Chromium, Atomic Number 24, Atomic Weight 51.996 is a metallic element in Group VIb of the Periodic Table of the Elements. The name "chromium" is derived from the Greek for "Color" probably because many salts of chromium are highly colored. Chromium naturally occurs in rocks, animals, plants, soil and in volcanic dust and gases.
The educational and research laboratories (area 750 m2) include a range of pilot plants and laboratory-scale experimental facilities for water treatment techniques such as sand filtration, membrane filtration, ozonation, coagulation and flotation, and aerobic and anaerobic purification processes.
The presence of heavy metals (Zn, Cr, Pb, Cd, Cu, Mn, Fe, etc.) in wastewater is a serious environmental problem and their removal by natural zeolites have been extensively studied along with other technologies, including chemical precipitation, ion exchange, adsorption, membrane filtration, coagulation flocculation, flotation and ...

Coagulation is a process that removes the impurities (especially suspended particles and colloids) in water by destabilizing and agglomerating the particles into larger aggregates.
The system investigated has an alkaline pH and is composed of a mixture of hydrophylic compounds. This means that the flocculation process is the consequence of the precipitation of Al(OH) 3 and Fe(OH) 3 in colloidal form and the adsorption of the organic components present .Flocculation of nascent Al(OH) 3 by anions follows the Schulze–Hardy rule, which describes the relationship between ...

Lenntech Water Treatment solutions is a design and manufacturing company serving numerous industries. Since 1993, we've been delivering innovative and sustainable solutions for several applications and processes of water treatment, wastewater reuse and membrane separation.
carried out using atomic absorption spectrophotometer (Philips 9100X, England). Coagulation Process: The conventional 'Jar test' procedure, was employed for coagulation, flocculation and sedimentation processes. The coagulant used is ferric chloride, while the coagulant aid (polymer) is a non – ionic polyacrylamide. The
The Coagulation Analyzer is a netlized blood analyzing and inspecting instrument. It can be used to diagnose the disease of bleeding and thrombus, also used in the clinic diagnosing such as inspecting and curative effect watching the disease of thrombus dissolving and blood coagulating treatment.
Laboratory Filtration laboratory Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. The fluid that passes through is called the filtrate Diagram of simple filtration: oversize particles in thefeed cannot pass through the lattice structure of the ...

Batch tests were performed to study this process. Solids were removed by membrane filtration. Metal residuals were analyzed by atomic absorption spectrophotometry. Chromium was rapidly and stoichiometrically reduced by ferrous sulfate.
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical ...

Coagulation as a pre-treatment can be done with or without sedimentation (known also inline coagulation). Without sedimentation, the whole system will be compact in size. However, coagulation–sedimentation systems generally produce better feed quality to membrane filtration, .
Filtration is technically defined as the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of a membrane, called a filter. Filtration Examples. The most common example is making tea. While preparing tea, a filter or a sieve is used to separate tea leaves from the water. Through the sieve ...
