The saltwater system at the Tigbauan Research Station of the Southeast Asian Fisheries Development Center, Aquaculture Department.
MetadataShow full item record
Constructed in 1974, the present saltwater system of the SEAFDEC/AQD Tigbauan Research Station (TRS) consists of five pumps, two sump pits, a buffer, sedimentation and filtration treatment system (BSF), an intake pipe, and a distribution system. Two pumps operate at a time, one to bring in water from the sea to the BSF and the other to pump filtered water to distribution lines. Backwashing is provided. The pumps are operated 24 hours a day. Distribution lines are made of PVC pipes which are buried to protect them from direct sunlight. For even pressure, closed loop pipe connection is employed. Preventive maintenance undertaken to ensure continuous operation includes the intake pipe, sump pits, BSF, pumps and distribution lines. Construction of a similar system is expensive and maintenance cost is high. An intake structure patterned after the Underground Dr Concept is proposed as an alternative.
