Geomembrane Kenya rau Tailings Treatment Project
Geomembranes tau siv dav hauv tailings kho tej yaam num los muab ib tug barrier thiab ntim system rau kev cia thiab tswj ntawm kuv tailings. Hauv Kenya, yog tias koj tab tom nrhiav geomembranes rau txoj haujlwm kho tailings, muaj ntau txoj hauv kev los xav txog.
Cov neeg muab khoom hauv zos: Pib los ntawm kev tiv tauj cov chaw muag khoom hauv zos thiab cov chaw tsim khoom ntawm geomembranes hauv Kenya. Lawv tuaj yeem muab koj cov ntaub ntawv hais txog hom geomembranes uas lawv muab, lawv cov specifications, thiab tus nqi.
Thaum xaiv ib lub geomembrane rau koj qhov project kho tailings, xav txog cov hauv qab no:
Cov Khoom Siv: Geomembranes muaj nyob rau hauv cov khoom sib txawv xws li high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), polyvinyl chloride (PVC), thiab ethylene propylene diene monomer (EPDM). Txhua yam khoom muaj qhov sib txawv thiab tsim nyog rau kev siv tshwj xeeb. Xaiv cov khoom siv geomembrane uas ua tau raws li qhov yuav tsum tau ua ntawm koj qhov project kho tailings.
Thickness thiab Strength: Xav txog lub thickness thiab lub zog yuav tsum tau ntawm lub geomembrane raws li tej yam xws li qhov tob ntawm tailings, txoj kab nqes stability, thiab tej zaum yuav cuam tshuam ib puag ncig. Thicker thiab muaj zog geomembranes feem ntau yog siv rau kev xav tau ntau dua.
Kev Txhim Kho thiab Vuam: Xyuas kom meej tias tus neeg muag khoom tuaj yeem muab cov neeg ua haujlwm cob qhia lossis kev taw qhia txog cov txheej txheem kev teeb tsa kom raug thiab cov txheej txheem vuam. Geomembranes feem ntau yog sib koom ua ke los ntawm cov cua sov los yog tshuaj welding los tsim ib qho kev thaiv tsis tu ncua.
Cov Qauv Zoo: Txheeb xyuas tias cov geomembranes muab tau raws li cov qauv zoo thiab cov ntawv pov thawj. Nrhiav cov khoom lag luam uas ua raws li cov qauv thoob ntiaj teb xws li ISO 9001 rau kev tswj hwm zoo thiab ISO 14001 rau kev tswj hwm ib puag ncig.
Nws yog ib qho tseem ceeb rau kev koom tes nrog cov kws tshaj lij lossis cov kws pab tswv yim txog kev kho mob tailings kom paub meej tias qhov kev xaiv tsim nyog thiab kev teeb tsa ntawm geomembranes. Lawv tuaj yeem muab cov lus pom zoo tshwj xeeb raws li qhov chaw nyob, cov kev cai tswj hwm, thiab qhov project specifications.
BPM Geosynthetics, tsim nyob rau hauv 2007, tau tshwm sim los ua ib tug ua chaw tsim tshuaj paus thiab tsum ntawm HDPE liners. Lawv txoj kev cog lus los muab cov kev pabcuam dav dav hauv kev tshawb fawb, kev tsim kho, tsim khoom, muag, thiab xa tawm cov ntaub ntawv geosynthetic tau ua rau lawv muaj zog thoob ntiaj teb cov neeg siv khoom. Nrog ib pab neeg ntawm 120 tus kws tshaj lij cov kws tshaj lij tshwj xeeb hauv cov ntaub ntawv geotechnical, BPM Geosynthetics ua kom muaj kev txawj ntse hauv lawv cov khoom. Lawv cov chaw tsim khoom lag luam nthuav dav tshaj 16, 000 square metres thiab tau nruab nrog cov cuab yeej siv hluav taws xob tsim hluav taws xob thiab cov cuab yeej ua haujlwm tshaj lij.
BPM Geosynthetics muab qhov tseem ceeb ntawm cov khoom tsim kho tshiab, kev ruaj ntseg zoo, thiab cov neeg siv khoom txaus siab. Lawv cov khoom lag luam suav nrog cov geomembranes du, geomembranes ntxhib, sib xyaw geomembranes, geotextiles, bentonite waterproof pam, geogrids, cov kav dej, thiab lwm yam. Cov khoom no tau dhau los ua kev sim nruj thiab tau txais ntawv pov thawj xws li IS09001 rau kev tswj xyuas zoo, IS014001 rau kev tswj ib puag ncig, OHSAS18001 rau kev noj qab haus huv, thiab ntawv pov thawj los ntawm GAILAP, Soncap, SASO, BV, SGS, Intertek, thiab lwm lub koom haum muaj koob npe.
Cov ntawv thov ntawm BPM Geosynthetics 'geomaterial cov khoom muaj ntau haiv neeg, nrhiav kev siv hauv aquaculture, landfills, biogas digesters, dej phwj tuaj, cov kav dej, kev tsim vaj tsev hauv nroog, tsuas, kev tsim vaj tsev, thiab lwm yam. Lawv siv zog ua tus khub txhim khu kev qha, muab cov nqi-zoo thiab tshiab HDPE liners thiab geomaterial series cov khoom, nrog rau cov khoom zoo heev thiab kev pabcuam tom qab muag.
Nrog rau lawv txoj kev tsom mus rau cov neeg siv khoom txaus siab thiab lawv cov khoom lag luam uas tau lees paub, BPM Geosynthetics yog qhov chaw zoo kom tau raws li cov kev xav tau ntawm cov neeg siv khoom hauv kev lag luam geosynthetic.
