Soil amendment is one of the most effective methods to improve saline-alkali soil. In this study, laboratory experiments were conducted verify effect 13 kinds amendments and their combinations (Citric acid (NM), Phosphogypsum (LS), Aluminum sulfate+citric (AL+NM), sulfate+phosphogypsum (AL+LS), acid+phosphogypsum (HH), Zeolite (Z), Acidified zeolite (ZH), sulfate (AL), sulfate+zeolite (AL+Z), s...

Industri tahu di Kelurahan Gunung Sulah yang dijalankan masih berskala rumah tangga dan home industri. Hingga saat ini belum dilakukan pengolahan limbah cair, baik cara fisik, kimia, maupun biologis. Peneliti bertujuan mengetahui efektifitas koagulan <em>Polyaluminium Chloride (PAC)</em> dalam cair industri tahu. Eksperimen menggunakan rancangan <em>Pretest-Posttest</em>...

In the Centro de Ingeniería Sanitaria a process named ARCIS-UNR was developed for arsenic and fluorine removal from groundwater by means of coagulation with polyaluminium chloride (PACl) and double filtration. A treatment plant for 11,200 inhabitants was designed. During monitoring of the plant it was needed to get more data regarding removal mechanisms and relevant variables in coagulation-ads...

During toxic Microcystis aeruginosa blooms, large amounts of cells can enter sediment through natural settlement, and coagulation treatment used to control water blooms can enhance the accumulation of cells. However, the current understanding of the fates of these cells and associated microcystins (MCs), as well as the effect of coagulation treatment on these factors, is limited. The results of...

Sucralfate, a complex polyaluminium hydroxide salt of polysulphated sucrose, is used in medical treatment of peptic disease as a coating agent that provides a protective barrier to further damage from acid and pepsin. Its actions are principally local and at acid pH becomes highly polar and binds by way of strong electrostatic interaction to ulcer tissue for up to 12 hours, while relatively lit...

The present research introduces adsorption of sulfonated cobalt phthalocyanine catalyst (Europhtal) from the real wastewater that is produced in mercaptan removal unit (Merox) third refinery, South Pars Gas Complex (SPGC), Assaluyeh, Iran. Therefore, novel low-cost natural zeolite modified with polyaluminium chloride (PAC) was investigated as an adsorbent for treatment Europhtal wastewater. Cen...
