IIssues/problem in pig wastewater treatment
25
• Inadequate and inappropriate livestock waste management.
• Insufficient local biogas constructor.
• Lack of understanding how to maintain water treatment System.
• Financial issue
GGreen Agricultural City and Biogas Construction PPromotion Project (2014--2017)
Promote the development of wastewater treatment systems in livestock by subsidizing farmers for the construction of a biogaswastewater treatment system up to 700,000 baht / farm
