1. Modular design, compact structure, beautiful layout, convenient operation and maintenance.
2. The double softeners in pretreatment unit can realize series operation and alternate regeneration by using valve group. Each water softener has 100% water supply capacity. The whole process of softener operation, backwashing, salt absorption, regeneration and washing is fully automatic and programmed.
3.Frequency conversion control is adopted for raw water pump, RO1 and RO2 high-pressure pumps, which can not only realize different pressure control of filter and softener under various operating conditions, but also realize low-speed and small circulation of produced water in system standby time, greatly reducing the probability of microbial breeding and effectively saving energy.
4. The terminal water production of the system adopts a dual-channel water supply and single-channel circulation mode, that is, when the product water is qualified, it enters the purified water storage tank through two pipelines. While when the product water is unqualified, the product water circulates through the two pipelines and then flows back to the middle water storage tank. When the purified water storage tank is full, it will automatically switch to the circulation pipeline operation, which effectively avoids the existence of empty pipes and ensures that there is no dead water.
5. The middle water storage tank is used as the buffer tank to realize online cleaning, eliminating the separate cleaning system. The system can choose thermal disinfection RO membrane and thermal disinfection EDI to realize online hot water sanitization of the whole system.
6. As far as possible, use stainless steel pipes to directly stretch the elbow to avoid welding seam. Welding parts of pipelines and accessories should be automatically welded with argon protection(single-side welding and double-side forming process) to ensure welding quality, and electrochemical polishing after welding.
7. Provide endoscopy photos, solder joint diagram, pressure test and pickling passivation report, system design documents and other verification data.
