Organic polyelectrolytes in water treatment. Several methods have been used to treat such wastewaters, including ion exchange, filtration, flotation, flocculation, and solvent extraction
engineering, production and sale of equipment for civil and industrial sludge dewatering. With about 50 employees, the company is situated in the hinterland of Milan, a modern factory having a total area of 5.000 m². 2.500 m² are used for production and storehouse, while 500 m² are reserved for the
Optimisation of some wastewaters treatment using
The paper presents a new laboratory study of some heavy metals ions separation (e.g.: Cu2+, Ni2+, Zn2+, Pb2+) together with the pine oil, using a combined procedure: chemical precipitation
The authors establish correlations between certain physicochemical properties of polyelectrolytes and their flocculating activity in the treatment of refinery and petrochemical wastewater containing petroleum crudes and products. The polyelectrolytes tested include poly-1,2-dimethyl-5-vinyl

The present invention provides methods of treating or clarifying a turbid wastewater containing at least one contaminant selected from the group consisting of proteinaceous materials, fats, oils, and other biological contaminants. The methods of the present invention include the steps of (a) contacting turbid wastewater to cellulose ester fibrets under conditions sufficient to flocculate the ...
A comprehensive review on harvesting of microalgae
Harvesting is a process by which algal biomass is separated from the medium using various techniques. Separation of cells from the dilute microalgal suspension makes harvesting more expensive than harvesting the terrestrial counterparts .High harvesting costs are owing to the tiny veritable cell size (3–30 µm) in much-diluted cultures (inferior biomass concentration < 0.6 g L −1) which is

AbstractRecently, removal of nickel ions has been gaining a lot of attention because of the negative impact of nickel ions on the environment. The aim of this review paper is to organize the scattered available information on removal of nickel ions from aqueous solutions through the adsorption process. Survey on investigated materials suggests that composite- and polymer-based adsorbents have
The growth of membrane technology - ScienceDirect
Not all journal articles come out of the same mold. This one is a hybrid. It has some of the elements of a review. But any comprehensive review of the membrane technology field written today would have to contain even more references than this one does.
Biosolids are mherently odorous and if handled improperly can create offensive odors and other pollutants and nuisances which may cost a lot of time and money to con-ect. Control of odors is one of the most difficult problems in biosolids treatment and management. It is especially true if biosolids are beneficially used.
- What is ecologix enhanced DAF?
- The Ecologix Enhanced DAF is a complete primary (phys/chem) treatment system. It is an incredibly versatile and efficient chemical precipitation and physical separation system. The E-DAF combines several proven technologies such as DAF (Dissolved Air Flotation) and DGF (Dissolved Gas Flotation), into a single platform.
- Why should you choose a DAF design for process water & wastewater treatment?
- For process water and wastewater treatment, achieve high solids capture rate in advanced, compact DAF designs. Meet strict industry standards and facilitate compliance to environmental regulations.
- How does a DAF system work?
- DAF systems are designed to remove total suspended solids (TSS), biochemical oxygen demand (BOD), and oils and greases (O&G) from a wastewater stream. Contaminants are removed using a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.
- Why did World Water Works choose MBBR -> DAF?
- World Water Works, Inc. was awarded the design and supply of the above-listed technologies for two main reasons. The DAF (Dissolved Air Flotation) technology, following the MBBR (Moving Bed Biofilm Reactor) process, was demonstrated to be the most robust, forgiving, and consistent technology of the many that were evaluated.
