Natural zeolites as effective adsorbents in water
Application of natural zeolites for water and wastewater treatment has been realised and is still a promising technique in environmental cleaning processes. In the past decades, utilisation of natural zeolites has been focussed on ammonium and heavy metal removal due to the nature of ion exchange and some review papers have been appeared [6

Natural zeolites are abundant and low cost resources, which are crystalline hydrated aluminosilicates with a framework structure containing pores occupied by water, alkali and alkaline earth cations. Due to their high cation-exchange ability as well as to the molecular sieve properties, natural zeolites have been widely used as adsorbents in separation and purification processes in the past...
Zeolite in Nuclear Remediation Cleanup and Spills The
Natural Zeolites have superior selectivity for certain radionuclides compared with organoresins. Zeolites are also a better value and are much more resistant to nuclear degradation. The decontamination of radioactive waste solutions is mainly based on the use of Zeolite as a cation exchanger.
The aim of this work is a synthesis of previously published data on the behaviour of natural (and some synthetic) zeolites at high pressure, in order to understand: (1) the relationship between compressibility and microporosity; (2) the framework flexibility, through deformation mechanisms at the atomistic level and (3) the different roles played by framework (i.e. Si/Al-ordering, different

Technical Reports Series No. - IAEA
treatment of spent ion exchange media has been covered in two IAEA Technical Reports, one published in 1967 (Technical Reports Series No. 78, Operation and Control of Ion-exchange Processes for Treatment of Radioactive Wastes), the other in 1985 (Technical Reports Series No. 254, Treatment of Spent Ion-exchange Resins for Storage and Disposal).
In the USA and Great Britain zeolite are routinely applied for the decontamination of radioactive wastewater to remove Cs and Sr radioisotopes. However, these are small-scale operations compared to the extensive use of natural zeolites at Chernobyl disaster in 1986.
Vacuum evaporators for wastewater minimization
Introduction to vacuum evaporators. Vacuum evaporators, also know as wastewater evaporators, are one of the most effective technologies for the minimization and treatment of industrial wastewater. The technology is clean, safe, very versatile and has a very low management cost. In many cases, it can also lead to a treatment system with zero discharge.
The water salts are termed Dissolved Solids, and as such will require technologies that change the state of the water salts from dissolved to insolvable and thereby removable. Below are some examples of the types of systems which Condorchem Envitech can work with the client to ensure that the correct cost effective solution is found.
- Are polyaluminum chloride products FDA approved?
- Polyaluminum chloride products used in the treatment of potable (drinking) water must be approved by the National Sanitation Foundation (NSF). Aluminum chlorohydrate for topical use as an antiperspirant is regulated by the FDA. (This is an excellent review of the literature on this chemistry.)
- What are the properties of aluminium poly chloride?
- stics : Olygomer, Aluminium Poly Chloride Compound. Solubility : Highly soluble, miscible in all proportion Melting Point : -Freezing Point : (-)10 degree C Flash Point : Non Flammable Ignition Temperature : Not Applicable Explosive Properties : Not Applicable Partition coefficient (Water)
- What is fengbai poly aluminum chloride?
- Description: Poly aluminium chloride (PAC) , the white or yellow powder, is an inorganic polymer coagulant. Compared with traditional inorganic coagulants, fengbai poly aluminum chloride flocculation precipitation speed is fast, the PH value applicable range is wide, water purification effect is obvious and non-corrosive to pipeline equipment.
- What is poly Aluminium chloride used for?
- Poly aluminium chloride uses in paper industry. In addition to water treatment applications, poly-aluminium chloride can also be used in the recycled paper industry. It plays a major role in the paper industry as a filter, which can improve the purity of paper. 3. Cosmetics industry.
