A study of the movements of Wedge-tailed Shearwaters Puffinus pacificus in Sydney coastal waters was carried out over the six years 1968-73 inclusive. The birds, normally considered sedentary, gradually departed during April and were completely absent during winter. The first birds usually returned about 20 August with the bulk of the population arriving soon afterwards. Arrival dates at Coffs Harbour, 450 kilometres north, appear to be up to two weeks earlier. Evidence from banding and beach-washed birds supports the conclusion that pacificus is absent in winter. The significance of three recoveries of birds banded in New South Wales in the Philippines is discussed. The status of pacificus in Queensland and Western Australia is reviewed briefly and a historical record documented.

The relative success of chemical oxygen demand (COD) removal models to describe measured rates of COD removal in a pilot-scale constructed wetland designed for treatment of high-strength winery wastewater are evaluated using retention times determined from tracer studies. Not surprisingly, two-parameter residual and retardation models better fit the measured removal data than single-parameter, first-order decay models for wastewater at average COD loadings up to nearly 5000 mg/L. The residual and retardation models yielded nearly equivalent fits to the measured data. However, the retardation model had more consistent parameters for COD removal data across different depth levels in the constructed wetland and at different loadings, and a slightly smaller sum of least-squared errors. The retardation model seems to be appropriate for constructed wetland design because it allows a steady decrease in COD with increased treatment time rather than a constant residual COD (C*) value. From the least-squares optimization procedure used to estimate model parameters (a volumetric rate constant, Kv, range of 3 to 12 d(-1)), nonrealistic, or physically meaningless, large C* values (C* range of 23 to 450 mg COD/L) that were dependent on COD loading were obtained, potentially underestimating the constructed wetland system's actual winery wastewater treatment potential. The optimal parameters for the retardation model applied to the pilot-scale constructed wetland ranged from 9 to 12 d(-1) for the initial degradation rate constant, Ko, and 2 to 5 d(-1) for the time-based retardation coefficient, b. These values should be verified for full-scale field systems based on field measurements currently underway.

This article describes two basic improvements in the filtering of photographic chemicals in large-scale applications. The first is a new filter vessel construction using a recently developed high-strength composite material called tensioned fiber reinforced plastic (TFRP). This eliminates the corrosive effects of photographic chemicals and reduces the pressure drop normally associated with metallic filter vessels used in high-pressure, high-temperature applications. The second is a cartridge with extended surface area and fixed pore size. The extended surface area increases the useful cartridge life, decreases the pressure drop, and improves filtrate quality over commonly used polyspun and string-wound cartridges.
