Multi-media filters or ultrafiltration (UF) pre-treatment offer benefits for your Systems including lower membrane fouling, reduced cleaning costs, increased the flux, increased membrane life and longer membrane warranty. Depth filters offer superior SDI reduction, the lower pressure drop with greater dirt holding capacity and up to twice the life of conventional depth filters. RO membranes offer a broad portfolio of high rejection brackish water membranes. Several low energy and low fouling membranes are available to reduce overall plant costs.  S-RO Series is a range of reverse osmosis (RO) machines and components such as multi-media filters, carbon filters, water softeners, chemical feed systems, tanks, and pumps. When combined, these components deliver a full-scale, configurable water system.

As experts in total dissolved solids removal and deionization, UMT offers solutions that encompass water reuse and conservation throughout your operations, optimization of existing water production, and design and construction of new, energy efficient and environmentally friendly desalination processes. With speedy response and reliability, UMT can be your one source accountable for components, membranes, system performance, and more product offerings cover each stage of your fully integrated deionization process. To help plan your system, we analyze your water requirement, test your source water, evaluate your potential for reuse and conservation, and perform a treatment cost-benefit analysis.
