Pehea e hana ai ka Aluminum Sulfate i ka mālama ʻana i ka wai

II. Nā hiʻohiʻona noi a me nā manaʻo hana:
I ka mālama ʻana i ka wai inu, hoʻohana pinepine ʻia ka alumini sulfate me nā mea kōkua coagulant—e like me ke kalapona i hoʻāla ʻia a i ʻole polyacrylamide—e wehe pono i ka turbidity, algae, a me nā mea organik. I ka mālama ʻana i ka wai ʻino ʻoihana, pono e hoʻoponopono ʻia ka nui o ka alumini sulfate ma muli o ka waiwai pH o ka wai: ma lalo o nā kūlana acidic, holo pono ka hydrolysis o nā ions alumini; akā naʻe, hiki i ka nui o ka dosing ke hopena i nā pae alumini koena i loko o ka effluent i mālama ʻia e ʻoi aku ma mua o nā palena hoʻoponopono. I ka ʻaoʻao ʻē aʻe, i nā wahi alkaline, pono e hoʻohui i nā mea hoʻoponopono pH (e like me ka lime) e hoʻonui i ka pono flocculation. I ka ʻoihana hana pepa, lawelawe ka alumini sulfate ma ke ʻano he mea nui no ka rosin sizing; hana ia me nā waikawa rosin e hana i nā kopa alumini insoluble, no laila e hoʻonui ai i ke kūpaʻa wai o ka pepa. Ma ke kahua o ka decolorization petroleum, hoʻohana ʻia nā waiwai adsorptive o ka hui e wehe i nā gums a me nā asphaltenes mai nā huahana aila. III. Nā Pono ʻenehana a me ka hana kūpono:
Ke hoʻohālikelike ʻia me nā flocculants ʻē aʻe (e like me nā paʻakai hao), loaʻa i ka aluminiuma sulfate nā ʻano penei: ʻO ka mea mua, ʻo ka colloidal aluminum hydroxide i hana ʻia i ka wā o ka hydrolysis e hōʻike ana i ka nui like o ka ʻāpana a me ka pono flocculation kiʻekiʻe, no laila e hōʻemi ana i ka nui o ka mea kemika e pono ai. ʻO ka lua, he pono ia ma kahi pae pH ākea (5.5–8.5), e hoʻopau ana i ka pono no ka hoʻoponopono nui ʻana i ka acidity a i ʻole ka alkalinity o ka wai. ʻO ke kolu, hiki ke wehe hou ʻia nā ion alumini koena ma o nā kaʻina hana lapaʻau ma hope (e like me ke kānana one a i ʻole ka adsorption kalapona i hoʻāla ʻia), no laila e hōʻemi ana i ka pilikia o ka haumia lua. Hōʻike nā ʻikepili hoʻokolohua i ka wā e mālama ai i ka wai muliwai turbidity kiʻekiʻe, hiki i kahi dosage alumini sulfate o 30-50 mg/L ke hoʻokō i ka nui o ka wehe ʻana o ka turbidity ma mua o 90%, e hōʻoia ana ua hoʻokō ka effluent i mālama ʻia i nā kūlana sanitary no ka wai inu home.
IV. Nā Kuhikuhi Palekana a me ka Mālama ʻana:
He mea nui e pale i ka mālama pū ʻana me nā kumu ikaika a i ʻole nā ​​mea hoʻoheheʻe oxidizing ikaika e pale aku i nā hopena exothermic. Pono e maloʻo ka wahi mālama a mālama ʻia ma kahi mahana ma lalo o 50°C e pale aku i ka huahana mai ka omo ʻana i ka makū a me ka caking. I ka wā e lawelawe ai, pono e ʻaʻahu i nā mīkina lima pale a me nā goggles palekana e pale aku i ka hanu ʻana i ka lepo a i ʻole ka pili ʻana i ka ʻili. Inā pili ulia pōpilikia me nā maka, e holoi koke me ka nui o ka wai maʻemaʻe a e ʻimi i ke kōkua lapaʻau. I ka wā e lawe ana, pono e hana i nā hana palekana e pale aku i ka huahana mai ka makū a me ka hōʻino kino, e hōʻoia ana i ka pono o ka ʻōpala.
