Anaerobic treatment of sulphate-rich wastewaters
Anaerobic treatment of sulphate-rich wastewater can nevertheless be applied successfully provided a proper treatment strategy is selected. The strategies currently available are discussed in relation to the aim of the treatment: i) removal of organic matter, ii) removal of sulphate or iii) removal of both.
Sulphate Reduction Unit (SRU) In an oil production environment, seawater is injected into a reservoir to maintain pressure and ensure that hydrocarbons are channeled to the producing well. The quality of water for injection has to meet a certain water quality to prevent plugging / scaling of the injection equipment.
Removal of High-Concentration Sulfate Ions from the Sodium
The feasibility of removal of sulfate ions from the sodium alkali FGD wastewater using the ettringite precipitation method was evaluated. Factors affecting the removal of sulfate ions, such as NaAlO 2 dosage, Ca(OH) 2 dosage, solution temperature, anions (Cl 鈭?, NO 3 鈭?and F −</sup>), and heavy metal ions (Mg<sup>2+</sup> and Mn<sup>2+</sup>), were investigated, and the
Apex Engineering has designed several relatively small-scale treatment systems for sulfate removal from mine water (Table 2). The first three are packed bed systems with a continuous carbon source feed (methanol or ethanol), while the last is a passive bioreactor.
A New Process For Sulfate Removal From Industrial Waters
The CESR process is a cost-effective alternative for sulfate removal. Summary. In the Cost-Effective Sulfate Removal (CESR) process used by Hydrometrics, a proprietary reagent is added after standard lime treatment to precipitate a compound called ettringite, which can be removed using a clarifier and filter press.

Chemco-inc. Canada,Quebec, Saint-Augustin-De-Desmaures
In 1991, Chemco inaugurates its first ferric sulphate manufacturing plant in the Saint-Augustin-de-Desmaures industrial park, a suburb of the historic city of Quebec. The company then later expanded its operations to include the manufacturing of high quality aluminum sulphate and other inorganic coagulants until 2012, year of the

Abstract. The solubilisation of metals and metalloids is catalysed by a variety of microorganisms in natural and engineered environments. Biosolubilisation has a number of undesired implications, such as the generation of acid mine drainage and the formation of acid sulfate soils, which have harmful environmental impacts.
Direct Biological Conversion of Electrical Current into
New sustainable methods are needed to produce renewable energy carriers that can be stored and used for transportation, heating, or chemical production. Here we demonstrate that methane can directly be produced using a biocathode containing methanogens in electrochemical systems (abiotic anode) or microbial electrolysis cells (MECs; biotic anode) by a process called electromethanogenesis. At a
before the urban wastewater treatment directive is fully implemented. Progress so far has been achieved through capital investments and advanced forms of treatment. Future trends show that further reductions in wastewater pollution will be achieved especially in the EU-10 Member States, supported by the EU structural and cohesion funds from 2007.
