Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration in aquaculture waste. In this study, the agarophyte Gelidium elegans originating from Korea was investigated for bioremediation of tiger shrimp (Penaeus monodon) broodstock effluent (SBE) in a shrimp hatch...

In many regions throughout the continent, industries and farms struggle with low-quality water supplies. They threaten environmental health safety of drinking industrial waterways. The regeneration effluents is modeled in detail this study. Solar stills are designed to emulate natural evaporation, purifying effluent from processes. This approach best suited for small, off-grid structures that p...

Fish were collected from Nath Sagar, Paithan 50 kms away from Aurangabad and were brought to the laboratory and exposed to industrial effluent (tannery effluent). Behavioral changes and responses of the fish to the tannery effluent were observed. Control fish showed normal behaviour and swimming in contrast the effluent exposed fish showed abnormal swimming, loss of equilibrium, fading of colou...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...

The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle wastewater into high quality water. In this study, an attempt was made to compare the efficiency of aquatic macrophytes like Typha sp., Eichhorni...

Our interest in the “cold fusion” process [1,2] was piqued by the apparent lack of systematic investigation into the composition of the gaseous products produced during the electrolysis of D2O. A critical issue in determining whether or not the cold fusion process exists is the quality of the evidence concerning the composition of the gaseous products. The low intensity of neutrons has prompted...

A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge. The monitoring program was divided in two phases. The results of the first...

Phosphorus can be removed from wastewater biologically, chemically, or through a combination of the two. In this study, we applied environmental life-cycle assessment to develop a metric with which decision-makers can compare processes. Two phosphorus-removal scenarios were contrasted-one based on a desktop-level design and one based on full-scale operational data. To achieve 0.5 mg/L effluent ...
