Abstract
The present invention provides a novel filter for filtration and recovery of suspended particles in water, which can filtrate the suspended particles in water simply and fast as well as recover the particles efficiently, and a method for filtration and recovery. The method involves the process of physically filtrating suspended particles in water using a filter comprised of soluble powder layered on a support and then dissolving the soluble powder of the filter in acid to recover the suspended particles filtrated.
Claims19
A filter for filtration and recovery of suspended particles in water, wherein the filter is comprised of soluble powder layered on a support.
A method for filtration and recovery of suspended particles in water, comprising:
- a filtration step of physically filtrating suspended particles in water using a filter comprised of soluble powder layered on a support;
- and
- a recovery step of dissolving the soluble powder of the filter to recover the suspended particles that are filtrated.
A method for water quality management, comprising the steps of:
- allowing water to pass through a filter comprised of soluble powder layered on a support;
- replacing the filter every predetermined time or every predetermined flow rate;
- storing the soluble powder of the replaced filter for predetermined period of time;
- and
- dissolving the arbitrary stored soluble powder and recovering suspended particles which are filtrated for analysis.
