Study of Treatment Efficiency of Wastewater Collected from the Surface of Roads by Natural Zeolite

Abstract

One of the main tasks of raising the technical level of highways, safety and environmental performance is timely and targeted collection and removal of water from the surface of roads and subsequent cleaning of pollution. In modern technologies of water purification processes of water filtering and filtering materials occupy the dominant position. The progressive environmental degradation of water bodies requires constant updating of filter elements, which include higher technological and environmental requirements. The new generation of modern filter materials include zeolites. In order to use the sorbents for the removal of oil, they are to be hydrophobic and, at the same time, absorbing oil well. As a result of comparative evaluation of sorption purification of waste water from the surface of roads, using zeolite and gravel mixture there was determined the efficiency of using alternative materials. The introduction of new methods of treatment using natural zeolites solves the problem of raising the technical level of highways, traffic safety and environmental performance.

Ecological Aspects of Clay Sorption Materials Usage in Leather and Fur Production Technologies

“…Previous studies demonstrate [7] that the use of sorption methods is the most effective when the initial content of chromium ions is 1-1.5 g /dm 3 . Meaning that wastewater pre-treatment is recommended.…”

“…In order to prevent environmental pollution by wastewater from industrial enterprises, the most promising way to treat them is proprietary technology, which is widely used in many countries. We have accumulated the experience of natural sorbents and their modified forms usage for the treatment of wastewater from nitrogen compounds [1,2], petroleum products [3,4], and ions. The main advantages of using adsorption materials are:…”

Influence on Environmental Safety of the Drinking Water of Nitrification in Water Reservoir Being a Source of Water Supply and Filter Filling Materials in Water Treatment Facilities

“…It is known that the chemical nature of solid substrates influences the immobilization activity of microorganisms, therefore it serves as a selective factor for the concentration of certain microorganisms, and as a kinetic indicator of their activity. Natural zeolites (widespread in Ukraine, affordable low-cost minerals) are commonly applied in water treatment and water purification technologies [16]. It is known that these minerals demonstrate ion-exchange properties in relation to ammonium; they can remove it from aqueous solutions and accumulate it.…”

Use of Natural Zeolite to Improve Quality and Environmental Safety of Natural Surface Waters and Waste Surface Waters

“…The content of suspended solids and petroleum products (PP) are one of the most important indicators have influenced to the formation of surface wastewater, the nature and degree of their contamination with mineral and organic components of different origins. This type of pollutions are most important, when a technological scheme for surface runoff treatment from highways has been chosen [9].…”
