Among various pollutants, wastewater consists of toxic or carcinogenic heavy metals such as lead (Pb), zinc (Zn), and copper (Cu). In this study, the contamination in residential (Domestic) commercial (Car-wash centre) effluents from urban area Quetta has been investigated using atomic absorption spectroscopy. The collected liquid effluent was passed through sorbents vertical flow. combined bat...

Many communities and villages around the world face serious problems with lack of sanitation especially in disposing of the wastewater-black water and grey water from the houses, or wash outs from animal rearing sheds. Across the world diverting wastewater to the surroundings or to the public spaces are not uncommon. This is responsible for contaminating drinking water sources causing health ri...

The luminol test for blood was carried out on a set of interior fittings and surfaces inside three different makes of modern motor car. The surfaces and fittings provided little interference with the test for blood, although there was some detectable chemiluminescence when the test was applied to blood-free material from a seatbelt, a boot-lining and a gear-knob. The case with which haemoglobin...

Commercial production of eggs and egg products requires the washing of eggs to remove urinary-fecal material and broken egg residue. In the case of one Ohio farming facility, 1.6 million birds produce 1.4 million eggs per day, using approximately 50 mL of wash water/egg or approximately 70,000 L per day. The aqueous waste stream was evaluated for estrogenicity to determine if potential for endo...

In this study conditions of refinement of car wash effluent from Paniz station in omidiyeh, Khuzestan by microfiltration polyvinylidene fluoride (PVDF- MFB) membrane with pore size 0.13 micrometer by taguchi method was investigated. Taguchi method has been applied to investigate the effect of various operating parameters such as feed pressure at 3 levels (0.4, 0.7 and 1.00 bars), feed Flow rate...
