An Integrated Innovative Technology for The Treatment of Municipal Solid Waste Landfill Leachate

Abstract

The paper proposes an integrated innovative technology for the treatment of municipal solid waste landfill leachate, containing organic impurities resistant to oxidation and other toxic compounds. The developed process flow chart combines an advanced membrane technology with efficient developments of conventional wastewater treatment methods. In view of the complex multicomponent composition of municipal solid waste landfill leachate, it is proposed to use a modular approach to creating a process flow chart, which makes it possible to develop a leachate treatment technology for a specific MSW landfill, having the leachate with a specific qualitative composition. The development of this technology will make it possible to obtain purified water with characteristics, complying with the maximum allowable concentrations (MACs) for fishery water bodies.

Natural minerals impact on physical and chemical parameters of potable water

“…To purify heavily polluted water to reach the regulatory requirements, modern complex multi-stage water treatment technologies based on ultra-and nanofiltration, reverse osmosis, ion exchange, evaporation, electrochemical treatment methods, ultraviolet radiation, etc. are applied [1][2][3][4]. These water treatment technologies are complex and very expensive.…”

Aeration for increasing the bioactivators efficiency in treating household wastewater containing synthetic detergents

“…Thus, the degree of biological purification intensity of household wastewater depends on the organic substances composition and concentration, on waste treatment duration, on treatment equipment and facilities design, temperature, aeration conditions, microorganisms species composition, their adaptive capacity and resilience to the toxic pollutants effects, etc. [5][6][7][8][9]. Currently, bioactivators -compositions of highly active bacteria effectively decomposing organic substances, and enzymes in wastewater such as amylase peptidase, lipase, and lactase which facilitate breakdown of proteins, fats, and carbohydrates contained in household wastewater, are actively used to intensify the household wastewater biological treatment processes.…”

Optimization of Membrane Reverse Osmosis separation for Aqueous media characterized by High mineralization

“…Hardness salts, contained in aqueous media, particularly affect scaling process on the filter elements [5][6][7]. Hardness salts, represented by the compounds of calcium, magnesium (much rarely of strontium, barium) in the form of carbonates, bicarbonates and sulfates, when scaling on the membrane element surface form insoluble crystal formations, thereby significantly reducing the membrane element performance.…”
