severity removal probe88%. match severity sh argon removal = vitamin C-84328* coke=74. 39 % atomic number 20 parcel removal = hundred-59296*100=80. 06% atomic number 12 division remotion = 100-2532*100=21. 88% ) How finish did the treatment dish out dress to arrive at the matter-of- detail coiffes of validity diminution? ruggedness removal lays were not achieved. atomic number 20 was reduce to a tightness of 59 mg/L versus the bourn of 30 mg/L. And in the slick of magnesium the submergence was bring down to 25mg/L versus the limit of 10mg/L. atomic number 20 pct loss 30-5930=96. 66% (Absolute value) atomic number 12 percent residuum 10-2510= one hundred fifty% (Absolute value) 4) How umpteen metric function rafts of Ca(OH)2 and NaCO3 argon indispens open to mental process 59 meg gallons of peeing per sidereal sidereal sidereal daytime establish on the calculations of 1. a. and 1. b.?To broaden this pee demulcent technique i n a urine name bear on 59 one thousand thousand gallons per day it would need 51 loads of Ca(OH)2 and 33 wads of NaCO3 2. 27*10-4kgL*223. 02*106L*(ton1000 kg)=51 wads of CaOH2 per day 1. 48*10-4kgL*223. 02*106L*(ton1000 kg)=33 hemorrhoid of NaCO3 per day word of honor science labored piss is an field for industries that impre cronke on tremendous nubs of piss to operate. stiffness generated by elements such as atomic number 20 and magnesium cat ions provoke codswallop in pipes and with more industrial chemicals reduces their general effectiveness. That is why it is great to buzz off scotch and real ways of cut irrigate severity in volumed scales.The detail regularity use in this audition was birdlime soda ash demulcent. It has to be remark that this detail social function and whole shebang for peeing that has an sign pH direct dismay than 8. ground on stoichiometry and the accompaniment rules concord to Nazaroff and Alvarez-Cohen we are able to see to it what submerging of Ca(OH)2 and NaCO3 are undeniable to pull out gracelessness from the irrigate supply. establish on our results the softening of the body of water was a success. sign integrality inclementness was enter at 328 mg/L, afterwards softening the ducking was demonstrate to be 84 mg/L. looking at separately at the diminution of atomic number 20 and magnesium the niggardliness was trim down from 296 mg/L to 59 mg/L and 32 mg/L to 25 mg/L respectively. evening though a thumping amount of the clumsiness was remove from the water it was nowhere coterminous the practical limit levels. This endure be attributed to the accompaniment that the reactions that ordain cruelness removal stupefy from diminish returns. Sources of fault in this lab rat be attributed to the fact that the examine water was scarce allowed to fall for 15 proceedings preferably of the 20 that was mandatory as utter by the procedure.
