Wastewater treatment currently exists a wide variety of
ways such as chemical process [1], biological process [2],
physical process [3]-[4] bio-chemical process [5], bio-physical
process [6]-[8] physico-chemical process [9]-[11] and
combined process [12] depending on whether it is appropriate
to choose any method of wastewater treatment. Considering
the nature of the waste water can be considered from the
condition of the area, as well as performance and the budget
must be worthwhile and the most economical. Water
containing organic material should be used for the treatment of
biological waste water containing organic biological
decomposition. Wastewater treatment by EM ball is a method
of biological wastewater treatment. The EM ball is the
effectiveness microorganisms are capable of degrading
organic matter. This is effective in the treatment of waste
water from the building community and general establishment.
If the microorganism in EM ball can treat wastewater to water
better quality, so it is the way to decrease cause of water
pollution.
