'97 prospects for environmental policy. Role of the waste water treatment in farming district and the future development.

The present review highlights the different types of nano ferrites and their surface modified composites as an alternative adsorbent in waste water treatment. In this review, the recent progresses and potential applications of SFNPs/SFNCs for the removal of organic and inorganic contaminants through adsorption routes are critically reviewed. There are number of water purification techniques but the adsorption is one of the simplest, effective and economical method for wastewater purification. Adsorption isotherm models, kinetic models, thermodynamic parameters and adsorption mechanism have also been discussed. The present article lists different type of adsorbents and reviews state-of-the-art of the removal of different pollutants from water. The efforts have been made to discuss the sources of contamination and toxicities of pollutants. The possible techniques of recovery and reuse, toxicity, research gaps and the future perspective of SFNPs are also discussed in brief. Based on this review, it is possible to conclude that SFNPs and their derivative composites have unlimited capacity in addressing array of problems encountered in water and wastewater treatment. The present study highlights the future areas of research for waste water treatment.

The Future

Because of the greenhouse effect, global climate changes will adversely influence the water supply in the future. As can be seen in traditional reservoirs, the crisis will be exacerbated due to the reservoir‘s sedimentation. From a global view, 70 % of freshwater resources are used for agricultural purposes. Thus, water management and infrastructure changes are needed to improve the situation if current climate conditions continue into the future. In order to save water resources, an attempt to reuse a pond‘s wastewater for agricultural irrigation is proposed. Utilizing waste water treatment via nitrification (with nitrifying bacteria) and aeration processes, the plant will receive enough fertilizer extracted from fish dung. Additionally, to assure a safe environment, the temperature, dissolved oxygen, and pH (potential of hydrogen) value of the aquarium will be monitored online and shown on the interface of the server device. Various automatic functions such as an aquarium filtering system, a waste water treatment system, a plant irrigation system, a waste water aeration system, and a water retrieval system are also designed in the hybrid aquarium/plant system. Consequently, a prototype of a PC-based automatic plant/aquarium hybrid system is established.
