The delivery meets both my time expectations and the product requirements. The customer service department has been an excellent support during the process of selecting the right sample products for my target market and setting up the sample delivery.

we tested PAC and PAM combination for food pressing wastewater. Coagulation and flocculation worked very well during treatment. I was very satisfied with the results. The sales manager Eric provided an excellent service, not only answered my technical questions professionally, but also sent us more products for trials. I highly recommend the products and sales services from this company.
