Opis:
Water pollution has increased due to human activities; consequently, it is essential to treat both surface water and ground water so they are suitable to meet the needs of the population. This study will discuss water treatment intended to remove antimony. Antimony (Sb) is classed as a high-priority toxic pollutant because of its adverse effects on ecosystems and human health. There are several methods for removing antimony from water, including adsorption, coagulation, ion exchange, and electrochemical treatment. This study focuses on the adsorption method as researchers have, in recent times, been seeking adsorbents that are environmentally friendly and cost-effective and that do not leave a residue. The study investigates the use of orange peels treated with acetic acid as an adsorbent to remove antimony ions from a simulated aqueous solution. The results revealed that 5 g of treated orange peels is 98.5% effective at treating water at a pH of 6, for a contact time of 150 minutes, at a mixing speed of 450 rpm.

Opis:
Wastewater from the confectionery industry is characterized by daily and seasonal variability of composition and quantity which adversely affects the process of their disposal. Confectionery plants discharge about 300-500 m3 per month of technological wastewater. Sewage from the confectionery industry belongs to biologically degradable. It is characterized by high values of chemical oxygen demand (COD) and biological oxygen demand (BOD). The article reviews various methods used to treat wastewater from the confectionery industry. Attention was paid to the applicability of a particular method, its advantages and disadvantages and the costs of implementation. The technology of industrial wastewater treatment uses both mechanical and physicochemical methods as well as biological ones. Techniques of sewage treatment usually consist of several stages which use different processes. Low-cost materials such as natural minerals, agricultural waste, industrial waste, biosorbents, and others contribute to the improvement of aerobic sewage conditions. The main weakness of typical sewage treatment plants is their large area, high investment, and exploitation costs. Therefore, a good solution may be the use of the membrane biological reactor which combines the classical technique of activated sludge and filtration on micro-filtering membranes.
