Hvordan vælger man ro rensningsanlæg, og hvordan bruges ro rensningsanlæg?

DE MEST ALMINDELIGE TYPER RO-RENSNINGSANLÆG ER:

AKTIVERET SLAMPROCES

ASP-systemer (aktiveret slamproces) bruger elektricitet til at blæse luft ind i råt, uafgjort spildevand. Dette smadrer de faste stoffer for at udvikle en biologisk 'suppe'. Luftning gør det muligt for de naturligt forekommende bakterier i affald at fordøje ethvert organisk indhold, hvilket reducerer det samlede forurenende niveau. ASP-rensningsanlæg har ikke et primært bundfældningskammer, hvilket betyder mindre hyppig tømning og færre uønskede lugte.

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.

NEDSÆNKEDE BELUFTNINGSFILTRE
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.
