The evaluation of the water quality of the Kune-Vain lagoon complex with regard to general physico-chemical and chemical parameters was the main focus of the present study. This evaluation was based on the requirement of Council Directive of 18 July 1978 on the “quality of fresh waters needing protection or improvement in order to support fish life”, [78/659/EEC] and the requirement of Council Directive of 3 November 1998 relating to the “quality of water intended for human consumption”, [98/83/EC]. Five sampling stations were selected to successfully perform the water monitoring on the Kune-Vaini lagoon complex with a frequency of every two months, from July, 2018- July, 2019. The parameters measured were temperature, pH, conductivity, salinity, DO, BOD, TDS, total hardness, Ca2+, Mg2+, Cl– and some heavy metals. The monitored lagoons have shown notable differences based on physico-chemical parameters.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Water is one of the most important natural resources which play an essential role in human life. Most of the Nigerian institutions stored water in either plastic or overhead tanks for different purposes. However, there has been a growing concern over the safety of the stored water for human consumption following reported cases of microbial occurrence in water stored in tanks. This study aimed at investigating the water quality stored in plastic tanks in Umaru Musa Yar’adua University Katsina. Water samples were collected from plastic tanks and analyzed for some physico-chemical and heavy metals parameters. The result of physico-chemical parameters obtained shows that only dissolved oxygen, biological oxygen demand and chemical oxygen demand were observed above the maximum permissible limit for drinking recommended by WHO and NSDWQ with the mean value of 55.18 mg/l, 38.86 mg/l and 38.08 mg/l respectively. While the remaining parameters such as pH, electrical conductivity, total dissolved solids, turbidity, total suspended solid, alkalinity, sulphate, nitrate, phosphate, chloride and total hardness were found within the acceptable limit. However, analyzed result of heavy metals parameters revealed that all parameters were observed within desirable limit by WHO and NSDWQ for drinking water and suggested that the quality of water stored in plastic tanks was very good. It is concluded that, the quality of water stored in plastic tanks is suitable for human consumption. It is therefore recommended that, continuous monitoring of the water should be maintain so as to ascertain the safety of the water

Reconstituted Milk

Milk and dairy products play an important role in human diet due to their high nutritional and biological value, as well as to their easy digestibility. Milk powder makes it possible to improve the seasonal character of dairy foods. As a solvent in the production of reconstituted milk, water can significantly affect the quality of the finished product. In this regard, the problem of water quality and its preparation for the production of reconstituted milk is highly relevant. The method of separate freezing allows one to reduce the number of pre-treatment stages and energy costs. The research objectives were 1) to establish the effect of separate freezing on water quality indicators, 2) to determine the solubility index of milk powder in water prepared by the method in question, 3) to definethe energy costs. The research was carried out on the basis of the Department of Heat, Ventilation, and Air Conditioning Equipment (Kemerovo State University). The study was conducted with the help of a tank crystallizer with a controlling and measuring complex for registration of temperatures at temperatures from minus 2 to minus 10 C. In defining the quality of water and reconstituted milk, the authors used standard methods for determining its organoleptic and physico-chemical parameters. The study made it possible to define the organoleptic and physico-chemical parameters of water before and after separate freezing, the solubility index of dry milk, and the quality of reconstituted milk obtained by the method. The research revealed that it is energetically more advantageous to carry out the procedure at the temperature of minus 2 C. The present paper describes the numerous advantages of the method in that it reduces: 1) the dry residue content in tap water by 8 times, 2) the overall hardness of water by 2.5 times, 3) the content of chlorides and fluorides by 1.7 and 1.9 times, respectively, 4) the solubility index of milk powder from 0.35 to 0.1 cm3. All these factors improve the quality of reconstituted milk.

Deep Boreholes

A study to examine the effect of depth and distance of the boreholes from the septic tank on physico-chemical parameters of the borehole water consumed in Dar Es Salaam, Tanzania was conducted. Samples were collected from 48 boreholes in Ilala, Kinondoni and Temeke districts and subjected to pH, B.O.D (Biological Oxygen Demand), total hardness, copper and lead analyses in relation to safety and quality levels set by WHO and TBS. Analysis by R-statistics indicated that pH and B.O.D significantly (p<0.05) decreased as the depth of borehole increased, whereas total hardness was significantly (p<0.05) higher in very deep boreholes than the other heights. Total hardness and pH were not significantly (p>0.05) affected by distance between septic tank and borehole and the B.O.D levels were significantly higher in the borehole water situated near the septic tank than those which were far. Based on the physico-chemical characteristics of water, 25% of the samples did not comply with WHO and TBS specification limits while 75% complied, most of which had shallow depths and were situated near the septic tank. It may thus be concluded that both the distance and the depth between septic tank and borehole influenced physico-chemical characteristics of water.
