Loading of water with multifarious pollutants has dwindled the availability of quality fresh water and put questions on reliability and efficacy of conventional water treatment technologies. Also the quest for developing robust and cost-effective methods with minimum impact on environment had driven the focus of researchers and technologists on new technological developments. Nanotechnology – better referred as Aqua-nanotechnology in this regard provides scientists a new dimension to deal this big problem with small particles having application in 1) water treatment, 2) remediation, and 3) pollution prevention. This chapter will focus on fabrication and use of advance nanomaterials categorized as nanoadsorbents and nanoatalysts for these three main areas. A range of materials exploited in this regard are single and mixed metal oxides and their composites with polymer, clay, carbon based materials etc. while keeping focus on technological developments taken place over the period in regard with treating water and waste water.

The use of treated wastewater to irrigate the sugar beet (<em>Beta</em> <em>Vulgaris</em> L. var. saccharifera) for bioethanol could play a strategic role to contrast the use of natural water resources and increase the productivity of the crop. The 2-year experiment (2013-2014) was performed on sugar beet irrigated with fresh water and wastewater at different steps of the reclamation process (secondary and tertiary treatments). The data obtained showed that the root sugar beet yield and ethanol production under fresh water treatment (52.2 Mg ha<sup>–1</sup> and 5446 L ha<sup>–1</sup>) were lower respect to that obtained from the secondary and tertiary wastewater treatments (66.7 Mg ha<sup>–1</sup> and 6785 L ha<sup>–1</sup>, and 58.7 Mg h<sup>–1</sup> and 6164 L ha<sup>–1</sup>, respectively), with the same irrigation volumes. These results can depend on the higher quantity of nutrient uptake when wastewater is used for irrigation. In particular, the average N applied (as nitrate and ammonium) with irrigation during the growing seasons (2013 and 2014) was corresponding to the supply of 4, 28 and 20 kg ha<sup>–1</sup>, for the fresh water, secondary, and tertiary wastewater treatments, respectively.

Influence Of Ph

Hot water and sodium hypochlorite (NaOCl) were evaluated to eradicate teliospores of the Karnal bunt fungus, Tilletia indica, for the purpose of decontaminating grain storage and handling equipment. The germinability of free teliospores and teliospores within the sori of infected wheat was assessed. Temperatures of 25, 60, and 80°C, NaOCl concentrations (wt/vol, pH 11.5) of 0, 0.53, and 1.60%, and immersion periods of 1, 5, 15, and 30 min were evaluated. In other tests, the influence of pH on NaOCl potency and of a delay between treatment and water rinsing were evaluated. Immersion at 80°C in water alone or with NaOCl killed both free teliospores and those within the sori of infected seeds within 1 min. NaOCl at 1.60% at 25°C killed teliospores suspended in water within 15 min, but some teliospores inside sori survived 30 min of this treatment. NaOCl adjusted to pH 8 before use was superior to NaOCl at pH 11.5. An application of 1.60% NaOCl at 25°C for 5 min followed by a 10-min delay before the seeds were rinsed in fresh water killed free teliospores but not all teliospores within sori. This treatment was more effective than the 5-min treatment alone but inferior to the 15-min treatment with NaOCl at a concentration of 1.60%. Because teliospores within the sori of infected seeds are partially protected and much more resistant to NaOCl, we recommend the removal and disposal of seeds from equipment before the treatments are applied. NaOCl radically altered the appearance of the teliospores, leaving a persistent visual indication that they had been treated, while hot water treatment alone did not. Therefore, it is beneficial to add NaOCl to hot water, although the improvement in the sporicidal efficacy was often small.

Water is inevitable for our life. Due to the population growth, there is a tremendous pressure on the existing fresh water resources such as surface water and ground water. Increasing water demand and improper usage of potable water lead to scarcity of fresh water resources. Globally, treating grey water is a real constraint to minimize the problem of water scarcity. The continuous flow-based constructed wetland system for grey water treatment is a technique for reusing the domestic grey water and it is a low-cost method. The current study was aimed to evolve a suitable user-friendly treatment system for handling the household grey water. In the present study, grey water has been collected from the Bharathidasan University and it has been treated with biofiltration and rhizhodegradation techniques using continuous flow-based constructed wetland system. The system has been found as more effective for treating the Physico-chemical parameters such as suspended solids, pH, electrical conductivity, TS, TDS, DO, BOD, COD, TOC, CO3, HCO3, SO4, NO3, PO4, Ca, Mg, Na, K, total hardness, calcium hardness, chloride, and total alkalinity. The results reported the reduction in the biological oxygen demand (89%), chemical oxygen demand (81%), DO (95%), carbonate (100%), sodium (65%), and potassium (85%).It also examined the benefits and risks associated with the results in the reuse of domestic grey water for the purpose of vegetable gardening, irrigation, and toilet flushing. Consequently, this biofiltration method is natural, simple, and low cost-effective treatment in a holistic manner.

Compressive Strength Of Concrete

This research was motivated by the use of sea sand to the availability of large amounts in Bengkulu city. The purpose of this study was to determine the quality of sea sand physically and to compare the compressive strength of concrete with the dunes and river sand. Sea Sand which were used in this study wereSelolongSea Sand, LakokSea Sand and Air Padang Sea Sand. The specimens were the cubical size 15 cm x 15 cm x15 cm of 40 samples with 2 types of treatment namely salt water and fresh water treatment. The planning of concrete used 0,5fasand 60-100 mmslump, The testing was done at 28 days. The result of this study showed that for doing the inspection of sand quality physically, all the tests fulfilled the requirement setexcept in the inception of sieve analysis for Air Padang sea sand, which has a very fine grain. The highestincreased of concrete compressive strength was atLakok Sea Sand, which was 3.86% of the dunes, and 4.77% for the treatment of river sand for freshwater. For the treatment of Lakoksalt water on the dunes increased to 2.22% and on the river sand increased 3.74%. Air Padang Sea Sand has the biggest reduction the compressive strength of concrete, most notably in the treatment of fresh water on the dunes of 10.33% and 9.54% of the river sand. For salt water treatment, Air Padang Sea Sand had a greater reduction which was 14.61% of the dunes and 13, 33% of the river sand.
