1、 Process flow

1Quartz sand filter

Quartz sand filter is a common fast filtration equipment that uses quartz sand filter material to remove suspended solids from raw water. When water containing suspended particles flows through the filter layer, the gaps in the filter material screen and filter the suspended particles, making them easy to adsorb on the surface of the filter material. When a certain amount of dirt is trapped on the surface of the filter material to form a filter membrane, the pressure difference before and after the filter will quickly increase over time until it fails. At this point, it is necessary to use reverse water flow to backwash the filter material, causing the quartz sand in the filter to suspend and loosen, thereby stripping off the trapped substances adhering to the surface of quartz sand and anthracite and carrying them away by the water flow, restoring the filtering function. Design flow rate of 15m/h, backwash intensity of 15-18L/m2. s. The NTU of the effluent from the quartz sand filter is less than 1. The wear of quartz sand decreases after long-term use, and quartz sand should be replaced every 5-7 years. Backwash drainage is connected to the water storage tank.

2Activated carbon filter

The operation of activated carbon filters is accomplished through a carbon bed. The activated carbon particles that make up the carbon bed have many micropores and a huge specific surface area, and have strong physical adsorption capacity. Water passes through a charcoal bed, and organic pollutants in the water are effectively adsorbed by activated carbon. In addition, there are some oxygen-containing pipe clusters on the non crystalline part of the surface of activated carbon, which effectively adsorb organic pollutants in the water passing through the carbon bed by activated carbon. Using activated carbon to remove low molecular weight organic matter, free chlorine, odorous substances, and heavy metal ions from water. Design flow rate of 15m/h, backwash intensity of 10L/m2. s. Replace the activated carbon filter material around 1 year.

3Precision filters

The function of a precision filter is to intercept particles larger than 5 μ m from the previous system to prevent large particles from entering the reverse osmosis membrane. After being accelerated by a high-pressure pump, these particles may penetrate the first stage reverse osmosis membrane components, causing a large amount of salt leakage and scratching the impeller of the high-pressure pump. The filter element in the filter is a replaceable cartridge filter rod, which should be replaced when the pressure difference between the inlet and outlet of the filter is greater than the set value (usually 0.07-0.1Mpa). When installing the filter element, it should be aligned vertically, otherwise it will damage the filter element and, more seriously, lose its filtering function

4Fully automatic water softener

The fully automatic softener is made in the United StatesFleck5600Program controlled valve automatic control, regeneration cycle is12～24hourFleck5600The control valve adopts a time mode to start regeneration, with accurate measurement. The workstation consists of six steps: operation, backwashing, regeneration, slow washing, fast washing, and salt tank water injection. The conversion of power position is automatically recorded by the time controller in the automatic control valve. When the processed water volume reaches the pre-set value of the program, the controller sends a command signal to the driving motor, and the motor rotates to drive the multifunctional valve core to rotate, changing the flow direction of inlet and outlet water, thus achieving automatic control. Regenerated salt solution is sucked in by negative pressure through a water sprayer, without the need for a salt pump. Daily maintenance only requires adding salt to the salt tank. The function of a softener is to remove waterCa2+TheMg2+to preventCaCO3andCaSO4Sedimentation on the concentrated water side of the membrane can form scale and block the channels of the concentrated water membrane, affecting the water production and quality of reverse osmosis.

5Reverse osmosis

Reverse osmosis is currently the membrane separation technology with the highest filtration accuracy. His filtering accuracy has reached0.0001um.After filtering all substances in tap water, there are no minerals or trace elements, and this type of water can be consumed directly,

Separate pure water from a solution containing solutes using a semi permeable membrane that can only pass through water. At this point, the water on the pure water side spontaneously penetrates the semi permeable membrane and enters the solution side, causing the water level on the solution side to rise. This phenomenon is called permeation. When the liquid level rises to a certain height, the pressure on both sides of the membrane reaches equilibrium, and the liquid level on the solution side no longer rises. At this point, there is a pressure difference on both sides of the membrane, called osmotic pressureIf a pressure greater than the osmotic pressure is applied to the solution side, the water molecules in the solution will be squeezed to the pure water side, which is exactly the opposite of osmosis. We call this processreverse osmosisWe can see from the process of reverse osmosis that due to pressure, water molecules in the solution enter pure water, increasing the amount of pure water while the solution itself is concentrated. The reverse osmosis membrane used in this device is a semi permeable spiral wound membrane. When raw water is sent to the reverse osmosis membrane at a certain pressure, the water passes through the small pores on the membrane and is collected to obtain pure water. Impurities in the water, such as soluble solids, organic matter, colloidal substances, and bacteria, are collectedreverse osmosisMembrane interception, concentrated and removed in the intercepting liquid.primary reverse osmosisCan remove raw water97%The above soluble solids.
