The wastewater treatment plant management of community hospital, Ministry of Public Health in central region
Abstract:
This research studied the wastewater treatment system management in 30-60 bedded
community hospitals under the Ministry of Public Health, in the Central Region of
Thailand. Samples of 33 community hospitals from the provinces located along the Chao
Phraya River Basin, except those of Bangkok and Samutprakarn, were selected as
designated targets. Four different sets of questionnaires were tested for structure and
content validity by experts. Data were collected during the period April-June 2004. The
reliability value was more than 0.7. Hospital directors who were responsible for the
wastewater treatment system, public health officers or community health officials who
controlled the system, daily workers on the system, and people residing around the
hospitals were requested to answer the questionnaires. Data of analytical quality were
collected on effluent and hospital effluent samples were analyzed for water quality. The
data were analyzed using descriptive statistics and multiple stepwise regression, This look
at the association of the factors regarding administrators, controllers and daily workers of
the wastewater treatment system with wastewater quantity, B.O.D. value, and satisfaction
of administrators, operators, and people. SWOT matrix analysis of the problems and
obstacles facing management of wastewater treatment system was conducted based on
questionires and statistics. The results of this analysis were used to establish managerial
guidelines for the improvement and development of the hospital wastewater treatment
system.
The research found that wastewater treatment cost was about 24 Baht per cu.m..
People who were admitted to the hospital were willing to pay a wastewater treatment fee
of about 10 Baht per day. The generated volume of wastewater was about 40±33 cu.m. per
day, and 97% of the total wastewater was treated. The average effluent B.O.D. value was
about 20.78±14.72 mg/l. Hospital directors, controllers, workers, and people were
satisfied with the wastewater treatment performance with average values of satisfaction
being 3.5, 3.7, 3.3, and 3.6 out of 5 respectively. It was also found that the method
(techniques and practice) and sufficiency of equipment were related to the satisfaction of
the daily worker (p < 0.005), with a R2 = 0.797. In addition, guidelines in improvement
and development of wastewater treatment system performance were recommended with
an emphasis on providing seminars, supervision for the treatment plant operators, an
increase in the financial income, an effective and appropriate usage of materials, and
promotion of people’s participation in community hospital wastewater treatment.
