Hoʻopuka pinepine nā mea silika polycrystalline i ka pauka i ka wā e ʻoki ai.I ka wā e hele ai i kahi scrubber, hoʻopuka pū ia i ka nui o ka wai ʻino.Ma ka hoʻohana ʻana i kahi ʻōnaehana dosing kemika, ua hoʻokahe ʻia ka wai ʻino e ʻike i ka hoʻokaʻawale mua ʻana o ka sludge a me ka wai.

ʻO ka sludge i hana ʻia nā hiʻohiʻona kiʻekiʻe o ka hoʻoheheʻe wai a me ka haʻahaʻa haʻahaʻa haʻahaʻa, e hopena i ka mālama wai liʻiliʻi.Me kēia ʻano sludge i ka noʻonoʻo, hoʻohana kā mākou hui i kahi lole kānana me kahi kiʻekiʻe kiʻekiʻe kiʻekiʻe, i hui pū ʻia me ka hoʻonohonoho ʻana o ka roller kūpono.A laila, e hele ka sludge flocculated ma nā ʻāpana haʻahaʻa haʻahaʻa, medium-pressure, a me ke kaomi kiʻekiʻe, no ka ʻike ʻana i ke kaʻina hoʻoheheʻe ʻana i ka lepo.

Ua kūʻai kekahi hui i helu ʻia ma Xuzhou i ʻehā HTE-2000 kāʻei kānana paʻi i ʻOkakopa, 2010. ʻO ka hoʻonohonoho ʻana i nā lako ma ka pūnaewele a me ke kiʻi ʻana i ka hopena lapaʻau e hāʻawi ʻia ma lalo nei.
