Product Profile

The large-scale reverse osmosis plant has a relatively large water output and is generally used in larger production enterprises. The EcoLan series large-scale reverse osmosis device can provide high-quality pure water for many industries and meet the production water needs of enterprises. The reverse osmosis unit mainly removes impurities such as dissolved salts, organic matter, silica colloids, bacteria, viruses, macromolecules, and particles not removed by pretreatment to obtain pure water. In addition, the two-stage reverse osmosis process can further remove the ions in the water so that the effluent can meet the feed water requirements of the subsequent EDI device process.

Product Features

PLC Programmable Intelligent Control System and Human-Machine Interface Operating System

It has LCD liquid crystal display, man-machine dialogue, clock, and language setting function. After the start-up, the electronic control system of the equipment automatically detects and puts in the chemicals automatically and proportionally, fully automatic treatment of raw water and preparation of pure water.

Online Water Quality Detection and Control to Ensure Water Quality Meets Requirements

Equipped with high-quality product water and concentrated water flow meter, raw water and product water conductivity meter, and pH meter for real-time detection of water quality and system water yield and recovery rate to ensure the regular operation of the reverse osmosis system and the production of pure water to meet the requirements.

Automatic Flushing Function and Advanced Membrane Protection System

Configure chemical cleaning system, inlet water, and drainage pressure gauge, continuously monitoring the pressure difference of reverse osmosis membrane, prompting timely cleaning and automatic flushing. Built-in advanced membrane protection system, when the equipment turns off, it can automatically flush the dirt on the membrane surface with product water to prolong the service life of the reverse osmosis membrane.

Personalized Design to Meet Local Water Quality and Meet Demand in All Aspects

Reverse osmosis water treatment equipment can be designed according to the needs of different projects and the local water quality. At the same time, the degree of integration is high and easy to expand. Increasing the number of reverse osmosis membranes can increase the processing capacity to meet customer needs.

High efficiency, Low Noise High-Pressure Pump

Adopting high efficiency and good quality high-pressure pump, PLC automatically controls start and stop, which reduces energy consumption and operating noise. Meanwhile, the built-in low-pressure switch protects the high-pressure pump from damage due to water supply stoppage.

Process Flow Diagram

The raw water (tap water, surface water, groundwater) goes through a pretreatment system and precision filter. Then, the water is sent to the reverse osmosis device through a high-pressure pump to prepare the product water directly. It is a primary reverse osmosis, suitable for the water quality with a conductivity of less than 300μs/cm, and the product water conductivity is less than 10μs/cm. The first-stage reverse osmosis product water can also be filtered by one more reverse osmosis unit, the second-stage reverse osmosis system to meet better effluent conductivity requirements.

Product Specification Selection

We have several options for standard membranes, and we can customize sizes per customers’ requests. Please note that the membrane is calculated by square meters for each layer of membrane filaments.
