  • the first filter receives waste water via an inlet pipe 130, supplying filtered waste water to the second filter 110, via the connecting pipe 120. Filtered water is then supplied via an outlet pipe 140.
  • the apparatus may also include an optional pre-filter 150 for pre-filtering the waste water received via a pre-filter inlet pipe 160. In one example, the waste water may be received via a pump 170.
  • the waste water is typically pre-treated using existing techniques for removing solids and other contaminants. Accordingly, in this example, removing the heavy metal contaminants using the process described below is a secondary treatment process generally referred to as polishing.
  • the pre-treatment of water could be performed in any suitable manner and will not therefore be described in further detail.
  • the waste water is optionally pre-f ⁇ ltered, using the pre-filter 150, before being supplied to the first filter 100.
  • the pre-filter can be used for reducing turbidity and/or removing other contaminants such as suspended solids (SS) or the like, to avoid clogging problems downstream.
  • Any suitable pre-filter may be used, and in one example the pre-filter is a pressurised sand filter, although alternatively membrane or cloth filters can be used.
  • the first filter 100 filters the waste water to remove first heavy metal contaminants such as mercury based contaminants, or the like.
  • the first filter 100 is typically an ion exchange filter for removing positively charged ions and in one example is formed from a zeolite, such as clinoptilolite or another similar materials.

  • the second filter can also remove other contaminants such as nutrients includes nitrates, phosphates, or the like, other negatively charged ions, or other positively charged ions that have not been removed by the first filter (herein referred to as residual positively charged ions) thereby enhancing the overall performance of the system.
  • nutrients includes nitrates, phosphates, or the like, other negatively charged ions, or other positively charged ions that have not been removed by the first filter (herein referred to as residual positively charged ions) thereby enhancing the overall performance of the system.
  • the ion exchange filter typically it is preferred to remove the positively charged ions using the ion exchange filter first, allowing the majority of these contaminants to be removed, before the second filter removes any negative ions and remaining positive ions. This prevents the sorption filter capacity being exceeded by having the sorption filter attempt to remove all the positively charged ions, which can be adequately removed by the ion exchange filter.
  • zeolites are hydrated aluminosilicate minerals that have a micro-porous structure, represented by the chemical formula:
  • zeolites are complex, crystalline inorganic polymers based on an infinitely extending three dimensional, four connected framework of AIO 4 and S1O 4 tetrahedra linked to each other by the sharing of oxygen ions.
  • AIO 4 tetrahedra bears a net negative charge
  • zeolites typically naturally include positive exchangeable ions, such as sodium TVa + , K + , Ca 2+ , and Mg 2+ ions, embedded within the micro-porous structure.
  • zeolites such as clinoptilolite are naturally occurring and can be mined using open pit techniques in many regions. Consequently, zeolites, and particularly clinoptilolite, are cheap and readily available, thereby making them practical for use as a filter material for the first filter.
  • Zeolites are typically mined as large rocks, which are therefore unsuitable for use in a filter bed. Accordingly, the zeolite material is typically crushed or ground into smaller fragments of desired particle diameter such as between ⁇ -5mm. This increases the available surface area, thereby enhancing the filtering process, and reduces gaps between adjacent fragments, thereby ensuring that all the filter bed contains material.
  • the actual size used can depend on a number of parameters, such as the flow rate of the oil processing waste water, the relative expected level of contaminants, or the like. Thus, for example, a high concentration of contaminants would generally require a greater surface area to ensure adequate filtering, and accordingly a smaller particle size would be preferred. However, with low contaminant concentration but a high flow rate, less filtering is required, whilst a higher throughput is preferred, thereby making a larger particle size, say 3 -5mm, more appropriate. However, it will be appreciated that the examples quoted are for the purpose of illustration only and that in practice any suitable particle size may be used.
  • the grinding process generates dust that can clog pores of the clinoptilolite, resulting to lower sorption capacity due to the reduced available ion exchange surface. Whilst washing with water can reduce this clogging, typically washing with water alone is unable to remove all the dust from the clogged pores.
  • the effectiveness of the crushed zeolites is enhanced using chemical conditioning, which involves exposing the zeolite to a high concentration of salt water solution. This can be performed by washing the grinded zeolite in a sodium chloride solution.
  • the high concentration of Na + ions causes any other ions present, such as more positively charged Calcium Ca 2+ ions to be displaced, thereby maximising the effectiveness of the ion exchange process.
  • Arsenic contaminants such as arsenate and arsenite, typically form negative ions in solution, such as As 3' , and consequently are not suited for removal using ion exchange in the zeolite filter. Accordingly, the second filter typically uses a laterite based sorption filter.
  • Laterites are formed by leaching of and enrichment with aluminium and iron oxides of silica based rocks. Laterites typically include minerals such as kaolinite, goethite, hematite and gibbsite, and therefore contain in various ratios. Laterites can include soft porous material, as well as hard, dense rocks, depending on the nature of the parent rock and the weathering that has occurred.
  • Porous laterites have a high surface area, and in use the arsenic ions bind to the surface of the laterite, becoming embedded therein.
  • the filtering ability is therefore directly related to the surface area of the laterite. Accordingly, a porous laterite is preferred, and the absorption capabilities can be enhanced by treating the laterite with 0.01 M HNO 3 , which increases the specific surface area.
  • this is not essential, and it will be appreciated that laterite can be used without pre-treatment, thereby helping to minimise costs for the filtering apparatus.
  • the need for the pre-f ⁇ lter will depend on the typical purity of the waste water, and accordingly in some instances this may not be required, although reducing clogging downstream can significantly extend the life and improve the efficiency of the downstream filter processes, thereby making the use of the pre-filter advantageous. Additionally, as the pre-filter can generally be cleaned by backwashing, there is little expense involved in the use of the pre-filter. As such filter materials are cheap and readily available, this allows for low cost treatment of oil processing waste water, which in turn allows for the refining of previously marginally economic crude oil.
  • the first filter is an upflow filter
  • the second filter is a downflow filter. This allows the filters to be used in sequence, as will now be described with reference to Figure 3.
  • the first filter 100 includes a first filter housing 300 defining a first filter cavity 301 having a first filter bed 302 provided therein.

  • waste water when waste water is pumped into the first filter cavity 301 via the inlet pipe 130, waste water will fill the first filter cavity 301. As waste water passes through the first filter bed 302, the water undergoes an ion exchange filter process, thereby removing any positive charged heavy metal based contaminants such as mercury.
  • the water level continues to rise until it reaches the level of the outlet 304, allowing filtered waste water to exit the first filter 100, through the connecting pipe 120, thereby entering the second filter pipe 315.
  • the rate of inflow and the size of the apertures is selected to allow the second filter pipe 315 to contain a sufficient level of waste water to allow waste water to flow through all of the apertures 316, thereby allowing the waste water to be dispersed evenly over the second filter bed 312.
  • the waste water is then filtered to remove the arsenic based contaminants as it drains through the second filter bed 312, before being supplied via the second filter outlet 314 to the outlet pipe 140.
  • This arrangement allows a pressurised sand filter to be used to drive the entire process.
  • the pressurised output from the pre-filter 160 allows the first filter cavity 301 to be filled with waste water, whilst natural drainage from the first filter 100 allows the second filter 110 to operate.
  • This arrangement also has the further benefit that filters such as clinoptilolites tend to work best in an upflow mode, whilst laterite filters tend to work best under conditions of down flow, which is satisfied by the above described arrangement, whilst still only requiring the use of a pressurised sand filter to drive the system.
  • a pressurised filter is not essential in this configuration and alternatively the system can be driven using other suitable pumps.
