            BGWT開發了一個突破性的殺藻產品,這個產品外層包裹了一層可使它漂浮在水面、并有緩釋效果的物質,可以及時、經濟、有效地控制藍藻水華。它的特性使它在水中能立即起效,并不局限于水體的面積和形狀,因此保證了安全經濟的在水體中施用操作。

            Copper sulfate (CuSO4?5H2O)

            Copper(II) sulfate pentahydrate (CAS # 7758-99-8)  is an odorless and a very potent algicide approved under the US EPA for water reservoirs including potable water sources. It is used in large quantities in aquaculture and contained artificial ponds, where toxicity is a minor issue.

            The Lake Guard Blue? is designed to minimize the dosage  as well as the operational costs associated with the application of copper sulfate to a fraction of their current levels.

            銅(II)硫酸五水化物(CAS # 7758-99-8)是一種無味和一個非常強大的殺藻劑批準根據美國環保署等水庫飲用水來源。它包含大量用于水產養殖和人工池塘,毒性是一個次要問題。

              The Lake Guard Blue?旨在減少劑量以及與應用程序相關的運營成本的硫酸銅的當前水平的一小部分。

            Sodium Percarbonate (2 Na?CO? · 3 H?O?))

            Sodium Percarbonate (aka ‘Sodium Carbonate Peroxyhydrate’; CAS# 15630-89-4) is an odorless algaecide composed of Soda Ash and Hydrogen Peroxide (H?O?) which is considered to be the most environmentally friendly algaecide commercially available for the treatment of cyanobacteria. However, and although approved under the US EPA, its overall usage is quite limited. The major reason this compound did not establish itself as a viable solution are high operational costs. In addition, and unlike copper or chlorine-based compounds, its active oxygen concentration is relatively low, badly impacting its potency – especially in the context of a full lake treatment and the potential for dilution.

            Moreover, the use of liquid H?O? poses serious dangers, as large quantities of the compound have to be carried on boats where they may cause significant safety issues, including combustion or physical exposure to leaks.

            In contrast, the Lake Guard H?O?? dramatically reduces the operational costs associated with the application of hydrogen peroxide, as the product travels independently on the currents along the cyanobacteria. Its ability to effectively target the cyanobacteria spatially as well as vertically, further reduces the overall input required to achieve effective concentrations of H2O2 where needed. Coming in dry, granular form, it requires no special preparation or equipment reducing unneeded exposure by operators to a minimum.

            過碳酸鈉(又名“碳酸鈉Peroxyhydrate”;中科院# 15630-89-4)是一個無味的除藻劑由碳酸鈉和過氧化氫(H?O?),被認為是非常環保的滅藻商用藍藻的治療。然而,盡管美國環保局批準,其整體使用是相當有限的。主要原因這種化合物沒有建立本身作為一個可行的解決方案是高運營成本。此外,與銅或霍亂化合物不同,其活性氧濃度相對較低,嚴重影響其效力的環境——尤其是在一個完整的湖治療和潛在的稀釋。

              此外,使用液體H?O?帶來了嚴重的危害,大量的化合物必須進行船只,他們可能會導致重大的安全問題,包括燃燒或身體接觸泄漏。

              相比之下,The Lake Guard Blue H?O??大大降低了啊

            Calcium Hypochlorite (Ca(ClO)?)

            Calcium Hypochlorite (CAS# 7778-54-3)  is commonly used as an algicide (under NSF/ANSI 60 where it is limited to 15 mg/l), as well as a bactericide, deodorant, disinfectant, fungicide and so on.

            Hypochlorite is widely used in the  cooling-water systems of power plants. These facilities have been authorized by regulators worldwide to treat the systems with chlorine in order to avoid biofouling. Free chlorine is later being discharged in massive quantities to adjunct water bodies. This method is regarded as ‘the best available method’ in terms of biocidal efficiency and cost effectiveness (Hergott et al., 1978). The US Code of Federal Regulations (40 CFR 423) dictates limitations on the concentration of free-chlorine and the permissible amount of chlorinated water discharge to be released into a water body per day per reactor. And yet, a power plant with a standard daily flow of five million cubic liters can release up to 200,000 kg of free-chlorine into the adjacent pond on an annual basis (see Table 3.1 in Pacey et al., 2011). Comprehensive environmental studies that have been conducted by various environmental protection agencies showed that this mass discharge of chlorine had insignificant adverse effects on fauna and flora (e.g. Brungs, 1973; Hergott et al., 1978; Sung et al., 1978; Pacey et al., 2011; Ma et al., 2011). Moreover, studies also showed that residual chlorine byproducts from these practices, such as trihalomethanes, were found below harmful levels (Hollod and Wilde, 1982; Jenner et al., 1997; Jenner and Wither, 2011).

