“…Among the five different industries, wastewater of dyeing industry contains higher pH values 9.0 and wastewater of leather industry contains higher EC and TDS values of 4307 µS cm -1 and 5209 mg L -1 , respectively. The use of sodium carbonate and salt in the dyeing process and electrolytes in the bleaching process causes an increase in EC of the wastewater (Mountassir et al, 2013). Kamal et al (2015) who found almost similar pH value (9.7) like this study in dyeing industry.…”

This study was conducted to assess the quality of different industrial wastewater. Some physicochemical parameters viz., pH, EC, TDS, Na+, K+, Ca++, Mg++, CO32-, HCO3-, Cl-, SO42-, PO43- including heavy metal contents like Pb, Cd, Ni, Cr, As, Zn and Cu concentration from collected wastewater samples were analyzed. Atomic Absorption Spectrophotometer was used for analyzing the heavy metals in the wastewater samples. The results revealed that, the values of pH, EC, TDS ranged between 6.44-9.0, 471-4307 ?S cm-1, 1952-5209 mg L-1, respectively. The higher mean concentrations of Na+, K+, Ca++, Mg++, CO3-, HCO3-, Cl-, SO42-, PO43- were 1407.8, 27.9, 69.9, 76.6, 2.7, 11.7, 1688, 76.6, 6.1 mg L-1, respectively. The mean concentration of Cd, Ni, Cr, Zn, and Cu was 0.17, 0.87, 85.73, 0.80, and 1.56 mg L-1, respectively. Among trace elements Ni and Cd, Zn and Cd, Zn and Cr showed a positive relationship. To avoid the harmful effects of wastewater on environment it is imperative to treat industrial effluents before discharge into open environment.J. Environ. Sci. & Natural Resources, 9(2): 21-25 2016

“…The samples for microbial analysis were analyzed within 24 h after sampling while those for the heavy metals were preserved in a refrigerator maintained at 4°C after being acidified with nitric acid to lower pH to a value of less than 2 (Mountassir et al 2013).…”

This study was carried out to determine the heavy metals and microbial loads of raw public toilet sludge from low income areas (peri-urban and rural) of Ashanti Region of Ghana. Fecal sludges were sampled from public toilets. Methods outlined in Standard Methods for the Examination of Water and Wastewaters were used for the analyses of fecal sludge samples. Range of heavy metals concentrations were found as 0.039-5.216 mg/l and 0.010-1.488 mg/l for peri-urban and rural areas, respectively. These concentrations were in the order of Mn . .Cu . .Fe . .Zn . .Pb . .Ar . .Cd and Zn . .Mn . .Fe . .Cu . .Pb . .Ar . .Cd for peri-urban and rural areas, respectively. The range of bacteria loads was measured as 1.4 Â 10 6 -4.5 Â 10 7 CFU/100 ml for peri-urban and 0.2 Â 10 6 -4.5 Â 10 7 CFU/100 ml for rural areas. Similarly, range of helminths was determined as 1-18 eggs/100 ml for both peri-urban and rural areas. The study showed that the levels of heavy metals and microbial quantities were generally higher in peri-urban compared to rural areas. However, fecal sludge from these low income areas are not recommended for direct use in agriculture unless they are given further treatment. Composting is recommended as a promising and suitable method for effective treatment of fecal sludge resulting in a hygienically safe and economically profitable product.

“…According to Mountassir et al, 2013, Kacha et al, 1997, this wastewater is also characterized by high pH, high temperature, and organic load as well as extreme colors. These carcinogenic and mutagenic pollutants (Sandra et al, 2000) are resistant to biodegradation and possess a potential for inhibiting microbial activity.…”

Textile industry represents an important source of toxic substances rejected in environment. Indeed, effluent of these industries contains dyes and chemicals. They are rejected in environment without any treatment. The aim of this work is to evaluate ecotoxicological effect of industrial textile effluents on the sludge harvested from activated sludge treatment plant of Marrakech city (Morocco). For this, we are interested in determining the inhibition condition that corresponds to 50% decrease of bacterial activity in sludge. Obtained results showed that inhibition percentage of bacterial activity depends narrowly on contact time and on added effluent volume, until a limit concentration where there is no degradation of substratum. In fact, substratum degradation speed shows about 65 times decrease when 80% (v/v) of textile wastewater is added, in comparison with the controlled one. Consequently the inhibition constant (Ki) that corresponds to 50% of bacterial inhibition activity is estimated to 0.65 mg l−1 of dye. These studies confirm a real ecotoxicological risk of these effluents. Therefore, a treatment is mandatory before their rejection in environment.
