  Pulp and paper mills consider as a major wastewater producer industries in order to cellulosic pollution and also consuming high amount of water during the process.The wastewater treatment process is complicated because these kinds of effluents contain suspended & colloidal impurities and color & odor; so using chemical coagulants via the Jar test can be an appropriate alternative to remove the contaminants. In this research, different concentrations of Alum, PAC and FeCl3 coagulants were tested to reduce the contamination load of the effluent from three important major parts of fiber wastewater producers; that, according to the results FeCl3 was reported as the best chemical coagulants which removed 61%, 74/05 % and 58% of the COD from the three mentioned parts effluent. Therefore, chemical treatment by using of an appropriate coagulant with the optimum concentration can perform an important role in reducing the effluent contamination load. Manuscript profile

  Environmental risk assessment is a further step of environmental impact assessment and analyze different aspects of risk, while understanding the Environmental impact zone, the environmental sensitivity of the area affected by special environmental values as well as analysis and risk assessment district is considered. To accomplish this study first by using of field investigation the activities which leads to risk in construction of Caspian port water front were identified and in order to extract the significant risks the specialists questioner (Delphi) was used. Finally among the identified risks, 10 environmental risks were chosen for prioritizing.After identifying the risks, indicators such as probability, severity of risk and the sensibility of the environment were selected as prioritizing criteria. AHP method and ECPRO 2000 software, for determining the risk probability, for determination the severity of risk scores and the reference texts for determining the values of sensitivity were applied. After determining the indicators, the TOPSIS software was used to risk prioritizing. The results of prioritizing studied risk showed that the highest risk is related to increased turbidity, deformation of substrate and water pollution are with weights 0.938, 0.898 and 0.662 respectively.

  The purpose of environmental impact assessment is to identify, analyse and evaluate project activities. Environmental Impact Assessment ensures the environmental concept of sustainable development by providing the necessary environmental information to determine the environmental friendliness of a proposed project. Mechanical harvesting of aquatic plants along with biological and reed harvesting in the whole area of West Wetland and opening the entrance of Chafrud River were the main activities that could be implemented in this project. Mechanical harvesting operations are performed with a Harvester machine and reed harvesting is done with a motor saw or manually. The most important activities of the project are mechanical harvesting (reed harvesting and immersion of aquatic plants floating with the Harvester machine), restoration and cleaning of waterways (Chafrud River), dewatering and rehabilitation of West Wetland, biological control and operation of wooden bridge and bird watching station. Environmental parameters, consequences and nature of the effect, impact time, magnitude of the effect and the scope of the effect were investigated and the positive and negative effects of the design were determined.
