The first step in the selection of single-stage reverse osmosis equipment must give priority to completing a complete test of the full index of raw water quality.Factories in different regions of Shaanxi use their own groundwater, and the hardness and TDS values of water quality vary greatly.If the TDS of raw water is not higher than 1000mg/L, and the conductivity of production water is required to be stable at 10-50µS/cm, the selection of RO reverse osmosis equipment can meet the needs of most ordinary industrial production water.If the test finds that the hardness of raw water is too high, it must be equipped with a complete set of quartz sand filtration, activated carbon adsorption, and softening pretreatment units. You must not just stare at the purchase price of the reverse osmosis host to pressure the budget. If the pretreatment configuration is not in place, it will directly cause serious pollution and blockage of the RO membrane within 3-6 months or even directly scrapped.

The second step is to accurately determine the actual required water production, and not only refer to the nominal tonnage parameters of the equipment.The factory must first calculate the average daily water consumption per hour, and at the same time reserve 15-20% of the water production margin to cope with the sudden water demand during the peak production period.The conventional recovery rate of a single-stage reverse osmosis system is recommended to be controlled in the range of 50-70%. Blindly and forcibly increasing the recovery rate of the system will greatly increase the risk of fouling of membrane components.In terms of automated configuration, factories that require continuous production are recommended to be equipped with PLC automatic flushing and high and low voltage linkage protection functions to greatly reduce the workload of manual duty.In food production scenarios, 304 stainless steel is preferred for equipment pipelines and racks, which fully comply with food-grade water safety regulations.
It is easy for many customers to step on the pit in the selection stage: they only compare the quotation of the reverse osmosis host horizontally, completely ignoring the quality of the core accessories and the adaptability of local working conditions.A set of RO reverse osmosis equipment with stable operation, membrane components, high-pressure pumps, and scale-blocking dosing systems must be targeted to match the local water quality conditions in Shaanxi. Foreign general-purpose equipment often does not consider the impact of low temperature in northwest winter on water production flux, and the actual water output will be significantly reduced after it is shipped to the local area for actual operation. The problem.
Project case: Single-stage pure water project of a daily chemical processing plant in Xianyang
A local daily chemical processing plant in Xianyang requires pure water supply for the production of ingredients and product cleaning. The raw water is taken from the factory's own groundwater. The water quality test results show that the hardness is significantly high, and the average daily demand for pure water is about 20 tons.The company purchased a simple water purification device on its own in the early stage, and the salt content of the effluent was unstable for a long time. The final daily chemical products occasionally had unexplained defects, which directly affected the product pass rate.
The company contacted Xi'an DIEN Water treatment in the follow-up. After our technical personnel took samples and completed the full index water quality test, they configured a pretreatment softening system with a complete set of 3 tons per hour single-stage RO reverse osmosis system.The equipment adopts a fully automatic operation mode, which is fully adapted to the continuous production rhythm of the factory's two shifts.After the project is officially put into use, the conductivity of the water produced has been steadily maintained at 20-30µS/cm for a long time. (Click to learn: The standard conductivity of the effluent quality of the reverse osmosis equipment is normal) It fully meets the production water standards of the daily chemical industry. The RO membrane has been in continuous operation for more than a year without serious fouling problems, and the replacement cycle of consumables is fully in line with the pre-design expectations, completely solving the production problem of white spots and defects in the effluent of the product.
The Shaanxi factory purchases single-stage RO reverse osmosis equipment. Raw water quality testing is a prerequisite for all selection work. Redundant space must be reasonably reserved for water production, and the core configuration of pretreatment must not be saved.Factories with conditions try their best to choose local manufacturers who are familiar with the characteristics of local water quality in the Northwest. If you have the relevant needs of industrial pure water projects, you can contact DIEN water treatment professional and technical personnel to issue a fully adapted customized landing plan according to the actual production conditions of the factory.
