The present work is aimedto analyze Physico-Chemical parameters of wastewater effluent from a dairy industry in Chennai. The dairy industry which was taken for study purpose involves processing of raw milk into products like consumer milk, butter, cheese, ice-cream’s and other milk products.Considering the increased milk demand, the dairy industry in India is expected to grow speedily and have the waste generation and related ecological problems are also assumed increased importance. An attempt has been made to study the Physico-chemical characteristics of waste water generated from dairy industry near Chennai in Tamilnadu state of India. Waste water samples werecollected from the dairy industry and analyzed for pH, EC, TSS, NO3-, PO4, Cl-, Fe, BOD, COD, oil & grease

The waste water generated by the tanning industry are the potential sources of pollution in Tiruchirappalli district. The tannery effluent can cause serious impact to water and soil. This study evaluates the physico-chemical characteristics of tannery effluent and soil. The chemical and physical parameters and water quality index of tannery wastewater were observed to be toxic as it contains large values of organic and inorganic chemical elements.  The tannery effluent contains large values of TDS, EC, anions and cations. The major pollutants in tannery effluents are high chlorides, sulphide and total dissolved solids (TDS). The organic impurities in tannery wastewater are the cause for its bad odour. Tannery wastewater polluted soil was analysed and found to have high values of PH, ESP(Exchangeable sodium percentage), EC,  sodium, chloride, sodium adsorption ratio, micronutrients and macronutrients and low values of organic matter, moisture content, phosphorus, potassium, nitrogen,  than the garden soil Unpolluted soil.

Sugar industries have an essential place in Indian economic development. However, the waste water generated from these industries poses a significant threat to the environment as well as irrigated land. If untreated effluents are used in irrigation, they might contaminate food crops and, if they are released into water bodies, they might also be dangerous to the survival of the aquatic ecosystem. The Physico-chemical characteristics of the content in the effluents from Sri Cham Sugars Private Limited, Bharathi nagara Sugar mill have been explored. Physico-chemical characteristics included color, odor, temperature, pH, BOD, COD, TDS, TS, DO, Chloride, Sulphate, Nitrate, Calcium, Magnesium, Sodium, Potassium, oil and grease, Electrical conductivity of the effluent collected from the different sites at discharge point in different months have been determined.

Inflammatory Effect

The paper presents the synthesis of a new complex combination of a Bis-Schiff base with Mn(II) ions with great potential for antimicrobial and anti-inflammatory activity. A new complex of the Salen-type ligand, 1-ethyl-salicylidene-bis-ethylene diamine was synthetized using Mn(II) ions. The chemical structure was confirmed through 1H-NMR and IR spectroscopy. The antimicrobial activities of the Bis-Schiff base and its complex were tested in comparison with Ampicillin, Chloramphenicol, Tetracycline, Ofloxacin and Nystatin. Those compounds were found to be active against Gram-positive or Gram-negative bacteria, and had an anti-inflammatory effect comparable to that of Indomethacin.

This study was designed to determine tlie occurrence and removal of Cryptosporidium spp. oocysts and Giardia spp. cysts, in municipal waste-water by waste stabilisation ponds in tlie Republic of Kenya. Eleven waste stabilisation pond systems located in towns across Kenya were included. A total of 66 waste-water samples were examined for the presence of oocysts and cysts, comprising 11 raw waste-water and 55 pond effluent samples over a two month period. Cryptosporidium spp. oocysts were detected in 6 and Giardia spp. cysts in 9 of the designated pond systems analysed demonstrating their ubiquitous nature throughout Kenya. Oocyst levels detected in raw waste-water samples ranged from 12.5 - 72.97 oocysts/l and various pond effluents between 2.25 - 50 oocysts/l. Cyst levels detected in raw waste-water samples ranged from 212.5 to 6212.5 cysts/l and in various pond effluents from 3.125 to 230.7 cysts/l. No Cryptosporidium spp. oocysts were detected in the final effluent from any pond systems studied (11/11). Whereas no Giardia spp. cysts were detected in the final effluent from 10 of 11 waste stabilisation pond systems studied, one pond system was found to be consistently discharging cysts in the final effluent at concentrations ranging from 40 to 50 cysts/l. The minimum retention period for the removal of Cryptosporidium spp. oocysts and Giardia spp. cysts was 37.3 days. Laboratory experiments were performed to assess physico-chemical and microbiological parameters to express relationships between pond performance and protozoa removal.
