Implementation Process
1. Initial Consultation
We consult with you to determine whether membrane filtration is appropriate for the type of raw water, the purpose of membrane filtration, and whether there is any pre-treatment or post-treatment. If the water has a good track record, we can calculate and propose the number of membrane modules needed and water recovery rates based on information such as water quality. We also offer complete system sales for select products. This can reduce the time and effort required for design by the customer. We will ask you about your requests in detail at the hearing.
2. Lab-Scale Filtration Test
Depending on the filtration target, lab-scale modules may be used to actually filter raw water to check performance. The number of membrane modules required is estimated by evaluating the degree of clogging caused by filtration. The filtrate water quality is also analyzed to confirm whether the water quality meets the requirements. If you send us the target raw water, we can perform a filtration test in Kuraray's laboratory (fee-based). If the raw water cannot be taken outside, we also sell lab modules so that testing can be performed in the customer's laboratory.
3. Pilot-Scale Filtration Test
A testing machine with one module for use in actual equipment can be rented (fee-based). When water quality fluctuates widely or when the scale of the facility is large, it is possible to reduce the risk of problems by conducting continuous testing on a multi-month basis. Technical support by skilled engineers is also available.
4. Revised Proposal and Design Support
We will make a proposal again after receiving the results of the lab-scale and pilot-scale tests. We also support planning and design for equipment installation, contributing to smooth equipment introduction.
5. Order and Delivery
If you are satisfied with our proposal, you place an order and we deliver the membrane modules to the location you specify.
6. After-Sales Support
Membrane analysis of your product is available in Kuraray's laboratory (fee-based). For products where the element can be removed from the housing, hollow fiber membranes can be cut for analysis and repaired using a dedicated jig, allowing analysis without membrane replacement.
- Elemental analysis of fouling substances (mainly inorganic)
- Scanning electron microscopy (SEM) observation of clogged membranes
- Membrane deterioration assessment
- Optimization of chemical cleaning conditions
- Other (please feel free to contact us)
We also provide total solution for post-delivery problems, such as determining the appropriate time for membrane replacement or membrane fouling due to unexpected fluctuations in water quality.
