Effect of the dosage of flocculants on sludge dewatering is analyzed through the determination of sludge specific resistance to filtration. Sludge dewatering behaviors conditioned on Polymeric aluminum, PAM, fly ash and composite flocculants have been compared. The results show all the conditioning agent have help to sludge dewatering. Fly ash from electric power plant as conditioning agent can greatly reduce the specific resistance of sludge and the dewatering performance can be improved.The optimal dosage of fine powdered coal is 20g/100mL and coarse powdered coal is 30g/100mL.Powdered coal is mixed with sludge to form filter cake which is blended with coal in certain proportion to make into fuel.

On the area involved in the influence of conteminations emitted by the aluminium works and electric power plant, the degree of atmospheric air pollution was evaluated on the basis of the behaviour of healthy thallus of the lichen <i>Parmelia physodes</i>, analysis of fluorine and sulphur content in this thallus and in the bark substrate and the F and SO<sub>2</sub> concentrations in the air.

In this study several types of bricks were produced containing substituent from industrial wastes. The industrial wastes used are palm oil and electric power plant fly ash. These waste products are used to replace the natural ingredient in the manufacturing of brick clay namely as clay. Conventional bricks are produced from clay with high temperature kiln firing or from ordinary Portland cement (OPC) concrete. At the present, the world's natural resources are decreasing so many alternative actively pursued to ensure that the natural ingredients will remain unchanged for the use of the more significant and worthwhile. In this study, some suggestions have been proposed where the using of fly ash as a clay replacement materials in the percentage of 20%, 40% and 60%. The several laboratory experiments was carried out, where the high compressive strength with 20% of fly ash replacement is 15.5 N/mm2 while for the 20% of power plant fly ash replacement provide a compressive strength of 103 N/mm2. For optimum water absorption, the rate is 17.05% which is from 20% of palm oil fly ash replacement while for brick from 60% power plant fly ash, the rate of water absorption is 4.96%. Therefore, this study can contribute to recycling the industrial waste material as a replacement material in brick in Malaysia. Recycling waste is one way to ensure that waste management can be controlled.

In order to ensure the safety of the population around objects and industries that are sources of impact on the environment and human health, a special territory is established with a special regime of use - the sanitary protection zone (SPZ). According to the regulatory framework of Russia, the approximate size of the SPZ should be justified by the project of a sanitary protection zone with calculations of expected air pollution and levels of physical impact on atmospheric air, and confirmed by the results of field studies and measurements. This paper analyzes the requirements and possibilities for establishing the boundaries of the SPZ for a state regional electric power plant (SREPP). The paper presents an example of the established SPZ boundaries of the energy company, where all calculated indicators correspond to sanitary and construction norms and rules, and the company does not need to create a new SPZ project. The new requirements for defining the SPZ boundaries from 2018 are presented, and terms of object outline, areal object and circuit are analyzed.
