“…The maximum adsorption capacity was better than that of waste shrimp shells treated with hydrochloric acid (0.38 mmol/g) [ 19 ] and the adsorbent prepared with shrimp shells, bovine cortical bones and snail shells (0.39 mmol/g) [ 20 ]. It was also superior to the MnFe 2 O 4 /CS microsphere adsorbent (0.98 mmol/g) [ 22 ].…”

“…Generally speaking, the Cu (II) adsorbed on the waste shrimp shell is almost impossible to degrade, and is easy to pollute during storage and transportation, causing severe environmental pollution [ 17 , 22 ]. The separation and recovery of Cu (II) from adsorbents to control heavy metal pollution are gradually becoming the focus of the current research [ 1 , 23 , 24 ].…”

Removing toxic heavy metal species from aqueous solutions is a point of concern in our society. In this paper, a promising biomass adsorbent, the modified waste shrimp shell (MS), for Cu (II) removal was successfully prepared using a facile and simple one-step modification, making it possible to achieve high-efficiency recycling of the waste NaOH solution as the modification agent. The outcome shows that with the continuous increase in pH, temperature and ion concentration, the adsorption effect of MS on Cu (II) can also be continuously improved. Adsorption isotherm and adsorption kinetics were fitted with the Langmuir isotherm model and the pseudo-second-order model, respectively, and the maximum adsorption capacity of Cu (II) as obtained from the Langmuir isotherm model fitting reached 1.04 mmol/g. The systematic desorption results indicated that the desorption rate of Cu (II) in the MS could reach 100% within 6 min, where HNO3 is used as the desorption agent. Moreover, experiments have proven that after five successive recycles of NaOH as a modifier, the adsorption capacity of MS on Cu (II) was efficient and stable, maintaining tendency in 0.83–0.85 mmol/g, which shows that waste NaOH solution can be used as a modification agent in the preparation of waste shrimp shell adsorbent, such as waste NaOH solution produced in industrial production, thereby making it possible to turn waste into renewable resources and providing a new way to recycle resources.

Soil infiltration systems for wastewater treatment require very low energy and maintenance. They are very efficient, cost effective, low energy consumption, as well as low construction techniques. They have been widely implemented all the world particularly for on-site, in rem worldwide due to the significant increasing and continuous withdrawn. It has been proved that soil wastewater infiltration system (SWWIS) is considering as an important on wastewater treatment in terms of efficiency and operation and maintenance. In this systems, wastewater should be treated firstly by conventional physical/chemical or biological treatment zone. In these infiltration systems the wastewaters are purified through several steps including physical adsorption, chemical reaction, and biodegradation. SWWIS's have exhibited an excellent and co decomposing of organic contaminants, as indicated by chemical oxygen demands (COD) and biochemical oxygen demand (BOD5). Meanwhile, it is efficient in removing all the microbial contaminants as well. The challenge factors are the clogging problem as well as the removal of phosphorous, and the nitrogen.
