Oily Wastewater Treatment

Oily wastewater is one of the most dangerous forms of environmental pollution, it is large amount of water that is wasted petrochemical industries, oily waste water contains oil, suspended solids, and dissolved solids. The study investigates the treatment of real oily waste water that was collected from al-Dura refinery (Iraq) /Middle Refineries Company from oil and suspended solid contamination for re-use and environmental consideration using coagulation and flocculation processes. Coagulation /flocculation is a common method used as primary purification processes to oily wastewater treatment due to its usability, performance, and low cost. Coagulation experiments were completed by the Jar Test device. The additives coagulants of ferric sulfate and aluminum sulfate were in a range about (10- 25) ppm, as well as polyelectrolyte- (polyacrylamide) as an additional flocculent in the range (1-4) ppm. The results show that ferric sulfate was more efficient in removing turbidity than Aluminum sulfate under the same conditions, with the best removal of turbidity at dose concentration 20 ppm of Ferric sulfate and a flocculent dose concentration of 3 ppm of polyacrylamide, also with oil content decreasing from 288 ppm to 14.4 ppm and the turbidity removal from 187 to 8.5 NTU.

Fixed Bed Reactors

The Paris Metropolitan area, which contains over eight million inhabitants, has a daily output of about 3 M cu.meters of wastewater, the purification of which is achieved by SIAAP (Paris Metropolitan Area Sewage Service) in both Achères and Valenton plants. The carbon pollution is eliminated from over 2 M cu.m/day at Achères. In order to improve the quality of output water, its tertiary nitrification in fixed-bed reactors has been contemplated. The BIOFOR (Degremont) and BIOCARBONE (OTV) processes could be tested in semi-industrial pilot reactors at the CRITER research center of SIAAP. At a reference temperature of 13°C, the removed load is approximately 0.5 kg N NH4/m3.day. From a practical point of view, it may be asserted that in such operating conditions as should be at the Achères plant, one cubic meter of filter can handle the tertiary nitification of one cubic meter of purified water per hour at an effluent temperature of 13°C.

Detection Limits

In Germany the application of procedures such as flocculation and filtration in the preparation of drinking water results in the annual production of an estimated 500,000 t of sediments and sludges. Some of these residues have a potential for being reused, for example in agriculture, forestry, brickworks or waste water treatment. To assess the microbiological quality of residues from waterworks methods for the detection of enterobacteria, Escherichia coli, Salmonella, Pseudomonas aeruginosa, Legionella, poliovirus, Ascaris suis eggs and Cryptosporidium have been evaluated regarding their detection limits and were applied to various residues from German waterworks. Results show that sediments and sludges may contain pathogenic bacteria, viruses and protista. When residues from waterworks are intended to be reused in agriculture or forestry the microbiological quality should therefore be considered.

The study was conducted to evaluate the impact of training facilitated by Nuton Jibon Livelihood Improvement Project (NJLIP) under Social Development Foundation (SDF) for transfer livestock technologies and livelihood improvement for rural poor farmers in Bangladesh. A total of 650 farming households were selected by baseline survey during January 2018 to June 2018.The training and non-training beneficiaries were primary level educated and their family size (4.52) was little lower than the national average (4.9). Average age was 36.73 and 35.12 years for training and non-training farmers, respectively. The rate and amount of loan was found higher with respondent received training than without training. Adoption rate of technologies was higher than the level of idea on the concept of housing, feeding, breeding and marketing. The training beneficiaries improved knowledge and skill on feeding, management and health care of livestock and poultry. Training and demonstration are considered two strong tools for adoption and dissemination of livestock technology. Herd and flock size was increased by training beneficiaries than non-training beneficiaries. Beneficiaries having training on various IGAs have expanded their land and asset possession to a greater extent compared to non-training beneficiaries. Housing and sanitation condition of training beneficiaries were higher than non-training beneficiaries. Increased annual income of training and non-training households was 19.43% and 13.30% where income from different IGAs of livestock was 32.19% and 14.53%, respectively. Livestock were not extremely price sensitive but more sensitive on non-price factors logistic support like institutional support, quality of input and availability of input. Thus, training was treated as vital tools for transfer livestock technologies to influence the poor farmer’s livelihood improvement of training household than non-training household. SAARC J.

The trans-boundary area between the Europe Union and other countries is highly susceptible to changes in water quality and variations in the potential pollution load that could influence its eco-systems significantly. The Neris (Viliya) River is one of the biggest surface water bodies in Lithuania and Belarus with an ecologically important area protected by international legislation. The study was aimed at evaluating the impacts of integrated pollution on water quality of the Neris River taking into account different storm-water flows and ecological scenarios. For this purpose, qualitative and quantitative statistical evaluation was set up and calculation was done; different integrated pollution loads of the catchment area were estimated. The evaluation considered a decrease in river discharge due to changes in the regional storm-water flow and technological development that should lead to the growing covered surface and a reduction in the untreated storm-water flows. The obtained results indicated that, in the case of storm-water treatment, the total nitrate and phosphate concentrations will decrease, while in the cases of changes in combined suspended solid, the concentration of nutrients will decrease. Thus, a trans-boundary storm-water treatment plant of the Viliya River is required as it should eliminate pollution accumulation and restore its acceptable environmental status. A coordinated international project for the entire catchment of the Neris (Viliya) River based on the specifications and requirements of the EU Water Framework Directive (EU 2000) should be developed and implemented. Subsequently, ecological river-use policies should be established at the international level, which should offer considerable perspectives for the sustainable development of the area.
