Ammonia is a harmful organic substance for aquaculture existence coming from high-protein foods that significantly enhances the growth of white-shrimp. The cultivation rate of artificial feed production increases the water-soluble ammonia load. Unfortunately, not all regional regulations adopt the Minister of Environment Regulation to limit ammonia levels to no more than 5 mg/L. Adsorption is an alternative solution to remove or reduce ammonia levels in liquid waste bodies. This study aims to describe the efficiency of ammonia absorption as a form of environmental management towards sustainable coastal resources, especially in hatchery of vannamei’s. The points of the discussion are the technology used in the adsorbent pre-treatment strategy, laboratory scale, and field tests for the adsorption of water-soluble ammonia. Various types of adsorption materials were compared to determine the best physical and chemical properties to be used as biosorbent. Results of the review show that applying composite technology is able to absorb more ammonia compared to a single material. An important point are finding the right adsorption material and the number of times this material which can be used to adsorb ammonia material. this has an effect on the need for provision costs for waste management in the hatchery.

“…Batch adsorption studies on the produced thin film were conducted using a UV-Vis spectrophotometer (Perkin Elmer Lambda 41) at 665 nm [43]. The adsorption parameters tested included thin film mass (50 mg), contact time (30-180 min), initial dye concentrations (10-100 ppm), pH (3)(4)(5)(6)(7)(8)(9)(10)(11)(12), and temperature (25 • C, 45 • C, and 60 • C).…”

Nanocellulose shows potential as an effective natural adsorbent for removing harmful contaminants from wastewater. This paper describes the development of innovative nanocellulose thin films made of cellulose nanocrystals (CNCs), polyacrylic acid (PAA), and active carbon (AC) as adsorbent materials for absorbing azo dyes from wastewater. The CNCs were recovered from sugarcane bagasse using alkali treatment and acid hydrolysis. The composition and processing parameters of the thin films were optimized, and their adsorption capacity was determined using thermodynamic isotherms and adsorption kinetics. Adsorption characteristics such as the methylene blue (MB) dye concentration, contact time, temperature, and pH were investigated to determine how they affected adsorption. The results show that the adsorption process follows pseudo-second-order kinetics. At an adsorbent mass of 50 mg, dye concentration of 50 ppm in 50 mL, and contact period of 120 min at 25 °C, the thin film comprising 64 wt% CNC, 16 wt% PAA, and 20 wt% AC showed high dye removal efficiency (86.3%) and adsorption capacity (43.15 mg/g). The MB removal efficiency increased to 95.56% and the adsorption capacity to 47.78 mg/g when the medium’s pH was gradually increased from neutral to alkaline. The nontoxicity, low production cost, water stability, easy recovery, and high adsorption capacity of these membranes make them suitable for water treatment systems.

“…In this context, it is recognized worldwide that antibiotics are a concerning class of water contaminants, which affect human life and also the environment [ 1 , 2 , 3 , 4 , 5 ]. Although antibiotics are powerful drugs that have been used for decades in both humans and animals to treat infectious diseases, their presence was observed in tap water, which is alarming due to the toxicity brought upon aquatic organisms and the development of antibiotic-resistant bacterial strains [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ].…”

This present study describes the investigation of new promising hybrid cryogels able to retain high amounts of antibiotics, specifically penicillin G, using chitosan or chitosan–biocellulose blends along with a naturally occurring clay, i.e., kaolin. In order to evaluate and optimize the stability of cryogels, three types of chitosan were used in this study, as follows: (i) commercial chitosan; (ii) chitosan prepared in the laboratory from commercial chitin; and (iii) chitosan prepared in the laboratory from shrimp shells. Biocellulose and kaolin, previously functionalized with an organosilane, were also investigated in terms of their potential to improve the stability of cryogels during prolonged submergence under water. The organophilization and incorporation of the clay into the polymer matrix were confirmed by different characterization techniques (such as FTIR, TGA, SEM), while their stability in time underwater was investigated by swelling measurements. As final proof of their superabsorbent behavior, the cryogels were tested for antibiotic adsorption in batch experiments, in which case cryogels based on chitosan extracted from shrimp shells seem to exhibit excellent adsorption properties for penicillin G.
