TRIDENT Water Systems
Electro Contaminant Removal Unit
Introduction. The ECR uses the principal of passing DC charge through the water between a series of sacrificial plates to induce the release of metal ions to cause a reaction resulting in the coagulation/flocculation of particles. The basic principal is to cause electrons (amps) to flow through the liquid. The reaction takes place on the surface interface between liquid and plates. The physical reactions take place within a chamber that contains the metal plates and the water to be treated. The chambers are custom made from FRP and come in 2 sizes. Chambers can be connected in a modular fashion accomodate higher flow rates.
ECR Consumables. The conductive material in the ECR unit will dissolve and provide a coagulation nucleus from the plates like Fe++ and Al +++. Because the conductive material dissolves and must be replaced periodically, the form of that material has direct operating cost considerations. The Trident ECR uses mild steel and/or aluminum plates cut to the required size. Such mild steel/aluminum plates are readily available at a reasonable cost. On average, it takes less than 0.04kg of mild steel to treat a m3 of water. The Trident units use standard 3mm thick mild steel/aluminum plates.
Surface Area Configuration.The treatment occurs at the surface interface between the liquid and the conductive material. Flat plates allow distances to be set that are far enough apart to lessen the clogging caused by large particles in the water, and close enough together to lessen the amount of voltage required to move the electricity through the liquid. The Trident ECR chamber is designed with flat plates located between 3mm to 6mm apart, depending on type of water being treated and incorporates inherent self cleaning mechanism.
Vertical Flow. The Trident ECR chamber directs water flow in the same direction as air bubbles float. This directional flow helps to minimize build up of solids on the plates and makes cleaning of the plates less often and a much simpler procedure. This saves both time and labor.
Electrical Connections. The Trident reactor (chamber) and its bipolar design allows direct line voltage to be converted from AC to DC. This saves the weight and space of electrical transformers. This also allows for the energy efficiency of operating the power at low voltage(<3V) per gap between plates. The electrical cost savings depends upon the voltage difference applied between the conductive materials.
Flow Rate. Trident ECR chambers come in 2 sizes with a basic flow rate of 5-15m3/hr and 10-30m3/hr. The chambers are modular in design and can be inter-connected to scale up the flow rate as desired coupled with the appropriate ECR power panel. The size of the chamber takes into consideration weight and size of the steel plates to enable a single operator to handle the unit. Multiples of 20 can be configured with a corresponding scaling up of the electrical panels.
Reverse Polarity. To maximize the usage of the plates and minimize fouling on the plates, the Trident ECR unit will automatically reverse the polarity of the plates on a set period. This ensures that both sides of the plates are evenly used. The Triden ECR unit incorporate a unique electrical controller enabling current reversal ina quick and safe manner; there in allowing continuous and uninterrupted treatment.
Performance. The Trident ECR unit is designed to remove a whole spectrum of contaminants from waste waters including COD/BOD, Heavy Metals, Color, O&G and many others.
