Technological and Constructive Proposals on Sand Trap and Removal from Industrial and Domestic Waste Water

Abstract:

Abstract: The studies on operating effectiveness of sand traps in partially acting facilities of the Yerevan Aeration Plant have shown that along the satisfactory clarification of silts (sand) of mineral origin at the facility bed materials of organic origin are also trapped causing sand traps failure their main function which is clearly separation of the two types of waste waters. In addition serious problems and difficulties arise also in the sand removal. Therefore, in this paper it is suggested both technological ( grounded reduction of the number of sand traps and including in the mechanical unit clarification plants equipped with bioflocculation chambers) and constructive (by substantially decreasing the length of sand traps) solutions. It also is suggested for the first time to apply a new technology designed to remove the sand from sand traps both in the above aeration plant and new industrial and domestic waste water clarification plants under engineering design.
