Environmental Materials

The modified Eco-Bio-Block (EBB) has been studied and manufactured in Viet Nam, based on the process of blending friendly environmental materials as activated carbon, zeolite, kazemzite, sand and useful microorganisms. After culturing, bacterial communities in the modified EBB became significant abundant by DGGE analysis of 16S rDNA. The amount of microorganisms in the modified EBB was 107 CFU/g bacteria communities (Prokaryote). After 2 months treatment with the modified EBB, the quality of Khuong Thuong lake water has been significantly improved; the concentration of COD, NH4+, Coliform and Chlorophyll-a are reduced by 65.51 %, 64.28 %, 50 % and 68.42 %, respectively at the location A1. Sensuously, the lake water became brighter and cleaner. The application of the modified EBB to improve the lake water quality was conducted appropriately to the conditions at Vietnam in general and at Hanoi in particular. This research aims at localizing technology and improving efficiency on pond/lake water treatment. Further goal of the modified EBB application is to reduce pollutants in domestic wastewater form residential areas, in ditches, creeks and small lakes in Viet Nam.

Origin Point

Urban development, agricultural runoff and industrialization have contributed pollution loading on the environment.  In this study Hemavathi river water from a stretch from its origin point to its sangama was studied for pollution load by determining parameters of water quality like pH, Alkalinity,  Ca, Mg, Nitrate, TDS, BOD, COD , and the results were compared with WHO and BIS standards to draw final conclusion on the quality of water.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.
