Pressure sewerage system: the principles of pressure sewer
Pressure sewer system is recognized by the recent worldwide unique system of drainage waste water is used both in civil and in the construction industry.
Advantages of pressure sewer (as compared with the laying of gravity sewers): The system pressure sewer main site are not cumbersome treatment plants, requiring large overhead costs for their quality service, and one or more pumping stations. Low cost and timing of construction works. The minimum volume of the developed soil at laying pressure pipe (about two meters above the ground). Cutting mechanism allows the pump to pump effluent to the mass of plastic pipes with small diameters (80 mm) without the risk of clogging. Increased durability. The principle of pressure sewer Sewage sent to the collection of one or more houses, then pumped through a special pump equipped with a cutting device - Flowing into existing drains or directly into the sewer operating system. At the same pipeline network pressure sewer is designed so that each of the pumps could transport the pumped liquid in place of the end of the discharge line, even without the need for further pumping. Discharge pressure sewer pipe with a diameter of 40 mm or more is designed so that at a certain timing pump flow rate of water was about 0,7 m / sec. At this rate starts to operate so-called self-cleaning effect of sewer pipes. Scope of application of pressure sewer otkanalizirovanie civil engineering; otkanalizirovanie emerging industrial zones; otkanalizirovanie industrial sites and businesses.
