Aluminium Oxide Powder Separation at Sandvik Asia
The Separator is used for a special application viz. separation of Aluminium Oxide powder from water. The Al Oxide powder is used in grinding processes as an abrasive, due to its hardness & strength.
The Al oxide slurry, after the process, was being discarded to the ETP. This increased the load on the ETP and also amounted to a lot of water wastage.The Separator System is provided with a centralized collection tank. Al oxide slurry, from the process, is collected in this tank. The Separator gets activated when the centralized tank gets filled-up. The slurry is efficiently cleaned by the Separator. The Separator shuts-off when the slurry in the tank reaches the low level.
The Al oxide powder slurry is cleaned efficiently, the dewatered powder is collectedand the clean water recycled for process use. Thus effectively reducing the load on ETP and ensuring savings in water and powder
Separator installation for Effluent Recycling
Paper Industry is a very water intensive industry. Huge amounts of water are required daily to process the paper pulp. With the scarcity of water, high costs and stringent effluent regulations, the paper industry faces many challenges.
Aquarius has been instrumental in evolving a “Zero Discharge” system for this industry.
Normally, the treated water from the ETP passes through the filter press and is drained.
Aquarius suggested their special continuous operation centrifuge after the filter press. The separator cleans the water from the filter press at a very high efficiency, without the need of any filter media. There is no possibility of choking and the thoroughly cleaned water is supplied to the subsequent water treatment equipment. This combined system has produced excellent results. The crystal clear recycled water has been tested vigorously and found to be suitable for use in the process.
Such combined systems are applicable to all water intensive industries and the “Zero Discharge” will help in paving way to a cleaner and pollution free environment.
Graphite Powder Separation
An auto part forging company uses graphite powder for lubrication during forging process. The same is washed with water and the mixture is stored in drums for disposal. The water could not be sent to their ETP due to the graphite powder contamination.
Aquarius suggested the semi-automatic separator for continuous cleaning of the storage tank. The high-efficiency cleaning allows the cleaned water to be sent to the ETP plant. A substantial disposal cost is saved accordingly.
