sewage

One of the industries that uses large amounts of water is the food industry. Industrial, domestic managers of the production process stand out with it and enter the environment surrounded by contaminated effluents. Their main feature is the high content of dissolved organic matter and nitrogen. You can also create wall water to create aggregate-resistant colloids, which include animal and vegetable fats, proteins, starch, sugar, as well as salts, carbohydrates, dyes, thickeners, preservatives.

At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as a secondary raw material.

The study confirmed the promising application of clays mineral sorbents for wastewater purification from Chromium (III) ions. The process of chromium ions absorption from drain water by means of natural mineral sorbent glauconite in static conditions was investigated. 
The adsorption processes were adapted to the known technological schemes of sewage and polluted surface water purification from heavy metal ions. There were measured the technological aspects of water purification by using adsorption on natural dispersed sorbents.

At present, mechanical, chemical, biochemical and physicochemical methods of cleaning are developed and efficiently used to protect water bodies from sewage pollution. The methods of biochemical wastewater purification from organic contaminants with the use of activated sludge have received the highest recognition. Getting of additional nutrients (nitrogen, phosphorus, potassium) and other trophic precursors into the aquatic ecosystem directly leads to immediate biohydrogenase reaction of increase in the number and biomass of the primary producers of organic matter.

The principal scheme of briquetting the cake that allows to solve the problem of accumulation the large number of cake on the sludge sites is proposed. The scheme is simple and environmentally completed. Запропоновано принципову схему брикетування кеку, що уможливить вирішити проблему накопичення його великої кількості на мулових майданчиках. Схема є простою і екологічно завершеною.

It is investigated prospect of using of natural zeolite for purification of sewages from salts of heavy metals. It is well-proven that maintenance of heavy metals in purified sewage reply requirements of SNIP for drinking-water in Ukraine.

The article presents the research results of using different types of silicate minerals, their modified forms for sewage sorption treatment. Their physical and chemical properties, the mechanisms of action and sorption efficiency of the widespread natural minerals are characterized in this paper.

Ecological evaluation of effluents from meat enterprises shows that processing of agricultural production is accompanied by consumption of large amount of water which is saturated with organic substances and a number of biogenic elements (phosphorus and nitrogen compounds) during its industrial utilization. Effectiveness of natural sorbents klynoptylolit use for removing of such pollutants as ammonium and phosphate ions and protein fractions was theoretically substantiated and proved.
