Bioremediation uses various microorganisms to detoxify or degrade various harmful substances in the nature, particularly soil and water. In the proposed work, five species of micro-organisms were used to analyse their impact on various physico-chemical parameters of water. In the first attempt the actual physico chemical parameters of the collected sample water were noted down (Fresh sample parameters). Then the sample water was treated with micro-organisms (one at a time). The growth of microbes was noted carefully over 96 hours after inoculation. The physico chemical parameters were recorded again and were compared with the fresh sample parameters. The results were analysed for any change and on this basis an impact factor was developed. The study reveals all the selected microbes have a great capacity of degrading and simplifying the complex molecules into simpler ones. Bioremediative treatment further enhances this capacity and therefore this approach can be utilized on large scale to minimize pollution of water bodies.DOI: http://dx.doi.org/10.3126/ijasbt.v2i2.10146Int J Appl Sci Biotechnol, Vol. 2(2): 132-134

Warm concentrated industrial wastewaters are preferably treated in an anaerobic reactor for reasons of energy generation and low surplus sludge production. Problems to be solved in the practical application concern a low growth rate of the micro-organisms, their low settling rate process instability, and the need for after-treatment of the noxious anaerobic effluent which often contains NH4+ and HS−. The use of biomass immobilized on small suspended carriers (< 0.5 mm) has proven to be a suitable mean to overcome most of these problems. Results are presented on–pilot and full-scale pretreatment of industrial wastewater in an anaerobic 2-stage fluidized bed reactor for CH.-production.–laboratory and pilot scale post-treatment of the anaerobic effluent, which contains NH4+. and HS2− in an aerobic air-lift suspension reactor for the production of NO3− and SO4−.

Ayurveda is concerned with the maintenance of life and the healing of illnesses that present themselves in the human body. Several herbal and Herbo mineral preparations have been explained in Ayurveda for the treatment of disease. Standardization is necessary to ensure batch to batch consistency, as well as for routine drug preparation on a large scale. Modification of old dosage forms and development of new dosage forms is an evolving process that leads significantly to the flourishing of science with a transforming lifestyle and people's interest. The preparation of granules consists of a refined form of Ghana (solid herbal extract preparation) and Khanda Kalpana (solid preparations similar to granules). Shalmali moola granule is a formulation for its beneficial properties such as, Balya (immuno-modulators), Rasayana (rejuvenator), Vajikarana (aphrodisiac) etc. Present study has elaborated standardization, physio-chemical parameters, Qualitative analysis and Chromatography (HPTLC) of Shalmali moola granules. Granules were prepared by adopting reference of Bhaishjya Rantavali and This study will be useful for standardization of Shalmali moola granule and for the preparation of the monography of this formulation for the Ayurvedic Formulary of India (AFI).

In Tirunelveli and Thoothukudi districts Tamirabarani River is flowing continuously for 120km (24km in hilly terrain and 96km in plains) and drains into the Bay of Bengal at Punnaikayal village. In this present study, physico chemical parameters of some selected areas of Tamirabarani River water of Tirunelveli, was analyzed from 2013 to 2016. Seven sampling points were selected and the water samples were examined. The parameters such as chloride, sulphate, total alkalinity, calcium, magnesium and hardnesswere analyzed.  Paper industrial waste, textile pollutants and temple waste are added to this point. These are the main sources of pollutants of Tamirabarani River. Tamirabarani is a main source of water supply to many towns which include Tirunelveli Corporation. In Tirunelveli corporation area the drinking water is not treated properly. Entire flow on the river has turbidity. The main aim of this paper is to analyze the various pollutants of Tamirabarani River by selecting seven different sites.

Abstract: The physico-chemical properties and detection of heavy metals (Viz. Pb, As, Cd, Ni, Cu, Fe, Zn, Cr) and their accumulation have been studied in electroplating industrial waste water. This work describes the detection of concentration of these metals in industrial waste water by ICP-AES (Inductively Coupled Plasma Atomic Emission Spectroscopy) technique. In electroplating industrial waste water samples Pb, As, Ni, Cu, Fe, Cr are detected while Cd, Zn, As, Cu are detected in trace amount in some samples. For the accumulation of metals by the waste water samples were collected and analysed. This concentration of metals is due to various electro plating industries. The waste water samples were collected from MIDC, Ambad, Nashik. Maharashtra. At this point the soil is getting polluted by the disposal of different electro plating industrial waste water. Detected some of the metals are toxic. Keywords: Accumulation, Heavy Metals, ICP-AES, waste water, detection, physico-chemical

Industrial Waste Water

A higher percentage of dyes from the industrial waste water are being released into aquatic ecosystems and polluted the natural ecosystem. An abundance of technologies available for removal of Dyes from the industrial waste water are expensive and ineffective. Many of these processes are economically not viable for small and medium scale industries due to large scale applications.Recent Investigational researches have proved that the successful elimination of dyes is obtained using numerous economically available non-conventional adsorbents also. Several experimental investigations on adsorption provedthattremendous treatment for dye removal and can be obtained using cheaply available non-conventional adsorbent.This review is mainly focused to the systematic study on utilizing low cost absorbent of dye removal from the effluents discharged from the industries. The data on economically cheap adsorbents and its properties for removing dyes resulted from the recent literature survey are summarized. Therefore, this review provides the various methods to treat the wastewater using low-price natural sources of adsorption materials, non-viable biomaterials.

Experimental Design Methodology

Photochemical advanced oxidation processes (AOP) for the treatment of waste waters containing biocidal or non-biodegradable organic compounds rely mainly on the production of a potent oxidizing agent, the hydroxyl radical. The Fenton's reagent, a mixture of hydrogen peroxide and ferrous ion, represents one possible source of hydroxyl radicals and it has been shown recently that degradation rates may be significantly enhanced by UV/visible irradiation. In this context, we have investigated the feasibility of a large scale application of the light-enhanced Fenton reaction to the treatment of a highly contaminated industrial waste water containing toxic aromatic amines (dimethyl anilines or xylidines) as the main pollutants. Following preliminary laboratory tests performed on the model compounds, 2,4- and 3.4-xylidines (200 mg/L, 2 L), experimentation on the industrial waste water at a large scale level (3000 mgC/L, 500 L) has been carried out using the experimental design methodology for the simulation and the evaluation of the effects of the two critical factors, hydrogen peroxide and ferrous ion concentrations. The light-enhanced Fenton reaction has been proven to be a most effective treatment process under acidic conditions and might be an alternative to adsorption of xylidines on activated carbon as used at present.
