These article summaries the results of studying sorption equilibrium ions close to their concentration in liquid industrial waste. For experimental research, solutions with Со2+ and Cd2+ range 1·10-3–1·10-4 N have been used. concentrations match ion con¬cen¬tration waste mentioned. In experiments, Na+- modified forms natural sorbents based on clinoptilolite from Aydag deposit bentonite Dash-Sal...

The aim of this study was to determine the effect of natural zeolite (commercial preparation with 80% of clinoptilolite) on counts of different physiological groups of bacteria i.e. sulfide-producing, faecal and total coliform, mesophilic aerobic and anaerobic, and thermophilic bacteria in pig slurry. Zeolite was spread daily directly over partially slatted floor in a dose of 0.4 kg/1 m 2 durin...

Excess chemical and natural fertilizer could create eutrophication of surface waters then depletion the quality water. The present study aimed to survey removal efficiency ammonia from aqueous solution using modified clinoptilolite air stripping process optimization variables by response methodology. Clinoptilolite was obtained Semnan (Northeast Iran) with sodium chloride (to an adsorbent unifo...

This study was performed to evaluate the effects of adding different levels natural zeolite (clinoptilolite) juvenile rainbow trout (Onchorynchus mykiss) diets about growth performance and some biochemical blood parameters. The experimental system designed as a semi-recirculating aquaculture 20 trouts which weigh 7.91±0.03 g distributed randomly for each tank (300 L). Fish were fed apparent sat...

Anaerobic Membrane Bioreactor technology has great advantages for treating wastewater, including energy recovery from organic matter. However, when the legislation requires that effluent standards be met in sensitive areas, this treatment cannot remove nutrients, thus permeate generated needs post-treatment. Apart biological processes, ion exchange is an alternative stream since it can nutrient...

In this research, the utilization of zeolite (clinoptilolite) and leonardite mix, which are natural adsorbents that can be used to provide optimum water conditions for aquaculture, was investigated. Three groups with 3 replications were formed a commercial aquarium fish feed having 47.5% crude protein added as ammonia factor in three different concentrations (0.2 g feed/500 ml tap water, 0.4 g/...

Flotation using cationic surfactants has been investigated as a rapid separation technique to dewater clinoptilolite ion exchange resins, for the decontamination of radioactive cesium ions (Cs+) from nuclear waste effluent. Initial kinetic and equilibrium adsorption studies cesium, suggested large surface area volume ratio fine zeolite contributed fast kinetics high capacities (qc = 158.3 mg/g)...
