Seawater RO Desalination for Coastal Greenhouse Irrigation

The Rise of Coastal Greenhouses A coastal greenhouse is a specialized agricultural facility located near the shoreline, designed to cultivate high-value crops (such as tomatoes, cucumbers, and strawberries) in controlled environments. These structures are most common in water-scarce regions like the Middle East (UAE, Saudi Arabia), North Africa (Morocco, Egypt), the Mediterranean (Spain, Greece), and Australia. The primary challenge for …

Large-Diameter Gate Valves at Raw Water Intake for Waterworks

As a type of linear-motion isolation valve, the gate valve can either completely shut off or allow fluid flow through a pipeline. It is commonly used for isolation operations in potable water supply systems and plays a critical role at the raw water intake head. In the primary pump station (raw water intake station) of a water treatment plant, large-diameter …

Butterfly & Check Valves for Secondary Water Supply Pump Rooms

The secondary water supply pump room serves as a pivotal component in ensuring consistent and reliable water delivery, particularly in high-rise buildings and remote areas where municipal water pressure is insufficient. This facility stores treated tap water in tanks and utilizes booster pumps to elevate water pressure, enabling it to overcome gravitational challenges and friction losses within vertical and extended …

Gate Valves for Waterworks

Gate valves in water distribution systems act as the critical “cut-off” points along water mains, service connections, and pipelines leading to treatment plants. Their main function is to provide a reliable, on/off mechanism to completely isolate sections of the network for maintenance, repairs, or system modifications without disrupting the overall pressure and flow in the remaining network. When a gate …
