The present review highlights the different types of nano ferrites and their surface modified composites as an alternative adsorbent in waste water treatment. In this review, recent progresses potential applications SFNPs/SFNCs for removal organic inorganic contaminants through adsorption routes are critically reviewed. There number purification techniques but is one simplest, effective economi...

Environmental regulations for dairy farms and milk-plants tend to be tightened in Asian countries, particularly in Japan, because the milk-including wastewater discharged from them causes serious regional environmental problems. For small and medium-sized dairy farms and milk plants, we propose a novel process of using ozone which has very strong oxidative power. This proposed process is differ...

A traditional sand filter for treatment of household wastewater was constructed in the fall of 2012 at Biolinja 12, Turku, Finland. Construction work was led and monitored by an authorized wastewater treatment consultant. The filter was placed on a field bordered by open ditches from all sides in order to collect excess rain and snowmelt waters. The filter was constructed and insulated from the...

Recently, wastewater treatment by photocatalytic oxidation processes with metal oxide nanomaterials and nanocomposites such as zinc oxide, titanium dioxide, zirconium dioxide, etc. using ultraviolet (UV) and visible light or even solar energy has added massive research importance. This waste removal technique using nanostructured photocatalysts is well known because of its effectiveness in disi...

A sustainable supply of pure water is a great challenge in most developing and third-world countries. Nanomaterial-based technology offers technological development for wastewater purification. Nanocatalysis hydrogenation nitroarene dye molecules hot model many research fields. Herein, we report eco-friendly facile to synthesize Ag-Au bimetallic nanocomposites. The synthesized nanocomposites ar...

This paper evaluates the financial and economic costs of reusing wastewater with reverse osmosis (R.O.) purification systems to mitigate risks near potable quality water shortages in an urban system. A distributional analysis is also undertaken identify those who bear externalities rich data set available conduct ex-post such a system operating Cyprus for several years. The levelized cost R.O. ...

The paper studies various modifications of diatomite, aiming at creating sorbents for wastewater purification from heavy metal ions. Diatomite the Akhmatovskoe deposit Penza region was considered as a raw material. processes physical and chemical modification diatomite were investigated. Adsorption isotherms constructed, quantitative characteristics adsorption copper ions on surface modified ob...

Complex formation processes of sericin compounds with Ni 2+ , Cu Zn Co salts were studied. The possibility maximum extraction was determined when wastewater is purified by the proposed method, and developed purification method recommended for amino acid wastewater. By using coagulants Al2(SO4)3•18H2O FeCl3•6H2O flocculant PAA together sorbent, concentration in 0.75 mg/l, 0.5 amount kaolin bento...
