TO overcome the pollution of pig waste being discharged to nearby rivers, a Penang state assemblyman has proposed that the pig farmers adopt the feed and sewage treatment method.
Bukit Tambun assemblyman Goh Choon Aik said that the environmental issue of pig waste has become a long-standing challenge for pig farmers.
“This situation must be addressed as it affects the ecosystem when the waste flows to the river and the seas. We can use probiotics to reduce the pollution.
“The marine lives will be largely affected if there is no solution taken to address this issue.
“Hence, we need to try and improve the situation to ensure our rivers and seas can be protected from this environmental issue,” he told Buletin Mutiara during his visit to Yenher Agro-Product Sdn Bhd in Simpang Ampat recently.
During the visit, Goh was briefed by the company’s laboratory manager Wong Chee Siang, who provided a lengthy yet informative details on how the treatment solution works.
According to him, the sewage from the pig farm passes through a solid-liquid separator to minimise organic matter in the subsequent treatment.
“In the anaerobic pond, Yenbroth (mixture of anaerobic bacteria) is applied to the waste water, which can decompose the organic matter in low oxygen level.
“This process can improve the efficiency of aerobic fermentation.
“Then, the pre-treatment water will flow to the aerobic pond for further process.
“YenClean is an effective microorganism that comprises of few types of Bacillus spp, which can utilise organic matter,” he said.
Dr Tan Yi Jing, a veterinarian, who also concurred with his colleague, said that the treatment solution can be considered to be used.
“There are many benefits from this, and I hope the authorities can look into it in a detailed manner.
“Besides that, this will be a long-term solution for the unresolved problem,” he said, hoping the recommended effort could help to solve the river pollution.
Also present was the company’s managing director Cheng Mooh Tat.
