Tohkemy SMF Cassette System Water Treatment Systems

Manufacturer: Tohkemy Corporation
Model: SMF Cassette System

Features

Achieves high flux by special membrane formation
Flux: Approximately 4 times compared to the conventional products.
Achieves excellent washing ability by using water and air together
Achieves effective turbidity discharge by bubbling and backwashing with permeated water.
Capable of removing Cryptospodium and Legionella
Since SMF-PVDF has a nominal pore size of 0.05 μm, it is possible to remove Cryptosporidium and Giardia, which are the enemies of drinking water, and Legionella, which is the enemy of hot bath facilities and cooling towers.

Applications

Decontamination and infection control for water and beverage facilities
Circulation and Filtration for Hot Bath Facilities and Pools
Pretreatment of RO membrane equipment
Aseptic seawater production* [fishery processing]
*Pretreatment may be required.

*1 Calculated based on the filtration water volume of the test module at a supply pressure of 0.2 MPa and water temperature of 25℃.
*2 The filtration flow rate varies depending on operating conditions such as raw water quality, water temperature, supply pressure, and backwash conditions. This value is a guideline. Please consult our sales representative during the design phase.
Furthermore, conducting a membrane filtration test using the actual raw water allows for determining the precise design filtration flow rate, backwash conditions, and other operating parameters. We offer membrane filtration testing for a fee.
*3 This refers to seawater after pretreatment, such as sand filtration.
