The Model T70GD4000 chlorine dioxide generator is designed to produce and consistently maintain a product yield greater than 95%, which makes it ideal for drinking water treatment. It is a two-chemical system, utilizing diluted concentrations of hydrochloric acid and sodium chlorite in the production of chlorine dioxide. No chlorine gas is required. A proven design, durable construction and the use of the best available corrosion-resistant materials assure efficient gas production, precise solution feeding, low maintenance and dependable operation for the life of the equipment.
The Model T70GD4000 chlorine dioxide generator is an all liquid system. Research has shown a market trend towards chlorine dioxide generators that do not require chlorine gas for the production of chlorine dioxide. This system is designed for use with 8.5% hydrochloric acid and 7.5% sodium chlorite, fed at a 1:1 ratio. The generator design combines vacuum technology with dosing pump flexibility to generate chlorine dioxide from low hazard (diluted) sodium chlorite and hydrochloric acid.
The Model T70GD4000 chlorine dioxide generator is available with either manual or automatic control. Both methods of control are performed using Biochem, a microprocessor based control system. The Biochem includes a keypad for manual control. In the case of automatic control, the Biochem accepts a 4-20 mAdc input signal. The Biochem provides alarm contacts for pump failure, low vacuum condition and low reagent flow.
