Dissolved Matter

The concentrations of suspended particles were measured in the drinking water of two distribution systems, and the nature of these particles documented. The concentrations of particulate matter were invariably found to be small (maximum 350 μg/L). They are globally in the very low range in comparison with dissolved matter concentrations, which are measured in several hundreds of mg/L. Except during special water quality events, such as turnover of the raw water resource, results show that organic matter represents the most important fraction of suspended solids (from 40 to 76%) in treated and distributed water. Examination of the nature of the particles made it possible to develop several hypotheses about the type of particles penetrating Montreal's distribution system during the turnover period (algae skeleton, clays). These particles were found to have been transported throughout the distribution systems quite easily, and this could result in the accumulation of deposits if their surface charge were ever even slightly destabilised, or if the particles were to penetrate the laminar flow areas that are fairly typical of remote locations in distribution systems.

The objective of the present investigation was a high level of purification of the wastewater from an oil refinery achieved by using some improved methods yielding an effluent suitable for recycling into the process. All the investigations were carried out on a continuous laboratory pilot system consisting of the following units: dissolved air flotation (DAF), sedimentation, double-stage microbiological reactor, and adsorption columns filled with granular biologically activated carbon (GBAC). A high degree of COD reduction close to 100% (precisely, 99.95 %), as well as removal of nitrogen compounds of 72% was achieved during a relatively short retention time within the range of 15-16.5 hrs. The DAF technique combined with gravitational separation was used to achieve the recovery of free oil matter up to 98%, without any preliminary conditioning. After the sedimentation of coagulated and flocculated dispersed oils, the microbiological oxidation of dissolved matter was accomplished by using two kinds of activated sludge for easy and hard degradable organics. Using the continuously bioregenerating GBAC, an effluent having a lowered COD value to about 9 was obtained. At the same time, the denitrification process took place. According to the obtained results the treated oil refinery wastewater can be recycled into the process, or discharged into a water recipient of a low self-purifying capacity.

Waste Degradation

Banyuurip landfill generates leachate containing suspended and dissolved matter, including some heavy metals, a result of waste degradation and decomposition of organic materials. Leachate can infiltrate the soil then contaminate groundwater. Once the leachate infiltration reaches the soil and groundwater, it will contaminate the surrounding environment. In this study, the contamination of leachate into ground water was investigated by measuring the concentration of Manganese (Mn), Iron (Fe) and Free Ammonia (NH3-N) in leachate and dug wells surrounding the landfill. The concentration of Mn, Fe and NH3-N in leachate was found to be 5.42 mg/L, 6.16 mg/L, and 1652 mg/L, respectively. The concentration in the surrounding dug wells located within 500 m from the landfill varied from 0.00 – 0.86 mg/L for free ammonia, 0.00 – 0.31 mg/L for total Fe, and 0.00 – 0.26 mg/L for total Mn. The concentration of Mn, Fe and NH3-N decrease with increasing distance between the landfill and wells.

Reproductive ability of cyanobacteriums are one of main parameters of ecological conditions of water-basin and it is especially actually for artificial water objects. Changes of concentrations of blue-green algae in warm year period allows to trace zones of strong pollution without additional attraction of chemical laboratory. Thus it is enough significant mean have prognosis of situation evolution with use cyanobacteriums. With this aim it was received equation of change concentration of blue-green algae in dependence of time in taking to account different degree content of dissolved matter, and possible temperature stratification for considered water objects by different weather condition. On accordance of calculated data by predictable weather and temperature conditions of summer season it is possible to estimate consequences of pollutions by blue-green algae, and to make recommendations for improvement this situation. At prediction of possible ecological disaster it is offered to use innovative method of elimination the consequences, based on hydro-mechanical filtration. As nozzle for pollution catching it is argued the necessity of use milled cane, which source is exceed in shallow water. It should be note, that this type filter can not only retard different fine impurities and blue-green algae, but absorb ions of heavy metals. Moreover, nozzle’s filler is exposed by ecological safety utilization. Replaceable cartridges with milled cane is able to additionally clean coastline from rough water flora and to direct in consequence all biomass to units of biogas production.
