Comparison between organic sludge and organic matter / About effects of flocculants during drying process -3 After water treatment and dewatering process, organic sludge containing flocculants becomes granular as it is dried. However, organic matter containing no flocculants never becomes granular after being dried. It seems the effect of flocculants during drying process can be seen only […]
Comparison of drying between organic sludge and inorganic sludge after dewatering / About effects of flocculants during drying -2 There are mainly two types of sludge after water treatment and dewatering, and they are organic sludge and inorganic sludge. Both organic and inorganic sludge are sticky and adhesive before drying, and there is not so much […]
About effects of flocculants during drying 1) What is flocculants? Flocculant is a chemical to assemble scattered particles about the cloudy water in water treatment plant etc. and to makes clusters, then the clusters are settled out of water. The cluster made by assembled particles are called aggregates or flocs. By settling down the particles, it […]
Food processing plant sludge drying Comparison of the drying by the difference in steam pressure Drying in steam pressure 0.5Mpa Drying in steam pressure 0.7Mpa Material to be dry: Food processing plant sludge Purpose of drying: Compost from waste products Moisture content: 85.2％W.B. before drying, 5.4％W.B. after drying (0.7Mpa) Requirements for dryer: No clogging inside of […]
Drying of sugar mill sludge / Example of drying test Material to be dry: Sugar mill sludge Purpose of drying: Fuel from waste products Moisture content: 70％W.B. before drying, 20％W.B. after drying Requirements for dryer: No clogging inside of the dryer since materials being dried are adhesive. 24-hour unattended operation. No change in components of […]
