“…These ionic species originated mostly from industrial and mining processes. Relevant processes include electroplating, metal finishing, metallurgical work, tanning, chemical manufacturing, and battery manufacturing [3,4]. Due to their non-biodegradability, they tend to accumulate in the vital organs of living organisms causing various diseases and long-term disorders, as well as deleterious ecological effects [5].…”

A B S T R A C TThe removal of aqueous hexavalent chromium (Cr(VI)) by green walnut shell (GWS) was investigated in batch experiments. GWS is a readily available and low-cost horticulture solid waste. The efficiency of this biomass for Cr(VI) removal as impacted by various operational parameters was characterized. Tested parameters are: initial solution pH (pH 0 ), initial GWS mass loading ([GWS] (g L − 1 )), contact time (t (min)), GWS particle size (d (μm)), initial Cr(VI) concentration ([Cr(VI)] 0 (mg L − 1 )), and ionic strength (I(M)). Results revealed that Cr(VI) chemical reduction (to Cr(III)) followed by adsorption or surface precipitation is the removal mechanism. The optimal operational conditions for Cr(VI) removal from 50 mL of a [Cr(VI)] 0 = 10 mg L −1 solution were: pH 0 = 3.6, t = 5 min, [GWS] = 6 g L −1 , and I = 0.1 M. The corresponding removal efficiency was 95%. The kinetic of the reaction was also studied. Results indicate that using GWS is an affordable, efficient, and applicable method for aqueous Cr(VI) removal and thus a low-cost material for water treatment.

Heavy metals contents in surrounding water were relatively decreased from September to November, which was mainly due to relative decrease of temperature, salinity and other environmental factors.…”

“…Many times, concentrations of heavy metals have been observed exceeding the recommended limits of FAO/ WHO. Also, the metal concentrations exceeding the permissible limits in the aquatic environment would also become detrimental to fish health and subsequently health risk for local population consuming contaminated fish (Wasi et al, 2013).…”

This study assesses the long-term sustainability for operation and maintenance (O&M) of sewage-fed aquaculture-based sewage treatment system. The study focused on the integrated assessment of an engineered pond system of 8 million liters per day capacity in the city of Karnal, the State of Haryana, northern India. Major areas during the assessment included health, environmental, societal and institutional views aspects as well as the quality of treated effluent subjected for reuse. The treatment facility met the Indian regulatory standards (downstream reuse and discharge into the legally permitted water bodies) in terms of physical-chemical parameters. The total coliform and faecal coliform removal were up to 2-3 log units; nevertheless, it was not capable to come across the bacterial count requirement (<1,000 per 100 mL to minimise human health risk in aquaculture practices). The system was able to generate sufficient net income required for routine O&M. Annual revenue collected by the Municipal Corporation from the lease of the facility as well as selling of treated wastewater was $3,077 and $16,667-$25,000, respectively. The additional benefit from the facility for the farmers included the saving of fertilizers and cheapest source of water available for irrigation. Recycling of treated sewages for irrigation is also returned nutrients to the surrounding farms in Karnal. This exercise has saved significant quantities of chemical fertilizer (26-41 Ton of nitrogen, 10-18 Ton of phosphorous and 38-58 Ton of potassium per year) and the overall benefit for farmers during cultivation of one acre of crop was calculated to be approximately $133 per year.
