    • According to the invention there is provided a tertiary effluent treatment process for reducing the phosphate levels in effluent. The process comprises the steps of delivering effluent from a wastewater treatment plant to a primary filter, delivering the filtered effluent to a series of two or more phosphate removal filters, delivering the filtered phosphate-depleted effluent to a treated water tank as treated water, delivering the filtered phosphate-depleted effluent from the treated water tank to a discharge tank as treated water; and, discharging the treated water from the discharge tank as required. Each phosphate removal filter comprises a plurality of polymer-based beads having nono-particles of iron oxide coated thereon. The advantage of using a series of two or more phosphate removal filters is that the process can deliver a final effluent containing specific pre-dtermined levels of phosphate that may be as low as 0.01mg/L of effluent, but will in all cases be below 1mg/L. the series of two or more filters also allow the process to accommodate variations in the phosphate content of the effluent without affecting the level of phosphate in the discharge, and, the system can be retro-fir to the end of any type of existing waste water treatment plant or can be integrated into a new facility.

    • The present invention concerns an effluent treatment assembly and process for reducing the amount of phosphate in effluent sourced from a primary and/or secondary waste water treatment facility. The effluent treatment assembly comprises phosphate removal filters containing phosphate removing filter media. Each of the phosphate removal filter media comprises a macroporous ion exchange bead which has been impregnated with an ion adsorption material. The advantage of the invention is that both an ion adsorption process and an ion exchange process take place to remove phosphates from the effluent in a more efficient manner than has been heretofore known. The phosphate removing filter media is intermittently regenerated using regeneration solution. The effluent treatment process advantageously comprises means for recovering the regeneration solution after use for further re-use. The phosphate removed from the effluent is harvested and may be dehydrated and pelletised to be used as fertiliser pellets.
    • 本发明涉及一种用于减少来自初级和/或次级废水处理设备的污水中的磷酸盐的量的污水处理组件和方法。 废水处理组件包括含有磷酸盐去除过滤介质的磷酸盐去除过滤器。 每个磷酸盐去除过滤介质包括已经用离子吸附材料浸渍的大孔离子交换珠粒。 本发明的优点在于,离子吸附过程和离子交换过程都以比迄今已知的更有效的方式从流出物中除去磷酸盐。 使用再生溶液间歇地再生磷酸盐去除过滤介质。 流出物处理方法有利地包括用于在使用后回收再生溶液以进一步再利用的装置。 收集从流出物中除去的磷酸盐,并将其脱水并造粒以用作肥料颗粒。

    • The invention relates to a tackifier dispersion comprising a resinous material and an emulsifier, the emulsifier being obtainable by a method comprising providing an ester of one or more fatty acids containing at least two conjugated double bonds, reacting the ester with a dienophile containing an acid or anhydride group, to form an intermediate product A, and, reacting the intermediate product A with one or more polyalkylene glycols. The invention also relates to a method for the production of a tackifier dispersion, its use as a tackifier, and an adhesive composition comprising the tackifier dispersion. The invention further relates to an emulsifier, a method of producing the same and its use for emulsifying resinous materials.
