STUDIES CONCERNING THE BEHAVIOR OF THE SUSPENDED SOLIDS IN THE MIXING PROCESS

A high importance is given to the studies concerning the most reliable mixing process with a minimum of energy consumption, because the mixing process is an often used operation in various industries. The main purpose of this paper is to determine and to identify the behavior of the dispersed phase, in this case, the solid particle, during the mixing process. Through the experiment, the mixing process was recorded using a High-Speed camera, which enables following the behavior of the solid particle. The resulting data were used for different types of charts

THE PRODUCTION CAPACITY OF LEACHATE COLECTED FROM PIATRA NEAMT LANDFILL

Lately it was seen an growth and range broadening of activities in all sectors of economy and society and therefore, the management of waste is a problem facing the entire planet. This paper purpose an analysis of a Romanian Landfill, concerning leachate production. Mathematical models applied on landfill products create an environmental background in which concerns waste management in Romania

EXPLOITATION OF ORGANIC ULTRAFILTRATION MEMBRANES IN THE REMOVAL OF PEPTONE FROM WASTEWATER

In the present paper an ultrafiltration experiment was carried out for testing the polyacrylonitrile (PAN) membrane in the process of peptone separation from wastewater. The evaluation of the applied ultrafiltration process consisted in the monitoring and the recording of the parameters as well as of some indicators that will reveal the PAN membrane efficiency (the percentage of peptone retention on the membrane surface, the volume and quality of the resulting permeate in the pre-established time period). The obtained results showed that the peptone retention efficiency was noticeably, around 20 % and the obtained permeate volume did not decrease greatly, only by 2.5 L over 300 minutes experiment

PRODUCTION CAPACITY OF LEACHATE FROM BIHOR LANDFILL

Landfilling is one of the most important issues that can be discussed nowadays related to waste management, mainly concerning the importance of what we have to do with waste quantities and how energy can be recovered. The paper proposes a threedimensional mathematical model applied to calculate the production capacity of leachate from Bihor landfill, situated in Bihor County, Romania. The leachate production capacity is related to the total amount of waste disposed in landfill during active phase. The parameters taken into consideration in the research refer only to the municipal solid waste quantity disposed and the life of the landfill. Leachate production time was divided into two well-defined periods: active phase, in which the waste was stored in landfill and the post-closure phase – the period of time until the landfill is definitively closed (30 years). The mathematical model has been elaborated and tested using TableCurve 3D software based on data provided by SC EcoBihor SA and based on the assessment of leachate quantity that can be collected from the landfill. The mathematical model proposed offers a viable solution to determine the maximum leachate production capacity during municipal solid waste landfilling
