The Behavior of Suspended Solids, Dissolved Solids and Dissolved Organic Carbon in Freezing and Thawing Process for Excess Activated Sludge.

Effects of suspended solids and dissolved organic carbon on nickel toxicity.

Nickel (Ni) is a common and potentially toxic heavy metal in many fluvial ecosystems. We examined the potentially competitive and complementary roles of suspended sediment and a dissolved organic ligand, humate, in affecting the partitioning and toxicity of Ni to a model organism, Daphnia magna, in both batch and stream-recirculating flume (SRF) tests. Sediments included a fine-grained deposit,...

Feasibility Study of Reducing the Total Dissolved Solids (TDS) from Contaminated Water in Radish Plant (Raphanus Sativus) Using Nano Activated Carbon and Zeolite

Applying Nanoporous Materials is an appropriate method for improving chemical quality of the water due to high surface area, internal porous structure (porosity), high absorption capability of harmful gases and liquids, and capability of reactivating the surface. Therefore, actions were carried out in order to investigate the effect of Activated carbon and Zeolite on reducing the total dissolve...

Microbial Characterization of Activated Sludge Mixed Liquor Suspended Solids

Removal of Coliform, Suspended Solids, UV254 and Colour Using Zeolite and Activated Carbon in Riverbank Filtration System

River bank filtratio filtration (RBF) is one of the novel water abstraction alternatives to tackle poor water quality problem in Malaysia. This study was conducted to investigate the potential use of zeolite and activated carbon as filter media in the laboratory RBF system. Characteristics of the materials were first determined using the surface analyzer and X-ray fluorescence method. Filter co...

Comparison in reduction of solids, turbidity and EC between nanofiltration membrane bioreactor and activated sludge

Hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. Removing them into environment without any treatment may cause serious problems for the public health. Membrane Biological Reactor is the combination of the activated sludge and membrane filters. This research has investigated the performance of the Nano-Filtration i...
