Lab Testing
FKC offers no cost dewatering evaluations to potential customers. Lab testing of samples helps to determine polymer requirements, potential screw press performance, screw press sizing, screw press materials requirements and other important factors. After lab testing and an initial proposal, in many cases it is beneficial to conduct an on-site trial with an FKC test trailer.

Lab Testing Photo Sludge Samples

Instructions for sending samples to be lab tested:
What: Any material(s) requiring thickening or dewatering with a rotary screen thickener and/or screw press.
Ship to: FKC Co., Ltd.
2708 W. 18 th Street
Port Angeles, WA 98363
Tel: (360) 452-9472
Amount: 3–5 gallons is sufficient. If the sludge consistency is below 1% then send at least 5 gallons. If multiple materials are to be mixed prior to dewatering then separate 3–5 gallon samples of each material should be sent. They can then be mixed at a known mix ratio in our lab.
When: Samples should be sent to FKC Monday—Wednesday. Shipments on Thursday or Friday are discouraged because they could remain in transit over a weekend.
How: Ship via courier such as FedEx, UPS etc. Biological sludges should be shipped overnight. Please call and inform us when the shipment is expected to arrive.
Packaging: Any leak-proof container will work. Plastic buckets are the most commonly received containers. Containers will not be returned unless prior arrangements have been made.
Other: Please notify FKC at (360) 452-9472 or mail@fkcscrewpress.com when sending a sample. This ensures time is set aside to test your sample while it is fresh.
Complete (as much as possible) and return an FKC Application Information Sheet or provide required design information.

If you are currently dewatering and using polymer please include a sample of neat polymer.
