12 Common Problems and Causes of Reverse Osmosis Equipment

Released Date: Dec 01,2015 Article Source: Yuanlai Water Treatment
Reverse osmosis equipment is to pass the raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc. Then, it is pressurized by a pump and uses reverse osmosis membranes (RO membranes) with a pore size of 1/10,000 μm to turn high-concentration water into low-concentration water. At the same time, it isolates a large amount of industrial pollutants, heavy metals, viruses and other impurities mixed in the water. So as to meet the physical and chemical indicators and hygiene standards for drinking water and produce pure water. Reverse osmosis equipment is commonly used in the electronics industry, pharmaceutical industry, beverage industry, seawater, brackish water extraction, and domestic water supply, etc. Now let's talk about 12 common problems and causes of reverse osmosis equipment. 1. Low water supply pressure; The feed water flow rate is inappropriate. B  System leakage; C  Insufficient inlet water pressure of the high-pressure pump or leakage at the pump section

Reverse osmosis equipment is to pass raw water throughFine filters, granular activated carbon filters, compressed activated carbon filters, etc., are then pressurized by a pump, and the pore size is utilized1/10000μmReverse osmosis membraneROThe membrane can turn water with a higher concentration into water with a lower concentration, and at the same time isolate all impurities such as industrial pollutants, heavy metals, and viruses that are mixed in the water in large quantities, thereby meeting the physical and chemical indicators and hygiene standards for drinking water and producing pure water.

Reverse osmosis equipment is often used in the electronics industry, pharmaceutical industry, beverage industry, seawater, brackish water extraction, and domestic water supply, etc. Let's talk about it below12aCommon Problems and Causes of Reverse Osmosis equipment.

I.Low water supply pressure

The feed water flow rate is inappropriate;

System leakage;

The inlet water pressure of the high-pressure pump is insufficient or there is water or air leakage in the pump part;

The filter element of the precision filter is clogged with dirt;

The high-pressure pump is faulty.

Ii.High water supply pressure

The outlet door of the high-pressure pump is improperly adjusted;

The pipe between the high-pressure pump and the reverse osmosis unit is clogged;

If the concentrated water regulating door is closed too tightly or blocked, the concentrated water discharge flow will be small;

The recovery rate is too low.

Iii.Low recovery rate

The feed water flow rate is too high.;

The water supply pressure or concentration is low.

FourHigh recovery rate

The water supply pressure is too high;

Insufficient feed water flow rate;

V.The pressure drop at both ends of the reverse osmosis equipment is high

The flow rate of concentrated water is high;

Membrane element contamination;

SixThe high-pressure pump has stopped running

The outlet pressure of the pump is too high(Greater than1.7MPa);

The inlet water pressure of the pump is too low(Less than0.05MPa).

Vii.The water output of the reverse osmosis equipment has decreased

The feed water temperature is low.;

Low water supply pressure;

High concentration of concentrated water causes high osmotic pressure;

Membrane fouling.

Viii.The water output of the reverse osmosis equipment has increased

High water supply pressure;

The water supply temperature is high.

IXThe conductivity of the produced water and the concentrated water of the reverse osmosis equipment both increase simultaneously

The concentrated water pipeline or the concentrated water regulating valve is clogged with dirt;

The recovery rate is too high.

X.The reverse osmosis equipment has a high electrical conductivity in the produced water, a high electrical conductivity in the concentrated water, and a high pressure drop in each section

Membrane element contamination limits the flow rate of concentrated water.

ElevenThe electrical conductivity of the water produced by reverse osmosis equipment is high, the pressure drop at both ends of each pressure vessel increases, and the flow rate of the product water is low

Membrane element contamination.

TwelveThe pressure drop at both ends of each pressure vessel is large, the flow rate of the product water is low, and the conductivity of the product water increases somewhat

Contamination and blockage of membrane element channels.

EDI ultra-pure water system

EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

Non-negative pressure water supply equipment

Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

Constant pressure water supply equipment

Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
