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 (...

This paper presents results of investigations on physicochemical treatment of vegetable oil refinery wastewater (VORW), namely acid and technological wastewater. The study has shown that VORW has a varying high pollution load (organic matter, sulfates, phosphates and chlorides) and the removal of these pollutants from acid wastewater was more effective than that from technological wastewater; t...

The Anzali Ramsar Convention wetland is located in an ecologically and economically important region in Iran. The wetland is largely surrounded by agriculture, natural forests and rangelands (approximately 36% and 63%, respectively). Urban areas consist of less than 1% of the total area. Urban land use produces the highest rates of nutrient transfer into the lake as TN, TP and BOD5 equal to 24,...

Data on this paper show the concentrations of COD, BOD5, TSS, K+, Ca2+, Na+, Cl-, [Formula: see text], [Formula: see text], Mn2+, Fe2+, Mg2+, Zn2+, Ni, Pb, Cu and Cd in the influent and effluent of wastewater, and also the nematode eggs, total and fecal coliform in effluents from wastewater treatment plant of Rasht, Guilan Province, in Iran. Measurements of pollutants in influent and effluent w...

Urbanization has been found to impact stormwater runoff quantity and quality. A study catchment with mixed land use, residential and industrial were investigated and the water quality discharged from the catchment were sampled and tested for four basic water quality parameters; BOD5, NH3-N, NO3-N and P. One dry weather flow and several stormwater runoff were sampled. Results were compared to th...

Biotechnology involves the provision of services to society by microbial communities. By using microorganisms detoxify contaminated water, one such service offers environmentally friendly solutions treatment wastewater. Isolates fungi Aspergillus niger, Candida albicans and microalgal isolates Tetradesmus nygaardi Scenedesmus quadricauda were efficiently utilized for The wastewater sample was t...
