The evaluation included following: (1) characteristic determination; (2) selection at lab scale, establishing operating conditions process efficiency; (3) scaling up level; (4) plant design commercial availability analysis required equipment; (5) costs inversion operation treatment, cost/m3 recovery, time investment recovery. physicochemical...

The aim of this study was to evaluate the effectiveness chitosan–tomato plant extract (C-TPE) edible coating (EC) on physicochemical, microbiological, sensory, and antioxidant capacity changes pork during storage. Edible coatings prepared with chitosan 1%, acetic acid glycerol, TPE (0.1% 0.3%) were tested. Slices submerged in different treatments (T1: C 1%; T2: 1% + 0.1%; T3: 0.3%; T4: control) stored at 4 °C. showed best results physicochemical microbiological analyses, reduced microbial...

This study investigates the corrosion resistance of chitosan and its crosslinked form coatings applied on stainless steel as substrate using various analytical techniques. Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), energy-dispersive X-ray (EDS) were employed for surface characterization. Electrochemical impedance (EIS) potentiodynamic polarization (PDP) techniques used to analyze electrochemical behavior. Four evaluated along with naked (ss):...

Reverse osmosis (RO) desalination is considered a viable alternative to reduce water scarcity; however, its energy consumption high. Photovoltaic (PV) in processes has gained popularity recent years. The temperature identified as variable that directly affects the behavior of different parameters RO process and production PV panels. objective this study was evaluate effect on polarization factor at 20, 23, 26 30 °C. Tests were conducted plant driven by fixed 24-module system received spray...

This research paper presents a review of the state art desalination in Mexico, with aim clarifying main challenges and opportunity areas for as solution to overcome water stress. First, current situation forecasts on availability resources Mexico are described, followed by economic, social, legislative issues desalination. Mexico’s installed capacity different technologies their evolution recent years was investigated, comparison global trends. The development carried out Mexican...

Water is a necessary resource for life development. Its excessive consumption has negative impact, generating scarcity problems worldwide. Desalination an alternative to solve these problems; its objective reduce the concentration of total dissolved solids levels suitable consumption. The most widely used desalination technology reverse osmosis, which works by means semipermeable membranes; however, lack knowledge or wrong operation cause phenomena such as polarization, reduces effective...

Metals are widely used in various industrial applications due to their advantageous properties, but they often exhibit signs of degradation over time because prolonged exposure environmental conditions. To prevent corrosion, coatings have gained popularity owing practicality maintaining the original shape and dimensions object being protected. Nevertheless, traditional may pose significant toxicological concerns, leading researchers explore eco-friendly alternatives such as chitosan-based...

Reverse osmosis (RO) desalination is a technology that commonly used to mitigate water scarcity problems; one of its disadvantages the bio-fouling membranes used, which reduces performance. In order minimize this problem, study prepared modified thin film composite (TFC) by incorporation chitosan-silver particles (CS-Ag) different molecular weights, and evaluated them in terms their anti-biofouling performances. The CS-Ag were obtained using ionotropic gelation, characterized Fourier...

Water scarcity slows down economical and industrial development, population growth.Desalination by reverse osmosis is a separation process used to reduce the dissolved salt content of saline water usable level offer one solution alternative this problem.The use simulators allows obtain optimal design in production energy consumption.The objective study was select operation conditions using IMSDesign simulator, provide satisfy demand Puerto Peñasco, Mexico, with projection year 2040.Data...

With each passing year, water scarcity in the world is increasing, drying up rivers, lakes, and dams. Reverse osmosis technology a very viable alternative which helps to reduce shortages. One of challenges make process more efficient, this can be achieved by improving capacity adapting membranes with nanomaterials order increase permeate flux without exceeding limits established process. In research, brackish (BW30) were modified ZnO nanoparticles interphase polymerization. The BW30...

Una alternativa para hacer frente al desabasto de agua consumo humano, industrial y agrícola, es la desalinización aguas marinas salobres.Este proceso consiste en separación sales del mediante diversas tecnologías.Sin embargo, a pesar los beneficios que ofrecen, una desventaja importante cantidad salmuera generada su impacto ambiental como resultado alta salinidad.Bajo este contexto, el objetivo estudio realizar comparación técnicas descarga vertidos salmueras producidas por planta...

Desalination allows reducing water scarcity problems by means of techniques as reverse osmosis (RO), and currently, its main disadvantage is high energy demand.Therefore, this study assessed consumption a desalination plant RO with different current concentrations (5,000-36 000 mg/L total dissolved solids), maintaining constant feed conversion flux 14.4 m 3 /d 40%.Additionally, three photovoltaic (PV) systems were used an source: fixed, single-axis, dual-axis trackers.Instantaneous power was...

The study consists of evaluating the response three hybrids castor plant (Ricinus communis L.), Zoya 856, Olga 864 and Galit K-93, to four irrigation treatments at different salt concentrations (2.3, 3.12, 3.9 4.68 dS m -1 ) simultaneously.The objective was compare yield between for each treatment, as well determine effects caused by excess in stages germination, flowering growth plant.The research conducted Block 1916 Yaqui Valley, located state Sonora, Mexico.Irrigation water obtained from...
