ʻO ka mea i kapa ʻia ʻo slurry-water slurry e pili ana i kahi slurry i hana ʻia me 70% pulverized lanahu, 29% wai a me 1% chemical additives ma hope o ka hoʻoulu ʻana. He wahie wai ia e hiki ke puhi a ehu e like me ka aila wahie. Hiki ke lawe ʻia a mālama ʻia ma kahi lōʻihi, a ua like kona waiwai calorific me ka hapalua o ka aila wahie. Ua hoʻohana ʻia ia i loko o nā pahu ʻaila maʻamau i hoʻololi ʻia, nā kapuahi ʻino, a me nā kapuahi hoʻouka wikiwiki ʻano kaulahao. Ke hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana o ka lanahu a i ʻole liquefaction, maʻalahi ke ʻano o ka hoʻoili ʻana o ka lanahu-wai, ʻoi aku ka liʻiliʻi o ka hoʻopukapuka kālā, a haʻahaʻa hoʻi ke kumukūʻai, no laila, mai ka wā i kūkulu ʻia ai i ka waena o 1970s, ua huki ʻia ka manaʻo o nā ʻāina he nui. He ʻāina hana lanahu nui koʻu ʻāina. Ua hoʻokomo kālā ʻoi aku ia ma kēia wahi a ua loaʻa ka ʻike waiwai. I kēia manawa hiki nō ke hana i ka slurry lanahu-wai kiʻekiʻe mai ka pauka lanahu i hana ʻia e ka holoi lanahu.
ʻO nā mea hoʻohui kemika o ka slurry wai lanahu e komo maoli i nā dispersants, stabilizers, defoamers a me nā corrosive, akā ma ke ʻano maʻamau e pili ana i ʻelua ʻano o nā dispersants a me nā stabilizers. ʻO ke kuleana o ka mea hoʻohui: ma kekahi ʻaoʻao, hiki ke hoʻopuehu like ʻia ka lanahu pulverized i loko o ka wai wai ma ke ʻano o kahi ʻāpana hoʻokahi, a i ka manawa like, pono ia e hana i kahi kiʻiʻoniʻoni hydration ma ka ʻili o ka. ʻāpana, i loaʻa i ka slurry wai lanahu kekahi viscosity a me ka wai;
Ma kekahi ʻaoʻao, ʻo ka slurry lanahu-wai i kahi kūpaʻa e pale ai i ka ua o nā ʻāpana lanahu pulverized a me ka hoʻokumu ʻana o ka crusting. ʻO nā mea ʻekolu i loaʻa i ka CWS kiʻekiʻe ka manaʻo kiʻekiʻe, ka wā paʻa lōʻihi a me ka wai maikaʻi. ʻElua mau kī no ka hoʻomākaukau ʻana i ka slurry lanahu-wai kiʻekiʻe: ʻo ka maikaʻi o ka lanahu maikaʻi a me ka hāʻawi like ʻana i ka nui o ka pauda lanahu, a ʻo kekahi mea hoʻohui kemika maikaʻi. ʻO ka ʻōlelo maʻamau, paʻa ka maikaʻi o ka lanahu a me ka nui o ka pauka lanahu, a ʻo ia ka mea hoʻohui.
I mea e hōʻemi ai i ke kumu kūʻai o ka slurry wai lanahu, i nā makahiki i hala iho nei, ua pili nui kekahi mau ʻāina i ka noiʻi a me ka noi ʻana o ka humic acid a me ka lignin ma ke ʻano he mea hoʻohui, hiki ke hana i nā mea hoʻohui me nā hana dispersant a me ka stabilizer.
