The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate in a batch mode with aeration and sludge settlement both occurring in the same tank. Difference between SBR and activated sludge system is that the SBR ta...
Silt Density Index (SDI)
A standardized test that measures the particulate and colloidal fouling potential of feed water for reverse osmosis and nanofiltration systems, defined by ASTM D4189. The Silt Density Index, or SDI, measures the particulate and colloidal fo...
Sludge Solids Handling Packages
Sludge conditioning is a process whereby sludge solids are treated with chemicals or various other means to prepare the sludge for dewatering processes Chemical Conditioning: Chemical conditioning (sludge conditioning) prepares the sludge ...
Sludge Thickening
Wastewater treatment plants commonly use thickening devices to increase the solids concentration at the end of a particular process step within the activated sludge process. Thickening of sludge increases its solids content and reduces the ...
Softening Plants
Water Softening Plants: A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water. These “hardness ions” cause three major kinds of undesired effects....
Storage Silos
Storage silos are cylindrical shape structures with the slip and straight form. Concrete silos are the larger in terms of diameter and height . Silos could be made of many materials. Wood , concrete , cast concrete, and steel Plates , glass...
Suspended Solids Treatment
Bag Filters and Accessories: Suspended solids and other fine particles can be removed from liquid streams by passing them through filters. Bag filters are a convenient and economical choice for applications that require gross particulate re...
Tail Element Scaling
The deposition of mineral scale on the final elements of a reverse osmosis pressure vessel, where the concentration of rejected ions is at its highest and crossflow velocity is at its lowest. Tail element scaling is the deposition of minera...
Tertiary Filtration
The purpose of tertiary treatment is to provide a final treatment stage to raise the effluent quality before it is discharged to the receiving environment (sea, river, lake, ground, etc.). More than one tertiary treatment process may be use...
Thermal Drying Systems
Thermal Drying of Wastewater Solids : Thermal drying is one of the technologies available for processing of solids produced at municipal wastewater treatment plants (WWTPs). Thermal drying technology, although originally developed for mate...
