The article is dedicated to the assessment of the experience in drainage water purification from radionuclides using ion-selective purification method on Units 1,2 Novovoronezh-2 NPP. Application of an ion-selective sorbent based on nickel ferrocyanide, as well as the preliminary oxidation of corrosive origin radiongjuclides, allow to achieve a satisfactory quality of purification from Cs-134, Cs-137, Co-60, Co 58, Mn-54, Cr-51. However, this method turned out to be ineffective for drainage water purification from Be-7, Sb-124, Sb-125. The article presents a possible method for drainage water purification from Be-7, Sb-124, Sb-125 using an iron-based coagulant, prospects for the modernization of the ion-selective drainage water purification plant, as well as plans to improve methods for drainage water purification at Novovoronezh-2 NPP

Water is the primary source needed to ensure human and other creature life continuity. There are a lot of water on this planet, but increasingly this water is not where it is needed or it is of inadequate quality (purity) for human consumption or other beneficial for example industrial, agricultural and so on purposes. Contaminated water supply causing harm to human body health and also contributes to extinction to the certain creature. Thus, water-saving or wise water usage is an important matter in Islam. Reuse of wastewater or sewage water is a solution to the water crisis problem faced nowadays. The contaminated water is purified and treated by certain processes. Water purification or treatment water is introduced to produce pure and clean water. However, discussions and debates among experts and societies continue to occur because the water is categorised as pure water but not purify (musta'mal) and impure water and not purify (mutanajjis). Therefore, this study aims to identify the concept and method of water purification and treatment (تطهير الماء) according to Fiqh perspective. Methodology of this study is qualitative approach by using document analysis by analysing several classic Fiqh books by four mazhab (Hanafi, Maliki, Shafie and Hanbali). Hence, this study can discover the water purification method suggested in Fiqh perspective to be applied by Muslim communities in Malaysia.

Nowadays global water quality pollution has become extremely serious, and solving water pollution has been extremely urgent, so researches on water pollution solutions have become even urgent. And flocculating method is the most traditional water purification method, research and create new high performance flocculating agent is one of flocculating method inherent problems. The paper mainly describes adding iron, zinc two kinds of metal captions together in polysyllabic acid, well controlling all aspects requirements in technology, researching and creating new water purification substance—poly iron and zinc silicate sulfate flocculants (PFZSS). PFZSS making method is weighting proper amount sodium silicate into container, and meanwhile putting it into water to dissolve, then utilizing dilute euphoric acid and sodium hydroxide to adjust silicic acid solution pH value and arrive at regulated scope, letting it to activate and arrive at certain time, slowly importing activated proper silica acid solution into moderate iron sulfate and zinc sulfate on the condition of fully blending, and finally putting and curing for a while. And implement experiment research on how mixed solution metal cations matching; making method, pH value, and silicon dioxide concentration these factors affect PFZSS overall performance. PFZSS application mainly takes catering industry sewage solution as an example to get PFZSS has very strong absorption capacity, owns good cleaning effects on extremely turbid catering industry treatment sewage COD and turbidity acquiring, its reaction formed flock density is great, sedimentation rate is very fast, so PFZSS will have great application prospects in the aspect of treating urban sewage.

Purification Method

A simple and inexpensive water purification method was developed using natural coagulant (Moringa seed powder) and antibacterial agents (scallop powder) followed by bio-sand filtration. In this study, surface water from different sources (e.g. pond, canal, lake and river) treated with combined Moringa seed powder, and scallop powder (MOSP) at a ratio of 2:1 for 10 minutes showed a clear water layer at the top and a sediment layer at the bottom. The clear water was then passed through an eight-fold sari cloth and/or natural bio-sand filtration and the resulting water was found drinkable. The microbiological and physico-chemical quality of this water showed non-significant differences compared to the US EPA drinking water quality parameters. Moreover, no cytotoxic effect of MOSP with BHK-21 and HeLa cells, nor any bacterial endotoxins were observed, indicating use of MOSP does not pose any adverse health effect. Furthermore, the quality of 6 months stored water at room temperature was found acceptable, indicating the usefulness of this technology for drinking water purposes. On the other hand, the sediment or sludge produced in this process could be used in agricultural fields after proper composting. Therefore, this simple, inexpensive and ecofriendly method could be used in drinking water scarcity areas of the world.

The article describes the diversity of oil products that are the main sources of wastewater pollution. The dissolved or liquefied oil forms a floating layer on the water surface. The large emissions of different crude oil sources and household waste into the environment cause great damage to wildlife. It is evident that many types of oil sources are carcinogens. The article provides information on emissions of toxic compounds of industrial enterprises into the atmosphere and their adverse effects, including on human health because toxic compounds can cause many diseases. The methods of biotechnological treatment by mechanical, physicochemical and biological purification of water sources contaminated with oil waste are discussed. In particular, the importance of biological purification, petroleum technology, and microbiological purification and nanotechnological methods of water purification has been widely examined. The article contains information on water purification method using microalgae, biological filters, and wastewater treatment through aerotanks. Methods to purify phenolic compounds from wastewater such as adsorption, ion exchange, liquid-liquid extraction, chemical oxidation, electrochemical methods, solvent extraction, precipitation and biodegradation are considered. The role of some economically efficient and promising methods of bioremediation to eliminate and neutralize petroleum hydrocarbons and some pollutants in removing phenolic compounds is analysed.
