Continuous Electrodeionization CEDI Module

CEDI Modules are the latest technology in Electrodeionization. They simply offer Continuous operation with no need for regeneration of the resin which saves a lot of time and money. Learn more about Continuous Electrodeionization by clicking on this link.

BQUA in conjunction with market experts in the field of CEDI proudly offers a premium line of CEDI modules. With advanced technology and learning the market needs, we give you reasons to choose BQ-ED over other CEDI Modules present in the market:

1. Junction box is separated with water nozzles to prevent electric leakage, while other CEDI modules’ junction box is below water inlet. Meaning any water leak may cause electric shock.
2. Quick connector, easy to get power supply and avoid the wrong wire connection. In other CEDI Modules you need to open the junction box cover to get power supply.
3. Professional hoisting mode, others have special handles.
4. Saving installation space, easy to tighten.
5. Thicker end plate to improve strength and protect water nozzles.
6. Dimension size is lengthened, 316L stainless steel material.
7. Standard adapter from English size scale to metric standard,while other companies only make English size scale.

BQ-ED Modules are designed to be installed in either single or multiple Continuous Electrodeionization Module orientations. BQ-ED modules represent compact state-of-the-art design assures ease of installation, maintenance, and service. The CEDI module sizes are designed in optimal flow configurations stated below to ensure cost effectiveness. Table below shows model numbers and nominal flow rates.

Feed Water Requirements CEDI Module – RO Permeate

Feed water for BQ-ED modules must always meet the specifications outlined in Table below:

In most cases, pre-treating BQ-ED modules feed water with reverse osmosis (RO) will bring it within these specifications. Depending on the conditions, however, some sites may require additional pre-treatment. In order to determine if additional pre-treatment is required, below is a feed water requirements reference to compare the BQ-ED feed water (RO Permeate) on site.

Feed Water Source	RO Permeate
Feed Water Conductivity	<40 uS/cm
Silica (SiO2)	<1 ppm
Iron (as Fe, Mn, S)	<0.01 ppm
Maximum Total Chlorine (as Cl)	<0.02 ppm
Total Hardness (as CaCO3)	<1.0 ppm
Dissolved Organics (TOC as C)	<0.5 ppm
pH	4-11
Temperature	41-113 F (5-45 C)
Inlet Pressure	<100 psi (7 bar)

Tools and Equipment

• Dolly or fork lift for moving module into place
• Cords, cables or straps to secure to dolly / fork lift
• Wire cutters/strippers
• Adjustable torque wrench with 10-50 ft-lbs. (14-68 N-m) range, 3/8″ (10 mm) drive
• 19 mm extra deep socket
• 19 mm open end wrench
• Screwdrivers (flat blade and Phillips head)
• BQ-ED module handles for moving & positioning unit

Electrical and Plumbing Supplies

The amounts, sizes, and types of these supplies will vary from site to site. Check before hand to determine the site needs:

• Conduit, wires and appropriate conduit connectors to run the DC power and ground from the DC power controller to the module. Size wire in accordance with local electrical code.
• Fittings to connect the 1 1/4″ and 3/4″ BSPM ports on the module to the module plumbing.
