Cov khoom thaiv yas yuav tsum tau npaj rau hauv qhov chaw zoo thiab lub qhov dej kom zoo. Yog hais tias nws yog nyob rau hauv lub caij kub, nws yog qhov zoo tshaj plaws kom npaj cov tej kas tham nyob rau hauv tshwj xeeb sheds nrog plaub sab kom tsis txhob kub ntau cuam tshuam kev loj hlob ntawm unicellular algae. Ua ntej ua haujlwm, yuav tsum ntxuav tes, thiab muab cov dej cawv cuaj caum pov tseg. Cov daus thiab cov daus ntawm cov kab lis kev cai thiab cov ntsuas lub khob los ntsuas cov ntsev, cov ntaub qhwv thiab cov nylon zaj duab xis thiab lub tshuab nqus dej ntawm lub qhov ncauj yuav tsum tau muab tshem tawm. Siv tom qab ua npau dej thiab tshuaj tua kab mob. Kev nthuav kab lis kev cai yog npaj los ntawm purifying thiab filtering lub seawater los ntawm boiling, txias thiab ntxiv nutrient ntsev. Txuas ntxiv mus thaum nruab hnub, nres thaum hmo ntuj, thiab tsis mob thaum tav su thaum lub caij sov. Yas nruas yuav tsum raug muab suav thiab cim nrog hnub uas nthuav dav kom lub thoob yas thooj ntu hluav taws xob tuaj yeem siv tau qhov kev txiav txim siab ntawm kev nthuav dav. Lub raj mis-rau-fwj, chim-rau-fwj, thiab lub fais fab-mus-tank yog qhov ua tiav tsis tu ncua. Algae hom yuav tsum yog ntshiab thiab nyob hauv kev loj hlob theem exponential, thiab cov laus cov kab mob uas tsis muaj hnub nyoog yuav siv tsis tau rau txoj kev tsis sib haum.
Cov khoom ntawm lub thoob yas yog feem ntau tshuab moulded thiab txhaj molded los ntawm plastics xws li polyethylene thiab polypropylene. Dab tsi yog lub ntsiab khoom high-density polyethylene rau ua barrels yas? Cia wb mus saib:
Cov tshuab moulding qib hollow yas thawv ua los ntawm cov low-pressure high-density polyethylene, uas yog, HDPE, high-density polyethylene (HighDensity Polyethylene, hu ua "HDPE"), uas yog lub high-crystallinity, cov thermoplastic uas tsis yog resin. Tus HDPE thawj yeej muaj cov xim dawb thiab pom ib qho zoo nkauj hauv seem thin. PE muaj kev tiv thaiv zoo rau feem ntau ntawm cov yam ntxwv ntawm kev noj haus thiab muaj chemical. Qee hom tshuaj muaj peev xwm ua rau cov tshuaj lom neeg muaj corrosion, xws li oxidants corrosive oxidants (concentrated nitric acid), hydrocarbons (xylene), thiab halogenated hydrocarbons (carbon tetrachloride). Lub polymer tsis yog-hygroscopic thiab muaj cov dej zoo tsis haum thiab yuav siv tau rau ntim. HDPE muaj hluav taws xob zoo tshaj plaws, tshwj xeeb tshaj yog cov dielectric zog, ua nws haum rau xaim thiab cable. Nruab nrab rau qib siab phaus qib siab muaj kev ua haujlwm zoo heev, ob qho tib si ntawm ambient kub thiab txawm nyob tsis tshua muaj siab-40F.
