Filter shell is made of high quality pecan shells as raw material, after crushing, polishing, steam cleaning, drug treatment, two screening processed. This filter high hardness, wear resistance, resistance, resistance to pressure 23.4kgf. Chemical stability, not acid-base dissolved, adsorption interception capability, it has the advantage of directly before the filter backwash water, low operating cost water filter shell, easy management, backwashing low intensity (6.7L / S㎡ ), filtration rate (24-26m / h), the effect is good, do not harden oil filter Nutshell media, it does not rot, and never replace Nutshell filter image, just add 5-10% per year can be. For oily wastewater treatment effect is remarkable, oil removal rate of 95%, oil drops 5mg / g or less. This filter after the relevant units to choose from, the general response of the effect is significant, is ideal for oil and other environmental equipment unit oil filler material. Cotton. The particle size of 1.6-2.Omm, 0.8-1.2mm, 0.5-0.8mm of filter 10g were slowly into a glass column in Nutshell filter, filling height of 12cm. Each added 1 OOmI, oil samples were collected oil sample volume [isl (2) filter thickness and the filtrate was poured into a weighed amount of simple filter: were taken inside diameter of 25mm 27mm 32mm glass column, stuffing cotton wool at the outlet... The worst effect of particle size using a filter (1. 6-2. 0 m resistant filter each "Og slowly into a glass column, the fill height respectively 8cm. 12cm.16cm. Each added 100mI, oil samples collected After the filtrate was poured into simple measure the amount of oil filter sample volume (3) Repeat filter: Use oil absorption rate of poor inner diameter of the two particle filling 32mm (1 6-2 Omm, 0. 8-1 2mm...) separation column, the column height 8cm. Repeat for the second exchange media filtration. The filtrate was poured into the amount collected after brief amount of filtered oil sample volume .1.2.2 suspension gravimetric filtration determined first before the oil sample were suspended weight . gravimetric force a suspension method as follows: filter paper was washed with distilled water to remove soluble matter, dried to constant weight weighed Buchner funnel into the well mixed sample 100m1 suction filtered through all of the moisture. filtration membrane. then every 1 OmI, washed twice with distilled water in a row, continue suction filtration to remove traces of water. Stop} After BU suction filtration, carefully remove the membrane containing suspended solids into the weighing bottle into 105 0C oven After 2 hours of drying in a desiccator 30mi. The temperature was cooled to room temperature, weight scales. then drying for 1 hour and weighed until constant weight (weight difference before and after the brink .. 002g is} Bu) ['4 a' s} then measured after the same power of a law suspending the weight of the oil sample was filtered German source water treatment (Figure) |..
