Introduction: : E-Coat Cleaners, ElectroCoat Cleaners

General Chemical’s line of E-Coat Cleaners are water based, acidic materials formulated to remove uncured cathodic electrostatic paint build-up. These cleaners contain no chlorinated solvents or anhydrous silica. They are non-toxic, low odor materials that are used to clean heat exchanger plates and tubes, tank walls, car carriers, pumps, piping and spills on the floors as well as ultra filtration systems.

Electro deposition works much like a plating process. The parts (cathode) to be coated serve as one electrode and the auxiliary electrodes (anode) serve as the oppositely charged pole as displayed by the following diagram.

Ineffective cleaning and membrane fouling problems are not unusual. In e-coat operations. General Chemical helps customers get the most from their Membranes by solving their most complex cleaning and Fouling problems.
Inorganic foulants, heavy metals, oil and grease will reduce membrane performance over time. General Chemical’s e-coat membrane cleaners are especially formulated to clean and enhance the performance of tubular, spiral, hollow-fiber and flat sheet configuration used for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes and enhance performance.

Standard Cathodic E-coat Element Cleaning Procedure Guidelines

The mechanics of the cleaning procedure is generally the same for most systems, the following procedure is specific to the General Chemical e-coat Concentrate cleaner chemistry. The procedure is based on cleaning one eight inch or two six inch cartridges at a time with an individual cartridge cleaning system. You should feel free to modify the mechanics – not the chemistry – to accommodate your specific cleaning system.

1. Isolate the cartridge to be cleaned from the paint manifolds (feed, return, and permeate).

2. Initial Flush Procedure: Drain paint from the cartridge and follow up with a D.I. water flush to drain. Cartridge should be flushed until water runs clear. If the flush is to be done using a tank and a pump, adjust the pH to the paint tank (or lower) is preferred.

3. Final Flush Procedure:
Fill: cleaning tank with D.I. water and adjust pH to approximately 2.0 – 2.2
Open: cleaning return
Open: permeate to cleaning tank
Close: cleaning feed
Start Pump: slowly open the cleaning feed valve
Circulate pH adjusted D.I. water at ambient temperature for about 5 minutes and drain. Close the cleaning inlet valve. 4. Preparation of Cleaning Solution: Prepare a 200-liter cleaning solution by mixing the cleaner in the cleaning tank based on a 99:1 dilution. The 200-liter quantity is based on the cleaning of one eight or two six nch cartridge at a time. NOTE: Be sure to leave at least 20 cm of space at the top of the cleaning tank to accommodate foaming. 5. Cleaning Procedure: Raise the temperature of the cleaning solution to 100-105 degrees Fahrenheit either by heating or closed loop circulation.

Subsystems: Observe any confined space conditions. Use the appropriate safety equipment & clothing for the task.
