  • Dissolved and colloidal organic nitrogen removal from wastewater treatment plants effluents and reject waters using physical–chemical processes

    Four physical–chemical processes were compared in terms of the efficiencies of dissolved and colloidal organic nitrogen (DON and CON) removal from the secondary effluents (SE) and reject water from full-scale biological nutrient removal activated sludge systems. Adsorption on activated carbon was most efficient and allowed removal from the SE of up to 80% and 100% of DON and ...

  • Treatment of dye solution containing colored index acid yellow 36 by electrocoagulation using iron electrodes

    Abstract The removal of pollutants from effluents by electrocoagulation has become an attractive method in recent years. This paper deals with the batch removal of the reactive textile dye Colored Index (C. I.). Acid yellow 36 from an aqueous medium by the electrocoagulation method using iron electrodes. The effects of electrolyte concentration, initial pH, current density, electrode area, ...

  • Effect of coagulant basicity on virus removal from water by polyferric chloride

    We investigated the effect of coagulant basicity on bacteriophage removal from river water by polyferric chloride (PFC). PFC at three basicities (basicity 0.9–2.1) was prepared by means of base titration (NaOH was added to ferric chloride (FeCl3) solution) and the virus removal efficiencies of those PFCs were compared with that of FeCl3 (basicity 0). The virus removal efficiencies of the ...

  • Sorption of high explosives to water-dispersible clay: Influence of organic carbon, aluminosilicate clay, and extractable iron

    Explosives in soils can present environmental problems for military installations. Fine, mobile particles represent the most reactive fraction of the soil and, therefore, are expected to adsorb explosives and potentially facilitate their transport. The objective of this study was to determine the relative significance of phyllosilicate clay, organic matter, and two forms of extractable iron in ...

  • Treament of Hydrogen Sulfide (H2s)

    This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Waste Minimisation Strategy: Monroe Australia

     The company has implemented a major waste minimisation strategy that has enabled it to process liquid waste, reduce water usage, reduce chemical and waste disposal costs, and eliminate pollution. It installed new equipment which treats wastewater to remove emulsified fats and oils, grease, heavy metals and all forms of suspended, colloidal and some dissolved solids. Mains water usage has ...


  • Common Boiler Feed Water Treatment Issues and How to Avoid Them

    When treating boiler feed water (the combination of boiler makeup and condensate return water), several issues can arise that cause boiler scaling, corrosion, fouling, and system failure. Below, we break down the most common boiler feed water issues and how to avoid them to help ensure system efficiency and operational safety. While treating boiler feed water is extremely ...

  • Victor Project – De Beers Canada, Ontario case study

    In early 2006 De Beers Canada began the construction of its first Ontario diamond mine, in the James Bay Lowlands. To provide drinking water for this mining camp and its daily workforce of nearly 1,000 , the engineering- consulting firm AMEC recommended that De Beers Canada call on the expertise of H2O Innovation. H2O presented a solution that matched its client's very special needs and ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • What is a wastewater treatment system and how does it work?

    For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoid harming the environment, human health, and a facility’s process or products (especially if the wastewater ...

  • Softener Plant Supplier in Chennai, Chennai

    Water is and will be the primal focus as the world evolves every day. We might be surrounded by large water masses, but those still need to be effectively utilized. Water, today is available in different formats or to be more modern, in different Avatars. The key question is how much can be made effective for human consumption. The resolution lies in treatment of water fit enough for consumption ...

  • In-depth analysis of changes restores system optimization - Case Study

    Introduction A reverse osmosis plant (BWRO) had been operating effectively applying Avista antiscalant and cleaners for about a year. Increased product water demand led to changes in the feed water quality and an increase in plant recovery resulting in an increase in stress on the pre-treatment system and more rapid membrane fouling. The existing membrane cleaning regime was reviewed to try ...
