This study is focused on biosorption process used in water treatment. The process has a number of advantages and a lot of research has been done into its intensification by means of ultrasonic modification of solutions. The study carried out by the authors leads to the conclusion that sonication of organic solutions allows for extension of the time of operation of carbon beds. For the analysis of the results obtained during the sorption of humic substances (HS) from the solution dependencies UV/UV0 or DOC/DOC0 were used. In comparative studies the effectiveness of sorption and sonosorption (UV/UV0) shows that the share of ultrasounds (US) is beneficial for extension of time deposit, both at a flow rate HS solution equal to 1 m/h and 5 m/h. Analysis of the US impact sorption on HS sorption in a biological fluidized bed, both prepared from biopreparat and the activated sludge confirms the higher efficiency compared to sonobiosorption than biosorption. These results confirm the degree of reduction UV254/UV0 and DOC/DOC0 for the same processes. EMS index also confirms the improvement of HSbiodegradation by sludge microorganisms.

Performance of cation and anion exchangers was evaluated by carrying out breakthrough analyses of pH, conductivity, free mineral acid (FMA) and various dissolved solids for an industrial water treatment plant of 700 gpm capacity. The breakthrough curves showed no leakage of calcium, magnesium and chloride throughout the operating period of the train, however, they indicated the early leakage of sodium, potassium, sulphate and silica. The operating/breakthrough capacity, total capacity and degree of column utilization were determined. The column utilization was found to be 67.85%, 38.93% and 16.78% against the design values of 90%, 85% and 85% for cation, primary and secondary anion exchangers respectively. The operating time of the water treatment train was significantly increased by achieving adequate capacity utilization of secondary anion exchanger. The low capacity utilization of secondary anion resin due to early silica slippage, has been discussed in the paper.

In the last five decades, the variation for increase in population and decrease in available clean water is noticeable. To meet with growing water requirements, along with the wastewater from municipal sewage treatment plants, it is critical to consider the reuse of industrial wastewater wherever possible. In the Indian context, this has already been started in some of the big industries, especially in metro cities and it must be implemented at all level possible industries. Ultrafiltration (UF), reverse-osmosis (RO) and membrane bioreactors (MBR) will be integral parts of this. Waste water reuse is not only a necessity, it also provides several eco-friendly benefits.
