Water quality of first flush runoff from 20 industrial sites

The paper describes the results of measurements from a 2 year period on a 95 hectare urban catchment in Aalborg, Denmark. The results of the rain/discharge measurements include 160 storm events corresponding to an accumulated rain depth of totally 753 mm. The water quality measurements include 15 events with time series of concentration of SS, COD, BOD, total nitrogen and total phosphorus. The quality parameters showed significant first flush effects. The paper discusses whether either the event average concentration or the accumulated event mass is the most appropriate way to characterize the quality of the outflow.

In order to investigate stormwater pollutant loads associated with different anthropic activities and the related pollutant build-up and wash-off processes, two pilot sites have been equipped in the Liguria Region (Italy) for monitoring first flush water quality in a gas station and an auto dismantler facility. TSS, COD, HCtot and heavy metals in dissolved form (Zn, Pb, Cu, Ni, Cd, Cr) have been analyzed during the monitoring campaign (started in February 2004). Stormwater flow and quality data collected in both production sites confirm that EMC values are significantly higher than those observed in an urban site. In the auto dismantler site, the EMC values for TSS, COD and HC largely exceed the standard values (EC 91/271). Contrary to urban surface runoff, scarce correlation between TSS and COD concentrations is observed in runoff from both production sites. The occurrence and nature of the pollutant load connected to first flush flows is discussed by inspection of the M(V)-curves that are provided for all monitored water quality parameters. Significant first flush phenomenon is evidenced for TSS and HC, while such clear behavior doesn't emerge for heavy metals. Hydrologic and climatic characteristics (ADWP, rainfall intensity/depth) appear to scarcely affect the build-up and wash-off processes.

Waste water from industrial sites amount to one third of total waste water discharged into Tolich river and may have serious effects on the river water quality. With the total amount of waste water of factories (Hanoi beer alcohol and beverage joint stock corporation - HABECO, Trang An JSC and Thuong Dinh industrial park) of 45000 m3/day, these factories account for more than a half of total industrial waste water released into Tolich river. The analytic results of waste water from the main factories (HABECO, Trang An JSC, Thuong Dinh industrial park, Hanoi Soap JSC, Sao Vang Rubber JSC, Tool No.1 JSC) show that the parameters of TSS, BOD5, COD, total of nitrogen, total of phosphorus are higher than the Vietnamese standards for industrial waste water QCVN 24:2009/MONRE, column B, because the factory has an effective wastewater treatment system. The heavy metals parameters of waste water from all factories without treatment: HABECO releases 1974 tons of BOD, 766 tons of TSS, 8,4 tons of phosphorus and 52,5 tons of nitrogen annually; Trang An JSC releases 64,8 tons of BOD, 48,6 tons of TSS, 0,6 tons of phosphorus, 1,6 ton of nitrogen and 25 tons of oil and grease; HASO releases 30 tons of BOD, 33 tons of TSS and 5 tons of oil and grease. Thus, if the waste water is not treated, it can lead to a very seriously pollution of Tolich river.

Buriganga River

The Buriganga River receives partially treated sewage effluent, sewage polluted surface runoff and untreated industrial effluent from Dhaka city. This study examines the present status of surface water quality of Buriganga River at different locations in Dhaka City. The values of dissolved oxygen (DO), pH, colour, total coliforms, turbidity and ammonia were always very high over the year 2011. The maximum level of DO concentration was 3.4 mg/l, which is below the acceptable limit for surface water. Results also showed that high turbidity and low colour values were found in the rainy season while low turbidity and high colour values were found in the dry season. Moreover, the values of all parameters were always high at Buri 2 (Hazaribagh) because of the proximity of industrial sites. It is important to improve the water quality of the Buriganga River by protecting it from pollution.
