Small-Scale Reverse Osmosis (RO) Equipment

Small-Scale Reverse Osmosis (RO) Equipment Manufacturer

Membrantec’s small-scale reverse osmosis water treatment equipment can fulfill the need for pure water with comparatively low water consumption. Like the large-scale reverse osmosis system, this compact equipment is a comprehensive water treatment system built around the reverse osmosis membrane. It encompasses the pretreatment phase, the reverse osmosis membrane filtration phase, the post-treatment phase, and the system cleaning phase. However, its primary function is using the reverse osmosis membrane to retain inorganic salt ions such as calcium and magnesium in the water. This process reduces the conductivity of raw water to below 10μs/cm, thereby meeting the quality standards for production usage and ensuring the safety and stability of pure water.

Product Features

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

The equipment features an LCD liquid crystal display, human-machine dialogue, clock, and language setting function. Upon activation, the electronic control system automatically detects and dispenses chemicals in a proportional manner. It handles the treatment of raw water and preparation of pure water fully automatically.

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

The equipment is fitted with high-quality product water and concentrated water flow meters, raw water and product water conductivity meters, and a pH meter. These components allow for real-time detection of water quality, system water yield, and recovery rate, ensuring the steady operation of the reverse osmosis system. This guarantees the production of pure water that meets all necessary requirements.

Automatic Flushing Function and Advanced Membrane Protection System

The equipment is configured with a chemical cleaning system, inlet water, and drainage pressure gauge. It continuously monitors the pressure difference of the reverse osmosis membrane, prompting timely cleaning and automatic flushing. It also features an advanced built-in membrane protection system. When the equipment is turned off, it can automatically flush away any dirt on the membrane surface using product water. This helps to prolong the service life of the reverse osmosis membrane.

Small Size of Equipment, Simple Installation and Maintenance, Unattended

With its compact design, small footprint, and easy operation, the equipment can function fully automatically, resulting in a low operating cost. This allows for unattended usage.

Pretreatment Equipment Tank Material Optional

Given the same configuration, customers have the flexibility to choose between FRP and stainless steel as their tank material. Compared to FRP, stainless steel can withstand higher temperatures and tremendous pressure, catering to the more demanding needs of users.

Process Flow Diagram

The raw water (tap, surface, and 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. To meet better effluent conductivity requirements, the first-stage reverse osmosis product water can also be filtered by one more reverse osmosis unit, the second-stage reverse osmosis system.
