Titanium anodes for water treatment often use iridium tantalum and ruthenium iridium coated titanium electrodes, which are mainly used in electrolytic sterilization, wastewater oxidation, ion water preparation, sewage descaling, electrochemical water treatment and other scenarios. Standardized use can greatly extend the electrode life and improve treatment efficiency. The usage methods mainly include installation, power on operation, and daily maintenance.
Before installation, it is necessary to check the appearance of the anode to confirm that the coating is intact without peeling, scratches or damage, and that the titanium substrate is not corroded or deformed. Fix the electrodes according to the equipment layout, maintain uniform spacing between the anode and cathode, avoid electrode contact short circuit, use corrosion-resistant copper bars or titanium wires for connection, firmly connect the wires, and prevent virtual connection and sparking. When the electrode is immersed in water, all active coating areas must be submerged in water, and it is strictly prohibited to apply electricity to dry areas to avoid high-temperature burning of the coating; Avoid collision and friction during installation to prevent coating scratches.
When running with power on, inject the water to be treated first, confirm that the liquid level meets the standard before turning on the power, gradually adjust the current and voltage to avoid sudden high current impact on the electrodes. According to the regulation of water quality, the current density should be controlled within a reasonable range for conventional water treatment. For strong acid, high salt, and high pollutant water quality, the current should be reduced to minimize electrode loss. Maintain the flow and circulation of water during operation, reduce impurities from adhering to the electrode surface, and prevent scaling and sludge coverage from affecting the electrolysis effect.
Daily maintenance requires regular cleaning of electrode surface dirt, scale, and microbial membranes. Low pressure water rinsing can be used, and stubborn attachments can be gently wiped with weak acid. It is forbidden to use hard objects to polish coatings. When shutting down, cut off the power first, then drain or keep the water submerged. If it is not used for a long time, it should be cleaned and stored dry to avoid moisture corrosion. It is strictly prohibited to reverse the positive and negative poles during use to prevent rapid peeling and failure of the anode coating.
Reasonably controlling installation spacing, operating current, and cleaning maintenance can fully leverage the advantages of titanium anode corrosion resistance, high catalysis, and long service life. It is suitable for various water treatment conditions such as circulating water, sewage, swimming pool water, and drinking water disinfection.
