Forsta engineers are always trying to find ways to improve the robustness of typical wear parts. Research is conducted on filters in test conditions that simulate the most adverse real-world operating environments. The in-house testing has the goal of ongoing R & D to contribute to design upgrades. By subjecting equipment to the harshest environments possible, engineers are able to design for long-lasting component life. Test units are operated in a high pressure, high solids system using water that contains abrasive particles such as sand and silica. The continuous backwash test guarantees high-performance and durability of filter components even during upset conditions. The rigorous testing is used to ensure that Forsta equipment will not suffer during seasonal/periodic spikes in particle loading that may force the filter into high frequency cleaning.
