Abstract In recent days, the waste productions from industries are increased and direct discharge of wastes causes various pollution to environment. Wastewater treatment in textile dye industry mainly involves highly colored wastewater containing variety dyes different concentrations. The dyeing using types pigments concentration during their several production steps. These a which contains org...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

A laboratory-scale pilot plant of moving bed biofilm reactor coupled with membrane bioreactor (MBBR-MBR) was studied regard to wastewater treatment in the textile industry, and reuse feasibility treated water investigated. The comprised two connected parts: an aerobic tank filled carriers a submerged tank. MBBR-MBR system reduced hydraulic retention time 1 day, which is very promising compared ...

In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

Nghiên cứu nhằm đánh giá hiệu quả xử lý nước thải sinh hoạt bể phản ứng thể di động (Moving bed biofilm reactor - MBBR) kết hợp với cột màng lọc tự chế ở những thời gian lưu khác nhau. Bể MBBR có tích 45,54 L chứa 40% K3, và quy mô phòng thí nghiệm được sử dụng trong nghiên cứu. Kết cho thấy tải nạp vào là 0,47 kg BOD5/m3/ngày, 0,79 m3/m2/ngày qua màng, 6 giờ, đầu ra đã đạt QCVN 14:2008/BTNMT (...

Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...
