Kif tagħżel impjant tat-trattament tad-drenaġġ ro u kif tuża impjant tat-trattament tad-drenaġġ ro?

L-AKTAR TIPI KOMUNI TA' IMPJANTI TAT-TRATTAMENT TAD-DRENAĠĠ RO HUMA:

PROĊESS TA' ĦAMA ATTIVAT

Is-sistemi tal-proċess tal-ħama attivat (ASP) jużaw l-elettriku biex jonfħu l-arja f'drenaġġ mhux ipproċessat u mhux mittiefes. Dan ikisser is-solidi biex jiżviluppa 'soppa' bijoloġika. L-arjazzjoni tippermetti lill-batterji li jseħħu b'mod naturali fl-iskart jiddiġerixxu kwalunkwe kontenut organiku, u b'hekk inaqqsu l-livell ġenerali ta' sustanzi niġġiesa. L-impjanti tat-trattament tad-drenaġġ ASP m'għandhomx kamra tas-saldu primarja, li tfisser tbattil inqas frekwenti u inqas irwejjaħ mhux mixtieqa.

Once the sewage has been aerated for long enough, excess liquid is discharged into a clarification chamber, where live bacteria settle to the bottom. Dead bacteria rise to the top, leaving clean water in the middle – which can then be discharged safely into either a watercourse, drainage field or soakaway.

FILTRI TA' TIRWIĦ MGĦADDSA
In a submerged aeration filter, a primary settlement chamber holds solid material. This is where anaerobic digestion by bacteria takes place. Clarified water then passes into a second chamber containing a submerged media – and here, the water is treated to remove dissolved constituents by aerobic bacteria, supported by diffused air. This process ensures that full treatment is achieved before the material flows to a final settlement chamber. The final, treated wastewater is discharged to the drainage field, watercourse or soakaway.
