Sewage Plant, Japanese Style

Atami City needed a new sewage treatment plant. But, as in all of Japan, land is scarce. And as a sightseeing spot and hot spring resort, Atami City wanted neither to mar its natural beauty nor to pollute its air. So, the city decided to build an underground sewage treatment plant topped with a hotel and amusement complex. The plant occupies 2.5 acres and has a 9.5 million gallons per day maximum treatment capacity. Plant efluent is discharged through an outfall line into the ocean and does not harm the bathing area. The exhaust, deodorized with ozone, 108 is discharged from atop the cliff. Bulletin, Welsbach Corp.

protection, and as a dual-purpose cleaner and rust preventive in singlestage washers with water or solvent. S. C. Johnson & Son, lnc. 89

Inductance alarm unit. A fact sheet on an inductance-type alarm unit is available. The unit is for use in an alarm instrument case to open or close an electrical circuit at a preset value of the measured process variable. Two types of alarm functions are possible: adjustable differential type where a relay changes

state when process variable passes through a differential switching band; and acceptable zone-type where a relay changes state while process variable is in the differential band. Fischer & Porter Co. 90

Modular automation system. A 4-page bulletin covers a modular automation system for control of critical variables that cause scale or corrosion in recirculating cooling water equipment. Four modules are available: inhibitor, conVolume 1, Number 2, February 1967 173
