The main objective of this study is to confirm the potentials of Moringa oleifera seeds over alum for water purification. Various doses of Moringa seed powder 4, 8, 12 g/l were taken and checked for treatment of river and sewage water. After treatment of seed powder with water samples were analyzed for physico-chemical parameters like pH, Absorbance, TDS, TSS, Hardness, Chlorides, Conductivity, Turbidity, MPN and DO. Almost all parameters showed reduction with increasing dosage of Moringa seed powder. Similar doses of alum were checked with river water sample and were analyzed for above mentioned parameters. The results obtained showed that seed powder (natural coagulant) is more effective than conventional chemical coagulant., alum. The seed of Moringa oleifera is cheap, eco-friendly and non-toxic, can be effectively used as a coagulant for river and sewage water purification.

Cicer Arietinum (CA) or chickpea seeds were used as a local natural coagulant, cheap and cultivable which available in Egypt that can be used to reduce turbidity from wastewater, especially sewage water instead of chemical coagulant that causes different diseases like intestinal constipation, loss of memory, convulsions, so this paper represents the use of chickpea as a natural coagulant and eco-friendly in the environment because it assumed to be safe for the human health and efficient in sewage treatment 6, So the researchers advices now to use natural coagulant as coagulant aids which has a higher ability to raise the consistency of floc and prevent of the coagulation operation. The optimum removal conditions that applied on the research were temperature =250C, pH= 3, Contact time=120 min, agitation speed for 2 minutes =80 rpm (rapid mixing), (CA) dosage is 90 mg/L, and (95.89%) turbidity reduction was achieved on the studied area.

The objective of this investigation is to fabricate a natural material based composite and study its tensile strength. The water hyacinth is a plant which is considered as an unwanted wild growth which is detrimental to the water bodies. It affects the oxygen and nutrients content of the fresh and sewage water and also hampers the flow of the water, thus leading to stagnation and flooding. In this method the water hyacinth was harvested and used as a reinforcing fibre in its untreated condition [1]. Our nation having a long sea shore is blessed with coconut trees. All the parts of the coconut tree are being used for various purposes [2-4]. Based on literature 15% by weight of powdered coconut shell was used as particulate reinforcement in this study [5, 6]. Hence this experimental work is an effort to fabricate a composite using the waste water hyacinth fibres and the coconut shell powder using an epoxy resin matrix through hand layup technique and subjected to tensile loading. This test results show good ultimate tensile strength.

Denitrification Process

Chemically coagulated sewage water gives an effluent low in both suspended matter and organics. To use chemical precipitation as the first step in waste water treatment improves nitrification in the following biological stage. The precipitated sludge contains 75% of the organic matter in the sewage and can by hydrolysis be converted to readily degradable organic matter, which presents a valuable carbon source for the denitrification process. This paper will review experiences from full-scale applications as well as pilot-plant and laboratory studies.

Permitting Process

The contribution of accidental discharges to the total emission of contaminating substances in surface waters is relatively increasing, as regular discharges are reduced. In The Netherlands a program has been started to develop a quantitative risk analysis method to be used within the discharge permitting process. The methodology takes into account the type of activities and related accident scenarios in terms of failure frequencies and source sizes, correction factors according to specific circumstances, as well as the nature of the receiving system (types of surface waters, but also public sewage water treatment plants). The methodology will provide an indication of the risk reduction needed in terms of reducing the frequency and/or the volume of possible spills. The method itself, the use of it within the legal framework and the relation with the EC-Directives are discussed.
