts with modern demands for environmental best practice, leading to higher financial costs. A further issue is the significant quantity of water that is held

Abstract:

The Ceratium species occurring in the Vaal River since 2000, was identified as Ceratium hirundinella (O.F. Müller) Dujardin as proposed by Van Ginkel et al (2001). Ceratium hirundinella is known to cause problems in drinking water purification and has been penetrating into the final drinking water of Rand Water since 2006. Ceratium hirundinella is associated with many other water purification problems such as disrupting of the coagulation and flocculation processes, blocking of sand filters and algal penetration into the drinking water. Ceratium hirundinella also produce fishy taste and odorou

Abstract:

The goal of this thesis was to determine the operational and technical parameters of the separation objects in water treatment. The first part is a theoretical and provides basic information on this issue. The second part contains the evaluation criteria created by the obtained information for individual objects and gained in practice by personal visits of selected treatment plants of water. In the last part we can find application of these criteria in water treatment in practice. There is also included the final evaluation of the researched condition.

For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter.
