#CMT# #/CMT# An installation for automatic cleaning of domestic effluents originating from sanitary equipment, comprises a pipe for collecting effluents, a unit for pretreating the collected effluents comprising a pit water associated with contributions of bacteria and/or complementary pretreatment devices such as vat degreasing tank, primary filter, scrubbers, a decanting device, a screen washing system or septic tank, and a distribution station (7) integrates an evacuation pump (8) associated with piping (11), and treatment device for purifying the pretreated effluents. #CMT# : #/CMT# The installation for automatic cleaning of domestic effluents originating from sanitary equipment, comprises pipe for collecting effluents, a unit for pretreating the collected effluents comprising a pit water associated with contributions of bacteria and/or complementary pretreatment devices such as vat degreasing tank, primary filter, scrubbers, decanting device, screen washing system or septic tank, and a distribution station (7) integrates an evacuation pump (8) associated with piping (11), and treatment device for purifying the pretreated effluents. The distribution station ensures the evacuation and purification efficiency (at least 60%), and the distribution towards the downstream of the pretreated effluents. The evacuation pump/distribution station are connected to programmable clock, which causes discontinuous operation of the evacuation pump for 30 minutes to distribute maximum 80 liters of effluents towards the treatment device. The distribution station includes a waterproof pit, which has a total volume higher than 50 liters per equivalent inhabitants and/or major part associated with housing. The evacuation pump is formed during the operation to ensure a partial recycling of the pretreated effluents within the evacuation/distribution station to cause oxygenation. A total storage capacity of the effluents of at least 830 liters per equivalent inhabitants and/or 710 liters per major part is associated with housing. The installation unit includes treatment devices, which are connected in parallel to the distribution station. The evacuation pump is a recovery pump and treatment devices are natural flow device. The treatment device consists of a container comprising a module having up and down stream compartments separated by a partition. The upstream comprises integral filtration, which is made up of filter plants such as aquatic water established on a puzzolana aggregate filter bed and the down stream is composed of vertical water column. The compartments are formed to ensure a vertical natural progression siphon of the effluents at the module with a vertical circulation towards a bottom of the upstream and towards a top of the downstream. #CMT#USE : #/CMT# Used for automatic cleaning of a domestic effluents originating from sanitary equipment. #CMT#ADVANTAGE : #/CMT# The installation is easily accessible. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows the installation for automatic cleaning of a domestic effluents: 7 : Distribution station; 8 : Evacuation pump; 11 : Pipe; 12 : Programmable control unit; 13 : Probe. |
