Application of pretreatment system for raw water in pure water equipment Raw water pretreatment system Raw water pretreatment system as pure water equipment pure water equipment production relies on is very important. Whether it is industrial pure water equipment or drinking pure water equipment, raw water treatment pretreatment system is essential. A very important index involved here is "conductivity." In general, the lower the conductivity, the purer the water. The water treatment process currently used is a reverse osmosis system. The water treated by the reverse osmosis system generally achieves a 90%-99% salt rejection rate. Dongguan Green Health Water Treatment Company is a component of the pretreatment system in this reverse osmosis system pure water equipment. 1. Quartz sand filter 3. Dosing system 4. Precision filter Insect net greenhouse also known as plant and vegetables greenhouse net. Used for prevent the insect fly into the greenhouse during the plant growing, and cover the plants. Key off the approaches that the pests (adult insect) breeding. Effective control of the spread of all kinds of harmful pests spread, such as Cabbage caterpillar, diamondback moth, aphids, flea beetles, Sweet agnates, American leaf miner, literal etc and prevent the harmful of virus spread. Significantly reduced the use of chemical pesticides, so that the planting vegetables good-quality and health.

This equipment is mainly used to filter sediment, microorganisms and dust in the water to make the raw water clear. Raw water usually contains fine particles of dust, humus, starch, cellulose, and microorganisms such as bacteria and algae.
2. Activated carbon filter
The equipment is mainly used to filter residual chlorine in water. When the influent water inlet index, the residual chlorine is <50.1mg/L. The activated carbon filter has two main functions:
1. Adsorption of some organic matter in water, the adsorption rate is about 60%;
2. Adsorb the residual chlorine in the water. Five-component colloids, organic colloids, and dissolved organic polymer impurities and residual chlorine having a particle size of about 10 to 20 angstroms are difficult to remove in a mechanical filter. In order to further purify the raw water to achieve the reverse osmosis water inflow index, a primary activated carbon filter was designed in the process. The reason why the activated carbon can adsorb the active material with a particle size of several tens of angstroms is due to the large amount of its structure. The pore size and the grain gap with an average pore diameter of 20-50 angstroms, the structural characteristics of the activated carbon, can make the surface adsorption area reach 500-2000 M2/G, because the molecular diameter of the general organic matter is slightly less than 20-50 angstroms. Therefore, the adsorption of organic matter by activated carbon is most effective. In addition, the activated carbon has a strong dechlorination ability. The activated carbon is not simply adsorbed in the whole adsorption dechlorination process, but is catalyzed on the gas surface. Therefore, the activated carbon does not have the problem of adsorption saturation, but only a small amount of carbon is lost. Therefore, dechlorination of activated carbon can run for a long time. In addition to dechlorination and adsorption of organic matter, activated carbon can also remove odor, color, and residual turbidity in water. After a certain period of time, activated carbon will still weaken its adsorption capacity and require regeneration. Through the quartz sand filtration and activated carbon filtration, the purity of the raw water is greatly improved. The residual chlorine content in the treated water is <0.1mg/L
Working principle The feeding system is mainly used for the integrated dosing device for water treatment agent addition. In addition, according to the requirements of customers, the dosing control system can also be equipped with equipment and components such as liquid medicine tank and electronic control system. The pulsating driving force is generated by the electromagnet, and the driving link drives the diaphragm to reciprocate in the pump head, causing the volume and pressure of the pump head cavity to change, thereby causing the liquid suction valve and the liquid discharging valve to automatically open and close, thereby realizing the quantitative suction of the liquid and discharge. Microprocessor monitoring, safe and reliable. In the open-loop proportional dosing mode, the flow sensor (pulse flow meter) measures the actual flow value of the treated medium (such as water) in real time, and the dosing control system automatically and proportionally and accurately adds the chemical liquid according to the added concentration set by the customer. The whole process does not require manual intervention and is fully automated.
The water treatment system usually uses fine filtration as the source water to enter the final treatment process of the reverse osmosis membrane glue to prevent possible leakage in the previous process to prevent the reverse osmosis membrane from clogging.
