Geocache Description:

Slepnis novietots pie notekudenu biologiskas attirisanas stacijas "Daugavdriva" duunju kraatuveem, kas izbuvetas uz Sleeperu purva.
Aktiva darbiba sheit vairs nenotiek, tapec nekada apsardze netrauces tur mierigi staigat.
Konteiners nav redzams! UZMANIBU!!! Lai arii citiem buutu interesanti, luudzu, novietojiet konteineru un visu paareejo tieshi kaa bija!

Biologiskaa nokeudenju attirishanas stacija tika izbuveta, lai gan mehaniski, gan biologiski attiritu SIA Rigas udens turp novaditos sadzives notekudenjus.
"Daugavgriva" savu darbibu uzsaka 1991. gada. Tas projekteta jauda ir 350 tukstoši m³ diennakti.
Attirišanas process "Daugavgriva" sakas ar notekudens izplušanu caur vairakiem mehaniskas attirišanas režgiem. Savaktais piesanojums nonak savakšanas tvertnes. Lai atdalitu smiltis, izmanto horizontalos smilškerajus. Izgulsnetas smiltis tiek savaktas tvertnes. Notekudnu mehanisko attirišanu pabeidz radialajos nostadinašanas baseinos, kuru kopejais tilpums ir 24 000 m³.
Pec notekudnu mehaniskas attirišanas tiek veikta biologiska attirišana, izmantojot pasaules prakse plaši lietoto tehnologiju -gan mehanisko, gan biologisko attirišanu (anaerobo -anoksisko -aerobo attirišanu). Notekudni sakuma ieplust anaerobaja zona, kura tiek sajaukti ar aktivam dnam un noteiktu laiku iztureti. Talak notekudni pariet uz anoksisko zonu, kur ari tiek iztureti. Pec šis zonas notekudni parplust aerobaja zona, kura intensivi tiek padots skabeklis un notekudni tiek sajaukti ar aktivam dunam. Tad biologiski attirito notekudeni nostadina otrejos baseinos.
Pec attirišanas udeni izvada Rigas juras lici -aptuveni 2,4 km attaluma no krasta linijas un 15 m dziluma.
