process named ‘Bion’ uses a well-controlled shallow pool
for the separation of solid particles from manure in a stable
pond system. The solids will thereafter be subjected to
harvesting, drying and screening. At the end of these processes they will be vended soil amendment applications.
Lagoon treatment contributes to the recycling of biologically
active liquid by allowing the movement of effluents in a
pond. This is normally achieved by flushing the ban’s alleys.
Lagoon treatment is considered as physical process when it
deals with solids settling of manure effluents. It is also a
biological process because both anaerobic or aerobic
biodegradation take place during the treatment course.
Therefore, there are two types of lagoon treatments that can
be used for manure effluents depending on the manure
effluent type and environmental conditions: anaerobic
lagoon and aerobic lagoon (Khalil et al. 2016). Figure 5
summarizes the advantages and disadvantages of lagoon
treatment for solid settling when dealing with manure
effluent.
3 Chemical Treatment
Manure effluents can be treated chemically with the aim of
improving solids removal, eliminating pathogens, eradicating smell and protecting the public health in preventing the
spread of diseases. In the type of treatment, coagulant agents
are added to significantly increase dewatering capacity of
manure. Coagulants carry together solid particles from
manure effluents to allow a fast settling. Carrying small
