Desalination of seawater - Import export

Introducing the Diamond Series Fresh Water Maker, a state-of-the-art reverse osmosis system designed for marine applications. This system offers a nominal production capacity ranging from 40 to 80 cubic meters per day, ideal for use with seawater at a temperature of 25°C and a salinity level of 35,000 parts per million. Housed within a durable stainless steel rack, this system is skid-mounted for easy installation and comes equipped with an integrated PLC control and starting cabinet for user-friendly operation. One of its standout features is the automatic freshwater flushing system, which serves as a safeguard for the membranes, prolonging their lifespan. Additionally, it boasts an automatic "water drop" system with a high salinity alarm, ensuring the quality of the produced water. To enhance performance monitoring, the unit is fitted with a digital flow-meter, providing precise readings of both momentary and cumulative water production.

In the treatment of drinking water, whether done conventionally or via seawater desalination, agitators are used for rapid mix, precipitation and flocculation processes. Precipitation and flocculation processes require low shear, slow-running agitators. For pH adjustments and rapid mixing faster running agitators that can blend reactor content in a flash are required. Wastewater treatment also requires a multitude of application options for agitators. In anaerobic and anoxic tanks for nitrogen removal, slow-running agitators are used to suspend and homogenize activated sludge flocs. In aeration tanks, mixer/aerators can be used for efficient oxygenation and mixing. Where waste water is purified, sludge is generated. This sludge is generally conditioned using polymers, dewatered, and then digested in anaerobic sludge digesters to generate biogas. Special agitators are required for both polymer introduction and for digested sludge mixing.
