System Features
The relevant equipment of the system realizes automatic operation through liquid level interlocking, with aut
omatic functions (automatic water production, automatic flushing, automatic shutdown of raw water shortage / full water tank, high and low pressure alarm, etc.).
The design of the actuator adopts standardized, generalized and systematic parts to facilitate disassembly, replacement, and cleaning of parts.
Compact system layout, small footprint, effective space saving.
The system has low energy consumption and can effectively save energy.
Long life of consumables and low water cost.
The system operates reliably, the water supply pipeline is closed, and the effluent water quality is stable.
Use non-polluting materials.
Process flow
This project recommends the use of an advanced, mature, stable effluent water quality and stable system operation reverse osmosis desalination device as the system's pure water preparation equipment; the system has low operating costs, is easy to implement automation, and has good economics. The product water treated by the two-stage reverse osmosis device meets the process water requirements by UV sterilization.
In order to ensure the long-term reliable and stable operation of key equipment, such as a two-stage reverse osmosis device, a pretreatment system is set up to meet the reverse osmosis membrane (RO) water inlet index: turbidity <0.5NTU, SDI <4, and residual chlorine <0.1ppm. According to the raw water quality, the pretreatment system consists of raw water tank, raw water pump, multi-media filter, activated carbon filter, softening filter, security filter and related auxiliary equipment.
