This paper describes Philippine farmers’ perception on farm mechanization and land reformation. For a survey, 280 farmers were interviewed. According to the survey, Philippine farmerrespondents seem to recognize the many advantages of using farm machines over manual, even if these are expensive and will certainly displace laborers. Although land reformation is known to only one third of the farmers, they understand it as a way of re-structuring roads and fields, and will ease farm management. Philippine farmers’ awareness of farm mechanization and land reformation appears to be very low and they also have financial problems when they consider to adopt farm mechanization and land reformation. Therefor, it is very essential to raise farmer’s awareness and also provide financial subsidy to farmers who have willingness to adopt mechanization and land reformation. Also introduction of farm land bank system like korean experience is recommended as one of alternatives.

Polytetrafluoroethylene (PTFE) membrane has high resistance to chlorine, which is a great advantages in chemical cleaning to recover water flux during membrane processes in drinking water systems. A humic kaolin water with approximately 4 mg/L of DOC and 10 NTU of turbidity was prepared as a feed water. Coagulation pretreatment with or without settling was applied. The coagulation with settling showed the greatest water production. The reduced flux was effectively recovered by NaOCl cleaning, i.e., 21% recovery by 50 mg/L of NaOCl cleaning and 49% recovery by 500 mg/L NaOCl cleaning. The images of SEM and AFM analyses were corresponded to the water flux variation. However, when the floc was accumulated on the membrane surfaces, the efficiency of NaOCl cleaning was substantially limited. In addition, dynamic contact angle became greater after cleaning, which indicates changes in characteristics of fouling layer such as surface hydrophobicity. Proper cleaning technologies during enhanced backwash using NaOCl would expand application of PTFE membranes in drinking water systems.