            Nevertheless, hypochlorite of any type has never been registered as an algaecide for freshwater bodies and therefore is currently not approved for use as an algaecide in surface water.

            BlueGreen’s past field trials with this compound have confirmed that treatment with chlorine concentrations of under 5 g/m2 had no effect on fish, seabirds or turtles.

            Moreover, our hypochlorite-based formulation (Lake Guard White?) was found to fully release its chlorine content within 60 minutes from application and to interact with the existing organic load in the water, after which total-chlorine could not be detected in the water (<0.01 ppm). In contradiction to in-vitro tests done in purified water (i.e. Clasen and Edmondson, 2006) this rapid interaction released all bound chlorine regardless of the pH range in the ponds (~pH 8.0).

              次氯酸鈣(Ca(ClO)?)

              次氯酸鈣(CAS # 7778-54-3)通常被用作殺藻劑(NSF / ANSI 60,限于15 mg / l),以及殺菌劑,除臭劑,消毒劑,殺菌劑等。

              次氯酸鹽廣泛應用于電站的冷卻系統。這些設施已經被全球監管機構授權處理系統與氯為了避免生物淤積。游離氯是后來出院了大量兼職水體。這種方法被認為是“*好的方法”的殺生的效率和成本效益(Hergott et al .,1978)。美國聯邦法規(40 CFR 423)規定限制游離氯的濃度和容許量的氯化水排放被釋放到水體每天每個反應堆。然而,發電廠和一個標準的每日五百萬立方升流可以釋放多達200000公斤的游離氯鄰池塘

            Phosphate Binders

            Phosphate is a well known factor in cyanobacterial succession over other microorganisms in aquatic habitats.  It is therefore logical that eliminating phosphates from the water leads to a decline in cyanobacterial infestations. Compounds such as aluminum sulfate and Phoslock efficiently bind to phosphates and sink to the sediment. In some cases, treatment of a whole lake with these compounds may prevent a few seasonal blooms.

            Similar to treatments with copper sulfate and hydrogen peroxide, treatments with phosphate binders are applied subsurface, thus limiting the feasible scale for treatment, making it extremely expensive.

            While considered a “preventative” measure against cyanobacterial blooms, the treatment is only effective to the extent it is able to bind with sufficient amounts of phosphate in the water. Given the abundant sources of phosphates from catchment areas, the effect of these  treatments is usually short-living. In addition, and although seldom addressed, treatment with phosphate binders include drastic amounts of binders, which in turn “rains” over the  sediment and chokes it. It is important to remember that bound phosphates remain in the ecosystem and under some conditions (heavy storms and water mixing)  can be re-released into the water column. Worse off, the bound phosphates are regularly consumed by “bottom feeders” such as carp and are easily disturbed and compromised by normal wind and wave action in shallow lakes.

            Considering the overall (limited) demand to treatment with alum salts, BlueGreen is currently developing an alum-based product, the Lake Guard Alum?, which will  remove all operational obstacles associated with aluminum treatment for end users wishing to implement it.

              磷酸鹽粘結劑

              磷酸是一個眾所周知的因素在藍藻繼承其它微生物在水生棲息地。因此,邏輯消除磷酸鹽的藍藻水下降導致的病害?;衔锶缌蛩徜X和Phoslock有效結合磷酸鹽和下沉沉積物。在某些情況下,治療整個湖與這些化合物可能阻止一些季節性的花朵。

              類似于治療硫酸銅和過氧化氫,治療與地下應用磷酸鹽粘結劑,從而限制了可行的治療,使它非常昂貴。

              而被認為是對藍藻的“預防”措施,治療僅是有效的在某種程度上它能夠綁定有足夠數量的磷在水里。鑒于磷酸鹽從集水區的豐富來源,這些治療的效果通常是short-living。此外,盡管很少解決,治療

            Barley / Rice Straw

            Placing barley or rice straw into aquatic ecosystems has been practiced in some places with an inconsistent effect. A recent discovery of the active compounds released from the straw (flavonolignans salcolin A and B) did demonstrate a lytic effect on Microcystis aeruginosa. However, these active compounds are not commercially available and have yet to obtain the required environmental and regulatory clearances which are likely to require long-term toxicology and environmental-impact studies.

              大麥/稻草

              把大麥或稻草水生生態系統已經在一些地方不一致的影響。最近發現的活性化合物釋放稻草(flavonolignans salcolin A和B)演示了對綠膿微胞藻屬溶解性的影響。然而,這些活性化合物還沒有商業化,并獲得所需的環境和監管許可,可能需要長期毒理學和環境影響研究。
