The examinations concerned determination of the treatment efficiency of wastewater form dairy industry using the system which combines methane fermentation with ultrafiltration process. The study attempted to determine the effect of HRT and OLR on the degree of biodegradation of contaminants contained in the sludge examined and on the quality and amount of biogas. The anaerobic process obtained a considerable degree of the removal of organic pollutants from raw wastewater designated as COD (73.8%), BOD (81.2%) and TOC (76%). The concentrations of COD and BOD were 1053 mg/dm3 and 329 mg/dm3, respectively. The value of TOC reached a level of 288 mg/dm3. Generated biogas in the methane fermentation process of wastewater from dairy wastewater was characterized by high methane content (82 % vol.). In the final part of the experiment, the UF process was used in order to posttreating effluent from UASB reactor. During the UF process, COD, BOD and TOC parameters were removed at 72%, 63% and 67%, respectively.

Aim. Development of a complex of detergents (acidic, alkaline, enzymatic, chlorine-containing, surfactant-containing additives) for membrane units used in the dairy industry. Materials and Methods. Methods for controlling the concentration of active substances in concentrates of agents are given on the example of KATELON 202 - determination of total acidity by the method of acid-base potentiometric titration (in terms of HNO3) and KATELON 114 – determination of the mass fraction of active chlorine by redox titration. Results. A complex of detergents for membrane plants (ultrafiltration (UV, UF), microfiltration (MF, MF), nanofiltration (NF, NF), reverse osmosis (RO, RO)), used in the dairy industry and including alkaline non-foaming, medium-, low-foam products KATELON 109, KATELON 110, KATELON 115; alkaline chlorine-containing non-foamy agent KATELON 114; acid non-foamy KATELON 202, KATELON 207, KATELON 208; high-foam neutral additives KATELON 308 and KATELON 309 – enhancers of the washing effect for KATELON 109, KATELON 110, KATELON 115; preservative non-foaming additive KATELON 310 for protection from microbiological contamination; enzyme medium supplement KATELON 601. The composition of all products, their brief characteristics and physicochemical indicators, as well as an approximate program of washing with a complex of developed preparations are given. The dependences of pH and electrical conductivity were obtained for KATELON 109, KATELON 110, KATELON 115, KATELON 202, KATELON 207, KATELON 208. Conclusion. The complex of detergents is successfully used at Kopylsky Butter Cheese Plant, Lyubansky Cheese Making Plant, Minsk Dairy Plant No. 1, Verkhnedvinsky Butter and Cheese Plant, Molodechno Dairy Plant, Volozhin production site of Minsk Dairy Plant No. 1, Tolochin Branch of Lepel Dairy Canning Plant.

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Sn 1987A

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

The Future

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).
