Have been studied kinetic, equilibrium, and dynamic conditions for adsorption of tetracycline hydrochloride from aqueous solutions on two samples of industrial activated carbons SKT and BAU-A. It has been determined that the kinetic data of adsorption can be approximated with sufficient accuracy by the Glückauf equation. To calculate tetracycline hydrochloride’s equilibrium adsorption, it has been proposed to use the Dubinin-Radushkevich equation, and to calculate the adsorption duration — the Dubinin-Nikolaev equation. The possibility for practical application of activated carbons for wastewater treatment from antibiotics has been demonstrated, and ways for increasing of these carbons’ adsorption activity have been proposed.

Abstract Wastewater from car wash stations of agricultural machinery is contaminated with mechanical impurities, oil products, pollution generated by exhaust gases, fertilizers and processing agents used in agriculture, as well as a large amount of surfactants. Purification of this wastewater to the quality required for their reuse allows organizing a circulating water supply scheme, which significantly reduces not only the negative impact on the environment, but also the need for clean tap water. This article describes the results of wastewater treatment from car wash stations of agricultural machinery on an electroflotator and post-treatment by filtration through various filter media, incl. through a sorbent made of modified rice straw - agricultural waste.

Study Results

This research aims to produce activated carbon from bamboo waste (used bamboo chopsticks), activated by low-cost and non-toxic chemical substance (Sodium Chloride, NaCl), as an option for silk dyeing wastewater treatment in a small cottage industry. Initially, used bamboo chopsticks were carbonization at 600 °C to produce bamboo charcoal. Then the charcoal was activated using three different methods: (a) soaking in the NaCl solution at the charcoal to NaCl (weight/weight) ratio of 1:1; (b) burning at 800 °C; and (c) activating using the previously mentioned 2 methods together by soaking in the NaCl solution at the ratio of 1:1 then burning at 800 °C. The activated carbons physical characteristics study has found that the activated carbon activated using the third method had the highest BET specific surface area of 327.69 m2/g, total specific pore volume of 0.18 mg/l, and average pore size of 22.52 Å. The adsorption study of the activated carbon activated by NaCl and temperature used synthetic wastewater of red acid dye (AR114) with the initial concentrations of 20 mg/l. The study results have showed that the activated carbon activated by NaCl and temperature reached equilibrium within 180 minutes, and had the color removal efficiency of 77.36%. The adsorption isotherm study results have indicated that the acid dye adsorption of the activated carbon activated by NaCl and temperature followed the Langmuir isotherm.
