Low-Cost Pre-Treatment of Pharmaceutical Wastewater
Pharmaceutical industries and effluents of sewage treatment plants are the main sources of residual pharmaceuticals in water resources. These emergent pollutants may adversely impact the biophysical environment. Pharmaceutical industries often generate wastewater that changes in characteristics and quantity depending on the used manufacturing processes. Carbamazepine (CBZ), {5Hdibenzo [b,f]azep...
متن کاملCost-effective Treatment Technology on Textile Industrial Wastewater in Bangladesh
To minimize the cost effective treatment process a treatment process has been setup at Dalas Fashion Ltd and Liz Fashion Ltd, Gazipur, Dhaka. The treatment process consisted of a combined process (anaerobic and bio-filtration process) to remove the pollution through biological process. The anaerobic process followed by Up-flow Anaerobic Sludge Blanket (UASB) process and Bio-filtration was maint...
متن کاملParticulate-biofilm, expanded-bed technology for high-rate, low-cost wastewater treatment: nitrification.
The performance of a particulate-biofilm, expanded-bed process for nitrification of activated sludge final effluent (ASFE) is reported for a plant receiving mixed industrial and domestic wastewater. The support material for the particulate-biofilms was glassy coke, to which the nitrifying bacteria attached and formed a highly active biofilm. An average nitrification rate of 1.7+/-0.6 kg m(expan...
متن کاملLow Cost Wastewater Treatment and Potentials for Re-use A Cleaner Production Approach to Wastewater Management
Current mainstream technologies for wastewater treatment, such as activated sludge and tertiary nutrient removal are too costly to provide a satisfactory solution for the increasing wastewater problems in developing regions. Besides, these technologies do not allow for re-use of valuable energy and nutrients contained in the wastewater. This paper introduces a so called ‘Cleaner Production’ con...
متن کاملLow Cost Technologies for Water Treatment and Wastewater Collection and Treatment
In many developing countries like India and Thailand and also developed countries like USA and Holland many studies were conducted, concerning slow sand filters as a means for water treatment that has many advantages that suit the abilities of these countries either economically or technically. These studies indicate that slow sand filters are markedly affected by the climatic conditions and th...
