Environmental safety evaluation from galvanic sludge during long-term storage

Tretiakova Larissa, Mitiuk Ludmila

Journal of New Technologies in Environmental Science

2020

Vol. 4, nr 3

105--113

The article analyses the ecological state of the soil in an enterprise with a galvanic shop that produces chips and microcircuits. The problem of production waste storage in open areas is investigated. Environmental hazards during long-term storage of sludge have been identified. The composition of the sludge obtained after sewage treatment of the production of the copper line was investigated. A method for predicting the level and depth of soil salinity during long-term sludge storage is proposed. The experience of reuse of copper extracted from sludge is analysed.

Assessment of soil salinity from galvanic sludge during s long-term storage in open areas

Tretiakova Larisa, Mitiuk Lyudmila

Journal of New Technologies in Environmental Science

2019

Vol. 3, nr 4

206--214

The article analyzes the ecological state of the soil in an enterprise with a galvanic shop that produces chips and microcircuits. The problem of production waste storage in open areas is investigated. Environmental hazards during long-term storage of sludge have been identified. The composition of the sludge obtained after sewage treatment of the production of the copper line was investigated. A method for predicting the level and depth of soil salinity during long-term sludge storage is proposed. The experience of reuse of copper extracted from sludge is analyzed. Maximum service life of packaging made of polyvinyl chloride to save the sludge was determined.

Reagent Technology of Joint Purification of Sewage Water for Paint and Galvanic Production

Hurynovich A., Maroz U.

Journal of Ecological Engineering

2018

Vol. 19, nr 6

208--216

There is a need to create a low-cost and effective resource-saving technology for wastewater treatment contaminated with paintwork materials, which would allow reusing water in the production cycle of the enterprise. Studies have been carried out to prove the possibility of using spent technological solutions in the joint purification of sewage from galvanic and paint and varnish industries. The developed technology enables to reduce the costs of the enterprises for its cleaning and negative impact on the environment, reduce the load on urban treatment facilities, and reduce the equipment costs.
