ABSTRACT:Water pollution has always been a major problem in the environment. Polluted water is harming for human health and need to clean water from pollution factors. One of the economic and rapid methods for elements removal is displacement metals by biosorption. The purpose of this study was refining diluted compost latex by Ceratophyllum demersum that was diluted 200 times with distilled water. Diluted compost latex (DCL) accompany with aquatic plant Ceratophyllum demersum was located in bottles which were 6 liter in four replication. The experimental performed at the open air of Khorasgan (Isfahan, Iran) University area for 18 days without aeration. Result of Chemical oxygen demand (COD) indicates that the COD was decreased from 728 mg/L to 189.5 mg/L. Also, this investigation was demonstrated that the amount of ammonium in diluted compost latex was decreased from 60 meq/L to 13.33 meq/L. The amount of nitrate in diluted compost latex has decreased from 90 meq/L to 26.66 meq/L, and the amount of Phosphorous was declined from 1.2 meq/L to 0.21 meq/L. EC of diluted compost latex was reduced from 1.02 ds/m to 0.74 ds/m. All of the consequences which were mentioned indicated that this aquatic plant (Ceratophyllum demersum) is one of the best natural ways to refine Polluted water. @ JASEM

“…The "Garden -Livestock farm" is a popular system worldwide which plays an important role in rural economic development: increase the cultivation yield, soil remediation, and reduce of cost for fertilizer and livestock food [2]. This system has found an application in various developed countries such as in the USA [2][3][4][5] and in France [6,7]. Kaufmann developed a low carbon emission system applied for livestock farm in which the livestock waste and food garbage were used for biogas digestion, the methane gas was then collected and use for cooking at the household kitchen and/or filtered and stored for supplying outside, and the residue and wastewater after biogas digester were used as fertilizer [8].…”

“…This research indicated that domestic wastewater could be treated when using that system and the effluent quality reached the country's environmental standards as required [16]. There are also many studies on wastewater treatment by using pond, lake, and plant ecosystems [17], water hyacinth and buffalo spinach [18], water hyacinth culture-algal culture-water hyacinth culture [5], Eichhornia crassipes-a water hyacinth species [19], cattail (Typha sp. ), and reed (Phragmites sp.)…”

Background: The sedge mats (dyeing, weaving processes, and small-scale livestock farm at the same place) craft villages in the Mekong Delta (Vietnam) are the most popular craft villages in Vietnam, especially in the Mekong Delta area. These craft villages generate typical emissions such as exhaust gas from burning fuel, wastewater from the sedge mats dyeing and weaving process, wastewater from livestock farm, and solid waste. Methods: In this study, an ecological system, so-called VICRAIZES (Vietnam Craft villages Agro-based Industrial Zero Emission System), has been developed with the purpose to decrease pollution and enhance resource efficiency at those craft villages. The proposed ecosystem focused on measures such as (1) biogas tank (using residue pieces of solid sedge mats from weaving processing) supplied gas for burning the dyeing tank, (2) wastewater treatment system combining three components: innovative septic tank having upward flow thin baffles, anaerobic filter compartment, and bio-pond, and (3) composting area. The system was applied for a number of household craft villages in Dong Thap Province, Vietnam. Results: The results of system demonstration show significant emission decreases: 93 % greenhouse gas (CO 2 and CH 4 ), 97 % BOD 5 in wastewater, around 30 kg/day biodegradable garbage are composted and used as organic fertilizers at the household needs (which increase family income of around 115 million VND/year), low initial investment and operating cost, simple operating procedure, etc., which are favorable and applicable at the low income sedge mats dyeing and weaving craft villages in the Mekong Delta area, Vietnam, and probably at other developing countries. Conclusions: The VICRAIZES system implementation shows remarkable benefits/advantages on environmental, economic, and technical aspects giving real chances for more comprehensive application at similar craft villages in Vietnam and possibly in other developing countries.

“…Research with aquatic macrophytes has centered in the past on determining effective eradication techniques for nuisance growths of several species such as Elodea canadensis and Ceratophyllum demersum (Nichols, 1991). In addition, considerable research has been conducted to determine the usefulness of macrophytes as biomonitors of polluted environments (Haslam, 1982;Sortkjaer, 1984), and as bioremediative agents in wastewater treatment (Tripathi & Shukla, 1991). When macrophytes have been used in toxicity tests, the duckweeds (Lemna spp.)…”
