Materials for wastewater treatment and waste treatment from waste ion exchangers

Purpose: for the treatment of waste water containing organic and mineral suspended and dissolved substances; separation of cutting fluids; dehydration of sewage sludge; waste treatment

Technical specifications:

Index	Value
Consumption for wastewater treatment from suspended solids, g / l	0.01-0.3
Sorption capacity for dyes, mg / g	up to 1500
Sorption capacity for cations and anions, mmol eq / g	1.2-2.0

Benefits:

– processing of waste that is currently stored at landfills

– simple hardware design

– no additional waste treatment required

– the technology is cost effective

– the ability to fully use the received material

Form of intellectual property protection: patent 13685 RB “Method of compaction and dehydration of sewage sludge”

Development stage: the materials were tested in relation to the wastewater of enterprises of the building materials industry, knitwear factories, fiberboard production plants, instrument-making enterprises, for the separation of cutting fluids of a number of machine-building enterprises, for the treatment of wastewater sludge from wastewater treatment plants in St. Osipovichi, g. Vitebsk and Minsk aeration station. The degree of wastewater treatment using the materials obtained reaches 90-99.8% for individual substances

Technical and economic results of the implementation: the use of material obtained from the spent ion exchanger in the processes of wastewater treatment and sediment neutralization instead of synthetic flocculants provides a reduction in the cost of purchasing reagents by 2.5-3 times while maintaining the cleaning effect

Cooperation proposals: development of a set of normative and technical documentation
