“…Based on our previous experiments and confirmed by other publications, the crystallization shape of CaCO 3 scale without electrolysis is mainly rigid needleshaped calcite, which adheres on the substrate surface firmly. This is the kind of scale deposited on pipelines and results in the scaling of cooling water system [17,18]. However, the crystallization of CaCO 3 scale formed during electrolytic process is a loose fine-granular aragonite, and a large quantity of the scale is left in water.…”

Electrolysis is an effective approach to solve the issues of scaling, corrosion, and microbiological slime, which are three major problems typically associated with industrial cooling water system. To further investigate the mechanisms and performance of electrolysis, a new electrolytic prototype device was developed. There are three tasks conducted in this study:(1) to analyze the composition and structure of the scale deposit; (2) to evaluate the ability and performance in the removal of several key substances; and (3) to investigate effects of sodium chloride concentration, duration, and current density on electrolysis. Scanning electron microscopy and X-ray diffraction results show that the scale deposited on the cathode surface was a layer of loose, fine granular calcium carbonate precipitation. Under the optimal condition of 15 min of electrolysis and current density of 10.7 mA cm −2 , the removal rate of bacteria, Ca 2+ , and chemical oxygen demand is 99.99, 52.6, and 50.8%, respectively.

“…The dyeing and finishing sectors have a strong thermal component, which allows to take action to reduce waste in the current system and where major investments are acceptable, or are able to minimize the limitations of the Second Law of Thermodynamics, or allow the recovery and utilization of the heat rejected to the environment at present [13].…”

The use of biomass as energy source becomes considered again as a possibility, after a period in which practically felt in disuse, especially in industrial environments. Nowadays is becoming again an alternative, mainly due to the increasing prices of fossil fuels, especially oil and natural gas, as well as by the growing environmental and sustainability concerns, since the biomass fuel is considered neutral in terms of CO 2 emissions. The use of biomass as solid fuel presents logistic difficulties, which do not allow their straightforward dissemination in all industrial units that intend to change its fuel. However, counterbalanced by excellent results from the economical point of view, achieved due to the stability of biomass prices in Portugal, the application of biomass is envisaged in this paper as a sustainable alternative to fossil fuels for the Portuguese textile industry. Hence, a real case study is provided to discuss advances and developments in the field of biomass applications.

“…But complete removal of colour is a big challenge. Several methods like chemical oxidation [11], ultraviolet irradiation [12], ozonation [13], photochemical oxidation [14], electrochemical oxidation [15] offer possible alternative for treatment of textile effluent. Nanofiltration can be a viable alternative in this regard.…”
