COVER LAGOON DESING & CONSTRUCTION

VWG Engineering has developed a tropical lagoon digester  for the treatment  of wastewater with high organic content and organic solids. These systems are designed and constructed with expert engineering knowledge and are highly efficient. 

Our expertise has helped us to create a tropicalized covered lagoon system  which is very  efficient, economical and  can be constructed by  local companies. 

Our digester  are CSTR systems  with mechanical  agitation and or Circulation pump  to improve biogas production and avoid the formation of scum and foam. Through the agitation will be also improved  the biogas production and a better degradation of COD.

We install in all our digester a pumping system to extract the sludge which  sediment at the bottom of the lagoon.

On this way, we do prevent that after a few years of operation the digester will be filled with sludge. 

Blankets of scum may form during a startup or after a few years of operation. During startup a thin zone of high volatile acid content may become localized at the digester surface. Under a mature system a thick, black layer of grease, vegetable matter, and concentrated  sludge may cover the entire surface.

Under a mature system the breakdown of scum at the surface of the digester may cause foaming. When scum degrades, a pocket of high volatile acid content develops. The acids produce a condition that is similar to startup. Stratification of non-digested solids near the surface causes foaming.

If foam and scum production in an anaerobic digester is a severe and frequent problem that we have solve in our covered lagoon digester through the instalation of  agitators.
