The choice of consumables for reverse osmosis water treatment equipment is so important, do you know these standards?
Reverse osmosis device uses membrane separation equipment, reverse osmosis water treatment equipment generally uses raw water pretreatment system software. Purification system software for reverse osmosis equipment. The post-purification system consists of three parts. In that case, why to set ro reverse osmosis preparatory processing, the following by us for you in detail.
ro reverse osmosis membrane is easily affected by suspended solids in water. Colloidal solutions. Environmental contamination by soluble polymers, which congregate on the surface of membranes. In the process of continuous separation, the residue on the surface of the membrane will converge more and more, resulting in film concentration. Raw water also contains a large number of bacteria and virus microbial strains, but also cause great damage to the membrane, serious harm membrane water purification performance and service life. Besides, the ambient temperature of the source water. PH value. Working pressure. The degradation of residual chlorine content and other parameters will also lead to membrane hydrolysis reaction, so the whole process of preparatory treatment must be set in the whole system to adapt to the regulations of water seepage and ensure the normal operation of equipment and the quality of effluent water.
RO reverse osmosis environmental protection treatment equipment
Quartz sand filter
At present, quartz sand filtration is an indispensable pretreatment system in water treatment equipment, the key to remove particulate matter suspended solids. According to the water demand, design the original water filter tank and filling material required specifications and technical parameters.
Multimedium filter
Quartz sand
Quartz sand filter equipment is a pressure filter, with refined quartz sand filled filter device. When water seepage from the top down filter layer, remove the suspended solids and cohesive particles in the water, reduce the turbidity of water, mainly used for water filtration solution.
Many water pretreatment choose quartz sand as a filter material, mainly considering its low price. Stable quality. Wear resistance, but there are some defects:
1. It's prone to bacteria. Pollute the water.
2. Low filtration accuracy (20μm-30μm)
3. The filtering effect is unstable, and it is very easy to caking. After 2-3 years, it is necessary to maintain the jumping insect regularly.
As a reverse osmosis device, it is much higher than other sewage treatment regulations, so the cost is much higher. Quartz sand filtration is an important part of preparatory treatment, and its excess quality is related to afterwater. Cost of removing and replacing filter materials.
Active filter material
Quartz sand
It is a carefully designed product, made of green and dark brown laminated glass that has been processed for the right size and appearance. Then carry on three step solution, complete from the surface disinfection sterilization, get excellent adsorption characteristics.
The advantages of using active filter materials and quartz sand in ro reverse osmosis preparation are as follows:
Security risks. To deal with many problems such as the reproduction of quartz sand bacteria in the filter.
Filtration accuracy increased from 20μm to 1μm(without coagulant)
Use cost problem. The key is to reduce the number of other filter material replacement. The filtration level was increased from 20μm to 1μm, which reduced the consumption of filtration materials in the middle and late stages. The second is to reduce the cost of the softener hydropower project by 50%; Finally, the labor cost and raw material cost of disassembling and replacing filter materials, as well as the rights and interests damage caused by the cessation of operation.
Summary:
The filtration system is suitable for ro reverse osmosis preparation. It overcomes the problem of no treatment of quartz sand and further improves the level of raw water pretreatment. Operating costs greatly reduced, the rate of return in the short term rich.
