The product (see figure below) is a system device base on the principles of Flow Reversal technology, enabling improved performance for membrane-based desalination systems. The system can be introduced to RO plants either as a retrofit or as grassroots plant design. Implementing these new technologies leads to: increasing in process recovery - thus dramatically reducing brine volumes requiring disposal, minimization of anti-scalant consumption, and significant reduction in desalination costs. The product integrates a manifold of pipes with valves (A) with an algorithm-based control device; Regular RO plant design (B) can be adapted to Flow Reversal technology to obtain Tapered-Flow RO desalination plants (C).

Advanced Oxidation Processes (AOP) refers to a set of chemical treatment procedures enhanced by Ultra sound and UV activation, designed to remove organic and inorganic materials in waste water.

The VSEP technology has developed as an alternative method for producing intense shear waves on the face of a membrane. The technique is called Vibratory Shear Enhanced Processing (VSEP). In a VSEP System, the feed slurry remains nearly stationary, moving in a leisurely, meandering flow between parallel membrane leaf elements. Shear cleaning action is created by vigorously vibrating the leaf elements in a direction tangent to the faces of the membranes.

Plug & play device for monitoring water scaling potential.

Ultrasonic sensor and smart algorithm for monitoring, detection, prevention and control of pipe scaling.

AST - mobile containerized ‘plug & play’, portable water systems mobile water purification units supply fresh drinking water from any water source, anywhere. Mobile units can produce drinking water from almost any source including seawater, surface water, and brackish water. Produced water meets World Health organization (WHO) drinking water quality guidelines. AST water mobile purification units have maintained potable water supply following natural disasters and humanitarian crises. Emergency drinking water was provided to international relief organizations in the wake of the Indian Ocean tsunami, after flooding in Bangladesh and for refugees in Kosovo, Albania, and Sudan.

The basic concept of the ROTEC system is smart `flow reversal`. To avoid scaling, the system alternates the desalination process direction flow (switching of the entrance and exit of the feed stream) before reaching the critical point in which scaling forms. Flow reversal at the induction time halts the crystallization of minerals, lowers salinity levels in feed water and `cleans` membranes and pipes. While simple in concept, this operation is complex to implement and requires a gradual and precise process that can be hazardous to the desalination plant equipment if not properly performed.

Smart pressure housing incorporates embedded ultrasonic sensors to signal fouling status of desalination membrane elements. The harness of the sensors is installed on the outside of an existing pressure vessel with null detection principle, can be applied to a vessel in service.

In light of successful results both in sensing the beginning of scaling on flat sheet surfaces, spiral-wound RO membranes and even the inner surface of pipes, and considering the huge market potential of scale sensing technology and the great interest and enthusiasm form relevant market sector.

WellToDo developed a unique process to convert various common water contaminants into nonpolluting compounds. The process utilizes a novel catalyst developed by WellToDo that enables a chemical reaction used to remove the contaminants. The main benefit of this method is that it removes water contaminants without generating any brine or byproducts.
